• Based on 7 Years of Data:– 2010 – December 1, 2001 – November 30, 2008– 2012 – December 1, 2003 – November 30, 2010
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)

CWA Requires State to Take Action to Restore Impaired Waters
(Arthur Talley)
• Additional Monitoring - is the impairment real?
• Use Attainability Analysis (UAA)- Are existing criteria and uses appropriate for water body?
• TMDL
• WPP
• Special Study
National Coastal Condition Assessment
• EPA National Aquatic Survey
• TCEQ and University of Houston
• 53 sites from Sabine Lake to Lower Laguna Madre
• 7 in Corpus Christi Bay and 2 in Nueces Bay
Sample Collection
• Water
• Sediment
• Bacteria
• Benthic Community
• Fish Tissue
