Memorandum will be the basis for identifying data gaps and developing locations for the
field data collection program described in Tasks 33.

. The draft Technical Memorandum will be updated into a final Technical Memorandum
after adding new aquifer configuration information obtained under Task 35 and addressing
State conunents on the draft Technical Memorandum.

. The Technical Memorandum will be provided in draft final form to the State for review
and comment. The Consultant will incorporate the comments and reconunendations from
the State, and provide a final Phase I Lower South Platte Region Aquifer Configuration
Report. Six hard copies and one digital copy in MSWord and Adobe Acrobat PDP format
will be provided to the State.

Tasks 32 and 43: Collection, Analysis and Mapping of Aquifer Property Data

Objective:

The objective of these tasks is to (1) compile existing aquifer property information and create
HydroBase-compatible databases with data from the Denver Basin and Lower South Platte
Regions, (2) help identify additional data needs in these Regions, (3) support the design of the
groundwater field program described in Task 33, and (4) enhance HydroBase with aquifer
property data collected during the Phase I field activities in Tasks 35 and 36.

Approach:

Task 32

Collect Historic Aquifer Property Data

. Obtain existing electronic databases that are currently maintained by the State and, if
available, the USGS and the available paper-copy reports (as identified in Appendix B7 of
the SPDSS Feasibility Study) that contain information on (a) hydraulic conductivity, (b)
transmissivity and (c) specific yield and storage coefficient.

Task 43.1

Analyze and Map Historic Aquifer Property Data

. Coordinate with the Relational and Spatial System Integration Consultant to detennine the
database structure that will be used for entry and/or formatting of these historic data.

. Reformat the existing electronic databases into the appropriate DSS (Hydro Base ) formats

. Evaluate whether the non-electronic historic data is suitable for addition to the SPDSS
database. These data will be evaluated to determine if it may provide an enhanced
understanding of the Denver Basin and Lower South Platte Regions' ground water
systems. Data that are necessary for future use to configure, calibrate and use in the
groundwater models that are a part of the SPDSS will be converted to an electronic format
and added to HydroBase.

. Summarize the database for descriptive purposes, including the database fields, number of
entries in each field by aquifer, and sources of data.
