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, MW- 2, 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.

First Quarter 2023 Groundwater Monitoring Report
R5-2013-0022-REV1 October 16, 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:
• +/- 0.2 for pH • +/- 2.0 degrees Celsius
• +/- 10% for EC • +/- 20mv for ORP
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 (NHA-N), dissolved iron (Fe), dissolved manganese (Mn), and total coliform organisms (TCO) were subcontracted to BSK Associates (BSK).

DL'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 TCO utilizing Standard Method 9221B.

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: lone WWTF, Groundwater Monitoring Report, Third 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 lone Wastewater Treatment Facility (WWTF) in lone, 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 lone Wastewater Treatment Facility, Groundwater Monitoring Network Report, R5-2013-0022-REV1, Third Quarter 2023 prepared by DLI.

GROUNDWATER ELEVATION
Well locations and depth to water measurements for the third quarter 2023 groundwater sampling event at the lone WWTF site were provided in Attachment 2 of the DLI report. The top casing elevations were obtained from the previous consultant's work product, provided by the City of lone. 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 based on the contours for the sample date is approximately 0.003 feet per foot (ft/ft) to the west. According to the discussion by the previous consultant, groundwater gradient was to the west-southwest at approximately

0.005 ft/ft in the 4*h quarter of 2021. Provost & Pritchard has calculated the gradient since 4*h quarter 2022 between 0.004 and 0.005 ft/ft and between west and southwest. Thus, this quarter's gradient is slightly flatter but in a direction 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 1s* quarter and the lowest in the 3rd quarter. This quarter (3rd) groundwater elevations decreased about 1.0 to 4.8 feet from the previous quarter, consistent with historical trends. Changes in groundwater elevation this quarter from the 3d quarter of 2022 generally increased between 0.7 and 5.2 feet with a decrease in just one well (MW-2A) of 0.2 feet.

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.

This quarter TCO was reported lower than historic results in MW-1A and was not detected in the other wells.

Ammonia concentrations over time appear to be trending slightly down in MW-2, MW-2A, and MW-3A, and relatively stable in the remainder of wells, but increased in most of the wells from last quarter. Field pH and total dissolved solids (TDS) concentrations appear to be fairly consistent over time and were within historic range this quarter. Dissolved iron concentrations have been trending downward since about 2016, however has been somewhat elevated in MW-2A recently. Manganese appears to be increasing over time in MW-4, which had a slight decrease this quarter, with no apparent trend in the other wells. lippeng.com\pzdata\clients\Dellavalle-1020\102022001-Ione WWTP & Castle Oak GW Consulting\600 Deliverables\/one WWTF\2023 Q3\2023 Q3 lone WWTF Discussion.docx

The historical quarterly analytical results do not illustrate strong spatial trends in the concentrations of TCO or NO3-N. Historical field pH measurements may have a weak spatial trend, however values across wells generally 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-1 did have the lowest TDS concentration but MW- 1A (upgradient) was highest, as was true last quarter.

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, although MW-4 and -4A had their highest reported values. Dissolved iron is historically elevated in MW-2A, MW 3A, and MW-2, in descending order and low to not detected in the remaining wells, which was true 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 continued this quarter, except for an increase in concentration in MW-2A to above MW-3 concentration.

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; iron in MW-2, MW-2A and MW-3A; and manganese (secondary MCL) in MW-2, MW-2A, MW-3, MW-3A, MW-4, MW-4A, and MW-5A.

Dear Mayor Rhoades and Members of the City Council,
you for considering Peckham & McKenney for the City of lone recruitment for City Manager.

Peckham & McKenney would be honored to represent you and the City of lone in this important search and specifically finding the right candidate for working with the City Council, serving residents, and achieving your goals.

As a mid-size, long-standing, and boutique firm, Peckham & McKenney is known for achieving successful and long-term placements. Among many of our strong attributes, these are four key reasons cities choose us:
• We actively and personally search for and find candidates. We don't just rely on ads and posts to attract applicants. We have an extensive network, use the telephone, email and LinkedIn, and sell the opportunity.
• We limit the number of concurrent searches to directly focus on serving our client. • We prioritize communicating with our clients and applicants to keep everyone informed. • Your recruiter is personally and directly responsible for all aspects of the search and your one point of contact.

As an executive recruiter for the firm, I'm proud of what we do because our team's values and priorities are to assist public agencies in furtherance of good government; place quality above quantity; and build long lasting relationships with those in the public service
Our Peckham & McKenney team is comprised of retired City executives who are passionate about the public sector. For example, 1 am a 27-year veteran of local California government including serving 15 years as City Manager for the Town of Los Altos Hills. I am very familiar with the responsibilities of a small-town City Manager and the expectations of the position. Moreover, I know and understand what is necessary to find good candidates and I have a strong, excellent network for attracting candidates.
