AGENDA TITLE: Adopt Resolution Authorizing City Manager to Execute Task Order No. 25 of the
Master Professional Services Agreement for PCE/TCE Cleanup with Treadwell &
Rollo, a Langan Company, of San Francisco ($23,500) and Appropriating Funds
($28,000)

RECOMMENDED ACTION: Adopt resolution authorizing City Manager to execute Task Order
No. 25 of the Master Professional Services Agreement for PCE/TCE
Cleanup with Treadwell & Rollo, a Langan Company, of
San Francisco, in the amount of $23,500 and appropriating funds in the amount of $28,000.
BACKGROUND INFORMATION: The City of Lodi is responsible for the cleanup and monitoring of
volatile organic carbon compounds (primarily PCE/TCE) in the four
areas referred to as the Central, Southern, Western and Northern
plumes. For several years, the City has been monitoring 50 wells, as specified in the Groundwater
Monitoring and Reporting Program Number R5-2008-0813 (MRP) and presenting quarterly reports to the
California Regional Water Quality Control Board (RWQCB). These monitoring wells are mostly
concentrated in the Central Plume area, but others are scattered across the area bounded by
Lockeford Street, Stockton Street, Kettleman Lane, and Hutchins Street. These wells are constructed to
various depths.
Recently, the City Council approved solicitation of bids to construct eight additional monitoring wells that
will be generally deeper than existing wells and will be located to monitor the Southern and Western
plumes. These wells will ultimately be included in the MRP later this calendar year.
For two years, the City has been operating soil vapor extraction wells and a groundwater extraction well
in the block bounded by Pine Street, Church Street, Oak Street, and Pleasant Avenue. This soil vapor
extraction system replaced the pilot facility that operated for several years prior at Guild Cleaners. Total
PCE removed by these facilities exceeds 8,500 pounds.
Recently, Treadwell & Rollo performed an update to the Lodi Groundwater Model by adding new data for
the Central plume and historic and new data for the Southern, Western and Northern plumes. The model
is now being used to simulate the migration of the plumes under various City groundwater well field
pumping scenarios. In addition, the model is being used to optimize locations for proposed monitoring
wells in the Southern, Western and Northern plume areas.
Task Order No. 25 will draw upon the expertise and experience of Treadwell & Rollo to develop the
ongoing work program and future costs for the City to complete the remediation and monitoring of the
groundwater contamination associated with the Central, Southern, Western, and Northern plumes. Task
Order No. 25 is provided in Attachment A. Staff Ncommends approval and the appropriation of $28,000.

Subject: Proposal to Prepare City -Wide Remediation and Monitoring Costs
Task Order 25
City of Lodi, California
Dear Mr. Schwabauer;
Treadwell & Rollo, a Langan company, is pleased to present this proposal to develop the estimated tasks
and future costs for the City of Lodi to complete the remediation and monitoring of the groundwater
contamination associated with the Northern, Central, Western, and Southern groundwater plumes. Our
proposal is based on the following assumptions and deliverables for the:
• The Northern, Western, and Southern Plumes will not require active remediation, and will
be monitored using current and new groundwater monitoring wells designed and
installed specifically for long-term monitoring of plume migration.
• The Central Plume Source Area soil vapor and groundwater remediation system
performance will be assessed and a reasonable time frame for continued operation will
be determined. The cost to decommission and remove the system and subgrade utilities
(including soil vapor and groundwater extraction wells and monitoring wells) associated
with the system will be estimated.
An estimated cost to remediate downgradient groundwater contamination that has
moved beyond the Central Plume Source Area remediation system capture zone will be
developed, based on the assumption that the Regional Water Quality Control Board
(Water Board) will mandate remediation in this area. Remedial alternatives will be
estimated, including retrofitting the Central Plume Source Area treatment system to
accept water from extraction wells:
The term of the monitoring period for each plume will be estimated using the City-wide
groundwater flow model, assessment of the results and trends of the current
groundwater monitoring program, and discussions with the Water Board. We will include
a monitoring optimization analysis that statistically analyzes groundwater monitoring
trends and describes acceptable changes in long-term monitoring. (Note — we will also
assume that all groundwater monitoring data is available in an electronic format suitable
for this analysis).
• An estimated cost to abandon all groundwater monitoring wells will be prepared.
• Annual future reporting costs for the City-wide groundwater monitoring program will be
estimated using current monitoring costs, anticipated changes in monitoring frequency,
and a reasonable annual increase based on local financial projections.
• We will include a task to meet with the Water Board to discuss the goals and initial
objectives of this work and solicit their advice on data requirements and cleanup goals,
and a second meeting to present the long-term plan that will come from this work.
