X INTRODUCTION

In July 1985 Puss t ONeill Inc was retained on behalf

of the Bardanise Company to conduct a hydrogeologic

investigation of property located at 272 Main Avenue in

Norwalk Connecticut (Reference 1) The investigation

was undertaken voluntarily pursuant to and in compliance

with Connecticut Department of Environmental Protection

(DEP) Consent Agreement No 4109

The property is occupied by three buildings (Buildings 1

2 and 3) as shown on Plates 1 and 2 Building 3 is

located at 272 Main Avenue An earlier hydrogeologic

study conducted on behalf of Electric Indicator Co Inc

(Elinco a former division of EDO Corporation) which bull

had leased Building 3 from 1973 to 1986 demonstrated the

presence of volatile organic contaminants principally

trichloroethylene (TCE) tetrachloroethylene and

111-trichloroethane in the ground water immediately

west of Building 3 (Reference 2) In addition the study

documented two areas of soil contaminated with these same

volatile organic compounds These areas are located

immediately east of Building 3

The investigation conducted by Fuss amp ONeill Inc was

intended to examine the entire Bardanise Company property

0817CRSP1

w -1shy

which includes Buildings 1 2 and 3 (hereafter referred to

as the site or the property) with respect to volatile

organic contamination Major findings of the

investigation are summarized below

1 the unconaolidated materials at the site consist of

assorted sized sand gravel boulders and silt

designated as ice contact deposits Hydraulic

conductivity of this geologic unit is highly variable

depending on the degree of sorting by glacial

meltwaters The deposits range in thickness from 0 to

38 feet across the site

2 Bedrock at the site consists of weathered and bull

fractured gneiss Fracture orientation is generally

northwest to southeast Test drilling Indicates that

the bedrock surface slopes steeply to the west across

the northern portion of the site and to the northwest

across the southern portion beneath Building 3

3 Test drilling has shown that a high degree of

interconnection most probably exists between the

stratified drift deposits and the underlying bedrock

-2shy

4 Water levels indicate that ground-water flow

potentials are to the west-northwest at a gradient of

approximately 008 ftft Much of the ground-water

flow occurs exclusively in the shallow bedrock

fracture system particularly In the eastern and

southern portions of the property

5 Sampling of the unconsolidated materials conducted on

behalf of Elinco demonstrated elevated TCE levels in

soil samples obtained from the rear of Building 3

Analysis of soil samples from six locations in the

vicinity of Buildings 1 and 2 have shown relatively

low levels of TCE chloroform and nethylene chloride

at and near the water table bull

6 Water quality samples indicate that volatile organic

compounds principally TCE tetrachlorethylene and

111 trichloroethane ore present in the groundwater

beneath tiie site principally to the west of Buildings

1 and 3 and to a lesser extent between Buildings 1

and 3 These compounds have been detected both in the

unconsolidated sediments and the fractured bedrock

The highest concentrations of volatile organics are

present in the bedrock aquifer in the vicinity of

Building 3

-3shy

The hydrogeologic investigation wan submitted to DEP in

June of 1986 and approved in June of 1987 (see Appendix

A)

