Established Regulatory Limits for Surface Water and Groundwater
Introduction
The regulatory limits for surface water and groundwater contained in
this database comprise chemical-specific preliminary remediation goals
(PRGs) based on potential Applicable or Relevant and Appropriate Requirements (ARARs).
These values should be used in conjunction with PRGs based on risk
assessment to ensure that the PRGs for a site meet the residual risk
requirements for protection of human health and the environment in the
National Oil and Hazardous Substance Pollution Contingency Plan (NCP).
In some cases, the values presented in this database may be To-Be-Considered
(TBC) Guidance because these values are superceded by site-specific state
requirements.
The 2009 Edition of the Drinking Water Standards and Health Advisories (EPA 822-R-9-011) is available
in pdf format here. Our Federal ARAR
database search tool uses the pdf version rather than the html version below.
*Always check the original sources of the ARARs for updates. Not every State is updated with the same frequency. |
