The groundwater below the ANL-E site is monitored through the collection and analysis of samples obtained from the on-site water supply wells and from a series of groundwater monitoring wells located near several sites that have the potential for causing groundwater impact. Federal and state drinking water regulations are used to evaluate the quality of groundwater used for human consumption at ANL-E. Regulations establishing comprehensive water quality standards for the protection of groundwater have been enacted -- IEPA Groundwater Quality Standards, 35 IAC, Subtitle F, Part 620.31 In addition, demonstration of compliance with the groundwater protection requirements in DOE Order 5400.1, as related to sitewide characterization studies and monitoring well requirements, is presented in this chapter. The permit for the 800 Area landfill requires a groundwater monitoring program; the program was initiated in July 1992.
