Sampling Private Wells
The EPA Safe Drinking Water Act sets standards for drinking water quality for public water suppliers. Unlike residents served by public water systems, private well owners are responsible for ensuring that their own water is safe to drink.
Many factors can affect water quality such as natural impurities, land use, improper handling of chemicals and wastes, well conditions, etc. Your local health department can advise you about possible contaminants of concern for your area and provide guidance on parameters and recommended frequency of testing.
The EPA recommends a minimum annual testing for nitrates, coliform bacteria, total dissolved solids and pH as well as any other suspected contaminants. Testing is also recommended after any service is conducted on the well or replacement of pipes.
Drinking water, including bottled water, may reasonably be expected to contain small amounts of some contaminants. The presence of contaminants does not necessarily indicate that water poses a health risk. The EPA sets standards for approximately 90 contaminants in drinking water. Learn more about these standards, along with each contaminant's likely source and health effects on the EPA website.
