TO: Honorable Mayor and City Council
FROM: Paul Cranmer, Public Works Services Director
By: John Corona, Utilities Superintendent
SUBJECT: RESOLUTION NO. 7475 AMENDING THE FISCAL YEAR 2022-23 WATER
FUND OPERATING BUDGET AND AUTHORIZING A BUDGET
APPROPRIATION FOR CARBON EXCHANGE SERVICES FOR THE LIVE
OAK WELL GAC TREATMENT SYSTEM IN THE AMOUNT OF $148,983,
OFFSET BY A REDUCTION IN THE WATER RESERVE FUND; AND
APPROVING A PURCHASE ORDER WITH CALGON CARBON
CORPORATION FOR CARBON EXCHANGE SERVICES FOR THE LIVE
OAK GAC TREATMENT SYSTEM IN THE AMOUNT OF $213,983
CEQA: Exempt
Recommendation: Adopt and Approve
SUMMARY
The Public Works Services Department (“PWSD”) is responsible for the daily operation
of City wells and the water that is distributed to the community. Water quality samples
are taken regularly to ensure optimal water quality. In October 2018, water quality
samples at Live Oak Well indicated that the well was impacted by Trichloroethylene
(“TCE”), a volatile organic compound. Since TCE concentrations at Live Oak Well
exceeded the allowable standards, a treatment system using Granular Activated Carbon
(“GAC”) to remove TCE was constructed. Based on the State Water Resources Control
Board (“SWRCB”) permit for operations, when the effectiveness of the GAC system
wanes, new carbon filters must be installed.
It is recommended that the City Council adopt Resolution No. 7475 amending the Fiscal
Year 2022-23 Water Fund Operating Budget and authorizing a budget appropriation for
Carbon Exchange Services for the Live Oak GAC Treatment System in the amount of
$148,983, offset by a reduction in the Water Reserve Fund; and approve a Purchase
Order with Calgon Carbon Corporation for Carbon Exchange Services for the Live Oak
GAC Treatment System in the amount of $213,983.

BACKGROUND
The PWSD operates the City’s water distribution system, which provides water service to
more than 56,000 residents through approximately 14,000 service connections. The City
uses ground water wells as the primary source of water supply to meet the demands of
water use in the City. Water quality samples are taken regularly to ensure optimal water
quality.
In October 2018, water quality samples at Live Oak Well indicated that the well was
impacted by TCE, a volatile organic compound. TCE is a federal and state regulated
contaminant with a Maximum Contaminant Level (“MCL”) of 5 parts per billion. Since TCE
concentrations at Live Oak Well exceeded the allowable MCL, it was determined that a
system to treat TCE would need to be constructed. On February 5, 2019, the City Council
approved a Professional Services Agreement (“PSA”) with Calgon Carbon Corporation
for the construction of a GAC Adsorption System for Live Oak Well.
DISCUSSION
In July 2021, the City began operating the Live Oak GAC treatment system to remove
TCE from the Live Oak Well aquifer. Based on contaminant levels documented in 2018,
it was estimated that the GAC Adsorption System would need to be exchanged every 16
months. The City originally planned to exchange one vessel beginning in FY22-23 and
budgeted $65,000 in the Water Fund Operating Budget. However, four lead vessels have
reached their carbon saturation level at the same time and all four need to be exchanged.
It is crucial for the Live Oak Well to remain operational as it is a top producing well and
the only source of water supply in Pressure Zone 4. Furthermore, based on the SWRCB
permit for operations, once the GAC lead vessels experience contaminant breakthrough,
a mandatory GAC exchange must be scheduled.
Calgon Carbon Corporation was awarded the original contract to supply the GAC for the
treatment system. The GAC provided is specific to Arcadia’s treatment needs and will be
recycled for reuse only at our Live Oak Treatment facility. Due to these specific
requirements and to avoid any possible cross contamination, Calgon Carbon Corporation
meets the criteria to be considered a sole source provider.
ENVIRONMENTAL IMPACT
This project is considered a Class 1 exemption as defined in Section 15301(b) & (d) of
the California Environmental Quality Act (“CEQA”), since the project consists of
restoration or rehabilitation of deteriorated or damaged facilities to meet current standards
of public health and safety. This project is categorically exempt per the California
Environmental Quality Act as an existing facility, Section 15301 of the CEQA guidelines.

FISCAL IMPACT
Funds in the amount of $65,000 were budgeted in Fiscal Year 2022-2023 Water Operating
Budget. The total cost to exchange all four lead vessels is $213,983. A budget
appropriation from the Water Reserve Fund in the amount of $148,983 is requested for
the remainder of the Carbon Exchange Services for the Live Oak Well GAC Treatment
System.
RECOMMENDATION
It is recommended that the City Council determine that this project is exempt under the
California Environmental Quality Act (“CEQA”); and adopt Resolution No. 7475 amending
the Fiscal Year 2022-23 Water Fund Operating Budget and authorizing a budget
appropriation for Carbon Exchange Services for the Live Oak Well GAC Treatment
System in the amount of $148,983, offset by a reduction in the Water Reserve Fund; and
approve a Purchase Order with Calgon Carbon Corporation for Carbon Exchange
Services for the Live Oak GAC Treatment System in the amount of $213,983.
