First Quarter 2023 Groundwater Monitoring Report
R5-1993-0240-002 April 10, 2023
As required by California Business and Professions Code Section 7835, groundwater monitoring site locations, potentiometric measurements, groundwater elevations, and analytical results summary discussions have been prepared by a Licensed California Geologist and are presented in Attachment 1 - Groundwater Elevation and Analytical Results Discussion. Groundwater elevations and depth to water measurements (DTW) with historical graph trends are presented in Attachment 2 - Groundwater Monitoring Network Measurements and Graphs.

GROUNDWATER MONITORING & SAMPLING
Prior to purging and sampling, Del-Tech measured DTW in all monitoring wells and piezometers. DTW was measured from the north side and top edge of well casing. DTW measurements (ft) are subtracted from the depth of well (ft) to determine standing water column (SWC) measurements in feet. The SWC is multiplied by the gallons per foot of depth (0.1632 for 2-inch diameter well casing) to determine calculated purge volume. All well casings are 2-inch polyvinyl chloride.

Dedicated Waterra tubing and check-ball systems are installed at each well, and all monitoring wells were purged and sampled with an inertial pump. Each monitoring well was purged to remove standing water within the well casing that may not be representative of formation water. Purge water samples were monitored in the field for temperature, pH, electrical conductivity (EC), oxidation-reduction potential (ORP), turbidity, and dissolved oxygen (DO). All purged water was released to the ground.

Instrument calibration was carried out daily in the field prior to measuring purge parameters.

Field records for water sampling events are included in Attachment 3 - Field Records.

Groundwater samples were collected for laboratory analysis after a minimum of three well casing volumes of water had been removed and the field parameters for purge water had stabilized. During sampling, DTW measurements were taken and recorded for draw-down after each purge. The following target criteria for three consecutive measurements were used to define stabilization:
 temperature +/- 0.1 degrees Celsius
 specific conductance +/- 3%
 pH +/- 0.1 units
 ORP +/- 10 millivolts
Samples were collected in the appropriate laboratory prepared containers, labeled, and placed directly into an ice cooled chest and delivered under chain-of-custody protocols by the project manager to DLI’s analytical laboratory. Samples for metals analysis were filtered prior to preservation and digestion using a 0.45-micron filter.

Castle Oak Golf Course
First Quarter 2023 Groundwater Monitoring Report
R5-1993-0240-002 April 10, 2023
As requested, groundwater samples were analyzed at DLI for pH, electrical conductivity (EC), total dissolved solids (TDS), Nitrate-N (NO3-N), ammonia as nitrogen (NH4-N), dissolved iron (Fe), and dissolved manganese (Mn). Samples for total coliform organisms (TCO), dissolved arsenic (As), and Volatile Organic Carbons (VOCs), were contracted out to BSK Associates (BSK).

DLI’s analytical laboratory is certified by the Environmental Laboratory Accreditation Program (Certificate No. 1595) for the analyses provided herein. BSK is certified by the Environmental Laboratory Accreditation Program (Certificate No. 1180) for the analyses provided herein.

Historical water quality trends and graphs are presented in Attachment 4 - Historical Water Quality Data and Graphs. Copies of the laboratory analytical reports for this quarter are included in Attachment 5 - Reports of Water Analysis (Monitoring Wells).

RE: Castle Oaks Golf Course, Groundwater Monitoring Report, First Quarter 2023, Groundwater Elevation and Analytical Results Discussion Dear Ms. Rubin:

This document was prepared by Provost & Pritchard Consulting Group (Provost & Pritchard) for Dellavalle Laboratory, Inc. (DLI) for the Castle Oaks Golf Course in Ione, California, which is subject to Monitoring and Reporting Program (MRP) R5-93-0240-002. The following discussion is based on the information presented in the Castle Oak Golf Course, Groundwater Monitoring Report, First Quarter 2023, R5-1993-0240 (report) prepared by DLI.

Groundwater Elevation
Well locations and depth to water measurements for the March 2, 2023 groundwater sampling event at the Castle Oaks site are provided in Attachment 2 of the DLI report. Top of casing elevations were obtained from the previous consultant’s work product, provided by the City of Ione. Groundwater elevations were calculated and are shown on the enclosed Groundwater Elevation Map, prepared by a Provost & Pritchard Professional Geologist. The calculated groundwater gradient across the Castle Oaks site for the sample date is approximately 0.004 feet per foot (ft/ft) to the southwest. According to the discussion by the previous consultant, groundwater gradient has been historically to the southwest at approximately 0.004 to 0.007 ft/ft, thus this quarter’s gradient is consistent with historical flow.

