Assessing and managing groundwater contamination

As a leading protector of human health and the environment, the EPA has developed a best-practice framework for assessing, managing and cleaning up contaminated groundwater.

Contaminated groundwater may harm human health or the environment, and may also affect the types of land uses that may safely be carried out on a contaminated site.

Some activities which may lead to groundwater contamination include

  • leaking underground petroleum storage systems, for example, service stations poorly managed landfills
  • accidental chemical spills or leaks at industrial sites

The guideline provides information on

  • how to conduct preliminary and detailed assessments
  • strategies for controlling contamination
  • guidance on clean-up and remediation
  • regulation of contaminated sites
