Groundwater has been identified as an increasingly important natural resource in the United States. Municipalities and industrial and agricultural interests have become more dependent on groundwater sources to supply drinking, process and irrigation water requirements. At the same time, recognition of the vulnerability of groundwater to contamination has heightened. Previously, groundwater was thought to be protected from contamination by natural geologic processes. We now know that frequent and widespread incidents of groundwater contamination can result from organic and inorganic chemicals, radio nuclides and microorganisms.

Underground storage tanks for fuel and chemicals were among the first point sources of groundwater contamination to receive the attention of legislators and regulators. Tank system leaks due to corrosion, piping failures, improper construction and installation mistakes and environmental releases due to spill sand overfills have been targeted for control. Regulations are now in place, or proposed for implementation, to address site investigations, monitoring studies, tank system installations, product and tank inventory control, tank replacement, design and installation standards and remedial action. In addition, much regulatory attention has recently been focused on the appropriate procedures and formulas to evaluate damage to or impairment of use of the groundwater resource.