Based on hydrographs produced using historical groundwater elevations at the site, seasonal trends are not apparent, and the groundwater elevation has been trending slightly downward over time. This quarter groundwater levels were measured at the highest since 2019. This quarter groundwater levels in the monitoring wells increased between 1.5 and 4 feet from the previous quarter. From the first quarter of 2022 to this quarter the groundwater level increased between 1 and 2.5 feet. The 3 piezometers had water levels approximately 2 feet higher than the first quarter of 2022, after being dry the last 2 or 3 quarters.

Analytical Results
Based on the laboratory report in Attachment 5 of the DLI report, this quarter ammonia, arsenic, iron, and volatile organic compounds (VOCs) were not detected in the groundwater samples analyzed. Total coliform bacteria (TCO) were not detected in CO MW-2 and were highest in upgradient CO MW-1. Manganese was detected only in CO MW-3, which historically has had the highest concentration. The field pH ranged from 5.96 in MW-2, historically the lowest, to

6.96 in MW-1. Field electrical conductivity (EC) and total dissolved solids (TDS) had the lowest concentration upgradient in CO MW-1 and highest in CO MW-2, which is consistent with Dellavalle Laboratory, Inc. April 21, 2023
Castle Oaks Golf Course Groundwater Monitoring, 1st Quarter 2023 Page 2 of 2 Job No. 1020-22-001
G:\Dellavalle-1020\102022001-Ione WWTP & Castle Oak GW Consulting\600 Deliverables\Castle Oaks\2023 Q1\2023 Q1 CO Discussion.docx historical trends. Nitrate as nitrogen (NO3-N) had the highest concentration upgradient in CO MW-1, also consistent with historical trends.

Based on the graphs in Attachment 4 of the DLI report, most constituent concentrations appear to be relatively consistent over time, except for the following exceptions. NO3-N appears to be historically increasing in CO MW-1 and recently in CO MW-3. Iron appears to have decreased in CO MW-3 historically.

Groundwater limitations are not set for this site in the associated Waste Discharge Requirements and so concentrations are compared to respective primary or secondary maximum concentration limits (MCLs) identified in Title 22 of the California Code of Regulations.

According to the table in Attachment 4 of the DLI report the MCL was exceeded for NO3-N in MW-1, and secondary MCLs were exceeded for pH, EC, and TDS in CO MW-2, and for TDS and manganese in CO MW-3.

Limitations
This document has been prepared for the sole use of DLI, the City of Ione, and involved regulatory agencies. Any other person or entity without the express written consent of Provost & Pritchard Consulting Group may not rely upon this document.

Provost & Pritchard’s professional services were performed consistent with generally accepted environmental principles and practices in California at the time the services were performed.

No assessment can eliminate uncertainty regarding the potential for recognized environmental conditions. This document is intended to reduce, but not eliminate this uncertainty, recognizing reasonable limits of time and cost. Subsurface variations cannot be known, or entirely accounted for, despite exhaustive testing. This document should not be regarded as a guarantee that no further recognized environmental conditions are present on or beneath the site, beyond that which could have been detected within the scope of work.

In developing this report, Provost & Pritchard has relied on information that was prepared or provided by others. Provost & Pritchard assumes that this information is accurate and correct, unless noted. Changes in existing conditions at the site due to time lapse, natural causes, or operations on adjoining properties, may deem the information inappropriate.

No guarantee or warranty, expressed or implied, is made.

Respectfully,

First Quarter 2023 Groundwater Monitoring Report
R5-2013-0022-REV1

Dear Ms. Gedney:

This report summarizes the 1st Quarter 2023 groundwater monitoring and analytical sampling event associated with Monitoring and Reporting Program (MRP) R5-2013- 0022-REV1.

AUTHORIZATION
The services provided by Dellavalle Laboratory, Inc. (DLI), Provost & Pritchard Consulting Group (P&P), and Del Tech Geotechnical Support Services (Del-Tech) were authorized by the City of Ione and Dellavalle Project Manager, Lisa Rubin.

