• February, 2023 significant grant funds will be available to do Headworks Project • Special agreement needed to update the WDR Permit for Wastewater Plant, which needs to be done soon
Mayor Rhoades commented that the interconnect pipe already exists and was last used in 1997, and is already connected to the Tertiary Plant. Vice Mayor Atlan agreed that there is a pipe there, but believe it is the ARSA pipe.

Jim Scully handed out drawings of the Five Mile Bridge and the various pipes that are unused. If the pipe you are considering using is the white pipe that is on the up end of the bridge, that pipe is starting to degrade because of being out in the sun too long.

David Anderson:
• The proposed alignment only includes CDCR and does not affect ARSA • Regional Water Quality Control Board has advised you of the exposure to liabilities of taking CDCR contaminated water
• The pipeline already exists so the Interconnect is not necessary It was moved by Councilmember Epperson, seconded by Vice Mayor Atlan and carried to approve the agreement with West Yost for the Interconnection Piping Project.

1.0 INTRODUCTION
This groundwater monitoring report describes the results of the third quarter 2021 west of lone on the south bank of Sutter Creek in Section 26, T6N, R9E, Mount Diablo Baseline and Meridian, Amador County, California. A Vicinity Map is presented as Figure 1 in Appendix A. This Report is provided by EcoUrban Associates (EUA) at the request of the lone City Manager to comply with groundwater monitoring requirements in the Revised Monitoring and Reporting Program (MRP) No. R5-2013-0022 (Rev. 1), and Cease and Desist Order (CDO) R5-2014-0157, adopted December 5, 2014. A CDO was also received in 2019 (R5-2019-0701) requiring the City collect and analyze groundwater samples from wells P-3 and P-5B for the second and third quarter of 2019. Apparently, that work was never performed that year so it is being conducted in those said quarter this year. Other wells were listed in the CDO but they are either already being sampled or the wells are destroyed. The consultant was not made aware of this requirement until May of this year by the City Mayor. This report includes data from these two additional wells; results are summarized in Section 7.2 of this report.

A Site Map indicating the monitoring well locations is presented as Figure 2 in Appendix A.

Also included with this Report are field forms and laboratory analytical results. This Report was submitted to the City for review and comment and is submitted on the City's behalf by EcoUrban to the California Central Valley Regional Water Quality Control Board (RWQCB).

2.0 SITE DESCRIPTION
The WWTP is situated in lone Valley at the south corner of the intersection between West Marlette Street and Dave Brubeck Road (formerly Old Stockton Road). All monitoring wells are spread out across the valley and bordered to the north by Sutter Creek. The topography slopes toward the west slightly and the surrounding properties are primarily agricultural. A residential neighborhood is located adjacent to the northeast corner of the site.

2.1 Monitoring Network
The WWTP is monitored by an on-site network of nine groundwater monitoring wells and four piezometers. Each quarter, samples are collected from the nine wells and depth-to- - 1 -
water measurements are collected from the nine on-site monitoring wells, the four piezometers, and the six offsite monitoring wells (MW-08 series).

The groundwater monitoring well network consists of the following: MW-1 and MW-1A, located east of the WWTP; wells MW-2A, installed in July 2013, and MW-2 monitor groundwater downgradient from percolation Pond 5; well MW-2, located between Ponds 4 and 5 and Sutter Creek; and wells MW-3, MW-3A, MW-4, MW-4A, and MW-5A monitor downgradient groundwater. The collection of surface water samples from Sutter Creek is not required by the MRP. As previously mentioned, wells P-3 and P-5B have been added for this sampling event per CDO R5-2019-0701. As of the writing of this report, these wells are not required in future sampling events. The six offsite MW-08 series wells are located east and south of the WWTP. Deep wells are herein designated "A" and shallow wells "B".

Three inactive wells (MW-5, MW-6, and MW-7), were destroyed during the previous quarter as described in the Well Destruction Report dated August 15, 2017.

3.0 MONITORING AND REPORTING REQUIREMENTS
MRP No. R5-2013-0022 (Rev.1) specifies quarterly monitoring of the site wells. The groundwater elevation is measured at all locations, and then the wells are purged of at least three casing volumes until the pH, electrical conductivity (EC), and temperature stabilize. Temperature, pH, and EC measurements are collected during purging and at the time of sampling. The MRP specifies the quarterly analysis of groundwater samples for pH, total dissolved solids (TDS), nitrate as nitrogen (nitrate-N), ammonia as nitrogen (ammonia-N), dissolved iron, dissolved manganese, and total coliform organisms (TCO).

