Comparison: State vs. Federal
• Rules. Tennessee follows the federal Clean Water Act in requiring dischargers to conduct biological monitoring on a case-by-case basis at the discretion of the Tennessee Department of Environment and Conservation (TDEC). A facility's National Pollutant Discharge Elimination System (NPDES) general permit will also explain what types of monitoring are required for a facility. See the national section BIOASSAYS/BIOMONITORING for further information about the federal requirements.
The state has also established regulations that laboratories testing public water supplies must be certified by Tennessee in order to properly analyze and report testing results.
• Administration and enforcement. TDEC's Division of Water Resources is responsible for implementing all water quality monitoring programs in Tennessee.
The DOH and TDEC's Division of Water Resources share responsibility for administering the laboratory certification program for testing drinking water in Tennessee.
