RFB NO. 24-25-63
Replacement of Two (2) Groundwater Monitoring Wells
Visalia Public Works Department

imposed by the U.S. government in response to Russia’s actions in Ukraine, as well as any sanctions imposed under state law. The EO directs state agencies to terminate contracts with, and to refrain from entering any new contracts with, individuals or entities that are determined to be a target of Economic Sanctions.

Accordingly, should the State determine Contractor is a target of Economic Sanctions or is conducting prohibited transactions with sanctioned individuals or entities, that shall be grounds for termination of this agreement. The State shall provide Contractor advance written notice of such termination, allowing Contractor at least 30 calendar days to provide a written response.

THE PARTIES HAVE

DETERMINED AND AGREED THAT THE ACTUAL AMOUNT OF DAMAGES THAT WOULD BE SUFFERED BY CITY AS A RESULT OF ANY SUCH DELAY IS THE SUM OF TWO HUNDRED DOLLARS ($200.00) PER DAY, WHICH IS A REASONABLE ESTIMATE OF THE AMOUNT OF SUCH DAMAGES. THE PAYMENT OF SUCH

AMOUNT AS LIQUIDATED DAMAGES IS NOT INTENDED AS A FORFEITURE OR PENALTY WITHIN THE MEANING OF CALIFORNIA CIVIL CODE SECTIONS 3275 OR 3369, BUT IS INTENDED TO CONSTITUTE LIQUIDATED DAMAGES TO CITY PURSUANT TO CALIFORNIA CIVIL CODE SECTIONS 1671, 1676 AND 1677. CITY HEREBY WAIVES THE PROVISIONS OF CALIFORNIA CIVIL CODE SECTION 3389. CITY

AGREES THAT THESE LIQUIDATED DAMAGES SHALL BE IN LIEU OF ANY OTHER MONETARY RELIEF

OR OTHER REMEDY FOR DELAY, INCLUDING, WITHOUT LIMITATION, SPECIFIC PERFORMANCE, TO

WHICH CITY MIGHT OTHERWISE BE ENTITLED UNDER THIS AGREEMENT, AT LAW OR IN EQUITY, AND SHALL BE CITY’s SOLE AND EXCLUSIVE RIGHT AND REMEDY, EXCEPT THAT CITY MAY TERMINATE THE AGREEMENT.

WORKPLAN FOR REPLACEMENT MONITOR WELLS AT

CITY OF VISALIA RECLAMATION FACILITY

INTRODUCTION
The City of Visalia WRF is located west of Highway 99 and south of Highway 198. There are 13 WRF monitor wells that are not dry.

Seven wells less than about 160 feet deep tap the upper aquifer. Six of these wells were drilled in 2014 and produce adequate water for sampling. W-Hl and MW-M range in depth from 104 to 109 feet and have been dry since 2019. They were considered downgradient wells. Figure 1 shows the locations of these monitor wells and Table 1 provides construction data for them. This workplan is for replacement wells for MW-Hl and MW-M.

LOCAL HYDROGEOLOGIC CONDITIONS
An upper aquifer is present above a depth of about 270 feet. A confining bed (the Corcoran Clay) is present from about 270 to 290 feet in depth. The lower aquifer is present below the confining bed and above a depth of about 500 feet. Figure 2 is a water-level elevation map for the upper aquifer for October 25, 2024. Water-level elevations ranged from 174.3 feet above mean sea level at MW-0 to the northeast to 148.9 feet at MW-S to the southwest. A groundwater mound was indicated beneath and downgradient of the ponds, in the vicinity of MW-0 and MW-R. Away from this mound, the direction of 346

groundwater flow in the upper aquifer was to the southwest or west.

Water-level records for the upper aquifer wells that have not gone dry indicate fairly stable levels (Moore Twining Associates, Inc. 2025, graph 1).

PROPOSED REPLACEMENT MONITOR WELLS
Water levels in the upper aquifer wells that aren't dry have ranged from about 90 to 135 feet deep. The deepest water levels have been at MW-N (the most easterly well) and the shallowest at MW-P and MW-Q (the most westerly wells).