As a result of the hydrogeologic Investigation a response

action plan was prepared The plan was submitted to the

DEP Hazardous Waste Unit in April of 1987 A copy is

presented as Appendix B This plan was approved by DEP in

July of 1987 On October 21 1987 Elinco Associates the

new owner of the property entered into a consent

agreement with DEP to implement the approved response

action plan

This document is intended to serve as a ground-water

sampling and analysis plan for the Elinco Associates site

in compliance with step 1 of the October 1987 consent

agreement The scope of the plan is as follows

1 Provide background information on the geologic and

hydrogeologic setting of the facility

2 Establish and maintain precise techniques for

obtaining and preserving field samples and

bulleasurements which can be duplicated at each sairpjing

location Identified in the plan and during each

sampling period

-4shy

3 Establish a schedule for sampling and analysis

4 List required preservation and shipment techniques to

ensure samples maintain their natural composition

5 Establish a chain-of-custody control for samples with

documentation at each change of control point

6 Outline the required analytical procedure which will

be used for each sample

7 Establish the reporting requirements for the

ground-water monitoring plan

B Geology

1 Surficial

The area In the Immediate vicinity of the Ellnco

Associates site consists predominantly of two

types of surflclal geologic deposits (Reference

3) East and south of the site at a natural

elevation of 90 feet and above the surficial

deposits consist of glacial till with scattered

bedrock outcrops Till consists of

non-stratified heterogeneous material deposited

directly by glacial Ice

To the north and west of the property the

surficial geology consists of fluvial sand and

gravel characterized as ice contact deposits

These deposits originated during the last glacial

period in an environment where glacial neltwaters

were in close proximity to the existing ice mass

This association produced formations of extreme

complexity as climatic variations changed the

depositional environment under which the formation

was created The result is a geologic deposit

which can consist of well sorted sands and gravels

to silty till-like materials to boulders The

-6shy

hydraulic conductivity of these deposits is highly

variable with ground-water preferentially

migrating along zones of greatest transmissivity

2 Bedrock

The bedrock beneath the site consists of nixed

felsic gneiss (Reference 4) It is described as

medium to coarse grained and poorly to well

foliated An outcrop napped to the east of the

site indicates a strike orientation from north to

south with an easterly dip of 20 degrees An

outcrop observed immediately to the rear of

Ibull

Building 3 showed a strike orientation generally

i trending northwest to southeast

The Fuss amp ONeill hydrogeologic investigation

demonstrated that the bedrock slopes downward to

the north and west across the site

Correspondingly the thickness of the stratified

drift deposits increases toward the northwestern

portion of the site reaching a maximum of 38 feet

at the northwestern corner Rock coring indicates

that the shallow bedrock system beneath the site

is moderately weathered within its first 6 to 12

inches In addition it is moderately to highly

fractured to depths of at least 10 feet

-7shy

C Ground-Water Hydrology

Hater level measurements conducted as part of the Fuss

t ONeill hydrogeologic Investigation have

demonstrated that ground water flows In a

west-northwest direction across the site at a gradient

of approximately 008 feet per foot In general the

water table mirrors the configuration of the bedrock

surface As previously stated extensive fracturing

of the upper bedrock Implies that the unconsolidated

deposits and the bedrock are hydraulically

interconnected This is demonstrated by the fact that

the water table is first encountered within the

unconsolidated deposits over 40 percent of the site

and is entirely within the bedrock aquifer over the bull

remainder

D Surface and Ground Water Classifications

The DEP has classified all surface and ground waters

of the State according to existing water quality and

future water quality goals The Blinco Associates

bullite is located in a class GBCA ground water area

(Reference 5) This indicates bull current

classification of GB with a goal of GA By

definition a GB area Is located In areas where

historical industrial commercial or residential

-8shy

development has or Is likely to render the ground

waters unsuitable for drinking water without

treatment (Reference 6) A GA designation

implies ground waters which nay be suitable for

public or private drinking water use without

treatment (Reference 6) The GA goal is consistent

with the nearby Kellogg-Deering Wellfield a drinking

water supply for the area

DEP has assigned a surface water classification of B

for the portion of the Norwalk River nearest to the

site (Reference 5) Because the site is removed from

the river direct impacts were not considered during

the hydrogeologlc Investigation nor are they addressed bull

In this monitoring plan

-9shy

III MONITORING PLAN

The ground-water monitoring plan will Initially include

quarterly bullsapling of eight monitor wells on site The

locations of these wells are shown on Plate 2 Wells K-10

and K-ll also shown were installed under the supervision

of NUS Corporation in conjunction with an Environmental

Protection Agency (EPA) Investigation of the

Kellogg-Deering Wellfield and are unavailable for

sampling Table 1 presents a summary of monitor well

completion details including depths and screen settings

As noted in the table MW-2 was destroyed during the

recent construction activity on Route 7 Space

limitations following this construction preclude

replacement of the well KW-106 located adjacent to bull

MW-105 will be monitored for water levels only The

other eight walls listed on Table 1 will be sampled under

