1.0 INTRODUCTION
This groundwater monitoring report describes the results of the Fourth Quarter/Annual 2021 groundwater monitoring and sampling activities at the City of lone (City) Wastewater Treatment Plant (WWTP) in lone, California. The WWTP is located approximately 1 mile 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 Michael Rock, 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 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- 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 - 1 -
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. The six offsite MW-08 series wells are located east and south of the WWTP. Of the MW-08 series, 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 not conducted this quarter.
All analytical results are compared to groundwater limitations defined in the Waste Discharge Requirements Order R5-2013-0022-001 (WDR) and the Cease and Desist Order (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 after the text of the 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.
EcoUrban personnel trained in the operation of field-testing instruments performed the monitoring and sampling. The field technician training includes instrument calibration in compliance with the manufacturer's recommended procedures and frequencies.
Instrument calibration records are included on the field forms in Appendix A. - 2 -
4.0 SAMPLING PROCEDURES AND WWTP POND ELEVATIONS
4.1 Quarterly Well Sampling
On December 12" and 14" of 2021, EUA performed quarterly groundwater monitoring at the WWTP. The depth to water in all WWTP monitoring wells was measured using an electrical sounding tape. 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 urging with observation and documentation regarding the groundwater drawdown an echarge in each well. Purge rates ranged from approximately 0.5 gallon per minut (gpm) to 2.5 gpm.
The field inspection sample collected from monitoring wells MW-2 and MW-3A were observed to have moderate clarity (slight orange, rust color), and the field inspection samples collected from MW-1, MW-1A, MW-2A, MW-3, MW-4, MW-4A, and MW-5A were observed to be clear. 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 pre-treated sample bottles 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, which are presented in the Tables section. 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 Table A - Freeboard and Elevation Changes (averages)

5.0 GROUNDWATER ELEVATIONS AND GRADIENT
The depth to water in wells associated with the WWTP ranged from 3.75 feet in MW-08-1 to 20.14 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 first quarter and highest (lowest groundwater elevation) in third quarter.
Compared to the previous quarter, the groundwater elevations in all wells increased an average of 4.71 feet. This was likely due to some of the strong rains that occurred in the early part of the storm season. No wells decreased in groundwater elevation. The greatest increase in groundwater elevation was a 6.01-foot increase at MW8-4A.
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 other factors like ground infiltration in the southeastern part of the WWTF property. The mound results in a relatively flat gradient [approximately 0.003 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 0.005 ft/ft. A map of the estimated potentiometric surface is shown in Figure 3. - 4 -
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 secondary 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 0.005 f/ft. As usual, groundwater elevations remain at levels highest in the first quarter and lowest in the third. Mounding appears to be present in the northwestern and southeastern 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.
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 all of the nine wells sampled. TCO detection levels have significantly increased in comparison to last two or three quarters. This is consistent to the pattern of sporadically higher TCO levels in the wet season.
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 - 5-
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). The well with the highest Nitrate-N concentration was MW-4 (7.2 mg/L). This increase of nitrate in MW-4 is likely due to infiltration in the WWTF Field from recent storms. Between 2014 and 2016, upward trends in nitrate-N appeared for MW-1A, MW-4, MW-4A, and MW-5A but have since normalized closer to its historic average. Temporal changes in groundwater nitrate-N are shown in Figure 6.
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. Beside MW-4 which was detected with 7.6 mg/L of TN, the highest total nitrogen for the form of ammonia-N was encountered at wells MW-3A (4.6 mg/L ammonia-N), MW-2A (3.3 mg/L), MW-1 (2.1 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-2A (3.2 mg/L), MW-3 (1.7 mg/L), and MW-3A (5.1 mg/L). Ammonia-N levels reduced significantly from previous quarters in well MW-2 (0.76 mg/L) and was detected slightly above PQL levels (0.1 mg/L PQL) in MW-1 (0.21 mg/L). All other wells was not detecteable (<0.067 mg/L). Other than the low levels detected in MW-2, the 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 fourth quarter 2020 ranged from 0.87 to 0.99 with an average ratio of 0.94.
This is higher than historic ranges. It appears that although the field meter was calibrated, it was reading conductivity levels lower than usual.
Low (≤10 mV) oxidation-reduction potential (ORP) conditions were only present in MW-2A (-21 mV). ORP levels appear to have been gradually increasing ever since the pond 1 Hem, John D., Study and Interpretation of Chemical Characteristics of Natural Water, Geological Survey Water - Supply Paper H73, p63-64, 1978.

