Section Env-Ws 379.07 - Conceptual Hydrogeologic Model

(a) A conceptual hydrogeologic model of the source of water for the proposed well shall be developed by a person who, by education and experience in hydrogeology, is able to quantitatively analyze and interpret hydrogeology.

(b) The conceptual hydrogeologic model shall:

(1) Identify the sources of information used;

(2) Provide an explanation of how interpretations were made; and

(3) Include the following:

a. A description of the geology and geologic history of the area;

b. Generalized geologic cross-sections through the aquifer based on available information such as well logs, geologic reports, maps, and subsurface data;

c. A description of:

1. Aquifer flow;

2. Hydraulic boundaries;

3. Recharge conditions;

4. The interaction of the source of the withdrawal with surrounding water resources; and

5. The estimated zone of contribution; and

d. A conceptual groundwater flow net map for the aquifer and its recharge areas within a one mile radius of the proposed withdrawal based on available data, which shall show:

1. Hydraulic head contours; and

2. Groundwater flow directions in both horizontal and vertical planes, under average, ambient, non-pumping conditions for the aquifer being considered and its recharge areas.

(c) The conceptual hydrogeologic model shall be refined based on results of the pumping test performed in accordance with Env-Ws 388.15 and shall be presented in the final report.
