Introduction to Remediation Standards<\/strong><\/p>\n May 2021<\/strong><\/p>\n These rules implement the provisions of the Brownfield and Contaminated Site Remediation Act<\/a> [pdf]<\/span>, 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<\/a> [pdf]<\/span>, N.J.A.C. 7:26E.<\/p>\n 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.<\/p>\n 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 EPA Integrated Risk Information System<\/a>), on which the soil remediation standards are based.<\/p>\n 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.<\/p>\n Remediation Standards<\/strong><\/p>\n Interim Remediation Standards<\/strong><\/p>\n Remediation Standards Comparison Tables<\/strong><\/p>\n <\/a><\/p>\n Phase In\/Order of Magnitude Guidance<\/strong><\/p>\n The Department has issued the following guidance documents to assist remediating parties in complying with the amended ground water remediation standards adopted or developed on February 3, 2025:<\/p>\n The Department issued the following guidance documents to help remediating parties in complying with the Remediation Standards rules at N.J.A.C. 7:26D updated on August 4, 2025:<\/p>\n <\/a><\/p>\n Basis and Background Documents<\/strong><\/p>\n Guidance Documents<\/strong><\/p>\n Calculators<\/strong><\/p>\n The Soil and Soil Leachate Migration to Ground Water Exposure Pathway Calculator<\/p>\n This includes the following calculators:<\/p>\n Soil Ingestion-Dermal Exposure Pathway Calculator<\/p>\n Soil Inhalation Exposure Pathway Calculator<\/p>\n Vapor Intrusion Exposure Pathway Calculator<\/p>\n The Extractable Petroleum Hydrocarbon Ingestion-Dermal Exposure Pathway Calculator:<\/p>\n This includes the following calculators:<\/p>\n Tips for Using NJDEP Remediation Standards Calculators<\/strong><\/p>\n Extractable Petroleum Hydrocarbon Information<\/strong><\/p>\n Chromium<\/strong><\/p>\n Alternative or Interim Remediation Standards and or Screening Level Application Forms<\/strong><\/p>\n NOTE: The following attainment and compliance documents which pertain specifically to the migration to ground water exposure pathway may be accessed at CSRR Guidance Library<\/a><\/strong><\/p>\n Remediation Standards Archive page<\/strong><\/a>[\/vc_column_text][\/vc_column][vc_column offset=”vc_col-lg-3 vc_col-md-3″ el_class=”order-1 swap-on-mobile”][vc_column_text]<\/p>\n Notes<\/strong>\n
