From: Martin Pastucha, Director, Public Works, Water Resources
Subject: Olympic Well Field Groundwater Management Contract Amendment
Recommended Action
Staff recommends that the City Council authorize the City Manager to negotiate and
execute a first modification to professional services agreement #9916 in the amount of
$584,736 (including a 5% and 10% contingency only on Task 2 and Task 5,
respectively) with ICF International, a Virginia-based company, for additional
groundwater program activities. This will result in a 4-year amended agreement with a
new total amount not to exceed $2,805,636, with future year funding contingent on
Council budget approval. The City will be reimbursed by the Gillette Company for
$355,995 upon completion of Tasks 2 and 3.
Executive Summary
ICF International (ICF) is the City's current environmental consultant responsible for
implementing the Olympic Well Field Groundwater Management Program. The Olympic
Well Field area has a long history of manufacturing and light industrial operations.
Releases from these industrial operations have led to the presence of volatile organic
compounds (VOCs) in groundwater produced from these wells. The Olympic Well Field
Groundwater Management Program ensures that the contamination is fully
characterized, captured and monitored. Five new additional groundwater tasks are
required for the Olympic Basin to keep the City in full compliance with State and local
regulatory programs.
The current agreement with ICF, in an amount not to exceed $1,732,500, ends on June
30, 2016, with two additional one-year renewal options in the amount not to exceed
$244,200 per year. A modification is required to include additional groundwater program
activities in an amount of $584,736 (including a 5% and 10% contingency per proposal,
only on Task 2 and Task 5, respectively) for a not to exceed total of $2,805,636 over a
four-year period, if all renewal options are exercised.
Background
On June 10, 2014, Council approved a Professional Services Agreement with ICF
International, to implement the Olympic Well Field Management Plan for a two-year
term ending June 30, 2016 with two additional one-year renewal options.

The Olympic Well Field Management plan was subsequently approved by the Los
Angeles Regional Water Quality Control Board (RWQCB). The Olympic Groundwater
Basin is the City's second largest drinking water aquifer and provides up to 1,500
gallons per minute (gpm) of groundwater for treatment and distribution to the City of
Santa Monica. The Olympic Well Field has been adversely impacted by contamination
from several former manufacturing facilities in the immediate area. This area of Santa
Monica has a long history of manufacturing and light industrial operations. Releases
from these industrial operations have led to the presence of volatile organic compounds
(VOCs) in groundwater produced from these wells. The City has entered into
Settlement and Release Agreements with Boeing and Gillette Company, which formerly
conducted business in the Olympic Well Field area. Funds from these settlements will
be used to build a new Olympic Well Field Drinking Water Treatment plant.
Five new additional groundwater tasks have been identified by Public Works/Water
Resources which require immediate attention by the City in order to successfully

ten years. Their original contract was to perform quarterly groundwater monitoring for
expanded to assist the City with negotiations with two Potentially Responsible Parties
(PRPs) in the Basin: Boeing and The Gillette Company. ICF currently is responsible for
implementing the Olympic Well Field Management Plan. The scope of work for this
amendment consists of five new additional tasks that are described in detail below. The
tasks include:
Task 1 - Addition of 1, 4-Dioxane Analysis to the Existing Quarterly Groundwater
Monitoring Program
In late 2014, the City began the design and construction of a pilot treatment system for
the Olympic Basin. It was determined that one of the critical groundwater contaminants,
2 of 5
1,4-Dioxane, needed to be fully characterized throughout the Olympic Basin to
determine the range of expected influent concentrations to the pilot plant and, in the
future, to the new Olympic Drinking Water Plant. Costs include all labor and expenses
associated with the addition of 1, 4-Dioxane for fifteen quarters (4Q 2014 through 2Q
2018) for 30 samples (14 from B-Zone wells and 15 from C-Zone wells, and one QA/QC
sample). All chemical analysis results would be reported in the quarterly monitoring
reports submitted to the RWQCB.
Task 2 - Installation and Development of Three Additional Groundwater Monitoring
Wells
th
Planned redevelopment activities at the former Papermate site (1681 26 Street) will
require the abandonment of all existing monitoring wells, with the exception of GW-14
and GW-18. Through discussions with the RWQCB staff, an agreement was reached
with Gillette for reimbursement for expenses related to the installation of three
replacement wells. The following activities are required for this task:
Task 2.1 - Planning, Permitting and Pre-field Preparation
Task 2.2 - Groundwater Monitoring Well Installation
Task 2.3 - Well Development
Task 2.4 - Management and Disposal of Investigation-Derived Waste
Task 2.5 - Well Surveying
Task 2.6 - Reporting
Task 3 - Installation of Dedicated Pumps in the New Groundwater Monitoring Wells
Following the completion of well development, ICF would install dedicated submersible
pumps in the newly installed monitoring wells. The use of dedicated pumps significantly
decreases the amount of time required at each well during sampling events, reduces
the volume of investigation-derived waste produced and eliminates the potential for
cross-contamination between wells. The cost for this task would be reimbursed by the
Gillette Company.
Task 4 - Production Well Siting Support
The City is in the process of evaluating suitable locations for additional groundwater
production wells in the Olympic Well Field and has hired a hydrogeologist as a water
resource expert to assist in this effort. The principal reason for the installation of the
3 of 5
production wells is to provide additional water supply. As part of this task, ICF would
support the efforts of the City's hydrogeologist as needed.
Task 5 - Redevelopment of Five Existing Groundwater Monitoring Wells
ICF is experiencing numerous problems with the new monitoring wells that were
installed in the Olympic Well Field. Fine sediment is preventing the pumps from
ability to conduct low-
flow groundwater removal requirements as set forth by the RWQCB has been
compromised. Redevelopment of the five wells would involve retaining a drilling
contractor with well development equipment and crew, field geologist, traffic control,
waste management and disposal, and overall project management.
Financial Impacts and Budget Actions
The agreement modification to be awarded to ICF is $584,736 for an amended
agreement total not to exceed $2,805,636. Funds in the amount of $584,736 for added
scope of work are included in the FY 2015-16 Capital Improvement Program budget in
account C019045.589000. The Gillette Company will reimburse the City for costs
expended under Tasks 2 and 5 of this add-on project for a total of $355,955, which
would be a net increase to the city of $228,781. Future year work and funding is
contingent on Council budget approval.
