1. Examine the designated uses and associated numeric water quality criteria that have been defined for surface waters in Texas (https-//texreg.90s.state.tx us/fids/201800575-5.pdf). Answer the following questions specifically for the Rio Grande Basin from the Lower Pecos River to the Rio Grande Tidal (Segment Nos. 23012310) a. What are the lowest and highest dissolved oxygen concentration criterion for these segments of the Rio Grande Basin? In which segments do these standards apply? b. What are the lowest and highest criteria for indicator bacteria concentrations in these segments of the Rio Grande Basin? In which segments do these standards apply? c. What are the designated uses for the segments identified in parts a and b ? d. How do the designated uses explain which segments have lower dissolved oxygen and higher bacteria concentration standards versus segments that have higher dissolved oxygen and lower bacteria concentration standards? Designated uses are abbreviated as follows: ALU - aquatic life use I-intermediate aquatic life use NCR-non-contact recreation AP - aquifer protection IS - industrial water supply PCR1 - primary contact AS - agricultural water supply L-limited aquatic life use recreation E-exceptional aquatic life use M - minimal aquatic life use PS - public water supply H - high aquatic life use N - navigation Rio Grande Basin Designated Uses and Numeric Criteria