liners have been installed Fluctuations with time in ORP are shown in Figure 11.
DO values are within the historical ranges for that parameter. DO values in downgradient wells MW-1A, MW-2, MW-2A, MW-3, MW-3A, MW-4, MW-4A, and MW-5A ranged between 1.19 mg/L (MW-3A) and 3.06mg/L (MW-1A). 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 six of the nine wells; all groundwater samples except MW-1, MW-1A, and MW4A. The highest dissolved manganese concentration (6.4 mg/L) was in the downgradient well MW-3A at the northwest side of the WWTF. 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 also appears to 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. Dissolved iron MCL exceedances occurred in two of the nine wells, downgradient wells MW-2A (0.93 mg/L) and MW-3A (1.0 mg/L). All remaining wells were trace to non-detect (<0.030 mg/L) for iron. Since September 2013, detectable levels of iron in MW-2, MW-2A, and MW-3A have decrease approximately an order of magnitude lower and appear to be normalizing at lower levels. Since liners have been installed into ponds, iron levels appear to have become almost undetectable. Total and dissolved iron concentrations in groundwater versus time are plotted in Figure 9.
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 Cease-and-Desist Order Item 6B. In 2017, the City began draining and removing sludge from Ponds 1 through 4 in anticipating of lining these ponds.
As of the fourth quarter of 2019, the lining of the ponds was completed. Table B, Table C, and Table D are presented on the following page. These tables show the current concentrations in comparison with the 2015, 2016, and 2017 concentration limits. - 7 -

7.3 Results from Annual Laboratory Analysis
All analytes that were tested this quarter as required for annual monitoring were within historic ranges and below secondary MCLs in applicable parameters. -8-
8.0 CONCLUSIONS
- Various analytes that were tested as required for annual and quarterly monitoring were detected above MCLs.
-Coliform levels have risen from previous quarters but within the historic range for sampling performed in the fourth quarter, which typically has elevated levels. The contaminant appears to be naturally present in the groundwater. - Groundwater elevations for the WWTP wells in the fourth quarter of 2021 averaged approximately 4.71 feet higher 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. The CDO concentration limits were exceeded in MW-2, MW-2A, and MW-3A for the years 2015, 2016, and 2017. - The secondary MCLs for dissolved iron were exceeded in two wells (MW-2A and MW-3A). Decreasing and stabilized trends continue to be exhibited. - Secondary MCL for ammonia-N were exceeded in all wells except MW-1A, MW-4, MW-4A, and MW-5A.
- 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 wells MW-1 and MW-1A but they appear to have remained relatively low and stable in recent years.
This quarterm the highest nitrate-N level was detected in MW-4, just west of the WWTF Field. This may be due to infiltration from recent storms. - DO values in downgradient wells MW-2, MW-2A, MW-3, MW-3A, MW-4, MW-4A, and MW-5A ranged between 1.20 mg/L (MW-2A) and 2.50 mg/L (MW- 4A). These levels are within historical ranges.
- ORP values this quarter are similar to historical values. Lowest (≤10 mV) ORP conditions were present in MW-2A. This is consistent with historic ranges.
9.0 RECOMMENDATIONS
EcoUrban Associates recommends the following:
- Change quarterly groundwater monitoring to a semi-annual basis since trends appear to be normalizing
-Continue monitoring and sampling for same analytics as described in revised MRP No. R5-2013-0022 (Rev1) and CDO No. R5-2014-0157.