In addition to the quarterly analyses, the annual analyses include total nitrogen (TN), dissolved arsenic, aluminum, boron, calcium, magnesium, potassium, sodium, total alkalinity (including alkalinity series), chloride, sulfate, and hardness. These annual tests were conducted last quarter.

All analytical results are compared to groundwater limitations defined in the Waste Discharge Requirements Order R5-2013-0022-001 (WDR) and the CDO. Values used in this Report are included in Table A through E within the text of this report and in Tables 1, 2, and 3 of the tables section of this report.

The CDO specifies quarterly monitoring of well MW-2, MW-2A, MW-3, and MW-3A for pH, EC, dissolved oxygen (DO), oxidation-reduction potential (ORP), TDS, dissolved iron, and dissolved manganese. Results from these analyses are included in Appendix B of this Report.

Monitoring and sampling were performed by EcoUrban personnel who are trained in the operation of field-testing instruments. The field technician training includes instrument calibration in compliance with the manufacturer's recommended procedures and - 2 -
frequencies. Instrument calibration records are included with the field forms in Appendix A.

4.0 SAMPLING PROCEDURES AND WWTP POND ELEVATIONS

4.1 Quarterly Well Sampling
On September 19th and 21nd of 2021, EUA performed quarterly groundwater monitoring and sampling at the WWTP. The depth to water in all WWTP monitoring wells was measured using an electrical sounding tape decontaminated between wells. All wells were purged of at least three casing volumes of water using a dedicated disposable bailer.

Since dedicated bailers were used, no triple-rinse decontamination was performed for each well. Field parameters were recorded during purging with observation and documentation regarding the groundwater drawdown and recharge in each well. Purge rates ranged from approximately 0.5 gallon per minute (gpm) to 2.5 gpm, which is consistent with historical ranges.

All monitoring wells were observed to have clear to moderate clarity. No odors or sheens were noted in the purge water. All wells remained at least 80 percent of the pre-purge static water level while being purged and before being sampled. All purged water was discharged to the ground surface adjacent to its respective well.

All groundwater samples were placed in new, sterile laboratory-supplied sample containers supplied by the analytical laboratory, were labeled, and placed in an ice chest with ice pending same-day delivery to BC Laboratories, Inc. under chain-of-custody procedures. The groundwater elevations, field parameter measurements, and groundwater chemistry are in Tables 1, 2, and 3. Field observations of the water levels in the pond are presented in the following page in Table A. Elevations are based on reported average freeboard in monthly monitoring reports prepared by the City. - 3

5.0 GROUNDWATER ELEVATIONS AND GRADIENT
The depth to water in wells associated with the WWTP ranged from 7.81 feet in MW-08-1 to 24.50 feet in MW-3A. Depth-to-water measurements are used to calculate groundwater elevation. Measured depth to water is typically lowest (highest groundwater elevation) in Third quarter and highest (lowest groundwater elevation) in third quarter.

Compared to the previous quarter, the groundwater elevations in all wells decreased an average of 3.22 feet with no wells showing increased water elevations. The greatest change in groundwater elevation was a 5.51-foot decrease at MW08-4A. Hydrographs of the site groundwater elevation data are shown in Figure 4.

The groundwater gradient upstream and downstream from the WWTP and adjacent to Sutter Creek is down-valley (west) and parallel to Sutter Creek. Historically, various groundwater mounds or domes have been observed under the WWTF which may be caused by the abrupt curvature of Sutter Creek in the northwestern part of the WWTF and other potential factors like ground infiltration in the eastern part of the WWTF property or potential gravel channels in the northwestern part. The mound results in a relatively flat gradient [approximately 0.002 feet per foot (ft/ft)] between MW-1A and MW-1 east of the ponds and relatively steep (approx. 0.006 ft/ft) along the southern part of the property.

The average down-valley gradient is approximately 0.004 ft/ft. A map of the estimated potentiometric surface is shown in Figure 3.

6.0 LABORATORY ANALYTICAL RESULTS
Groundwater samples collected this quarter were analyzed by BC Laboratories, Inc. in Bakersfield, California. The laboratory data from this quarter along with the CDO required data are summarized in Table 2. The complete historical data set for the active groundwater monitoring wells are tabulated in Tables 1, 2 and 3. Existing California primary and thirdary Drinking Water Maximum Contaminant Levels (MCLs) are included in the tables and constituents occurring in concentrations greater than the MCLs are highlighted in yellow. In addition, TDS is compared to the Water Quality Goal (WQG) for Agricultural Use Protective Limits specified by the State Water Resources Control Board. Laboratory estimated values occurring below the Practical Quantitation Limits (PQL) and above the Method Detection Limit (MDL) are highlighted in blue. Laboratory certificates of analyses, quality control records, and chain-of-custody records are included in Appendix B.