DRILLING DETAILS
5 The holes for the new monitor wells would be drilled by the direct rotary method to 160 feet in depth and electric logged. The electric logging would be done by Pacific Surveys or Boredata. Drill cuttings for the monitor wells would be logged by a geologist under the direct supervision of Cheryl Lassotovitch, a Registered Geologist and Certified Hydrogeologist in California. A geologic log would be prepared for each well, including the Unified Soil Classification designations.

feet in depth. This perforated interval may be slightly modified in the field based on interpretation of the electric logs. The proposed perforated intervals should allow monitoring for decades into the future. 12-inch diameter holes would be drilled and 4-inch diameter Schedule 40 PVC casings installed. The casing joints would be screwed together. A slot size of 0.03 inch would be used and the gravel gradation would be 6 x 20. Each well would be gravel packed up to a depth of five feet above the top of the perforations. Five feet of bentonite would then be placed on top of the gravel pack. A pressure grouted cement seal would then be placed from the top of the bentonite to the land surface. The top of the wells would be vaulted and a manhole cover placed at the land surface above the top of the casing.

WELL DEVELOPMENT
After the cement seals have set for at least 24 hours, each well would be developed by airlifting or bailing for at least two hours, and subsequently by pumping and surging for at least two more hours.

A steel conductor casing with a pump base and steel bollards would then be installed.

PUMP INSTALLATION
A normal two and a-half-inch diameter submersible pump would be 7 352
installed in each replacement monitor well, along with a PVC access tube to allow water-level measurements with an electric sounder. The pump intakes would be placed to a depth of about five feet above the bottoms of each of the wells.

WELL SURVEY
A Californian licensed surveyor would survey the wells. The elevation of the top of the PVC casings would be surveyed to within 0.01 foot and the location precisely surveyed. The same elevation datum would be used as for the existing monitor wells.

SCHEDULE
Once approval for the proposed work is obtained, the new monitor wells would be installed, developed, and the initial monitoring conducted within three months of approval. The monitor well completion reports would be submitted within two months after the wells are first sampled.

2024 SECOND SEMIANNUAL GROUNDWATER MONITORING REPORT

CITY OF VISALIA WATER RECLAMATION FACILITY

VISALIA, CALIFORNIA

1.0 INTRODUCTION
This report summarizes field activities and analytical results associated with the 2024 second semiannual groundwater monitoring event at the City of Visalia Water Reclamation Facility (VWRF). (The site was previously known as Visalia Water Conservation Plant). The VWRF is operated by the City of Visalia and is located at 7579 Avenue 288, Visalia, California.

Groundwater monitoring was conducted per California Regional Water Quality Control Board (CRWQCB) Waste Discharge Requirements (WDR) No. R5-2018-0046.

This report includes a description of the monitoring well network, a summary of groundwater monitoring activities, and the analytical results from the groundwater monitoring event.

Monitoring well locations and wastewater discharge areas are depicted in Drawing 1.

2.0 GEOLOGY
Based on Boyajian & Ross, Inc. report titled “Groundwater Investigation Report” dated January 30, 1998, the stratigraphy beneath the VWRF can be divided into four predominant zones to depths of 465 feet below surface grade (BSG), the maximum depth explored. These stratigraphic units appear to dip gently to the southwest at approximately 20 feet per mile. The uppermost stratigraphic zone is comprised of interbedded, predominantly coarse-grained sediments to approximately 100 feet BSG. The next zone consists of relatively thin beds of sand interbedded with clay, clayey silt, and silt. This interbedded zone is approximately 160 to 170 feet thick and occurs to about 270 feet BSG. The uppermost coarse-grained zone and the underlying thin bedded sand and silt zone comprise the “upper aquifer”.

The third stratigraphic zone is a very stiff, highly plastic clay layer that is approximately 20 feet thick. This clay layer acts as an aquitard (confining layer) between the upper unconfined aquifer and the deeper confined aquifer. A sequence of sand and silty sand interbedded with clay and clayey silt lies stratigraphically below the confining layer. This interbedded zone comprises the “deep aquifer” underneath the site.

