Classified Water Bodies Are Assigned Designated Uses –Aquatic Life Exceptional High Intermediate Limited –Oyster Waters –Contact Recreation Primary Contact Secondary Contact 1 and 2 (New) Noncontact –Public Water Supply –Fish Consumption –General Use

Water Quality Criteria are Assigned to Designated Uses Aquatic Life –Dissolved Oxygen Public Water Supply –Chloride –Sulfate –TDS Recreation –Bacteria General Use –Water Temperature –pH –Ammonia –Nitrogen –Phosphorus Fish Consumption –Fish Tissue

Assessment Includes 2 Lists: –305(B) List Concerns –303(d) List Impairments

Concerns 305(b) List 20% of samples > criteria –Ammonia-Nitrogen –Nitrate+Nitrite –Orthophosphorus –Total phosphorus –Chlorophyll-a

Impairments 303(d) List Water bodies that do not meet the criteria for support of one or more of its beneficial uses

Impairments 303(d) List TDS, Chloride, Sulfate –Average > criteria (Public Water Supply Impairment) DO: grab samples and 24-Hr average –10% of samples < criteria (Aquatic Life Impairment) pH –10% of samples outside range (General Use Impairment) E. coli, Enterococcus –Geometric mean > criteria (Recreation use Impairment)