7.0 DISCUSSION

7.1 Groundwater Elevation
The groundwater gradient indicates a west, southwest groundwater flow direction with a slope of approximately 0.004 ft/ft. As usual, groundwater elevations remain at levels highest in the Third quarter and lowest in the third. Mounding appears to be present in the northern, southeastern, and southwestern parts of the WWTF, as referenced above.

Groundwater gradient directions and magnitudes this quarter are generally consistent with historical ranges.

7.2 Water Quality
Below is a description of the analytes that were tested this quarter as required for quarterly and annual monitoring as compared to MCLs. Also note that wells P-3 and P-5B (MW-5B) were also sampled and tested per CDO R5-2019-0701
Groundwater limitations for TCO and Title 22 constituents are specified in the WDR. The TCO limitation is 2.2 most probable number per milliliter (MPN/100 ml) as a 7-day median.

For Title 22 constituents, laboratory results are compared to primary and secondary drinking water MCLs published by the Regional Board. TCO was detected above the MCL (2.2 MPN/100 ml) in six of the eleven wells sampled. TCO detection levels appear to have significantly and steadily decreased in samples over the past year, after a phase of a couple years when levels appeared to increase. Various wells have had sporadic TCO detection in the past, and more frequently in the wet season. It should be noted that detectable levels and levels over the TCO limitation continue to be observed in wells MW-1 and MW-1A, which indicates that sources of bacteria may also be from upgradient sources besides the WWTF.

Site pH results were within the agricultural beneficial use (WQO) of 6.5 standard units (SU) to 8.4 SU for all monitoring wells this quarter. The results for this event are within the pH range for the site and for most natural groundwater within the U.S.' Nitrate-N concentrations in all groundwater samples were below the drinking water primary MCL of 10 milligrams per liter (mg/L). Nitrate-N concentrations appear to have normalized below MCLs since 2016. Temporal changes in groundwater nitrate-N are shown in Figure 6.

Total nitrogen (TN) can be a preferred parameter when evaluating nitrogen impacts from wastewater treatment plants because it includes the sum of nitrate-N and total Kjedahl nitrogen (TKN), including ammonia-N. Nitrogen can convert to any of these forms depending on redox conditions and biological activity in soil. Although there is no numeric groundwater limitation for total nitrogen, the MCL for nitrate-N was applied. The highest TN concentration detected was from Well MW-3A which was detected a total nitrogen of

4.8 mg/L. Total nitrogen in groundwater and historical effluent are plotted in Figure 7.

Ammonia-N was detected above the taste and odor threshold of 1.5 mg/L in MW-2 mg/L, MW-2A, MW-3, and MW-3A. The highest detection of nitrogen was found in the form of ammonia-N and was observed at wells MW-3A (4.5 mg/L ammonia-N), MW-2A (3.8 mg/L), MW-2 (2.8 mg/L), and MW-3 (1.8 mg/L). Ammonia-N was detected at very low to trace levels in all other wells although reporting limits were above the MDL but below the PQL. These results are consistent with historic values.

TDS values in all wells were below the agricultural WQG of 450 mg/L and are graphed in Figure 10. The TDS: EC ratios for natural waters typically range from 0.55 to 0.75.2 The ratios in the third quarter 2021 ranged from 0.59 to 0.93 with an average ratio of 0.69.

Low (≤10 mV) oxidation-reduction potential (ORP) conditions were only present in MW-2A. This is generally consistent with historical measurements, albeit slightly more oxidized. Well P-3, which was only sample this quarter and last quarter, also had an ORP level of - 15 mV. Fluctuations with time in ORP are shown in Figure 11. 1 Hem, John D., Study and Interpretation of Chemical Characteristics of Natural Water, Geological Survey Water - Supply Paper H73, p63-64, 1978.

DO values are within the historical ranges for that parameter. DO values in downgradient wells MW-2, MW-2A, MW-3, MW-3A, MW-4, MW-4A, and MW-5A ranged between 0.76 mg/L (MW-3A) and 2.92 mg/L (MW-3). DO values in upgradient wells MW-1 and MW-1A, detected DO concentrations at 4.72 mg/L and 1.31 mg/L, respectively. Groundwater from wells is purged by the hand bailer method using dedicated disposable bailers.

