LOINC description : 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

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

of contaminant removal varies by type of filtration system.;