CITY OF IONE WWTF GROUNDWATER MONITORING NETWORK
As of 2 March 2023, the City of Ione Wastewater Treatment Facility (WWTF) groundwater monitoring network consists of nine (9) onsite monitoring wells, four (4) piezometers, and six (6) offsite monitoring wells (Table 1 - Network Site Descriptions). Each quarter, samples are collected from the onsite monitoring wells and depth-to-water (DTW) measurements are collected from the onsite monitoring wells, the piezometers, and the offsite monitoring wells (MW-08 series).

As required by California Business and Professions Code Section 7835, groundwater monitoring site locations, potentiometric measurements, groundwater elevations, and analytical results summary discussions have been prepared by a Licensed California Geologist and are presented in Attachment 1 - Groundwater Elevation and Analytical Results Discussion. Groundwater elevations and depth to water measurements (DTW) with historical graph trends are presented in Attachment 2 - Groundwater Monitoring Network Measurements and Graphs.

GROUNDWATER MONITORING & SAMPLING
Prior to purging and sampling, Del-Tech measured DTW in all onsite monitoring wells from the north side and top edge of the well casing. DTW measurements (ft) are subtracted from the depth of well (ft) to determine standing water column (SWC) measurements (ft). The SWC is multiplied by the gallons per foot of depth (0.1632 for 2- inch diameter and 0.6528 for 4-inch diameter well casings) to determine calculated purge volume. All well casings are 2-inch polyvinyl chloride, except for MW-5A, which has a 4- inch diameter.

Dedicated Waterra tubing and check-ball systems were installed in MW-1, MW-1A, MW2, MW-2A, MW-3, MW-3A, MW-4, and MW-4A and purged and sampled with an inertial pump. Dedicated tubing was installed in MW-5A, but due to the required purge volume of water, this onsite well was sampled and purged with an electronic centrifugal pump. Each onsite monitoring well was purged to remove standing water within the well casing that may not be representative of formation water. Purge water samples were monitored in the field for temperature, pH, electrical conductivity (EC), oxidation-reduction potential (ORP), turbidity, and dissolved oxygen (DO). All purged water was released to the ground.

Instrument calibration was carried out daily in the field prior to measuring purge parameters. Field records for water sampling events are included in Attachment 3 - Field Records.

City of Ione Wastewater Treatment Facility
First Quarter 2023 Groundwater Monitoring Report
R5-2013-0022-REV1 April 10, 2023
Groundwater samples were collected for laboratory analysis after a minimum of three well casing volumes of water had been removed and the field parameters for purge water had stabilized. During sampling, DTW measurements were taken and recorded for draw-down after each purge. The following target criteria for three consecutive measurements were used to define stabilization:
 temperature +/- 0.1 degrees
Celsius
 specific conductance +/- 3%
 pH +/- 0.1 units
 ORP +/- 10 millivolts
Samples were collected in the appropriate laboratory prepared containers, labeled, and placed directly into an ice cooled chest and delivered under chain-of-custody protocols by the project manager to DLI’s analytical laboratory. Samples for metals analysis were filtered prior to preservation and digestion using a 0.45-micron filter.

As requested, quarterly groundwater samples were analyzed at DLI for pH, electrical conductivity (EC), total dissolved solids (TDS), Nitrate-N (NO3-N), ammonia as nitrogen (NH4-N), dissolved iron (Fe), dissolved manganese (Mn), and total coliform organisms (TCO) were subcontracted to BSK Associates (BSK).

Historical quarterly water quality data and trend graphs are presented in Attachment 4 - Historical Quarterly Groundwater Quality Data and Graphs and the annual standards minerals historical data is presented in Attachment 5 - Historical Annual Standard Minerals Groundwater Quality Data. Copies of the laboratory analytical reports for this quarter are included in Attachment 6 - Reports of Water Analysis (Onsite Monitoring Wells).

RE: Ione WWTF, Groundwater Monitoring Network Report, First Quarter 2023, Groundwater Elevation and Analytical Results Discussion Dear Ms. Rubin:

This document was prepared by Provost & Pritchard Consulting Group (Provost & Pritchard) for Dellavalle Laboratory, Inc. (DLI) for the Ione Wastewater Treatment Facility (WWTF) in Ione, California, which is subject to Monitoring and Reporting Program (MRP) R5-2013-0022 (REV1).

The following discussion is based on the information presented in the Ione Wastewater Treatment Facility, Groundwater Monitoring Network Report, R5-2013-0022-REV1, First Quarter 2023 prepared by DLI.

