Camp Humphreys, Korea, Groundwater Assessment
Abstract
This study was conducted to (a) determine the current groundwater production capacity using the pumping data from 21 production wells; (b) estimate potential recharge from rainfall and surface water sources; (c) determine total groundwater availability using precipitation and soil data, and predict the future water use assuming a potential increase of camp population from 7,500 to 40,000; and (d) estimate water availability in a land zone adjacent to the Camp Humphreys area. Several modeling approaches were evaluated for the preliminary calculation of water budget at the site. Among these approaches, the Hydrologic Evaluation of Landfill Performance computer program suited the limited hydrogeological data that were available for the site. The recharged and stored water in the subsurface of the existing Camp Humphreys appears to be adequate for the current camp population usage. This assessment's model conditions predicted a potential recharge of nearly 4 billion gallons per year to the aquifer beneath land adjacent to the west side of Camp Humphreys and terminating at the Anseong River. If all of this aquifer recharge were available for withdrawal, it would meet future population needs for the expansion of Camp Humphreys (assuming a population of 40,000). However, the actual availability of this estimated aquifer recharge to new supply wells constructed in the adjacent land will depend highly on the density and hydrogeologic characteristics of bedrock fracturing, overlying soil and land use conditions, and groundwater quality conditions.
