PUBLIC UTILITY DISTRICT TO PERFORM
INVESTIGATIVE WORK FOR THE TAHOE SOUTH Y PCE
INVESTIGATION IN SOUTH LAKE TAHOE
Project Title
Investigative Work for the Tahoe South Y PCE Investigation in South Lake
Tahoe
Time Frame
Based on the following factors, the contract should be prepared and processed as
soon as possible. The purpose of the proposed project is to conduct investigation
activities to determine the source(s) of PCE contamination in the South Tahoe
Public Utility District's (STPUn's) municipal supply wells in South Lake Tahoe.
PCE concentrations currently exceed state drinking water MCLs by 28 times and
continue to increase annually. If PCE concentrations get too high; they will
exceed the capacity of the air stripping tower to remove the contaminant before
delivering municipal water to STPUD customers. PCE is carcinogenic at very
low levels.

The proposed term for this contract is January 5, 1998 to April 10, 1998. Contract
funds are provided by Cleanup and Abatement Account #27861, due to expire end
of FY 97198.
Civil Service Considerations
We are unaware of any state civil service entity that can conduct the necessary
investigation work for this contract in the time frame required.
Scope of Work
Under a pending resolution~ the STPUD Board agrees to collect soil samples)
water samples, and aquifer data in the South Y area of South Lake Tahoe, in order
to identify or narrow down the identity of sources of PCE contamination. The
work will be accomplished by installing monitoring well(s) and piezometers, and
conducting soil borings, aquifer tests, and laboratory analyses. All sampling
activities and locations will be decided in cooperation with Regional Board staff.
Being a non-profit public utility district, the STPUD Board will attempt to
contract with low-bid subcontractors for completing investigative work which can
not be done in-house. ·
Purpose and Objectives
The proposed project is intended to collect soil, water, and aquifer data in the
South Y area of South Lake Tahoe, to assist the Regional Board in identifying the
potential source(s) of PCE contamination. After the sources or sources are
determined, the Regional Board can require cleanup and abatement, and possibly
reimbursement of state's costs.
Statement of Work to be Performed
Under a pending resolution, the STPUD will be responsible for conducting
investigative work for identifying sources of PCE contamination in South Lake
Tahoe. Investigation work can include: installation of monitoring wells and
piezorneters; collection of soil samples beneath the Clement wellhouse building;
and conducting aquifer tests and laboratory analyses. The STPUD will conduct as
much of the work itself as possible or subcontract out the services. Upon
completion of the investigative work, the STPUD will submit the data to the
Regional Board within 45 days. ·

M/WIDVBE Considerations
The Contractor is a non-profit public utility district and does not meet the
M/W/DVBE participation requirements.
Sole Source Justification
The Regional Board is pursuing a sole source. contract because the Contractor has
completed previous investigative work in-house and with. low bid subcontractors,
to collect soil, water, and aquifer data in the South Y area of South Lake Tahoe.
Being the party affected by PCE contamination in municipal supply wells~ the
STPUD is motivated to conduct a timely investigation and at the least cost to
taxpayers.

by the STPUD, and (3) the STPUD makes an effort to obtain low-bid
subcontractors for completing all other work not done in-house.
