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.
NotesSurvey question: "What is the main source of your home water supply: a city, county or town water system; a small water system operated by a home association; a private well serving your home; other source; don't know ?" This question was not used in 2012. Annually, 5 - 8% of survey respondents did not know or refused to report the source of their home water supply.

Data Interpretation IssuesData 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 ServicesIf 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.
