The Environmental Health Division maintains a water bacteria testing laboratory for public water supplies. The laboratory is New York State and Environmental Protection Agency (EPA) approved and certified to test potable (drinking) water and non-potable (bathing beach) water for indicator bacteria (total coliform and E.coli).
The laboratory only accepts samples from public water supplies, see Public Drinking Water section below.
Samples are normally accepted Monday - Wednesday, however, the annual holiday schedule may affect the normal acceptance schedule. Call (716)753-4481 to verify holiday week schedules.
Private water samples collected by individuals other than Environmental Health staff are not accepted. If you'd like to schedule a service request for a staff member to collect a water sample, please click here to complete the request form.
The Environmental Health Division provides this mandatory service to private property owners for a fee. When any type of property in Chautauqua County, served by a private water supply and an onsite wastewater treatment system (OWTS), is sold or transferred, the Environmental Health Division must evaluate the water supply and the OWTS.
The Environmental Health Division may be able to provide technical assistance to property owners regarding their private water supply. Private water supply sources include dug, driven, or drilled wells, along with less common sources such as ponds and springs.
The primary purpose of Environmental Health's Water Supply Program is to ensure the safety of county public water supplies. There are three general types of public water supplies: community, transient non-community, and non-transient non-community. Community water supply sources include wells, springs, lakes, or other surface water sources.
The Environmental Health Division regulates the private sewage/wastewater system program. Inspectors oversee the design and installation of new onsite wastewater treatment systems (OWTS), as well as, corrections to existing systems to ensure installation meets the standards outlined in Article IV of the Sanitary Code of the Chautauqua County Health District and New York State Code Part 75.
