  1. Trends in Barton Springs • Nitrogen and other contaminants increasing over time in Barton Springs http://www.austintexas.gov/watershed_protection/publications/document.cfm?id=186332

  2. Nitrogen Balance for BSEA Report to be published soon on: http://www.austintexas.gov/watershed_protection/publications/default.cfm

  4. USGS Cooperative Project • Nitrogen increasing in surface water in the Contributing Zone • Isotopic signatures indicate source of nitrogen human, animal or both http://pubs.usgs.gov/sir/2011/5018/pdf/sir2011-5018.pdf

  5. Inventory of Growth, Wastewater • Wastewater disposal in Barton Springs Zone by OSSF, TLAP and centralized (CoA) collection http://www.austintexas.gov/watershed_protection/publications/document.cfm?id=186346

  6. TLAP Study Before/After new TLAP • Lazy 9 • Travis County MUD 4 Assess existing TLAP • Lost Creek MUD • Barton Creek West

  7. TLAP Study Parameters: • Field parameters (DO, Cond, pH, Temp) • Bacteria (E. coli) • Solids (TSS, VSS) • Nutrients (TP, OP, NO3, NH3, TKN, TOC) • Ions (alk, Br, Cl, F, SO4, Ca, B, Mg, Na, Sr, K) • Metals (Al, Ba, Cu, Fe, Pb, Zn, As, Sr) • Isotopes (Sr86/87, Del15N-NO3, Del18O-NO3)
