1.0 INTRODUCTION

The Saco River runs between the towns of Biddeford and Saco entering into Saco Bay

approximately 12 miles southwest of Portland, ME. The existing Federal Navigation

Project (FNP) in the Saco River consists of an 8 foot (Mean Lower Low Water - MLLW)

channel extending upstream approximately 6 miles from Saco Bay to a 6 foot (MLLW)

maneuvering basin at Factory Island. Three 6 foot (MLLW) anchorage areas near the

mouth of the river provide a total of 13.5 acres of anchorage for a small fleet of

recreational and commercial fishing vessels.

The Saco River was last dredged by the New England District (NAE) of the US Army

Corps of Engineers (USACE) in 1994 when approximately 46,378 cubic yards (cy) of

sand was hydraulically dredged from downstream portions of the channel and anchorages

and placed on nearby Camp Ellis beach. Prior to that, in 1992, approximately 15,785

cubic yards (cy) of sand and woody organic debris was hydraulically dredged from the

channel and maneuvering basin in the vicinity of Factory Island and placed into naturally

deep areas of the river located approximately 4,000 feet downstream of the dredge area.

NAE is currently proposing to dredge approximately 128,219 cy of sandy material from

shoaled areas totaling 77 acres within the channel, maneuvering basin, and anchorages of

the Saco River FNP to restore the project to its authorized dimensions. It is expected that

these areas will be hydraulically dredged. Suitable sandy material would be disposed of

on or adjacent to Camp Ellis and Hills beaches. Any fine grained material would be

disposed of at the Saco Bay Disposal Site (SBDS).

The purpose of the sampling effort described in this report was to collect sediment cores

from 17 locations within the proposed dredge area in order to evaluate suitable disposal

options. The sampling effort was conducted in accordance with the sampling and analysis

plan (Appendix A) dated May 15, 2014 that was developed by the Environmental

Resources Section (ERS) of NAE, and coordinated with the State of Maine Department

of Environmental Protection (MEDEP, the United States Fish and Wildlife Service

(USFWS), and the United States Environmental Protection Agency (EPA) Region 1. This

report describes the field methods employed, site conditions encountered, and results of

physical analysis.

2.0 MATERIALS AND METHODS

Sediment sampling efforts were conducted on July 17 and 18 of 2014. Work was carried

out onboard the R/V Gloria H., a 24 foot pontoon style workboat outfitted with an a-

frame and electric winch for sampling through a moon pool located in the center of the

vessel. A three point anchor system was used to hold the boat in position while sampling.

Positioning was achieved using a WAAS enabled Lowrance HDS-10 sonar/chart plotter

with external LGC-4000 GPS receiver antenna, and verified with a Trimble GeoXM

Differential Global Positioning System (DGPS), both with an accuracy of 3 meters or

less. Depth measurements were made using the HDS-10 unit and 50/200 kHz transducer

with lead line verification. Tidal corrections to Mean Lower Low Water (MLLW) were

2

made using data for the Wood Island Harbor tide station, accessed in the field through the

tides and currents feature of Navionics Mobile software.

2.1 Sample Collections

Sediment samples were collected to project depth (authorized depth plus one foot of

overdepth) or refusal from all 17 stations (Figures 1 & 2) using a Navco pneumatic

vibracorer and 2.75” i.d. polycarbonate tubing. Upon collection the cores were secured in

an upright position and allowed to settle before being processed on board the sampling

vessel. Sampling equipment was cleaned with a brush and alconox solution then rinsed

with site water prior to sampling and between each sample station. The core liners were

assumed to be clean as-received from the supplier but were rinsed in site water prior to

use.

Water depths in the vicinity of the sample locations ranged from 0.6 to 6.5 feet MLLW.

The sediment cores from all stations consisted of tan to gray poorly graded medium to

fine sand. Most of the stations inside of the breakwaters at the mouth of the channel had a

thin layer of 1-2 inch long wood chips at the surface. The vibracorer reached refusal in

hard packed sand before reaching the project depth at station J. Refusal was met in or

slightly below the target overdepth range at the remainder of the stations.

Sediment collection data is summarized in Table 1. Sampling logs are presented in

Appendix B.

