Morris48.2 95% Confidence Interval(32.5 - 64.0)Description of the Confidence IntervalThe confidence interval indicates the range of probable true values for the level of risk in the community.
A value of "NA" (Not Available) will appear if the confidence interval was not published with the NJSHAD indicator data for this measure.

Morris Compared to State
Description of Gauge
Description of the GaugeThis graphic is based on the county data to the left. It compares the county value of this indicator to the state overall value.
The county value is considered statistically significantly different from the state value if the state value is outside the range of the county's 95% confidence interval. If the county's data or 95% confidence interval information is not available, a blank gauge image will be displayed with the message, "missing information."NOTE: The labels used on the gauge graphic are meant to describe the county's status in plain language. The placement of the gauge needle is based solely on the statistical difference between the county and state values. When selecting priority health issues to work on, a county should take into account additional factors such as how much improvement could be made, the U.S. value, the statistical stability of the county number, the severity of the health condition, and whether the difference is clinically significant.
- Excellent = The county's value on this indicator is BETTER than the state value, and the difference IS statistically significant.
- Watch = The county's value is BETTER than state value, but the difference IS NOT statistically significant.
- Improvement Needed = The county's value on this indicator is WORSE than the state value, but the difference IS NOT statistically significant.
- Reason for Concern = The county's value on this indicator is WORSE than the state value, and the difference IS statistically significant.
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.
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.
NoteSurvey 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 Bergen, Essex, Hudson, Middlesex, or Union Counties due to very low usage of private wells in these counties.