Groundwater Elevation
Well locations and depth to water measurements for the March 2, 2023 groundwater sampling event at the Ione WWTF site were provided in Attachment 2 of the DLI report. Top of casing elevations were obtained from the previous consultants work product, provided by the City of Ione. Groundwater elevations were calculated and are shown on the enclosed Groundwater Elevation Map, prepared by a Provost & Pritchard Professional Geologist. The calculated groundwater gradient across the WWTF site for the sample date is approximately 0.004 feet per foot (ft/ft) to the southwest, the same as last quarter. According to the discussion by the previous consultant, groundwater gradient was to the west-southwest at approximately 0.005 ft/ft in the 4th quarter of 2021, thus this quarter’s gradient seems consistent with historical flow.

Based on hydrographs produced using historical groundwater elevations at the site, it appears that often the highest groundwater elevation occurs in the 1 st quarter and the lowest in the 3rd
quarter. This quarter (1
st) groundwater elevations increased about 2.5 to 10.5 feet from the previous quarter, consistent with historical trends, and between 0.3 and 3 feet from the 1 st
quarter of 2022. Groundwater elevations are highest since 2019. Groundwater levels in MW-08- 2A and MW-08-2B differed significantly this quarter, so the level from the shallower well, MW08-2B, was utilized for contouring.

Analytical Results
Based on the quarterly analytical results in Attachment 4 of the DLI report, this quarter’s results were fairly consistent with historical temporal trends. Total coliform organism (TCO) and nitrate as nitrogen (NO3-N) concentrations have no apparent increasing or decreasing trend but have had large variations over the years. TCO was reported lower this quarter than recent results in most of the wells. NO3-N increased in many of the wells this quarter. Ammonia concentrations appears to be trending slightly down in MW-2, MW-2A, and MW-3A, and relatively stable in the remainder of wells. Field pH and total dissolved solids (TDS) concentrations appear to be fairly Dellavalle Laboratory, Inc. April 21, 2023

G:\Dellavalle-1020\102022001-Ione WWTP & Castle Oak GW Consulting\600 Deliverables\Ione WWTF\2023 Q1\2023 Q1 Ione WWTF Discussion.docx consistent over time. TDS increased in many of the wells this quarter. Dissolved iron concentrations have been trending downward over time and was not detected in the monitoring wells this quarter. Manganese appears to be increasing over time in MW-4, which continued this quarter, with no apparent trend in the other wells.

The historical quarterly analytical results do not illustrate spatial trends in the concentrations of TCO or NO3-N. Historical field pH measurements may have a weak spatial trend, however values across wells have a tight range and are not easily discernible. TDS concentration appears to have a spatial trend, with MW-1 (upgradient) historically having the lowest concentration and MW-3 (downgradient of ponds) often having the highest concentration. This quarter MW-2A (cross-gradient of ponds) and MW-1 and had the lowest and second lowest TDS concentration and MW-1A (upgradient) was highest, with MW-3 the second highest. The wells nearest the ponds generally have elevated concentrations of ammonia, dissolved iron, and dissolved manganese relative to the other wells. Ammonia is historically highest in MW-3A, MW-2A, MW-2, and MW-3, from highest to lowest concentrations, and low or not detected in the other wells. Ammonia concentrations were within historical spatial trends this quarter except for MW-2A being slightly lower than MW-2. Dissolved iron is historically elevated in MW-2A, MW-3A, and MW-2, in descending order and low in MW-3 and the remaining wells, but was not detected this quarter. Dissolved manganese concentrations have a historical spatial trend of MW-3A, MW-3, MW-2, and MW-2A being elevated, in order of highest to lowest, and downgradient MW-4 slightly elevated. The dissolved manganese trend was continued this quarter.

Groundwater limitations for the site are set at 2.2 MPN/100mL as a 7-day median for total coliform and at respective primary or secondary maximum concentration limits (MCLs) identified in Title 22 of the California Code of Regulations. Groundwater limitation values were exceeded for TCO in MW-1A, MW-2, MW-4, MW-4A, and MW-5A; NO3-N in MW-1A; and manganese (secondary MCL) in MW-2, MW-2A, MW-3, MW-3A, MW-4, and MW-5A.

Provost & Pritchard’s professional services were performed consistent with generally accepted environmental principles and practices in California at the time the services were performed.