3.0 GROUNDWATER MONITORING NETWORK
The VWRF groundwater monitoring well network currently consists of 18 groundwater monitoring wells. The monitoring wells are listed below:

MW-F was abandoned prior to the Third Quarter 2014 sampling event; it had been dry since 2007. MW-B is no longer sampled per instructions received by City of Visalia from the CRWQCB. Six monitoring wells (MW-N, MW-O, MW-P, MW-Q, MW-R, and MW-S) were installed in April 2014 and added to the monitoring well network.

Monitoring wells with a number 1, 2, or 3 in their designation are clustered wells with each well completed at a different depth. Monitoring wells with numbers “1” and “2” in their designation are screened in the first encountered groundwater (upper aquifer) while the monitoring wells with a number “3” are screened in the deeper groundwater zone (deep aquifer). Monitoring well locations are shown on Drawing 1. Monitoring well construction details are included in Table 1.

Groundwater monitoring wells MW-G, MW-H1, MW-H2, MW-J1, MW-J2, MW-K1, MW-K2, MW-L, MW-M, MW-N, MW-O, MW-P, MW-Q, MW-R and MW-S are screened in the upper aquifer while monitoring wells MW-H3, MW-J3, and MW-K3 are screened in the lower (deep) aquifer.

4.0 FIELD ACTIVITIES
Groundwater monitoring activities were conducted on October 25, 29, 30 and November 10 of 2024. Twelve (12) monitoring wells had sufficient water for sampling during this monitoring event. Monitoring wells MW-G, MW-H1, MW-J1, MW-K1, MW-L and MW-M did not contain sufficient water to sample and were considered dry. Sampling activities included the following:
 Depth-to-groundwater was measured at each well prior to purging. Depth-to-water measurements and calculated groundwater elevations for the past five years are summarized in Table 1.
 Each monitoring well was purged of a minimum of three well volumes prior to sampling using a portable submersible pump, with the exception of MW-H3, MW-J3, and MW-K3.

Field parameters including temperature, electrical conductivity (EC), and pH were measured frequently during purging. Purging continued until these parameters were relatively stable. After purging, groundwater samples were collected in laboratory prepared sampling containers, labeled, and stored in a cooled ice chest. o Monitoring wells MW-H3, MW-J3, and MW-K3 could not be purged and sampled with the portable submersible pump because the water levels are too deep.

Samples were collected from MW-H3, MW-J3 and MW-K3, using a HydraSleeve™, a no purge sampling device.

 Sampling equipment was cleaned prior to purging and sampling each monitoring well.  Groundwater samples were transported under chain-of-custody to Moore Twining’s State of California certified analytical laboratory for analysis. 357

 Groundwater samples were analyzed for; pH, EC, Total Dissolved Solids (TDS), Total Nitrogen (Nitrate as Nitrogen, Nitrite as Nitrogen, and Total Kjeldahl Nitrogen (TKN)), Ammonia as Nitrogen, and General Minerals. Samples for metals were filtered with a

0.45 µm filter prior to preservation.

5.0 GROUNDWATER LEVELS
Depth-to-water was measured in the monitoring wells prior to purging. Depth-to-water measurements were used in conjunction with the surveyed top of casing elevations to calculate groundwater elevation in each monitoring well. A groundwater elevation contour map constructed using the data from monitoring wells screened across first encountered groundwater is shown in Drawing 2. A groundwater elevation contour map using the depth-towater data from the deeper aquifer monitoring wells is included in Drawing 3. Groundwater elevation data collected during the previous five years is summarized in Table 1. Hydrographs for the upper aquifer and lower aquifer monitoring wells are included in Appendix A.

Interpretation of the gradient and flow direction of the first encountered groundwater is complicated by several factors. Monitoring wells that are screened across first encountered groundwater, and when not dry, are in a generally linear pattern. Groundwater elevations appear to be significantly affected by water in both the on-site and off-site evaporationpercolation ponds. Regarding these factors, during the second 2024 semiannual monitoring event, in the area southwest of the facility, groundwater was interpreted to flow generally southwesterly at an estimated gradient of approximately 13.2 feet per mile (0.0025 feet/foot).