2.2 Sample Processing

Upon collection the sediment cores from each station were secured in an upright position

and allowed to settle. After settling, the cores were measured, and clear excess water was

carefully drained from the top of the core tube by drilling a small hole in the liner above

the water/sediment interface. Measured cores were placed horizontally into a wooden

trough and secured by hand. Each core liner was cut lengthwise using electric shears in

two places, approximately 180° apart, and clean stainless steel wire was then used to slice

the length of the core into two halves. Immediately after a core was split and exposed to

the atmosphere, it was photographed, described, and transferred into a clean stainless

steel pan for sampling.

Each split core was photographed before undergoing the description process. All core

photos included a stadia rod for scale, and for referencing the depth below surface. A

photograph of the complete core was taken, as well as close-ups of discrete layering

down core, and sediment strata horizons/transitions of interest.

Cores were examined from the top of the core, downward to the bottom, using a stadia

rod to define sediment layer thicknesses and depth below the surface (top of core at

sediment–water interface). Each core was classified in accordance with ASTM D 2488,

Standard Practice for Description and Identification of Soils (Visual-Manual Procedure),

and notes on relative grain sizes, color, odor, strata, and other pertinent observations were

recorded in the environmental sampling logs (Appendix B).

The material from each core was transferred into a clean stainless steel pan and

homogenized using clean stainless steel spatulas and spoons. Representative portions

from each sample were placed into clean zip-loc bags for grain physical testing and

archiving. All samples were maintained in coolers on ice for the duration of sampling

activities and delivered to Alpha Analytical Laboratory in Mansfield, MA upon

conclusion of the field sampling effort. The Chain of Custody forms are presented in

Appendix C.

2.3 Physical Testing

Grain size and total solids/ water content analysis of 16 samples was completed

by Alpha Analytical Laboratory in Mansfield, MA. The sample collected from station O

was analyzed by the NAE environmental laboratory in Concord, MA because it was not

included in the delivery to Alpha Analytical. A complete list of parameters and target

detection limits is provided in Table 2. There were no deviations from the established

laboratory testing protocols.

CENAE–EP-V 15 May 2014

MEMORANDUM FOR: Craig Martin, Project Manager, CENAE-PP-P-N

SUBJECT: Sampling and Analysis Plan for the Saco River Federal Navigation Project, Saco and Biddeford, Maine.

1. Background: The New England District (NAE) of the US Army Corps of

Engineers (USACE) is proposing to hydraulically dredge approximately 128,219 cu. yds. of sandy material from shoaled areas totaling 77 acres within

the 8 foot channel and 6 foot anchorages (MLLW) of the Saco River Federal Navigation Project in Saco and Biddeford, Maine. These areas will be dredged to the authorized project depth plus 1 foot of allowable overdepth. Suitable sandy

material would be disposed of on or adjacent to Camp Ellis and Hills beaches. Any fine grained material would be disposed of at the Saco Bay Disposal Site

(SBDS).

The purpose of the sampling and analysis plan described below is to

gather information to support a suitability determination for the proposed disposal options. This sampling and analysis effort will consist of collection of dredge site sediment for grain size and bulk sediment chemistry. The results of

grain size analysis may be used to exclude the proposed dredge material from further analysis. If the dredge site sediment does require chemical analysis

then sediment from the SBDS will be collected and analyzed as a basis for comparison.

2. Methodology: All sampling and analysis activities shall follow the requirements set forth in the “Regional Implementation Manual for the Evaluation of Dredged Material Proposed for Disposal in New England Waters"

(RIM) dated May 6, 2004. All laboratories used for this project must have an approved Laboratory Quality Assurance Plan (LQAP) on file with NAE. Any data

produced from a lab without an approved LQAP will not be accepted. The RIM, a list of laboratories with approved LQAPs, and the reporting format and requirements for electronic submission of data are available for download

through the NAE website:

http://www.nae.usace.army.mil/Missions/Regulatory/DredgedMaterialProgram/RegionalImplementationManual.aspx

3. Known Sources of Contamination: There have been no recent spills in the project area. Waste water treatment plants in the towns of Saco and Biddeford are located on either side of the upstream channel and anchorage

area. There is one storm waterfall at the end of Edgewater Lane and one combined outfall at the end of Front Street, both in the town of Saco.



CENAE-EP-V

SUBJECT: Sampling Plan for the Saco River Federal Navigation Project, Saco and Biddeford, Maine.

