2 ANRA Environmental Laboratory The Angelina & Neches River Authority (ANRA) operates an environmental laboratory accredited by the National Environmental Laboratory Accreditation Program (NELAP) through the Texas Commission on Environmental Quality (TCEQ). Samples collected by SFASU are submitted to the ANRA Environmental Laboratory for analysis of the following parameters: Ammonia Nitrogen Nitrate + Nitrite Nitrogen Dissolved Ortho Phosphorus Total Phosphorus Total Suspended Solids (TSS) E. coli. 2

3 Preliminary Analysis Results Laboratory data presented represents results to date for the Attoyac Watershed Protection Plan Project as analyzed by the ANRA Environmental Laboratory. One set of data has been submitted to TCEQ s Surface Water Quality Monitoring Information System (SWQMIS) database. 3

4 Surface Water Quality Standards Analytical results were compared to TCEQ s water quality standards to determine if values exceeded criteria. Attoyac Bayou (Segment 612) has established criteria. For unclassified segments, the criteria for 612 were used. The following criteria were used: Ammonia N.33 mg/l Nitrate+Nitrite N 1.95 mg/l Orthophosphorus.37 mg/l Total Phosphorus.69 mg/l E. coli (geometric mean) 126 cfu/1 ml 4

25 Interim Guidance for Routine Surface Water Quality Monitoring During Extended Drought Document issued by TCEQ to address routine surface water quality monitoring activities during periods of extended drought. 25

26 Interim Guidance for Routine Surface Water Quality Monitoring During Extended Drought Collect and report data according to the following guidelines: Schedule and travel to monitoring sites as you would normally do to meet routine commitments Not necessary if you can reliably determine that the scheduled monitoring site is dry (record a value of 6 for Flow Severity and Days Since Last Significant Precipitation) Photo document flow conditions, even if the monitoring station is dry If water is present at the stream monitoring sight within ± 4 meters of the established monitoring station, and minimum size meets the required dimensions (see below), go ahead and collect routine monitoring data A pool is defined as anything 1 meters in length and.4 meters in depth The total length of the reach upstream/downstream of a sample station to determine pool coverage should be between 5 and 8 meters. A physical measurement is the preferred method for determining percent pool coverage, but a visual estimate can also be made. 26

27 Interim Guidance for Routine Surface Water Quality Monitoring During Extended Drought Report the following pool characteristics: Maximum pool width (meters) Maximum pool depth (meters) Pool length in meters (meters) Percent pool coverage in 5 meter reach Report location of where the main pool is in relation to the bridge crossing and any other pertinent details such as presence of fish, mussels, or other wildlife. Photographs upstream and downstream of the bridge and of the main pool are encouraged. Even when the monitoring site is dry, create a sample event in the TCEQ s Surface Water Quality Monitoring Information System (SWQMIS) database for field data. 27

28 Interim Guidance for Routine Surface Water Quality Monitoring During Extended Drought The minimum data required to report is Flow Severity and Days Since Last Significant Precipitation If the stream channel contains water, but there is no flow, report 1 for Flow Severity, and a flow value of cfs. If the stream contains no water, report a value of 6 for Flow Severity, and do not report a result for flow. Report the actual number of Days Since Last Significant Precipitation, even if the value is greater than 7. The statewide outlier maximum for this parameter has now been set to detect outliers at 75 days. Note comments indicating drought condition 28
