Health Indicator Report of Private Well Usage: Self-Reported as Main Source of Drinking Water

Water is used for many purposes including drinking, cooking, bathing, cleaning, and recreation. Because water use is so common in daily life, there are many opportunities for contaminated water to impact people. New Jersey has over 600 community water systems which provide drinking water to approximately 87% of the State's population. However, about 13 percent of New Jersey residents obtain their drinking water from private wells.

Self-Reported Testing of Private Well Used for Drinking Water Tested for Contaminants within last 2 Years, by County, 2014


Notes

Survey question: "Has your well water ever been tested for contaminants in the last 2 years: yes; no; don't know/not sure ?" This question was only asked to individuals who reported that their main water source was a private well. **Data are not shown for Essex, Hudson or Union Counties due to very low usage of private wells in these counties.

Data Interpretation Issues

Data from the New Jersey Behavioral Risk Factor Survey are intended to represent non-institutionalized adults in households with telephones. Data are collected using a random sample of all possible telephone numbers throughout New Jersey. Prior to analysis, data are weighted to represent the population distribution of adults by age, sex, and "race"/ethnicity. As with all surveys, however, some residual bias may result from non-response (e.g., refusal to participate in the survey or to answer specific questions) and measurement error (e.g., social desirability or recall). Attempts are made to minimize such error by use of a strict calling protocol (up to 15 calls are made to reach each household), good questionnaire design, standardization of interviewer behavior, interviewer training, and frequent, on-site interviewer monitoring and supervision.

How Are We Doing?

If you are a New Jersey resident who uses their own source of drinking water, like a well, cistern, or spring, you are responsible for protecting and monitoring your water supply. It is essential that you test your water periodically, and maintain your well. There are no federal or state regulations assuring the quality of the water consumed by NJ residents who obtain their drinking water from private wells. The New Jersey Private Well Testing Act (PWTA) assures that the purchasers and lessees of properties served by private potable wells are aware of the quality of their drinking water source prior to the sale or lease of a home or business. Sampling and testing must be conducted by certified laboratories.

Available Services

If your drinking water comes from a private well, you are responsible for testing. The NJDEP recommends that you use a laboratory that is NJDEP-certified. You can call the NJDEP Office of Quality Assurance at (609) 292-3950 for information on laboratories certified to test drinking water or look for the information online at: [https://www13.state.nj.us/DataMiner] using the "Search by Category" option, select "Certified Laboratories", and search for "Certified Drinking Water Labs", "PWTA Laboratories Certified for Sampling", or "Laboratories Certified by Parameter". Testing is required for sale of residential real estate when a private well is the source of drinking water.
