Drinking Water: Self-Reported Water Quality, Use of Filters, or Purchase of Bottled Water: Quality of Home Drinking Water, New Jersey, 2020

Indicator Report Data View Options

Why Is This Important?

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.

Definition

Percent of NJ residents self-reporting water quality by category, and use of filters or bottled water.

Data Notes

Survey Question: "How would you describe the quality of your water: excellent, very good, acceptable, or poor?".

Data Source

Behavioral Risk Factor Survey, Center for Health Statistics, New Jersey Department of Health

How the Measure is Calculated

  • Numerator:

    Number of people age 18 years and older self-reporting quality of water by category, and use of filters or bottled water.

  • Denominator:

    Total number of persons aged 18 and older interviewed during the same survey period.

Data Issues

Data from the New Jersey Behavioral Risk Factor Survey are intended to be representative of all non-institutionalized adult residents of New Jersey. Due to resource issues, however, adults with limited personal access to phone service or limited command of either English or Spanish are not represented. As with all surveys, also, some error results from nonresponse (e.g., refusal to participate in the survey or to answer specific questions), and faulty measurement (e.g., responses affected by social desirability or recall error). Data collection procedures intended to minimize such errors include the use of strict calling protocols, good questionnaire design, standardization of interviewer behavior, interviewer training, and frequent, on-site interviewer monitoring and supervision. Statistical weighting procedures are also used to minimize the potential impact of disproportionate representation of demographic subgroups defined in terms of age, sex, race, ethnicity, education level, marital status, home ownership, and county of residence.