4. Sample Collection: In the first phase of testing, sediment cores shall be

taken from the areas to be dredged at the seventeen locations specified in Table 1 (also see Figures 1-2). Core samples shall be taken to the proposed dredge depth plus the overdredge amount. The cores shall be inspected in the

field for stratification. If the cores show significant stratification, in the opinion of the sampling crew, subsamples shall be made of each layer. Sufficient material shall be collected for grain size and bulk sediment chemistry analyses

as described in the sections below.

All sediment and water being held for testing shall be stored in accordance with the requirements in Table 2 (from Table 8-2 in Evaluation of Dredged Material Proposed for Ocean Disposal, Testing Manual, 1991).

5. Positioning: The latitude and longitude for each sample location shall be reported in the Geographic NAD 83 coordinate system in degree decimal

minute format. The horizontal accuracy of each sample location shall be 3 meters or less. The horizontal accuracy at each sample location shall be

reported along with the coordinates. 6. Grain Size: Each core or core layer from the dredge site shall be

individually analyzed for grain size and the results reported to the Environmental Resources Section (ERS) project technical manager or Marine

Analysis Section (MAS) project manager, before any compositing is performed. The final compositing plan will be determined based on proximity, sediment type, and physical characteristics.

7. Sediment Chemistry: Bulk sediment chemistry shall be performed on the individual or composite sediment samples from the dredge area according

to the final compositing plan. Testing parameters, analytical methods, and reporting limits to be used are outlined in Table 2 (Extracted from Tables 1, 2,

and 3 of the RIM). The listed analytical methods are recommended but can be replaced by other methods that will give the required reporting limits. The Total Organic Carbon analysis (TOC) shall be performed in duplicate on each

composited sample and a TOC Standard Reference Material (SRM) shall be run with the sample batch. Additional guidance on the physical and chemical

analysis of sediments can be found in chapter 5 of the RIM. 8. Reporting: All sediment testing data is required to be submitted

electronically in the electronic data deliverable (EDD) format available on the RIM website. Hard copy data submission is also required but may be substituted with a printer friendly, easy-to-read format (e.g., PDF, MS Word).

Any analytes not detected shall be reported as the reporting limit and qualified with a “U”. Non-detects shall not be reported as the method detection limit

CENAE-EP-V


(MDL). RIM quality control summary tables are required to be submitted with each project dataset. These tables are found in Appendix II of the RIM and are

available on the RIM website 9. Any questions should be directed to Richard Loyd (978-318-8048) or

Case Narrative

The samples were received in accordance with the Chain of Custody and no significant deviations were encountered during the preparation

or analysis unless otherwise noted. Sample Receipt, Container Information, and the Chain of Custody are located at the back of the report.

Results contained within this report relate only to the samples submitted under this Alpha Lab Number and meet all of the requirements of

NELAC, for all NELAC accredited parameters. The data presented in this report is organized by parameter (i.e. VOC, SVOC, etc.). Sample

specific Quality Control data (i.e. Surrogate Spike Recovery) is reported at the end of the target analyte list for each individual sample,

followed by the Laboratory Batch Quality Control at the end of each parameter. If a sample was re-analyzed or re-extracted due to a

required quality control corrective action and if both sets of data are reported, the Laboratory ID of the re-analysis or re-extraction is

designated with an "R" or "RE", respectively. When multiple Batch Quality Control elements are reported (e.g. more than one LCS), the

associated samples for each element are noted in the grey shaded header line of each data table. Any Laboratory Batch, Sample Specific %

recovery or RPD value that is outside the listed Acceptance Criteria is bolded in the report. Performance criteria for CAM and RCP methods

allow for some LCS compound failures to occur and still be within method compliance. In these instances, the specific failures are not

narrated but are noted in the associated QC table. This information is also incorporated in the Data Usability format for our Data Merger tool

where it can be reviewed along with any associated usability implications. Soil/sediments, solids and tissues are reported on a dry weight

basis unless otherwise noted. Definitions of all data qualifiers and acronyms used in this report are provided in the Glossary located at the

back of the report.

In reference to questions H (CAM) or 4 (RCP) when "NO" is checked, the performance criteria for CAM and RCP methods allow for some

quality control failures to occur and still be within method compliance. In these instances the specific failure is not narrated but noted in the

associated QC table. The information is also incorporated in the Data Usability format of our Data Merger tool where it can be reviewed

along with any associated usability implications.

Please see the associated ADEx data file for a comparison of laboratory reporting limits that were achieved with the regulatory Numerical

Standards requested on the Chain of Custody.