For reference, included as Drawing 4, is the California Department of Water Resources SGMA Data Viewer groundwater contour map from the fall of 2023. This was the most recent map available at the time this report was prepared.
(https://sgma.water.ca.gov/webgis/?appid=SGMADataViewer#gwlevels) During the second 2024 semiannual sampling event, groundwater in the deeper aquifer was determined to flow southwesterly at a gradient of approximately 16.86 feet per mile (0.0032 feet/foot).

6.0 GROUNDWATER QUALITY
Laboratory analytical results for groundwater monitoring events conducted by Moore Twining for the previous five years are summarized in Table 2. Time concentration graphs for selected constituents in upper aquifer monitoring wells are included in Appendix A. Copies of the laboratory reports are included in Appendix B.

Selected constituents from samples collected from groundwater monitoring wells screened in the upper aquifer and sampled in the second 2024 semiannual sampling event were compared to the average historical values of background groundwater monitoring well MW-N and are summarized below:
358
City of Visalia Water Reclamation Facility A76404.07
January 27, 2025 page 4
 Background monitoring well MW-N has a calculated average EC of 925 micro-Siemens per centimeter (µS/cm). During the recent sampling event, EC measurements in samples collected from the upper aquifer monitoring wells ranged from 580 µS/cm in MW-P to 1,400 µS/cm in MW-S. Except for MW-S, all monitoring wells sampled this quarter were below average background EC concentrations of 925 µS/cm.  Background monitoring well MW-N has a calculated average TDS concentration of 675 milligrams per liter (mg/L). During the recent sampling event, TDS concentrations in samples collected from the upper aquifer ranged from 350 mg/L in MW-P and MW-H2 to 930 mg/L in MW-S. With the exception of MW-S and MW-N, all monitoring wells sampled this quarter were below average background TDS concentrations of 675 mg/L.  Background monitoring well MW-N has an average nitrate as nitrogen (NO3-N) concentration of 41 mg/L. During the recent sampling event, NO3-N concentrations in samples collected from the upper aquifer ranged from 5.4 mg/L in MW-Q to 71 mg/L in MW-S. Apart from MW-S, all monitoring wells sampled this quarter were below average background NO3-N concentrations of 41 mg/L.

In the upper aquifer monitoring wells sampled this quarter, NO3-N concentrations equaled or exceeded the California Department of Public Health Primary Maximum Contaminant Level (MCL) of 10 mg/L in background monitoring well MW-N (40 mg/L) and downgradient monitoring wells MW-H2 (20 mg/L), MW-O (10 mg/L), MW-P (27 mg/L), and MW-S (71 mg/L).

Background monitoring well MW-N reported the second highest concentrations of NO3-N (40 mg/L) during this event. As such, the elevated NO3-N concentrations detected in the wells may also be contributed by sources other than VWRF due to the close proximity of animal confinement facilities and agricultural activities in the area.

7.0 CONCLUSIONS AND RECOMMENDATIONS
The 2024 second semiannual groundwater laboratory analytical results continue to show that elevated NO3-N concentrations (above the MCL) are present in background monitoring well MW-N. Additionally, background monitoring well MW-N reported the second highest elevated concentrations of NO3-N (40 mg/L) during this event. NO3-N concentrations reported in downgradient monitoring wells MW-H2 (20 mg/L), MW-O (10 mg/L), MW-P (27 mg/L), and MW-S (71 mg/L) also exceeded the MCL. However, the elevated NO3-N concentrations detected in the wells may also be contributed by sources other than VWRF due to the close proximity of animal confinement facilities and agricultural activities in the area.

Moore Twining recommends;
 To continue with semiannual groundwater monitoring activities. The 2025 first semiannual sampling event will be conducted in April 2025. 359

EC - electrical conductivity in micro Siemens per liter < 5 -
J - Detected but below the Reporting Limit; therefore, result is an estimated concentration. Same as DNQ - Detected, but Not Quantified. a -
HT5 - The hold time was missed due to instrument failure. The sample was later analyzed outside of hold time.

HD - Sample was originally analyzed within the EPA recommended holding time . However, it was reanalyzed with a dilution to confirm the result due to a high concentration of the target parameter. - Total Organic Carbon, Phosphate, Boron, Iron, and Manganese not required to be analyzed by WDR Order No. R5-2018-0046.