this plan for ground-water quality

Sampling would be conducted in March June September and

December beginning in December of 1987 and continuing for

a minimum of on year At any tine after the first year

of monitoring Elinco Associates may request modifications

with respect to the frequency of data collection or the

number of wells or parameters monitored

X INTRODUCTION

In July 1985 Puss t ONeill Inc was retained on behalf

of the Bardanise Company to conduct a hydrogeologic

investigation of property located at 272 Main Avenue in

Norwalk Connecticut (Reference 1) The investigation

was undertaken voluntarily pursuant to and in compliance

with Connecticut Department of Environmental Protection

(DEP) Consent Agreement No 4109

The property is occupied by three buildings (Buildings 1

2 and 3) as shown on Plates 1 and 2 Building 3 is

located at 272 Main Avenue An earlier hydrogeologic

study conducted on behalf of Electric Indicator Co Inc

(Elinco a former division of EDO Corporation) which bull

had leased Building 3 from 1973 to 1986 demonstrated the

presence of volatile organic contaminants principally

trichloroethylene (TCE) tetrachloroethylene and

111-trichloroethane in the ground water immediately

west of Building 3 (Reference 2) In addition the study

documented two areas of soil contaminated with these same

volatile organic compounds These areas are located

immediately east of Building 3

The investigation conducted by Fuss amp ONeill Inc was

intended to examine the entire Bardanise Company property

0817CRSP1

w -1shy

which includes Buildings 1 2 and 3 (hereafter referred to

as the site or the property) with respect to volatile

organic contamination Major findings of the

investigation are summarized below

1 the unconaolidated materials at the site consist of

assorted sized sand gravel boulders and silt

designated as ice contact deposits Hydraulic

conductivity of this geologic unit is highly variable

depending on the degree of sorting by glacial

meltwaters The deposits range in thickness from 0 to

38 feet across the site

2 Bedrock at the site consists of weathered and bull

fractured gneiss Fracture orientation is generally

northwest to southeast Test drilling Indicates that

the bedrock surface slopes steeply to the west across

the northern portion of the site and to the northwest

across the southern portion beneath Building 3

3 Test drilling has shown that a high degree of

interconnection most probably exists between the

stratified drift deposits and the underlying bedrock

-2shy

4 Water levels indicate that ground-water flow

potentials are to the west-northwest at a gradient of

approximately 008 ftft Much of the ground-water

flow occurs exclusively in the shallow bedrock

fracture system particularly In the eastern and

southern portions of the property

5 Sampling of the unconsolidated materials conducted on

behalf of Elinco demonstrated elevated TCE levels in

B Geology

1 Surficial

The area In the Immediate vicinity of the Ellnco

Associates site consists predominantly of two

types of surflclal geologic deposits (Reference

3) East and south of the site at a natural

elevation of 90 feet and above the surficial

deposits consist of glacial till with scattered

bedrock outcrops Till consists of

non-stratified heterogeneous material deposited

directly by glacial Ice

To the north and west of the property the

surficial geology consists of fluvial sand and

gravel characterized as ice contact deposits

These deposits originated during the last glacial

period in an environment where glacial neltwaters

were in close proximity to the existing ice mass

This association produced formations of extreme

complexity as climatic variations changed the

depositional environment under which the formation

was created The result is a geologic deposit

which can consist of well sorted sands and gravels

to silty till-like materials to boulders The

-6shy

hydraulic conductivity of these deposits is highly

variable with ground-water preferentially

migrating along zones of greatest transmissivity

2 Bedrock

The bedrock beneath the site consists of nixed

felsic gneiss (Reference 4) It is described as

medium to coarse grained and poorly to well

foliated An outcrop napped to the east of the

site indicates a strike orientation from north to

south with an easterly dip of 20 degrees An

outcrop observed immediately to the rear of

Ibull

Building 3 showed a strike orientation generally

i trending northwest to southeast

The Fuss amp ONeill hydrogeologic investigation

demonstrated that the bedrock slopes downward to

the north and west across the site

Correspondingly the thickness of the stratified

drift deposits increases toward the northwestern

portion of the site reaching a maximum of 38 feet

at the northwestern corner Rock coring indicates

that the shallow bedrock system beneath the site

is moderately weathered within its first 6 to 12

inches In addition it is moderately to highly

fractured to depths of at least 10 feet

-7shy

C Ground-Water Hydrology

Hater level measurements conducted as part of the Fuss

t ONeill hydrogeologic Investigation have

demonstrated that ground water flows In a

west-northwest direction across the site at a gradient

of approximately 008 feet per foot In general the

water table mirrors the configuration of the bedrock

surface As previously stated extensive fracturing

of the upper bedrock Implies that the unconsolidated

deposits and the bedrock are hydraulically

interconnected This is demonstrated by the fact that

the water table is first encountered within the

unconsolidated deposits over 40 percent of the site

and is entirely within the bedrock aquifer over the bull

remainder

D Surface and Ground Water Classifications

The DEP has classified all surface and ground waters

of the State according to existing water quality and

future water quality goals The Blinco Associates

bullite is located in a class GBCA ground water area

(Reference 5) This indicates bull current

classification of GB with a goal of GA By

