<br />' 14. <br />' 7. CONCLUSIONS <br />1. Aquifer analysis of Stollsteimer Creek alluvium indicates the <br />formation is highly permeable and has a transmissivity of <br />' approximately 100,000 gpd/f t. <br />' 2. Utilizing data from a constant discharge test and computer simu- <br />lation of actual site conditions, representative values for thel.o~¢~ <br />' Fruitland ~rmation hydrologic properties were within one order <br />of magnitude. Transmissivity values ranged from a low value of <br />' 30 gpd/ft to a high value of 500 gpd/f t. Most representative <br />values are within the range of 130 to 320 gpd/ft with a median <br />value of 210 gpd/f t. <br />3. Calculated inflows to the active pit area as determined by corn- <br />' puter simulation indicates inflow of about 10 gpm. <br />' 4. Estimated inflow to the proposed Barren Ridge pit, as determined <br />by using climatic data and hydrogeologic aquifer properties, is <br />in the range of 0.5 to 1 gpm. <br />Respectfully Submitted <br />D.R.
