Geohydrologic data for this well field and public water supply data for St. Charles County were compiled to assist US DOE in developing the St. Charles County well field contingency plan to ensure a supply of water in the event that the well field becomes contaminated from wastes (radioactive, nitroaromatic, other) stored in the Weldon Spring quarry. The well field consists of 8 wells penetrating the entire thickness of the Missouri River alluvial aquifer and is 98-116 feet deep. Aquifer tests were conducted on 3 occasions at 3 different locations in the well field. Calculated transmissivities range from 900 to 60,200 feet squared per day; hydraulic conductivities ranged from 23 to 602 feet/day. Calculated/estimated storage coefficients ran...
