Health Indicator Report of Drinking Water: Self-Reported Water Quality, Use of Filters, or Purchase of Bottled 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: "How would you describe the quality of your water: excellent, very good, acceptable, or poor?".
Data SourceBehavioral Risk Factor Survey, Center for Health Statistics, New Jersey Department of Health, [http://www.state.nj.us/health/chs/njbrfs/]
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.

What Is Being Done?Public water suppliers are required by law to monitor for regulated contaminants based on type of water system and water source, and ensure the water meets state and federal Maximum Contaminant Levels (MCLs). The test results are sent to the NJ Department of Environmental Protection (NJDEP). If the level of any regulated contaminant is above the MCL, additional samples are taken to confirm that a problem exists. The supplier of that water is then required to eliminate the problem by changing to another water source or by improving water treatment. The NJDEP inspects community drinking water systems and evaluates their monitoring reports for compliance with the standards. Noncompliance with a standard can result in a violation. NJDEP works with systems to ensure they notify the public and return to compliance.
Available ServicesIf your drinking water comes from a community water system: You can get the most recent test results for your water system by contacting your water supplier or by accessing Drinking WaterWatch available here: [https://www9.state.nj.us/DEP_WaterWatch_public/index.jsp] The NJDEP Bureau of Safe Drinking Water is responsible for ensuring public water systems satisfy federal and state drinking water standards and the other provisions of the Federal and State Safe Drinking Water Acts. Contact the NJDEP Bureau of Safe Drinking Water Technical Assistance at (609) 292-5550, or [http://www.nj.gov/dep/watersupply/] 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 obtain 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". Well testing is required prior to the sale of residential real estate when a private well is the source of drinking water.
