Pierce County 2010 Surface Water Report Card

  1. 1. Pierce County Surface Water Management Water Health Report Card and Stormwater Monitoring ResultsCarla Vincent, Diane Klavano & Berl Eldridge
  2. 2. Monitoring Components• Water Quality National Pollutant Monitoring Discharge and• Biological Elimination System Monitoring (Aquatic (NPDES) – Municipal Insects) Stormwater• Annual Water Discharge Quality Report Card Monitoring
  3. 3. Water Quality Monitoring • Collect monthly water samples from 60+ streams each year • Analyze in field and lab • Tells current conditions • Helps identify where to focus resources & improvement efforts • Use data in annual WQ Report Card
  4. 4. Test for Conventional WQ Parameters• Phosphorus & Nitrogen• Total Suspended Solids (TSS)• Turbidity• Fecal coliform bacteria• Dissolved Oxygen (DO)• pH• Temperature• Conductivity
  5. 5. Nisqually Watershed WQ Sampling Sites
  6. 6. Stream Monitoring Stations (MS)in Nisqually Watershed• Horn Creek• Lacamas Creek• Lynch Creek• Ohop Creek• Tanwax Creek
  7. 7. Water Quality IndexA TOOL USED TO COMPARE & REPORTCOMPLEX WATER QUALITYMONITORING DATA
  8. 8. Pierce County Water Quality Index• Based on Ecology model• Uses eight parameters to calculate WQI: temperature, pH, FC, DO, TSS, turbidity, total phosphorus, total Kjeldahl nitrogen
  9. 9. Ecology has a rating curve for each parameter –score based on where results are on curveRating for temperature, pH, FC, DO is based onstate standards required to maintain beneficialuses, such as recreation, drinking water, andaquatic habitat (WAC 173-201A):If no state standard, based on historic backgroundconditions in our region.
  10. 10. Steps:1. Convert each measurement to common scale;2. Aggregate these into single monthly score;3. Average twelve monthly scores
  11. 11. Results: Unitless number • ≥80 Met expectations ranging from 1 to 100 for water quality – lowest concern Higher number • 40 – 80 marginal indicates better concern water quality. • <40 Did not meet expectations – highest concern
  12. 12. Stream results www.piercecountywa.org/wqws Overall Score 41 = MODERATE Blue = Good pH, temperature, turbidity, total suspended solids Yellow = Moderate Fecal, phosphorus Red = Poor nitrogen Three years of data available – annual scores on chart
  13. 13. Benthic Index of Biotic Integrity (BIBI)Using Biological Indicators to Measure Stream Health
  14. 14.  Collect & count the number & type of bugs living in the bottom of the stream The number & type of bugs present indicate stream health
  15. 15. Benthic Macro invertebrates (bottom-dwelling) (visible to naked eye) (no backbones) Heptageniidae sp. Hydropsyche sp. Perlodidae sp. (Mayfly larva) (Caddis fly larva) (Stonefly larva)Great candidates for biological monitoring…
  16. 16. Good Indicators of Water Quality• Limited migration patterns–good indicators of local conditions• Indicate effects of human impacts• Easy to sample• Many types, can classify by sensitivity to pollutants
  17. 17. The Tolerance Index (0 – 10)0 10most pollution sensitive most pollution tolerante.g. Stoneflies e.g. Midges & LeechesRequire high DO, clear Contain hemoglobin, toleratewater, rocky cobble lower DO, prefer soft substrate,substrate less sensitive to toxins
  18. 18. Macro invertebrate Sampling: The Basics• Site selection & assessment – subset of sites sampled annually• Organism collection and preservation – Standardize habitat type – Standardize sampling method – Surber sampler• Identification (Done in the lab) – Sample size – Fixed-count subsamples vs. “whole samples”• Calculation (Done by the lab) – Select metrics – Calculate IBI score (0-50) – Compare to reference score
  19. 19. BIBI Results www.pugetstreambenthos.org Repository of data from many jurisdictions in Puget Sound – look underPierce County - Watershed Health Monitoring
  20. 20. Nisqually Watershed BIBI Scores – From Pugetsoundbenthos.org
  21. 21. www.piercecountywa.org/wqws
  22. 22. Pierce County Surface Water Report Card• Assigns “grades” to 30+ streams in Pierce County where both WQI and BIBI data are available• Grades are based on average of WQI and BIBI, adjusted if on Clean Water Act 303(d) list of impaired waters
  23. 23. Report Card Stream Grades• Initial stream grade = Average of WQI and BIBI (adjusted to 0-100 scale)• Reduced 1/3 grade for each factor on 303(d) list• Often more than one factor that drives grade down.
  24. 24. What Drives Grades Down (Examples)• Fennel Creek (upper & lower) – P & N,• Diru Creek – P & N, fecal, BIBI is “poor”• Rody Creek - P, BIBI is “poor”• Swan Creek – P & N, fecal, pH, 303(d) listing
  25. 25. 2010 Grades – Nisqually WatershedHorn C-Lacamas C+Lynch BOhop C+Tanwax C Grades are FAIR to GOOD
  26. 26. 2010 Monitored Lakes Thanks to the City of Lakewood Volunteer Lake Monitoring Program, Pierce Stream Team, UW-Tacoma, & Tacoma Pierce County Health Dept (SWM grant funded)
  27. 27. Lake Health ParametersFinal lake grade is average of a number of grades:
  28. 28. National Pollutant Discharge Elimination System(NPDES) – Phase 1 Municipal Stormwater Permit • Part of federal Clean Water Act • Administered by Ecology • Annual Report due March 30 each year
