Laboratories certified to conduct water testing for private water systems

The private water system rules (Ohio Administrative Code Chapter 3701-28) require water samples collected from private water systems to be analyzed by laboratory certified by either the Ohio Department of Health (ODH) or the Ohio Environmental Protection Agency (OEPA) for system approval after new construction, alteration or repair. The department recommends that all water samples collected from private water systems for real estate transactions, or consumer information also be analyzed at a certified laboratory to ensure that proper procedures and water analysis methods are used to protect public health.