Analyzed for nitrate + nitrite as N by method SM4500-NO3 F because method EPA 300.0 was performed outside of hold time due to instrument failure. Nitrite as N (by EPA 300.0) was below the detection limit, therefore it is assumed that the detected concentration of nitrate + nitrite as N is primarily nitrate as N.Less than followed by the indicated laboratory detection limit (not detected), expect for total nitrogen.

Notes and Definitions
BLK02 Detected in the blank; associated samples were either ND, or >10x the amount detected.

BS2 Blank Spike Recovery for this analyte was biased low. Results were accepted based on Blank Spike duplicate result.

DUP1 A high RPD was observed between a sample and this sample's duplicate.

DUP2 RPD for duplicate analysis exceeded limits due to matrix interference.

J Detected but below the Reporting Limit; therefore, result is an estimated concentration ( CLP J-Flag). Same as DNQ - Detected, but Not Quantified.

MS2 Matrix Spike Recovery for this analyte was biased high; associated blank spike recovery is within range.

RPD Relative Percent Difference
µg/L micrograms per liter (parts per billion concentration units) ND Analyte NOT DETECTED at or above the reporting limit mg/L milligrams per liter (parts per million concentration units) mg/kg milligrams per kilogram (parts per million concentration units) Analysis of pH, filtration, and residual chlorine is to take place immediately after sampling in the field.

If the test was performed in the laboratory, the hold time was exceeded. (for aqueous matrices only) Moore Twining Associates, Inc. The results in this report apply to the samples analyzed in accordance with the chain of custody document. This analytical report must be reproduced in its entirety.

Notes and Definitions
BLK02 Detected in the blank; associated samples were either ND, or >10x the amount detected.

BS2 Blank Spike Recovery for this analyte was biased low. Results were accepted based on Blank Spike duplicate result.

DUP1 A high RPD was observed between a sample and this sample's duplicate.

DUP2 RPD for duplicate analysis exceeded limits due to matrix interference.

J Detected but below the Reporting Limit; therefore, result is an estimated concentration ( CLP J-Flag). Same as DNQ - Detected, but Not Quantified.

MS2 Matrix Spike Recovery for this analyte was biased high; associated blank spike recovery is within range.

RPD Relative Percent Difference
µg/L micrograms per liter (parts per billion concentration units) ND Analyte NOT DETECTED at or above the reporting limit mg/L milligrams per liter (parts per million concentration units) mg/kg milligrams per kilogram (parts per million concentration units) Analysis of pH, filtration, and residual chlorine is to take place immediately after sampling in the field.

If the test was performed in the laboratory, the hold time was exceeded. (for aqueous matrices only) Moore Twining Associates, Inc. The results in this report apply to the samples analyzed in accordance with the chain of custody document. This analytical report must be reproduced in its entirety.

Notes and Definitions
J Detected but below the Reporting Limit; therefore, result is an estimated concentration ( CLP J-Flag). Same as DNQ - Detected, but Not Quantified.

MS2 Matrix Spike Recovery for this analyte was biased high; associated blank spike recovery is within range.

MS3 Matrix Spike Recovery for this analyte was biased low; associated blank spike recovery is within range.

MS4 The spike recovery was outside of QC acceptance limits for the MS and/or MSD due to analyte concentration at 4 times or greater the spike concentration.

RPD3 The RPD is out of range for this spike and its duplicate due to a low or high bias of one of the two spikes.

(Moore Twining) when sampling groundwater monitoring wells are presented below. Moore Twining observes these procedures in order to obtain consistent, reliable data.

Groundwater sampling will be performed a minimum of 24 hours following development, or when the post-development water level in the well has returned to the static level. Before purging and sampling is performed, the depth to water and the total well depth will be measured. If floating hydrocarbons are suspected, a bottom-filling clear bailer, or hydrocarbondetecting paste bailer, or interface probe may be used to record floating hydrocarbon thickness. Depth to water will be measured with an electric sounder, according to Moore Twining's "Standard Operating Procedures for Measuring Depths to Water and Calculating Groundwater Elevations".

