Part 2: Private Well Testing Act Test Results
During the first four and half years of the Private Well Testing Act Program September 2002 through April 2007), a total of 51,028 individual wells were sampled. The number of wells sampled in each county ranged from 1 well in Hudson County to 5681 wells in Sussex County (see Figure 1).

Number of Wells
Although the number of wells sampled for the PWTA represents the number of private wells involved in real estate sales transactions and rentals, over time the water quality from these wells should give us a complete picture of the water quality of in the state. It is estimated that there are about 400,000 private wells in New Jersey. Based on that number the PWTA program has data for approximately 13 percent of New Jersey’s private wells. The map in Figure 2 shows the locations of the wells that have been tested in the first four and half years.
