Explanation of Terms:

*  = 

Ground Water Quality Criteria and PQLs are expressed as ug/L unless otherwise noted. Table 1 criteria are all maximum values unless clearly indicated as a range for which the minimum value is to the left and the maximum value is to the right.

**  = 

revised via administrative change (see 39 N.J.R. 3538(a)).

PQL  = 

Practical Quantitation Level as defined in N.J.A.C. 7:9C-1.4

CASRN  = 

Chemical Abstracts System Registration Number

NA  = 

not available for this constituent.

a  = 

Asbestos criterion is measured in terms of fibers/L longer than 10 micrometers (f/L > 10 um)

ug  = 

micrograms, L = liter, f = fibers, CU= Standard Cobalt Units

b  = 

Odor Threshold Number, mg = milligrams, H = Hardness

(Total)

 = 

means the concentration of metal in an unfiltered sample following treatment with hot dilute mineral acid (as defined in "Methods for Chemical Analysis of Water & Wastes", EPA-600/4-79-020, March 1979) or other digestion defined by the analytical method. However samples that contain less than 1 nephelometric turbidity unit (NTU) and are properly preserved, may be directly analyzed without digestion.

m  =  Pursuant to prevailing Safe Drinking Water Act Regulations any positive result for fecal coliform is in violation of the MCL and is therefore an exceedance of the ground water quality standards.

Unless otherwise noted, all ground water quality criteria are measured in micrograms per liter ( ug/L), which is equivalent to parts per billion (ppb).

Compendium of Standards

The Department has developed an electronic compendium of standards for water and soil promulgated by the New Jersey Department of Environmental Protection. Included are Surface Water Quality Standards, N.J.A.C. 7:9B; Ground Water Quality Standards, N.J.A.C. 7:9C; Drinking Water Quality Standards, N.J.A.C. 7:10; and soil remediation standards from the Remediation Standards, N.J.A.C. 7:26D. The compendium includes the standards and information about the basis for the standards contained in the above referenced rules. The standards in these rules are used by the Department's regulatory programs to establish site-specific requirements in accordance with the appropriate regulations. Please refer to the official versions of these rules for the most accurate information about the standards currently in effect and how they are administered by the Department. Information on obtaining the official versions of Department rules is available on the Department's Web site at http://www.state.nj.us/dep/legal/get_rule.htm.