Prior to sampling a monitoring well, a minimum of 3 well casing volumes will be purged using a clean, stainless steel submersible pump or a disposable bailer equipped with a length of new rope. Disposable bailers and rope lengths will be used once and discarded. After 3 casing volumes of water have been removed from the well, purging will continue until measured field parameters (pH, specific electrical conductivity, and temperature) have stabilized. Purging data will be recorded on the Well Sampling log.

Some monitoring wells are expected to be evacuated to dryness after removing fewer than three casing volumes. These low-yield monitoring wells will be allowed to recharge for as long as 24 hours. Samples will be collected as soon as the monitoring wells have recharged sufficiently to allow sample collection. If insufficient water has recharged after 24 hours, the monitoring well will be recorded as "dry" for the sampling event.

Purged water will be containerized in Department of Transportation-approved drums, and stored on site in an area inaccessible to the general public. The purged water is typically characterized either by sampling, or on the basis of the groundwater sample analytical results.

Moore Twining can recommend an appropriate method for disposition of the purged water.

Disposal will be the responsibility of the client.

Water samples will be transferred into sample containers supplied by the analytical laboratory.

Sample containers will be labeled and placed in an ice-cooled chest, equipped with a thermometer, for transport to the laboratory. The temperature inside the ice-cooled chest will be recorded on chain of custody documents when samples are placed in the chest, and when they are received by the laboratory. Samples will be maintained at a temperature of approximately 4 degrees Centigrade.

Standard Operating Procedures for Equipment Decontamination: Proper decontamination procedures reduce the potential for: cross-contamination among sample locations; and introduction of contamination from outside sources. Sampling equipment and any tools, measuring devices, or other equipment which will contact soil, groundwater, or any media being assessed will be washed in a low-phosphate soap and water solution, and rinsed in clean water before each use. The type of soap used will depend upon project requirements.

Standard Operating Procedures for Sample Handling and Chain-of-Custody: Records are developed for samples which include: sampling date, sample type, location, job number, name of sampling personnel, and method of preservation. Each sample container is labeled immediately following collection. Chain-of-custody protocol, as described in United States Environmental Protection Agency, 1986, Test Methods for Evaluating Solid Waste, SW-846, Third Edition, is followed. Samples will be maintained at approximately 4C. Upon arrival at the laboratory, the samples will be preserved for analysis as appropriate.

Samples may be delivered to Moore Twining's chemistry laboratory in Fresno, California. The Moore Twining representative in charge of the field work transport or direct the transportation of the samples and custody forms to the laboratory, where the samples are transferred to the sample control department. A receiving clerk, or an authorized analyst, signs the custody forms, present a duplicate copy to the Moore Twining representative, and transfers the samples to a laboratory analyst. The laboratory manager retains possession of the custody forms during analyses of the samples.

The laboratory manager's responsibilities include monitoring the sample integrity within the laboratory. This involves assigning each sample a laboratory number and maintaining crossreference between the sample's field and laboratory identifications. The analysts' responsibilities include maintaining accurate records of the samples analyzed along with the analytical data produced. This involves labeling chromatograms and maintaining the laboratory numbers on sub-samples taken from the submitted samples, labeling glassware used in the analyses and properly labeling sample extract containers with each sample's laboratory number.

Following analyses, the samples are transferred to a limited-access storage room. Chain-ofcustody forms, chromatograms, and other pertinent information are filed for future reference.

Splits of samples analyzed are kept for 30 days. Samples containing hazardous concentrations will be returned to the client for disposal.

Standard Operating Procedures for Laboratory Quality Assurance/Quality Control: These laboratory QA/QC procedures were developed to reduce outside interferences during analyses of samples. The laboratory director is responsible for creating and maintaining the program.

General QA/QC procedures follow:
• Analytical instruments are serviced on a regular basis to assure an accurate calibration; • Organic-free water is monitored daily for quality;
• Gas chromatographs are calibrated daily;
• Method blanks are run to check whether the glassware and reagents are free of interference from chemicals that would invalidate the analyses; • Standards are prepared using the applicable reference materials; • Matrix spikes are analyzed in duplicate to validate the accuracy and precision of the method.