definition a GB area Is located In areas where

historical industrial commercial or residential

-8shy

development has or Is likely to render the ground

waters unsuitable for drinking water without

treatment (Reference 6) A GA designation

implies ground waters which nay be suitable for

public or private drinking water use without

treatment (Reference 6) The GA goal is consistent

with the nearby Kellogg-Deering Wellfield a drinking

water supply for the area

DEP has assigned a surface water classification of B

for the portion of the Norwalk River nearest to the

site (Reference 5) Because the site is removed from

the river direct impacts were not considered during

quarterly bullsapling of eight monitor wells on site The

locations of these wells are shown on Plate 2 Wells K-10

X INTRODUCTION

In July 1985 Puss t ONeill Inc was retained on behalf

of the Bardanise Company to conduct a hydrogeologic

investigation of property located at 272 Main Avenue in

Norwalk Connecticut (Reference 1) The investigation

was undertaken voluntarily pursuant to and in compliance

with Connecticut Department of Environmental Protection

(DEP) Consent Agreement No 4109

The property is occupied by three buildings (Buildings 1

2 and 3) as shown on Plates 1 and 2 Building 3 is

located at 272 Main Avenue An earlier hydrogeologic

study conducted on behalf of Electric Indicator Co Inc

(Elinco a former division of EDO Corporation) which bull

had leased Building 3 from 1973 to 1986 demonstrated the

presence of volatile organic contaminants principally

trichloroethylene (TCE) tetrachloroethylene and

111-trichloroethane in the ground water immediately

west of Building 3 (Reference 2) In addition the study

documented two areas of soil contaminated with these same

volatile organic compounds These areas are located

immediately east of Building 3

The investigation conducted by Fuss amp ONeill Inc was

intended to examine the entire Bardanise Company property

0817CRSP1

w -1shy

which includes Buildings 1 2 and 3 (hereafter referred to

as the site or the property) with respect to volatile

organic contamination Major findings of the

investigation are summarized below

1 the unconaolidated materials at the site consist of

assorted sized sand gravel boulders and silt

designated as ice contact deposits Hydraulic

conductivity of this geologic unit is highly variable

depending on the degree of sorting by glacial

meltwaters The deposits range in thickness from 0 to

38 feet across the site

2 Bedrock at the site consists of weathered and bull

fractured gneiss Fracture orientation is generally

northwest to southeast Test drilling Indicates that

the bedrock surface slopes steeply to the west across

the northern portion of the site and to the northwest

across the southern portion beneath Building 3

3 Test drilling has shown that a high degree of

interconnection most probably exists between the

stratified drift deposits and the underlying bedrock

-2shy

4 Water levels indicate that ground-water flow

potentials are to the west-northwest at a gradient of

approximately 008 ftft Much of the ground-water

flow occurs exclusively in the shallow bedrock

fracture system particularly In the eastern and

southern portions of the property

5 Sampling of the unconsolidated materials conducted on

behalf of Elinco demonstrated elevated TCE levels in

soil samples obtained from the rear of Building 3

Analysis of soil samples from six locations in the

vicinity of Buildings 1 and 2 have shown relatively

low levels of TCE chloroform and nethylene chloride

at and near the water table bull

6 Water quality samples indicate that volatile organic

compounds principally TCE tetrachlorethylene and

111 trichloroethane ore present in the groundwater

beneath tiie site principally to the west of Buildings

which includes Buildings 1 2 and 3 (hereafter referred to

as the site or the property) with respect to volatile

organic contamination Major findings of the

investigation are summarized below

1 the unconaolidated materials at the site consist of

assorted sized sand gravel boulders and silt

designated as ice contact deposits Hydraulic

conductivity of this geologic unit is highly variable

depending on the degree of sorting by glacial

meltwaters The deposits range in thickness from 0 to

38 feet across the site

2 Bedrock at the site consists of weathered and bull

fractured gneiss Fracture orientation is generally

northwest to southeast Test drilling Indicates that

the bedrock surface slopes steeply to the west across

the northern portion of the site and to the northwest

across the southern portion beneath Building 3

3 Test drilling has shown that a high degree of

interconnection most probably exists between the

stratified drift deposits and the underlying bedrock

-2shy

4 Water levels indicate that ground-water flow

potentials are to the west-northwest at a gradient of

approximately 008 ftft Much of the ground-water

flow occurs exclusively in the shallow bedrock

fracture system particularly In the eastern and

southern portions of the property

5 Sampling of the unconsolidated materials conducted on

behalf of Elinco demonstrated elevated TCE levels in

soil samples obtained from the rear of Building 3

Analysis of soil samples from six locations in the

vicinity of Buildings 1 and 2 have shown relatively

low levels of TCE chloroform and nethylene chloride

at and near the water table bull

6 Water quality samples indicate that volatile organic

compounds principally TCE tetrachlorethylene and

111 trichloroethane ore present in the groundwater

beneath tiie site principally to the west of Buildings

1 and 3 and to a lesser extent between Buildings 1

and 3 These compounds have been detected both in the

unconsolidated sediments and the fractured bedrock

The highest concentrations of volatile organics are

present in the bedrock aquifer in the vicinity of

Building 3

The hydrogeologic investigation wan submitted to DEP in

June of 1986 and approved in June of 1987 (see Appendix

A)

