• The Consultant will provide six hard copies and one digital copy (in MSWord and Adobe
Acrobat PDF format) of the Draft Technical Memorandum for the State's review. The
Consultant will incorporate the State's comments and recommendations and provide a Final
Technical Memorandum. Six hard copies and one digital copy in MSWord and Adobe
Acrobat PDF format of the Final Technical Memorandum will be provided. It is anticipated
that the State will provide a summary of the aquifer test data and results for a given test to the
well owner who collaborated with the well testing.
Task 36: Construction and Testing of Bedrock Wells
Objective:
The objective of this task is to extend Phase 1 collection of new aquifer property and water level
field data from the bedrock ground water system in the Denver Basin Region. This will be
accomplished through the use and testing of existing wells and/or through the construction and
testing of a new well. This task will further address the SB-74 recommendations regarding the
collection of data to better define aquifer properties of the Denver Basin Region bedrock aquifers.
Comment:
This Task is coupled with Task 37, Aquifer Pumping Tests. In the SPDSS FS a total of 4
bedrock wells were recommended to be drilled. One well was installed in Phase 1. Based on the
data collection effort in Phase l, only one additional well is recommended for Phase 2. As
included in Exhibit D, Task Compensation , one bedrock well will be constructed under this Task
and 10 bedrock aquifer pumping tests using existing wells will be performed under Task 37.
However, if more than ten sites are identified in Task 37 where existing wells can be used to
collect aquifer property data (that the Consultant determines to be of sufficient quality), then the
Consultant will meet with the State to discuss the use of the existing wells from which to collect
aquifer property data instead of drilling the new well. If the proposed new bedrock well is not
drilled, then up to ten additional aquifer pumping tests will be performed under Task 37 at no
change in cost from that presented in Exhibit D, Task Compensation.
Approach:
Task 36.1 Bedrock Well Construction and Testing
The Phase 2 program may include the installation, testing and monitoring of water levels in a
single well completed by the Consultant in the Denver Basin Region bedrock aquifers. The
drilling, installation and testing of wells by the Consultant under this Task will commence after
the State provides written approval the Phase 2 Field Study Workplan (Task 33). All construction
techniques will be in accordance with State Statutes. If any of the following approach items are
found to conflict with such statutes, the State Statutes shall prevail.
