Introduction to Remediation Standards
These rules implement the provisions of the Brownfield and Contaminated Site Remediation Act, N.J.S.A. 58:10B-12, and other statutes,
by establishing standards for the remediation of contaminated ground water, surface water, soil, soil leachate and indoor air. These rules supplement the requirements of the
Technical Requirements for Site Remediation rules, N.J.A.C. 7:26E.
On June 2, 2008, the Department adopted new Remediation Standards rules at N.J.A.C. 7:26D. These rules were readopted without change on April 27, 2015. The soil remediation
standards contained in those rules were effective on June 2, 2008. The ground water and surface water remediation standards were previously effective at N.J.A.C. 7:26E-1.13.
On September 18, 2017, the Department updated the soil remediation standards for 19 contaminants, as listed in N.J.A.C. 7:26D, Appendix 1, Tables 1A and 1B. The updated soil
remediation standards reflect revisions to the toxicity information for these contaminants, as contained in the United States Environmental Protection Agency (USEPA) Integrated
Risk Information System (IRIS) database (see www.epa.gov/iris), on which the soil remediation standards are based.
On May 17, 2021, the Department adopted amended rules at N.J.A.C. 7:26D. Included in the amended rules are soil and soil leachate remediation standards for the migration to
ground water exposure pathway and indoor air remediation standards for the vapor intrusion exposure pathway. Also included is the replacement of direct contact soil remediation standards
with separate soil remediation standards for the inhalation exposure pathway and the ingestion-dermal exposure pathway. In addition, the rule amendments Expands the existing interim
remediation standard process to include soil and soil leachate for the migration to ground water exposure pathway, indoor air for the vapor intrusion exposure pathway, and ground water. Also, the existing process for
updating remediation standards has been expanded to include soil and soil leachate for the migration to ground water exposure pathway, indoor air for the vapor intrusion exposure pathway, and ground water. The existing
alternative remediation standards process has been expanded to include soil and soil leachate for the migration to ground water exposure pathway and indoor air for the vapor intrusion exposure pathway.