The secondary MCL for manganese is 0.05 mg/L. Secondary MCLs are not health-based limits and this value is set at the concentration at which visible staining of plumbing fixtures can occur. Dissolved manganese exceeded the secondary limit in eight of the eleven wells sampled this quarter; this is all groundwater the samples except MW-1, MW-1A, and MW-4A. The highest dissolved manganese concentration (6.5 mg/L) was in the up-gradient/cross-gradient well MW-2 at the north side of the WWTF. This very possibly indicates that the manganese source is naturally occurring from lateritic bedrock conditions but are mobilized via oxidizing conditions along Sutter Creek. A 12-year upward manganese trend has been observed in MW-4 located down gradient from Pond 7 but it appears to have stabilized. A previous downward trend in MW-5A that started trending upward in December 2015 appears to also be normalizing. Total and dissolved manganese concentrations in groundwater versus time are plotted in Figure 8.

The secondary MCL for iron is 0.3 mg/L. Iron was not detected in any of the groundwater samples collected this quarter, including P-3 and P-5B. Since liners have been installed into ponds, iron levels appear to have become almost undetectable across the entire facility. Total and dissolved iron concentrations in groundwater versus time are plotted in Figure 9.

An assessment of analytical results from wells P-5B and P-3 does not indicate any conditions atypical of surrounding wells that have been monitored regularly.

The CDO specifies concentration limits for dissolved manganese and iron at MW-2, MW-2A, MW-3, and MW-3A. The October 2015, 2016, and 2017 Constituent Concentration Levels were not reached in time; anticipating this, the City submitted the 2020 Capacity Expansion Completion Report with information intended to meet the requirements on page 16 of the CDO Item 6B. In 2017, the City began draining and removing sludge from Ponds 1 through 4 in anticipating of lining these ponds. In the fourth quarter of 2019, the lining of the ponds was completed. The City is currently in the process of resolving the CDO. Long-term historic data as well as local hydrogeologic conditions indicate that the allegedly elevated manganese levels could be due to or related to naturally-existing conditions. Table B, Table C, and Table D are presented on the following page. These tables show the current concentrations in comparison with the - 7 -

8.0 CONCLUSIONS
- Various analytes that were tested as required for annual and quarterly monitoring were detected above MCLs.
-Coliform levels appear to have fallen back down to lower levels within the historic range. The contaminant appears to be naturally present in the groundwater both upgradient and downgradient.
- Groundwater elevations for the WWTP wells in the Third quarter of 2021 averaged approximately 3.22 feet lower than the previous quarter. - The secondary MCLs for dissolved manganese was exceeded in wells MW-2, MW-2A, MW-3, MW-3A, MW-4 and MW-5A. This is consistent with historic data. - The secondary MCLs for dissolved iron were not exceeded in any wells. The trend has decreased and stabilized at trace to non-detectable levels. - Secondary MCL for ammonia-N (1.5 mg/L) were exceeded in four wells (MW-2, MW-2A, MW-3, and MW-3A). MW-2 appears to be on a decreasing trend, which may be due to the recently lined ponds and emerging oxidizing conditions. - TDS concentrations were below the agricultural WQG in all wells. - The nitrate-N concentrations are below the primary MCL of 10 mg/L in all wells.

Historically, the highest nitrate-N concentrations are in upgradient well MW-1A but they appear to have remained relatively low and stable in recent years. - DO values in downgradient wells MW-2, MW-2A, MW-3, MW-3A, MW-4, MW-4A, and MW-5A ranged between 0.76 mg/L (MW-3A) and 2.92 mg/L (MW-3).

These levels are within historical ranges.
- ORP values this quarter are similar to historical values. Lowest (≤10 mV) ORP conditions were present deeper monitoring wells (MW-2A and MW-3A). Well MW- 2A was the only well were negative ORP levels were observed. All other wells show positive ORP results. This is consistent with historic ranges.

9.0 RECOMMENDATIONS
EcoUrban Associates recommends the following:
- Change sampling frequency from a quarterly basis to a semi-annual basis due to consistent trends that been established and revise the existing MRP No. R5- 2013-0022 (Rev1) accordingly.
- CDO No. R5-2014-0157 should be lifted due to evidence indicating that manganese and iron levels are naturally-occurring.
-CDO No. R5-2019-0701 will be fulfilled and P-3 and P-5B will not require purging, sampling, and analysis in subsequent sampling events.
