Current through Register Vol. 56, No. 24, December 18, 2024

Section 7:10-12.30 - Water quality analysis and treatment

(a) Upon completion of construction of a water system, the owner of a public noncommunity or nonpublic water system shall sample and analyze the microbiological quality of the raw water from the system and submit a copy of the results of the analysis to the administrative authority.

1. If the water does not meet the microbiological requirements of the State primary drinking water regulations at N.J.A.C. 7:10-5, the owner shall disinfect the water in accordance with N.J.A.C. 7:10-12.32.

2. Regardless of the raw water microbiological quality, the owner of a nonpublic water system or public noncommunity water system that uses a spring or surface water source shall disinfect the water in accordance with N.J.A.C. 7:10-12.32.

3. Microbiological quality shall be determined by analysis for total coliform. If the sample is total coliform positive, the total coliform positive culture medium must be analyzed to determine if E. coli are present. Analysis shall be conducted in accordance with N.J.A.C. 7:18.

(b) Upon completion of construction of a water system, the owner of a public noncommunity water system shall sample and analyze the raw water from the system for inorganics, volatile organic compounds (VOCs), the SOCs 1,2,3-trichloropropane, ethylene dibromide, 1,2-dibromo-3-chloropropane, the per- and polyfluoroalkyl substances perfluorononanoic acid (PFNA), perfluorooctanoic acid (PFOA), perfluorooctanesulfonic acid (PFOS), and radionuclides in accordance with N.J.A.C. 7:10-5 and for secondary contaminants in accordance with N.J.A.C. 7:10-7. If the system uses a surface water source, the administrative authority shall require the system owner to sample and analyze the water for disinfection byproducts and pesticides regulated pursuant to N.J.A.C. 7:10-5.

(c) Upon completion of construction of a water system, the owner of a nonpublic water system shall sample and analyze the raw water from the system for the parameters listed at (c)1 through 12 below. The administrative authority may require sampling and analysis for inorganic chemicals, volatile organic compounds, and/or radionuclides, as appropriate, based on the region and the aquifer in which the water source is located.

1. Nitrates;

2. Iron;

3. Manganese;

4. pH;

5. Lead;

6. All volatile organic compounds for which MCLs have been established under the State primary drinking water rules, N.J.A.C. 7:10-5;

7. Arsenic;

8. Gross alpha particle activity, determined using the 48 Hour Rapid Gross Alpha Test, in accordance with N.J.A.C. 7:18;

9. As of March 3, 2019, the synthetic organic compounds 1,2,3-trichloropropane, ethylene dibromide, and 1,2-dibromo-3-chloropropane;

10. As of December 1, 2021, the per- and polyfluoroalkyl substances PFNA, PFOA, and PFOS;

11. In addition to the parameters listed at (c)1 through 10 above, if the water system is located in Atlantic, Burlington, Camden, Cape May, Cumberland, Gloucester, Monmouth, Ocean, or Salem County, mercury; and

12. In addition to the parameters listed at (c)1 through 10 above, if the water system is located in Bergen, Essex, Hudson, Hunterdon, Mercer, Middlesex, Morris, Passaic, Somerset, Sussex, Union, or Warren County, uranium.

(d) The owner of the water system shall submit a copy of the results of the analyses conducted pursuant to (b) and (c) above to the administrative authority.

(e) Based on the results of the analyses submitted pursuant to (d) above, the administrative authority may require physical and chemical treatment of the water in accordance with N.J.A.C. 7:10-12.33.

(f) The owner of public noncommunity or nonpublic water system that uses a surface water source shall filter the water before it enters the distribution system using a filtration method approved by the Department. Public noncommunity water systems shall in addition meet the requirements of N.J.A.C. 7:10-9.

(g) All analyses required pursuant to this section shall be conducted at a certified laboratory, certified in accordance with N.J.A.C. 7:18 for the specific analytical method used.

(h) The administrative authority shall require the owner of a public noncommunity water system or nonpublic water system to provide treatment of the water when the water supply does not meet any of the maximum contaminant levels specified at N.J.A.C. 7:10-5.

(i) The administrative authority shall require the owner of a public noncommunity water system or nonpublic water system to provide treatment of the water when it determines that the exceedance of one or more of the standards established in the State Secondary Drinking Water Regulations, N.J.A.C. 7:10-7, causes adverse effects on consumers of that system's water.
