Memorandum
To: Board of Directors
From: Ed Taylor
Date: 7/24/03
Date of Board Meeting: July 30, 2003
Subject: Consideration of proposal from Aqua Hydrogeologic Consulting to
provide supervision and documentation during the Geologic/Exploration drilling
program.
1. WHY THIS MATTER IS BEFORE THE BOARD
With the continuous proposed development within the Truckee Donner Public
Utility District service territory, it is imperative that the District explore and collect
data on the Aquafer to develop new water sources.
2. HISTORY
The District has used several techniques in exploring additional water sources.
We are proposing the utilization of a technique that is not only less expensive, but
will provide the information required to identify future well sites. This process will
identify geologic formations, water availability and will allow for water quality
sampling during the exploration.
3. NEW INFORMATION
The District staff has requested a proposal from Aqua Hydrogeologic Consulting
to supervise and document the process as further outlined in the attached
proposal.
4. RECOMMENDATION
I recommend that the Board approve the proposal from Aqua Hydrogeologic
Consulting for supervision and documentation during the Geologic/Exploration
drilling program in an amount not to exceed $51,447.00

RE: Scope of Work and Cost Estimate for Hydrogeologic Consulting Services for the
supervision and data collection during the Geologic/Exploration drilling program.
Dear Ed:
I am pleased to present this scope of work and cost estimate for the supervision and data
collection during the drilling of the proposed four geologic/exploration boreholes. A
topographic map is attached showing the approximate locations of the proposed exploration
drilling sites. The following summarizes the proposed work plan, a detailed scope of work and
cost estimate follows the summary.
• Prepare and submitted paperwork to Lahontan for the waste discharge permit waiver.
• Work together with TDPUD personnel in the development of the contractors bid
document and selection of the well drilling contractor.
• Provide on-site supervision and data collection during the drilling of the proposed
geologic/exploration boreholes.
• Evaluate data collected from the drilling program
• Prepare the report summarizing all activity and containing findings and
recommendations.
The above is a brief summary of the activity to be covered under this proposed scope of work.
The following is a more detail summary of each proposed task and a cost estimate to perform the
described work.
Scope of Work
Task 1 During Task 1, AquA will prepare and submit to Lahontan the application for the
waste discharge permit waiver. After the submittal of the paperwork to Lahontan,
AquA will track the process and take care of questions as they arise.. Also as part of
this task, AquA will put together the drilling bid document and provide the document
to TDPUD to be sent out to qualified drilling contractors. After the completed bids
are returned to the TDPUD, AquA will help evaluate the bids and provide a
recommendation to TDPUD for their consideration.
Task 2 AquA personnel will provide field supervision and data collection during the drilling
of the proposed four geologic/exploration boreholes. These activities will include

geologic logging of the boreholes to an estimated depth of 1,200 feet each,
accounting for drilling material used, recording drill rig activity, logging the time of
the drilling to determine penetration rates, evaluation of downhole geophysical
survey, collection
of water quality samples during the borehole drilling as deep as possible, and
abandonment of the boreholes per State of California regulations.
Task 3 This task will summarize in a report all of the activity that was completed in Task 2.
In addition, this report will contain findings, data analysis, and recommendations
regarding the potential capacity of a production well if it is constructed in the
immediate vicinity of the geologic/exploration borehole.
