AGENDA TITLE: Approve Plans and Specifications and Authorize Advertisement for Bids for Central
Plume — Mid Plume PCE/TCE Groundwater Treatment Project
MEETING DATE: December 16, 2015
PREPARED BY: Interim Public Works Director
RECOMMENDED ACTION: Approve plans and specifications and authorize advertisement for bids for
Central Plume — Mid Plume PCE/TCE Groundwater Treatment Project.
BACKGROUND INFORMATION: The Central TCE/PCE Plume is bound by Pine Street to the north,
Stockton Street to the east, Pleasant Avenue to the west, and Park Street
to the south. Reports prepared by Langan Treadwell Rollo, the City's
PCE/TCE consultant, indicate that the PCE plume has migrated southerly toward the intersection of Church
and Tokay Streets.
This project (Exhibit A) is intended to capture and contain the plume migration, and consists of a groundwater
extraction well, granular activated carbon (GAC) treatment unit, a metal enclosure, electrical and site work, and
other incidental related work, all as shown on the plans and specifications for the above project. The Central
Regional Water Quality Control Board has reviewed and concurs with the proposed workplan.
Staff has worked closely with Lodi Unified School District to minimize the impact to Needham School. The
GAC treatment unit will be constructed in a steel enclosure placed entirely inside the public right-of-way. The
project includes an element of drought resistant landscaping to soften the enclosure's appearance.
The plans and specifications are on file in the Public Works Department. The planned bid opening date is
January 21, 2016.
FISCAL IMPACT:
FUNDING AVAILABLE:
There will be additional costs associated with the operations and maintenance of
this facility that will be funded by the PCE/TCE fund.
Funding for this project will be Central Plume Settlement Funds (190)
Project Estimate: $460,000