As a result of the hydrogeologic Investigation a response

action plan was prepared The plan was submitted to the

DEP Hazardous Waste Unit in April of 1987 A copy is

presented as Appendix B This plan was approved by DEP in

July of 1987 On October 21 1987 Elinco Associates the

new owner of the property entered into a consent

agreement with DEP to implement the approved response

action plan

This document is intended to serve as a ground-water

sampling and analysis plan for the Elinco Associates site

in compliance with step 1 of the October 1987 consent

agreement The scope of the plan is as follows

1 Provide background information on the geologic and

hydrogeologic setting of the facility

2 Establish and maintain precise techniques for

obtaining and preserving field samples and

bulleasurements which can be duplicated at each sairpjing

location Identified in the plan and during each

sampling period

3 Establish a schedule for sampling and analysis

4 List required preservation and shipment techniques to

ensure samples maintain their natural composition

5 Establish a chain-of-custody control for samples with

be used for each sample

7 Establish the reporting requirements for the

ground-water monitoring plan

B Geology

1 Surficial

The area In the Immediate vicinity of the Ellnco

Associates site consists predominantly of two

types of surflclal geologic deposits (Reference

3) East and south of the site at a natural

elevation of 90 feet and above the surficial

deposits consist of glacial till with scattered

bedrock outcrops Till consists of

non-stratified heterogeneous material deposited

directly by glacial Ice

To the north and west of the property the

surficial geology consists of fluvial sand and

gravel characterized as ice contact deposits

These deposits originated during the last glacial

period in an environment where glacial neltwaters

were in close proximity to the existing ice mass

This association produced formations of extreme

complexity as climatic variations changed the

depositional environment under which the formation

was created The result is a geologic deposit

which can consist of well sorted sands and gravels

to silty till-like materials to boulders The

-6shy

hydraulic conductivity of these deposits is highly

variable with ground-water preferentially

migrating along zones of greatest transmissivity

2 Bedrock

The bedrock beneath the site consists of nixed

felsic gneiss (Reference 4) It is described as

medium to coarse grained and poorly to well

foliated An outcrop napped to the east of the

site indicates a strike orientation from north to

south with an easterly dip of 20 degrees An

outcrop observed immediately to the rear of

Ibull

Building 3 showed a strike orientation generally

i trending northwest to southeast

The Fuss amp ONeill hydrogeologic investigation

demonstrated that the bedrock slopes downward to

the north and west across the site

Correspondingly the thickness of the stratified

drift deposits increases toward the northwestern

portion of the site reaching a maximum of 38 feet

at the northwestern corner Rock coring indicates

that the shallow bedrock system beneath the site

is moderately weathered within its first 6 to 12

inches In addition it is moderately to highly

fractured to depths of at least 10 feet

-7shy

C Ground-Water Hydrology

Hater level measurements conducted as part of the Fuss

t ONeill hydrogeologic Investigation have

demonstrated that ground water flows In a

west-northwest direction across the site at a gradient

of approximately 008 feet per foot In general the

water table mirrors the configuration of the bedrock

surface As previously stated extensive fracturing

of the upper bedrock Implies that the unconsolidated

deposits and the bedrock are hydraulically

interconnected This is demonstrated by the fact that

the water table is first encountered within the

unconsolidated deposits over 40 percent of the site

and is entirely within the bedrock aquifer over the bull

remainder

D Surface and Ground Water Classifications

The DEP has classified all surface and ground waters

of the State according to existing water quality and

future water quality goals The Blinco Associates

bullite is located in a class GBCA ground water area

(Reference 5) This indicates bull current

classification of GB with a goal of GA By

definition a GB area Is located In areas where

historical industrial commercial or residential

-8shy

development has or Is likely to render the ground

waters unsuitable for drinking water without

treatment (Reference 6) A GA designation

implies ground waters which nay be suitable for

public or private drinking water use without

treatment (Reference 6) The GA goal is consistent

with the nearby Kellogg-Deering Wellfield a drinking

water supply for the area

DEP has assigned a surface water classification of B

for the portion of the Norwalk River nearest to the

site (Reference 5) Because the site is removed from

the river direct impacts were not considered during

the hydrogeologlc Investigation nor are they addressed bull

III MONITORING PLAN

The ground-water monitoring plan will Initially include

quarterly bullsapling of eight monitor wells on site The

locations of these wells are shown on Plate 2 Wells K-10

and K-ll also shown were installed under the supervision

of NUS Corporation in conjunction with an Environmental

Protection Agency (EPA) Investigation of the

Kellogg-Deering Wellfield and are unavailable for

sampling Table 1 presents a summary of monitor well

completion details including depths and screen settings

As noted in the table MW-2 was destroyed during the

