White Oak River Basin Basinwide Assessment Report Whole Effluent Toxicity Program 2005-2009
The Division of Water Quality’s Whole Effluent Toxicity Monitoring Program Acute and/or chronic toxicity tests are used to determine toxicity of discharges to sensitive aquatic species (usually fathead minnows or the water flea, Ceriodaphnia dubia). Results of these tests have been shown by researchers to be predictive of discharge effects to receiving stream populations. Many facilities are required to monitor whole effluent toxicity (WET) by their NPDES permit. Facilities without monitoring requirements may have their effluents evaluated for toxicity by DWQ’s Aquatic Toxicology Laboratory. If toxicity is detected, DWQ may include aquatic toxicity testing upon permit renewal. DWQ’s Aquatic Toxicology Unit maintains a compliance summary for all facilities required to perform tests and provides a monthly update of this information to regional offices and WQ administration. Ambient toxicity tests can be used to evaluate stream water quality relative to other stream sites and/or a point source discharge.
WET Monitoring in the White Oak River Basin: 2005-2009 Thirteen facility permits in the White Oak River basin require whole effluent toxicity (WET) monitoring (Figure 1 and Table 1). Of these thirteen, only 4 have permit limits. The other permits stipulate monitoring only with no limits associated with permit.
