Several years ago the Institute implemented a series of strategies to assess the impact and manage the migration of lead from its existing shooting ranges. These strategies were shaped after a careful review of geologic maps to assess drinking water sources, hydrologic maps to assess drainage patterns on and surrounding shooting ranges, soil maps to assess soil properties that affect the migration lead in the soil, wetland maps to determine any potential impact of lead into wetlands, and topographic maps to determine site elevations, drainage, and dissipation on the property. This effort led to a series of steps to improve the existing drainage collection system, reduce surface water runoff velocity, and assess the lead parameters found in water runoff. Today, the Institute monitors lead migration using three experimental ponds behind the earthen berms of its "dirty" ranges. In addition, the Institute has implemented "clean" ranges where only lead-free, non-toxic ammunition is permitted for use by agency personnel using the ranges.