recent construction activity on Route 7 Space

limitations following this construction preclude

replacement of the well KW-106 located adjacent to bull

MW-105 will be monitored for water levels only The

other eight walls listed on Table 1 will be sampled under

this plan for ground-water quality

Sampling would be conducted in March June September and

December beginning in December of 1987 and continuing for

a minimum of on year At any tine after the first year

of monitoring Elinco Associates may request modifications

with respect to the frequency of data collection or the

number of wells or parameters monitored

types of surflclal geologic deposits (Reference

3) East and south of the site at a natural

elevation of 90 feet and above the surficial

deposits consist of glacial till with scattered

bedrock outcrops Till consists of

non-stratified heterogeneous material deposited

directly by glacial Ice

To the north and west of the property the

surficial geology consists of fluvial sand and

gravel characterized as ice contact deposits

These deposits originated during the last glacial

period in an environment where glacial neltwaters

were in close proximity to the existing ice mass

This association produced formations of extreme

complexity as climatic variations changed the

depositional environment under which the formation

was created The result is a geologic deposit

which can consist of well sorted sands and gravels

to silty till-like materials to boulders The

-6shy

hydraulic conductivity of these deposits is highly

variable with ground-water preferentially

migrating along zones of greatest transmissivity

2 Bedrock

The bedrock beneath the site consists of nixed

felsic gneiss (Reference 4) It is described as

medium to coarse grained and poorly to well

foliated An outcrop napped to the east of the

site indicates a strike orientation from north to

south with an easterly dip of 20 degrees An

outcrop observed immediately to the rear of

Ibull

Building 3 showed a strike orientation generally

i trending northwest to southeast

The Fuss amp ONeill hydrogeologic investigation

demonstrated that the bedrock slopes downward to

the north and west across the site

Correspondingly the thickness of the stratified

drift deposits increases toward the northwestern

portion of the site reaching a maximum of 38 feet

at the northwestern corner Rock coring indicates

that the shallow bedrock system beneath the site

is moderately weathered within its first 6 to 12

inches In addition it is moderately to highly

fractured to depths of at least 10 feet

-7shy

C Ground-Water Hydrology

Hater level measurements conducted as part of the Fuss

t ONeill hydrogeologic Investigation have

demonstrated that ground water flows In a

west-northwest direction across the site at a gradient

of approximately 008 feet per foot In general the

water table mirrors the configuration of the bedrock

surface As previously stated extensive fracturing

of the upper bedrock Implies that the unconsolidated

deposits and the bedrock are hydraulically

interconnected This is demonstrated by the fact that

the water table is first encountered within the

unconsolidated deposits over 40 percent of the site

and is entirely within the bedrock aquifer over the bull

remainder

D Surface and Ground Water Classifications

The DEP has classified all surface and ground waters

of the State according to existing water quality and

future water quality goals The Blinco Associates

bullite is located in a class GBCA ground water area

(Reference 5) This indicates bull current

classification of GB with a goal of GA By

definition a GB area Is located In areas where

historical industrial commercial or residential

-8shy

development has or Is likely to render the ground

waters unsuitable for drinking water without

treatment (Reference 6) A GA designation

implies ground waters which nay be suitable for

public or private drinking water use without

treatment (Reference 6) The GA goal is consistent

with the nearby Kellogg-Deering Wellfield a drinking

water supply for the area

DEP has assigned a surface water classification of B

for the portion of the Norwalk River nearest to the

site (Reference 5) Because the site is removed from

the river direct impacts were not considered during

the hydrogeologlc Investigation nor are they addressed bull

III MONITORING PLAN

The ground-water monitoring plan will Initially include

quarterly bullsapling of eight monitor wells on site The

locations of these wells are shown on Plate 2 Wells K-10

and K-ll also shown were installed under the supervision

of NUS Corporation in conjunction with an Environmental

Protection Agency (EPA) Investigation of the

Kellogg-Deering Wellfield and are unavailable for

sampling Table 1 presents a summary of monitor well

completion details including depths and screen settings

As noted in the table MW-2 was destroyed during the

recent construction activity on Route 7 Space

limitations following this construction preclude

replacement of the well KW-106 located adjacent to bull

MW-105 will be monitored for water levels only The

other eight walls listed on Table 1 will be sampled under

this plan for ground-water quality

Sampling would be conducted in March June September and

December beginning in December of 1987 and continuing for

a minimum of on year At any tine after the first year

of monitoring Elinco Associates may request modifications

with respect to the frequency of data collection or the

number of wells or parameters monitored

III MONITORING PLAN

The ground-water monitoring plan will Initially include

