EPA also works with facilities in the short-term to address soil/sediment exposure routes that may cause negative impacts to ecosystems. In situations where, from an engineering perspective, it is not possible to restore all or part of a groundwater plume, EPA may waive applicable or relevant and appropriate requirements (ARARs) and establish alternative, protective remedial strategies. October 1996, OSWER Publication 9283.1-12, EPA 540-R-96-023 On this page: Guidance for Groundwater Cleanups Guidance for Soil/Sediment Cleanups Guidance for Air (Vapor Intrusion) Cleanups Guidance for Groundwater Cleanups EPA's corrective action goal for groundwater is to prevent adverse effects to human health and the environment, both now and in the future. The serious health effects of lead are known learning difficulties in children; problems in the nerves, kidneys, liver and pregnancy risks. To begin to address pollution prevention or reme-diation, we must understand how surface waters and ground waters interrelate. Explosion hazards may pose an imminent and substantial danger to human health and public welfare. With respect to long-term cleanup goals, facilities and regulators generally focus first on cleanup activities that limit the exposure risk to humans.

This document is the first volume of three reports that address assessing the potential applicability of MNA as part of a groundwater remedy for plumes with non-radionuclide and/or radionuclide inorganic contaminants. Share sensitive information only on official, secure websites. While the elevated levels of various inorganic constituents could be attributed to natural processes, such as geological . The current state of the art in detection approaches for these chemicals are discussed along with recommendations for future research to further improve the methods. Water resources are scarce commodities, and preserving groundwater quality is of critical concern. The section provides guidance on groundwater use determinations. June 2009, OSWER Directive 9283.1-33. Procedures that minimize disturbance to the aquifer will yield the most representative groundwater samples. Then the focus shifts to cleaning up and restoring currently used and reasonably expected sources of drinking water as well as groundwater that is closely hydraulically connected to surface waters, whenever such restorations are practicable and attainable.

The Corrective Action Program requires such facilities to conduct investigations and cleanup actions (remediation of the contamination) as necessary to protect human health and the environment. Guidance documents do not impose legally binding requirements on EPA, States, or the regulated community, and may not apply to a particular situation based upon the specific circumstances of the Corrective Action facility.

September 1994, OSWER Publication 9355.4-16FS, EPA 540-F-94-049. This memo explains the purpose of the reforms, the types of remedy updates anticipated, and the process for updating remedies. April 2018, EPA 542-F-18-001. The main methods used include: containment, soil washing, thermal treatment, vapor extraction, bio-remediation, incineration, and other physical/chemical treatments. (4) Class C includes wastewater treatment plants having one (1) or more of the following: (A) Secondary treatment facilities that treat wastewater loads equal to or Applicability of RCRA Section 3020 to In-Situ Treatment of Ground Water (PDF) (6 pp,388 K) Groundwater pollution is imminent in most developing countries as a result of increased anthropogenic activities apart from possible natural pollutants. This memo clarifies the relationship between ARARs and protectiveness. The latest report, the 16th edition, compiles and analyzes Superfund remedial actions selected in fiscal years (FYs) 2015, 2016 and 2017, and provides trends since FY 1982. This document provides guidance on writing Records of Decision (RODs), Explanations of Significant Differences (ESDs) and ROD amendments.

July 1999, OSWER Memorandum 9200.1-23P, EPA 540-R-98-031 Over the years, new groundwater treatment technologies and approaches have become available allowing flexibility in how cleanup goals can be achieved. EPA developed this guidance to support implementation of Superfund Reform Initiative 9a: Risk Sharing. Monitored Natural Attenuation of Inorganic Contaminants in Ground Water, Volume 3: Assessment for Radionuclides Including Tritium, Radon, Strontium, Technetium, Uranium, Iodine, Radium, Thorium, Cesium, and Plutonium-Americium (PDF)(147pp, 7.1 MB) Guidance Promotion of Innovative Technologies in Waste Management Programs (PDF) (12 pp, 1.2 MB) April 1996, OSWER Policy Directive 9380.0-25, EPA 542-F-96-012 This directive describes EPA initiatives to facilitate the testing, demonstration and use of innovative cleanup and field measurement technologies. EPA recognizes the central role of the states and tribes in making groundwater protection decisions; if a state has an EPA approved Comprehensive State Groundwater Protection Plan or other codified groundwater standards that meet the regulatory criteria, those are the standards that will drive the groundwater cleanup. Protecting groundwater sources usually requires the combined efforts of many partners such as public water systems, communities, resource managers, and the public. Epidemiological studies have shown that the poor quality of drinking water as the main transport route has been responsible for many water-borne diseases. March 1998, OSWER Directive 9010.02.
