Well Testing


A satisfactory water test through this department is necessary for all new wells drilled in the Township. The NJ DEP requires all residences serviced by private well to be tested on transfer of title under the NJ Private Well Testing Act.  

UPDATE As of December 2021, the NJ Private Well Test Act requires PFOS (perfluorooctanesulfonic acid) testing, in addition to the other tests required under the NJ Private Well testing Act.  Please review the NJ DEP FAQ on PFOS testing for further information.  The State Department of Environmental Protection requires a well test on any sale of real property in the state; for more information on the "Private Well Testing Act" please view their well testing page or contact them at (866) 4PW-TEST

How Water is Delivered

Water is supplied to a home in one of two ways, either a public water supply or a private well. A public supply of water can be generated from wells or surface water, which is then treated in a water treatment plant. All public water in Roxbury is provided from wells. Products such as chlorine are then added to disinfect the water. There are two entities that supply water to Roxbury residents depending on where you live, either New Jersey American Water (a private utility) or Roxbury Township. Public water systems are regulated by the New Jersey Department of Environmental Protection and must follow the strict standards of the New Jersey Safe Drinking Water Act to assure the best quality of water is supplied to the public.

A private water supply is one that serves a single household. This water supply is generated from a well which pumps water up from the ground and into your house. A private well is regulated only by the Private Well Testing Act, which requires testing on the transfer of real estate only. It is up to the homeowner to have their well water tested periodically for impurities. There are some tests that the NJDEP and local health department recommend for home wells to help ensure safety of your water supply.
