  1. Important Reminders • Sampling dates change in November & December. • Temperature change on the Percentile Range chart. • Data and paperwork coming in on time. • Take extra readings if the meter is still drifting. It’ll get cold soon. • When submitting data online, now use “Submit To Ken” button except in cases where there is more than one person entering data. Then save file between uses. • Carolyn Ross is the assistant to the Riverkeeper. She’ll be taking over most of the courier duties from the students. • Training today after the conference is over. It will be located across the street in room # 303. • Future of our current water quality meters

  3. Topics • This past year • Drought to Blackwater • Using percentiles for site specific standards • New graph feature at the website

  4. Web Resources Data Entry Data Retrieval • What sites are “hot”? • When are they “hot”? • Why?

  5. Dissolved Oxygen • Aquatic Sources • Atmosphere • Photosynthesis • Aquatic Sinks • Respiration • Animals • Microbes • Blackwater dissolved organic matter • Polluted runoff • Septage and sewage

  6. Questions • Which site has the lowest average oxygen level? • Do any geographic trends appear to be present? • Which sites have values below the WQS? • Which times of the year is oxygen lowest? • During which summer(s) were oxygen levels lowest?

  7. Is low DO “natural”? 293+71 180+47 230+54 212+37 112+20 151+65

  11. TDIN = nitrate + nitrite + ammonia SC DHEC mean value for 1990-1994: 0.26 mg/L SS for 2006 TDIN = 0.1 to 0.4 mg/L WQS based on US EPA recommendations & national ammonia criteria

  12. 3/08 to 6/09: conservative estimates

  13. Take home messages • Realizing the original intent • Trend analysis • Hot Spots and Illicit discharge detection • Timely • More stormwater pollution requirements • Less funding to SC DHEC Turbidity TDIN E. coli
