Review Measure

Essential Measures are only those items that are critical to the collection of the Measure or are necessary for the interpretation of results. Essential Measures are integral to the Measure. Without such information the data collected would be incomplete and/or misleading.
An additional PhenX Measure that the user may find helpful based on the selection of a particular PhenX Measure. Related PhenX Measures can include additional Measures that are needed to calculate a Derived Variable (e.g., Weight and Height are needed to calculate BMI), Measures that are commonly used in presentations and publications to present the value of the chosen Measures (e.g., Height and Weight by Race and Ethnicity), Measures that are conceptually related to the chosen Measure (e.g., Current Educational Attainment is conceptually related to Annual Family Income and Arm Span is conceptually related to Height), Measures that are physiologically and/or biologically related to the chosen Measure (e.g., Stroke and Heart Disease). Related PhenX Measures are suggestions only.
The Collections are an alternative to the research domains for browsing the PhenX Measures. Measures that are related by a specific topic are grouped together.

Measure: Water Source   #060200


Questions asking about the drinking water source and use of water filtration systems in the respondent’s home.


Some water sources contain contaminants and disinfection byproducts that may adversely affect a person’s health. Public (municipal) water systems receive disinfection and other treatments that may remove some contaminants to comply with the Environmental Protection Agency (EPA) drinking water regulations. Private wells are not regulated by EPA and can contain high levels of potentially dangerous chemicals such as arsenic, nitrate, and pesticides. The likelihood that a private well has contaminants differs by well depth, well construction, location, and characteristics of the soil and aquifer. Additional information about the type of water filtration system used by the household is also valuable because the effectiveness of contaminant removal varies by type of filtration system.
