Groundwater Quality Standards Public Hearing

Event Description

Groundwater Quality Standards for the protection of groundwaters of the state are established by 15A NCAC 02L .0202. They are the maximum allowable concentrations resulting from any discharge of contaminants to the land or waters of the state, which may be tolerated without creating a threat to human health or which would otherwise render the groundwater unsuitable for its intended best usage as an existing or potential source of drinking water supply for humans. Every three years the State is required by 15A NCAC 02L .0202(g) to review its groundwater water quality standards and interim maximum allowable concentrations to determine if changes are needed and, if necessary, to make those changes. Revision of these standards is needed to ensure that they contain the most recent health and toxicological information. The last review focused on the interim maximum allowable concentrations established under 15A NCAC 02L .0202(c).

Proposed changes to 15A NCAC 02L .0202 include:

•             the adoption of a groundwater quality standard for 44 substances with established                    interim maximum allowable concentrations, some with revisions,
•             the addition of a groundwater quality standard for three substances (2,6-                                  dinitrotoluene, strontium, and total PFOA and PFOS) without established interim                      maximum allowable concentrations,
•             the organization of the groundwater standards into a table,
•             the addition of Chemical Abstracts Service Registry Numbers (CASRNs) for the                        groundwater standards,
•             the removal of synonyms,
•             a change in some units of measure to parts per billion (µg/L), when appropriate,
•             the addition of rule text to add a notification process for the establishment of an                      interim maximum allowable concentration, and
•             the addition of rule text to clarify the triennial review process.