HOLD POLICY

For samples submitted on hold, Alpha's policy is to hold samples (with the exception of Air canisters) free of charge for 21 calendar days

from the date the project is completed. After 21 calendar days, we will dispose of all samples submitted including those put on hold unless

you have contacted your Client Service Representative and made arrangements for Alpha to continue to hold the samples. Air canisters will

be disposed after 3 business days from the date the project is completed.

Please contact Client Services at 800-624-9220 with any questions.

Sample Receipt

Sample "O" was not received. Authorization to proceed with all other samples was given per the client on June

21, 2014.

Grain Size

The WG709958-1 Laboratory Duplicate RPD, performed on L1416145-14, is outside the acceptance criteria

for Fines (26%). The elevated RPD has been attributed to the non-homogeneous nature of the sample utilized

for the laboratory duplicate.

The WG709958-1 Laboratory Duplicate RPD, performed on L1416145-14, is above the acceptance criteria for

% Coarse Sand (29%); however, the sample and duplicate results are less than five times the reporting limit.

Therefore, the RPD is valid.

I, the undersigned, attest under the pains and penalties of perjury that, to the best of my knowledge and belief and based upon my personal inquiry of those responsible for providing the information contained in this analytical report, such information is accurate and complete. This certificate of analysis is not complete unless this page accompanies any and all pages of this report.

Estimated Detection Limit: This value represents the level to which target analyte concentrations are reported as estimated values, when those target analyte concentrations are quantified below the reporting limit (RL). The EDL includes any adjustments from dilutions, concentrations or moisture content, where applicable. The use of EDLs is specific to the analysis of PAHs using Solid-Phase Microextraction (SPME).Environmental Protection Agency.

Laboratory Control Sample: A sample matrix, free from the analytes of interest, spiked with verified known amounts of analytes or a material containing known and verified amounts of analytes.Laboratory Control Sample Duplicate: Refer to LCS.

Laboratory Fortified Blank: A sample matrix, free from the analytes of interest, spiked with verified known amounts of analytes or a material containing known and verified amounts of analytes.Method Detection Limit: This value represents the level to which target analyte concentrations are reported as estimated values, when those target analyte concentrations are quantified below the reporting limit (RL). The MDL includes any adjustments from dilutions, concentrations or moisture content, where applicable.Matrix Spike Sample: A sample prepared by adding a known mass of target analyte to a specified amount of matrix sample for which an independent estimate of target analyte concentration is available. Matrix Spike Sample Duplicate: Refer to MS.

Not Applicable.

Not Calculated: Term is utilized when one or more of the results utilized in the calculation are non-detect at the parameter's reporting unit.Not Ignitable.

Reporting Limit: The value at which an instrument can accurately measure an analyte at a specific concentration. The RL includes any adjustments from dilutions, concentrations or moisture content, where applicable.Relative Percent Difference: The results from matrix and/or matrix spike duplicates are primarily designed to assess the precisionof analytical results in a given matrix and are expressed as relative percent difference (RPD). Values which are less than five times the reporting limit for any individual parameter are evaluated by utilizing the absolute difference between the values; although the RPD value will be provided in the report.Standard Reference Material: A reference sample of a known or certified value that is of the same or similar matrix as the associated field samples.

Spectra identified as "Aldol Condensation Product".

The analyte was detected above the reporting limit in the associated method blank. Flag only applies to associated field samples that have detectable concentrations of the analyte at less than ten times (10x) the concentration found in the blank. For MCP-related projects, flag only applies to associated field samples that have detectable concentrations of the analyte at less than ten times (10x) the concentration found in the blank. For DOD-related projects, flag only applies to associated field samples that have detectable concentrations of the analyte at less than ten times (10x) the concentration found in the blank AND the analyte was detected above one-half the reporting limit (or above the reporting limit for common lab contaminants) in the associated method blank. For NJ-Air-related projects, flag only applies to associated field samples that have detectable concentrations of the analyte above the reporting limit.Co-elution: The target analyte co-elutes with a known lab standard (i.e. surrogate, internal standards, etc.) for co-extracted analyses.Concentration of analyte was quantified from diluted analysis. Flag only applies to field samples that have detectable concentrations of the analyte.Concentration of analyte exceeds the range of the calibration curve and/or linear range of the instrument.

The concentration may be biased high due to matrix interferences (i.e, co-elution) with non-target compound(s). The result should be considered estimated.

1 The reference for this analyte should be considered modified since this analyte is absent from the target analyte list of the originalmethod.
