Private Well Testing Act
Regulations 7:9E - Effective Sept. 16, 2002 - Updated Sept. 4, 2018
Garden State Laboratories is pleased to provide sampling and analytical services in accordance with New Jersey's Private Well Testing Act, No. A1306. Signed into law in March 2001, it became effective on September 14, 2002. This law mandates that whenever a property with a private well is sold or leased, certain drinking water tests must be performed and the results given to both the buyer and seller prior to closing, or the lessor and lessee. Results must also be submitted electronically to the New Jersey Department of Environmental Protection (NJDEP).
Sample results that exceed State standards will be forwarded by the NJDEP to the local health authority. The local health authority has the option to notify other properties in the area suggesting or recommending testing for these parameter(s). The specific address or location of the private well that exceeded standards shall not be identified in the notice or by any other means or in any other manner. The testing requirement for rental properties must have been completed by March 14, 2004 and every 5 years thereafter.
The NJDEP has set up a web site for the PWTA. The NJDEP finalized initial PWTA regulations, effective Sept. 16, 2002. On Sept. 4, 2018 the 7:9E-2.1 Regulations were updated to make arsenic and gross alpha particle activity testing State-wide. Uranium is now required in central and northern counties. In addition, 3 synthetic organic compounds; 1,2,3-trichloropropane, ethylene dibromide, and 1,2-dibromo-3-chloropropane will be required to be tested State-wide starting March 3, 2019. Links to the PWTA statute, regulations and a PWTA frequently asked questions page are on the NJDEP's PWTA web site.
Garden State Laboratories is TNI (The NELAC Institute) accredited by the NJDEP. This is the highest level of laboratory certification available. With field samplers covering the State of New Jersey we can provide sampling and analysis to meet the NJDEP's stringent requirements.
The laboratory was founded in 1943 when we initially performed bacteriological and chemical food and water testing. Over the years Garden State Labs has instituted a wide variety of bacteriological and chemical analyses, including minerals, metals, and volatile organic compounds.
