Subject: Addendum No. 1 – Revised Groundwater Quality Trend Monitoring Work Plan

Westside Water Quality Coalition

Western Tulare Lake Basin, California

Dear Mr. Hughes:

Wood Environment & Infrastructure Solutions, Inc. (Wood), has prepared this Addendum No. 1 -Revised

Groundwater Quality Trend Monitoring Work Plan on behalf of Klein, DeNatale, Goldner, LLP, and your

client, the Westside Water Quality Coalition (Coalition). The Coalition is acting as a Third-Party Coalition

pursuant to Waste Discharge Requirements General Order R5-2013-0120 (General Order) issued by the

California Regional Water Quality Control Board (RWQCB) in September 2013. The Coalition entered into

a Memorandum of Understanding with the Central Valley Groundwater Monitoring Collaborative on

October 31, 2017, and is currently a participating member.

Introduction:

This addendum is in response to the RWQCB letter dated June 29, 2018, Review of the Westside Water

Quality Coalition Revised Groundwater Quality Trend Monitoring Work Plan. The letter requested that the

Coalition include the following information:

1. A rational for the sufficiency of the number of proposed wells to provide adequate coverage in

the Coalition’s Area;

2. A list of the proposed trend monitoring wells that you have permission to sample, and that have

been field verified;

3. Well construction details (e.g., depth, screen interval, well seal information, etc.) for all trend

monitoring wells;

4. An additional trend monitoring well to replace Starrh 9K No.2 well; and

5. Trend monitoring well(s) to monitor groundwater in T28S R21E, MDB&M

Revised Groundwater Quality Trend Monitoring Program

The Revised Groundwater Quality Trend Monitoring Program (GWQTMP) work plan originally designated

20 wells for the GWQTMP network (13 unconfined and 7 perched zone wells). The Coalition has

subsequently revised their GWQTMP well network based on the comments provided by the RWQCB and

due to the result of the Coalitions field vetting process of the original 20 proposed wells previously

selected for groundwater monitoring.

Coalition personnel conducted field verification for wells and contacted well owner/operators to inquire

about well construction information and to secure site access and permission to sample individual wells.

Wood also obtained well construction records from the California Department of Water Resources (DWR)

Well Completion Report Map Application (https://dwr.maps.arcgis.com/apps/webappviewer/

index.html?id=181078580a214c0986e2da28f8623b37) for each Township, Range, and Section located

within the Coalition boundary. The vetting process found that nine of the originally proposed unconfined

groundwater wells could not be field located, were former test wells that had been subsequently

destroyed, or consisted of wells with little or no well construction information or no associated DWR

record. These wells are shown on Figure 1 in red symbology.

Ten alternative wells were identified as suitable replacements based on well construction and/or proximity

to irrigated agricultural lands. Two of these wells are currently being installed by the United States

Geologic Survey (USGS); the USGS Lost Hills Well and USGS BWSD Well#5. Complete well construction

information for these wells is not currently available, but will be transmitted to the RWQCB when the wells

are completed. USGS has indicated to the Coalition that the wells will be available for groundwater

sampling during the fall 2018 GWQTMP monitoring event. The Coalition intends to sample the within the

cluster completed in first encountered groundwater.

The revised GWQTMP well network now consists of 21 monitoring wells. Thirteen of these wells are

screened in unconfined groundwater wells (Figure 1, in green symbology) and 8 wells are screened in

perched groundwater (Figure 1, in orange symbology). Table 1 contains available well construction

information provided by the well owner or contained in DWR records. Well construction records are

provided in Attachment A.

Two GWQTMP wells, Berrenda Mesa #1 and Berrenda Mesa #3 do not have available well construction

documentation from DWR records. The owner of Berrenda Mesa #1 has provided the Coalition with verbal

information regarding the wells perforated interval (Table 1) and the Coalition is performing research to

attempt to locate well construction information for Berrenda Mesa #3 well.

The RWQCB requested that a replacement to Starrh 9K No. 2 well be added to the GWQTMP network.

There is no adequate replacement well for Star2K No. 2 on irrigated land south of the location of Aera

Energy LLC (Aera), Belridge well 5B2 in T29SR22E Sections 07, 08, 09, or 18. All wells in these sections have

screened intervals located either across or below the E-Clay aquitard. There are shallow wells at the Clean

Harbors facility in Section 16; however, these wells are not downgradient of any irrigated agriculture.

There are also shallow wells that monitor the Cymric produced water impoundments, but they are also

not located downgradient of irrigated lands. We are proposing to use only Aera Belridge well 5B2 to

monitor irrigated lands in T29SR22E; this well is located directly downgradient of irrigated lands.

July 31, 2018

The RWQCB requested that one or more wells be located in T28SR21E even though shallow monitoring

wells in this section are impacted by nitrogen sourced from former impoundments not associated with

irrigated agriculture. The Coalition proposes to use a new USGS well BWSD #5 in Section 8 of T28SR21E

and monitoring well Aera Belridge 13A1 located in Section 13. In addition, the Coalition plans to add a

perched zone well in Section 8 of T28SR22E situated east of irrigated land. These wells will provide

adequate coverage of first encountered groundwater in this Township/Range downgradient of irrigated

agriculture.

Rational and Adequacy of the GWQTMP Monitoring Network

The rationale for the location and number of wells is based on a general continuity in crop types, primarily

almond and pistachio, in which similar farming practices are applied within the Coalition. The general

continuity in crop types and farming practice favors a groundwater monitoring network of fewer wells

because the variability expected in application of irrigation, fertilizers, and soil amendments is low.

Furthermore, the water quality within the Coalition is generally poor in most areas occupied by irrigated

lands with some areas having total dissolved solids concentrations greater than 3,000 in the perched and

unconfined/semi-confined aquifers. There are also no communities that use groundwater for municipal

water supply downgradient of irrigated lands. These communities use imported treated surface water or

groundwater.

The revised GWQTMP network consisting of 21 monitoring wells. Thirteen wells are located in the upper

unconfined aquifer with a density of about one well per Township/Range where irrigated agriculture is

present. Two additional wells were added in Township 28S Range 21East to complete coverage of

irrigated agriculture in this area. Eight wells are located in the perched aquifer at a spacing of about one

or two wells per Township/Range. The coverage of the perched aquifer in the A-zone aquifer is more

complete with the addition of an eighth well. Nineteen wells have established well construction data. Only

two wells have incomplete information and the Coalition is still researching as to whether well

construction information is available.

There are no existing monitoring or water supply wells in the Dudley Ridge area, the two former GWQTMP

wells were found to no longer exist during field verification. Groundwater flow in the Dudley Ridge areas

is toward the adjacent Tulare Lake Sub-Basin which has been delisted for Municipal and Agricultural

beneficial use above the E-Clay aquitard due to the presence of poor water quality. Furthermore, there are

no plan to develop water resources in Dudely Ridge area due to poor water quality. Acknowledging these

facts, the Coalition does not propose to monitor impacts of irrigated agriculture in this area since any

negative impact will not affect any current or future beneficial use in the downgradient designated area.
