*In 1985, the Department amended the Surface Water Quality Standards (SWQS) at N.J.A.C. 7:9B-1.15 to upgrade certain surface waters of the State to Category One. While most of New Jersey's Category One waters were designated under these amendments, no specific basis for these upgrades was documented. Between 1985 and 2002, the Department designated more surface waters of the State as Category One. These upgrades were based on their value as trout production (FW2-TP) waters. Since 2002, the Department has promulgated several more amendments to the SWQS to upgrade the stream classification and antidegradation designations of additional waters of the State based on exceptional ecological significance or exceptional water supply significance. More information on Category One upgrades is available on the Department's Web site, along with maps of the stream classifications corresponding to each change to the stream classifications. Additional information on the Category One rulemaking actions, including the process for changing stream classifications is also available on the Web site.

*The 2008 GWQS rule amendments were adopted as a companion to the 2008 Water Quality Management Planning (WQMP) Rule amendments at N.J.A.C. 7:15. The basis and background document is a technical support document for the WQMP rules, entitled "Nitrate as a Surrogate for Assessing Impact of Development Using Individual Subsurface Sewage Disposal Systems on Ground Water Quality" (NJDEP, 2007). This document provides the scientific basis for the Department's proposal to establish nitrate as a surrogate for the large number of constituents in wastewater effluent discharged to ground water, which can occur in variable concentrations and are subject to numerous fate/transport responses after discharge, and the establishment of 2 mg/L as the statewide average existing ambient concentration of nitrate in ground water.

Interim Specific Ground Water Quality Criteria, PQLs, and GWQS for Class II Ground Water

Interim specific ground water quality criteria (ISGWQC), interim practical quantitation levels (IPQLs), and interim specific ground water quality standards (ISGWQS) were established by the Department between 2005 and 2015 for constituents not listed in Appendix Table 1 but for which sufficient information was available to determine the human health risk and derive an appropriate toxicity factor. These ISGWQC were established to assure that public health and the environment were protected in the most expeditious fashion once a concern was identified, usually in response to cleanup of a contaminated site. Interim practical quantitation levels (PQLs) were derived that represent the lowest concentration of a constituent that could be reliably achieved among certified laboratories within specified limits of precision and accuracy during routine laboratory operating conditions (i.e., the lowest quantifiable concentration). The higher of the interim ground water quality criterion and the interim PQL served as the constituent standard for each of these constituents in Class II until they were replaced with specific ground water quality standards in the adopted amendments published on January 16, 2018. All constituent standards for Class II ground water are as shown in Appendix Table 1 and Appendix Table 2 of the Ground Water Quality Standards.