quarterly bullsapling of eight monitor wells on site The

locations of these wells are shown on Plate 2 Wells K-10

and K-ll also shown were installed under the supervision

of NUS Corporation in conjunction with an Environmental

Protection Agency (EPA) Investigation of the

Kellogg-Deering Wellfield and are unavailable for

sampling Table 1 presents a summary of monitor well

completion details including depths and screen settings

As noted in the table MW-2 was destroyed during the

recent construction activity on Route 7 Space

limitations following this construction preclude

replacement of the well KW-106 located adjacent to bull

MW-105 will be monitored for water levels only The

other eight walls listed on Table 1 will be sampled under

this plan for ground-water quality

Sampling would be conducted in March June September and

December beginning in December of 1987 and continuing for

a minimum of on year At any tine after the first year

of monitoring Elinco Associates may request modifications

with respect to the frequency of data collection or the

IV MONITOR WELL SAMPLING AND ANALYSIS METHODS

A Sample Collection

The eight wells described previously are to be

utilized to monitor ground-water levels and

ground-water quality at the Elinco Associates site

To ensure the validity of analytical results from each

well and between each sampling period a rigid

methodology for obtaining transporting and analyzing

samples will be maintained

Prior to sample collection the water level in each

well will be measured utilizing an electronic device

(M-Scope) or a steel tape accurate to within 001

feet The total depth of the well will also be bull

determined at this time so that proper evacuation

volumes can be calculated The water level measuring

device will be decontaminated between each well in an

acetonehexane solution followed by a distilled water

rinse

Aftraquor the standing volume of water in the well has

been calculated three tines this volume will be

evacuated by means of a stainless steel bailer

bullquipped with a teflon check valve Dedicated bailers

will be utilized whenever possible Should a

non-dedicated bailer be used decontamination between

-11shy

walls will consist of a non-phosphate detergent wash

followed by rinsing with tap water de-ionized water

acetone and pesticide-quality hexane in that order

The bailer will be thoroughly dried before additional

sampling is conducted Bailer cord will be dedicated

or constructed of inert Material (teflon or stainless

steel) and decontaminated as above

Two 40 01 EPA vials with teflon septums will be

collected from each monitor well Samples will be

placed on ice and transported to a state-approved

laboratory for halogenated volatile organic analysis

B Sample Identification bull

A field data sheet IB to be used for each sampling

quarter A copy is presented as Appendix D This

bullheet will serve to maintain adequate records for each

bullample collected at the site

C QAQC Program

As part of the sampling program procedures will be

conducted to insure the reliability and validity of

field and laboratory data Trip blanks of each type

of sample bottle will be prepared in the laboratory

-12shy

using deionlzed water and shall be transported to the

site handled like A sample returned to the

laboratory and analyzed for the appropriate

parameters One set of trip blanks per sampling event

will be prepared

Whenever non-dedicated bailers are used an equipment

blank will be prepared in the field by filling the

bailer with distilled water and subsequently obtaining

a sample in the appropriate sample containers This

procedure will be conducted following equipment

cleaning at the last well to be sampled on each day of

field operations Samples will be analyzed according

to the previously described techniques e

D Analytical Procedures

Sample analysis will be performed only at laboratories

certified by the State of Connecticut Procedures

utilized shall be in accordance with all EPA standards

as detailed by EPA Manual SW-B46 Each laboratory

Dear Mr Parker

As per our meeting of April 16 1987 please find enclosed a copy of our report entitled Hydrogeologic Investigation -Bardaniae Buildings - 272 Main Avenue - Norwalk Connecticut dated June 1986 As Indicated in the cover letter this report has been previously submitted to the Water Compliance Unit in response to a consent agreement

Through this letter we would also like to formalize our proposal for remedial action at the site The objectives of the system proposed would be as follows

1 Prevent off-site migration of contaminants by creating a localized ground-water depression sufficient to encompass the entire western property boundary

2 Remove contaminated ground vator from both the stratified drift and bedrock aquifers

3 Treat the ground water to remove contaminants to levels which will allow the water to be discharged to the local storm sewer system

The basic components of the remediation system as shown on the attached plates would consist of two 100 foot deep 6 inch bedrock wells one on the west side of Building 1 and one on the west side of Building 3 and a single air stripper which would treat the Influent from both wells Treated water would be shydischarged to the storm sewer along Main Avenue

Although there in the possibility that activated carbon treatment prior to effluent discharge may be necessary for a short tine during the early stages of the operation we believe that this event is highly unlikely Based on our calculations no carbon treatment should be necessary to control air emissions of volatile compounds front the air stripping equipment

To implement the remedial program described we anticipate that the following work plan would be required

1 Construct two interceptor wells

2 Install pumping equipment designed in accordance with approximate yield data determined during well construction

3 Install temporary air stripper for pilot treatment system testing

4 Obtain discharge permit for test effluent

5 Conduct 72 hour pumping test on both wells to determine area of influence and probable capture zone

6 Conduct water quality testing of influent and effluent from the air stripper during pump testing

7 Design permanent pumping and treatment aystern piping electronics and treatment building to house controls and the air stripper unit

RE Remedial Action Plan Elinco Associates 272 Main Avenue Norwalk Connecticut

Dear Mr Parker

As per our meeting of April 16 1987 please find enclosed a copy of our report entitled Hydrogeologic Investigation -Bardaniae Buildings - 272 Main Avenue - Norwalk Connecticut dated June 1986 As Indicated in the cover letter this report has been previously submitted to the Water Compliance Unit in response to a consent agreement

Through this letter we would also like to formalize our proposal for remedial action at the site The objectives of the system proposed would be as follows

1 Prevent off-site migration of contaminants by creating a localized ground-water depression sufficient to encompass the entire western property boundary

2 Remove contaminated ground vator from both the stratified drift and bedrock aquifers

3 Treat the ground water to remove contaminants to levels which will allow the water to be discharged to the local storm sewer system

The basic components of the remediation system as shown on the attached plates would consist of two 100 foot deep 6 inch bedrock wells one on the west side of Building 1 and one on the west side of Building 3 and a single air stripper which would treat the Influent from both wells Treated water would be shydischarged to the storm sewer along Main Avenue

Although there in the possibility that activated carbon treatment prior to effluent discharge may be necessary for a short tine during the early stages of the operation we believe that this event is highly unlikely Based on our calculations no carbon treatment should be necessary to control air emissions of volatile compounds front the air stripping equipment

To implement the remedial program described we anticipate that the following work plan would be required

1 Construct two interceptor wells

2 Install pumping equipment designed in accordance with approximate yield data determined during well construction

3 Install temporary air stripper for pilot treatment system testing

4 Obtain discharge permit for test effluent

5 Conduct 72 hour pumping test on both wells to determine area of influence and probable capture zone

6 Conduct water quality testing of influent and effluent from the air stripper during pump testing

7 Design permanent pumping and treatment aystern piping electronics and treatment building to house controls and the air stripper unit

8 Construct and Install above i

9 Obtain appropriate state and local permits as necessary

10 Activate the system and monitor its Initial operation to determine treatment efficiency and capture zone Monthly sampling of affluent will be required

RE Remedial Action Plan Elinco Associates 272 Main Avenue Norwalk Connecticut

Dear Mr Parker

As per our meeting of April 16 1987 please find enclosed a copy of our report entitled Hydrogeologic Investigation -Bardaniae Buildings - 272 Main Avenue - Norwalk Connecticut dated June 1986 As Indicated in the cover letter this report has been previously submitted to the Water Compliance Unit in response to a consent agreement

Through this letter we would also like to formalize our proposal for remedial action at the site The objectives of the system proposed would be as follows

1 Prevent off-site migration of contaminants by creating a localized ground-water depression sufficient to encompass the entire western property boundary

2 Remove contaminated ground vator from both the stratified drift and bedrock aquifers

3 Treat the ground water to remove contaminants to levels which will allow the water to be discharged to the local storm sewer system

The basic components of the remediation system as shown on the attached plates would consist of two 100 foot deep 6 inch bedrock wells one on the west side of Building 1 and one on the west side of Building 3 and a single air stripper which would treat the Influent from both wells Treated water would be shydischarged to the storm sewer along Main Avenue

Although there in the possibility that activated carbon treatment prior to effluent discharge may be necessary for a short tine during the early stages of the operation we believe that this event is highly unlikely Based on our calculations no carbon treatment should be necessary to control air emissions of volatile compounds front the air stripping equipment

To implement the remedial program described we anticipate that the following work plan would be required

1 Construct two interceptor wells

2 Install pumping equipment designed in accordance with approximate yield data determined during well construction

3 Install temporary air stripper for pilot treatment system testing

4 Obtain discharge permit for test effluent

5 Conduct 72 hour pumping test on both wells to determine area of influence and probable capture zone

6 Conduct water quality testing of influent and effluent from the air stripper during pump testing

7 Design permanent pumping and treatment aystern piping electronics and treatment building to house controls and the air stripper unit

8 Construct and Install above i

9 Obtain appropriate state and local permits as necessary

10 Activate the system and monitor its Initial operation to determine treatment efficiency and capture zone Monthly sampling of affluent will be required
