  1. 2009 Kentucky River Watershed Watch Results

  2. What and when? • Herbicidesin the Spring • 27 samples in May • Pathogensin the Summer • 128 Synoptic samples in July • 64 Follow-Up samples in Late July/Early August • Chemicals & Nutrientsin the Fall • 123 samples in September • NO Metalsin the Fall

  3. KRWW Sample #s (1999-2009)

  4. Where? • 176 sites throughout Kentucky River Basin • Mainly in Central Basin and North Fork Region • Poor site coverage in South and Middle Forks of Kentucky River, as well as Lower Kentucky Region

  5. Field Chemistry • Dissolved Oxygen • Aquatic Life Standard = 5 mg/L • 1% of stations had readings < 5 mg/L • pH • Aquatic Life Standard = 6 to 9 • 2 readings < 6 • K596-Eagle Creek, Owen Co. • K628-West Fork Silver Creek, Madison Co. • Temperature • None greater than Aquatic Life Std. of 31.7C

  6. HERBICIDES

  7. HERBICIDES Why monitored? • Potentially harmful to aquatic life and humans through drinking water Where are they coming from? • Runoff from agricultural and residential application How can we minimize their presence in our waterways? • Apply only as absolutely necessary, follow application instructions. • Maintain vegetation around and along waterbodies • Use recommended agricultural erosion control practices. • Properly dispose of herbicide containers (collection programs) • Do not dump leftover herbicide on ground, down sink, or down stormwater drains.

  8. 2009 Herbicide Parameters Sampled for 2 Herbicides in Spring 2009 • most likely time of year for herbicide application Triazines - highly persistent in soil - EPA Drinking Water Standard=3.0 micrograms/L - EPA Acute Aquatic Life = 350 micrograms/L • EPA Chronic Aquatic Life = 12 micrograms/L 2,4-D • Common herbicide to control broadleaf weeds • EPA drinking water standard (MCL) of 70 ppb

  9. Herbicide Results Atrazine • 6 detections • none exceeded water quality standards 2,4-D • No detections

  10. % Atrazine Detections (1999-2008) * Only once water quality standard exceedance at K501 (Eagle Creek in Owen County) in 2006 for Drinking Water Supply criteria.*

  11. PATHOGENS

  12. E. COLI Why monitored? • Can indicate presence of other pathogens that may cause illness or infections in people. Where are they coming from? • Failing septic systems, straightpipes, leaking sewage lines • Inadequately treated discharge from municipal sewage plants • Livestock (runoff from pasture or direct access to waterbody) How can we minimize their presence in our waterways? • Properly maintain septic systems. • Increase access to sewer systems. • Install fencing to keep livestock out of waterways. • Maintain vegetated buffers around waterbodies.

  13. Pathogen Parameters E. Coli • Swimming Standard of 240 cfu/100 ml (instantaneous) • Swimming Standard of 130 cfu/100ml (geometric mean of at least 5 samples in 30 days) • Standards apply during Recreation Season from May 1 to October 31

  14. Synoptic Pathogen Results (E. coli)59% > Swimming Standard23 sites exceeded maximum detection limit(2,420 cfu/100 ml in central KY, 4,840 in eastern KY) K626 – Potters ForkK50 – Benson CreekK52 – Benson CreekK94 – Lower Red RiverK95 – Red RiverK132 – West HickmanK184 – Wolf RunK191 – Otter CreekK305 – Town BranchK309 – McKecknie CreekK316 – North ElkhornK418 – West Hickman K462 – Cardinal RunK464 – Wolf RunK466 – Wolf RunK467 – Springs BranchK468 – Wolf RunK469 – Beacon Hill Clvt.K471 – Vaughn’s BranchK508 – Calloway CreekK517 – Springs BranchK595 – West HickmanK627 – Hayes Fork

  16. Follow-Up Pathogen Results84% > Swimming Standard

  17. 2007 Follow-Up Pathogen Sampling Sites > 5,000 cfu/100 ml

  18. DRY WET

  19. Pathogen Trends1999-2003 vs. 2004-2008 • Conducted statistical comparison of the two 5-year periods • Many sites with inadequate data • 3 sites withvery significant improvement: • K174 (South Elkhorn, Woodford Co.) • K198 (Ky River Pool 6, Woodford Co.) • K303 (Hickman Creek, Jessamine Co.) • 2 sites with very significant worsening: • K085 (Glenn’s Creek, Woodford Co.) • K096 (Greenwood Spring, Woodford Co.)

  20. Pathogen Trends1999-2003 vs. 2004-2008 Other sites with improvement: • K54 (McConnell Springs, Fayette Co.) • K105 (Blair Branch, Letcher Co.) • K156 (Fourmile Creek, Clark Co.) • K157 (Ky. River Boonesboro Beach, Clark Co.) • K199 (Ky. River, Mercer Co.) • K213 (Quicksand Creek, Breathitt Co.) • K245 (Muddy Creek, Madison Co.) • K249 (Muddy Creek, Madison Co.) • K301 (East Hickman Creek, Jessamine Co.)

  21. Pathogen Trends1999-2003 vs. 2004-2008 Other sites with worsening conditions: • K05 (Cane Run, Scott Co.) • K55 (Town Branch, Fayette Co.) • K57 (Beals Branch Spring, Woodford Co.) • K247 (Viney Creek, Madison Co.)

  22. NUTRIENTS

  23. NUTRIENTS Why monitored? • Lead to algal blooms, which consume oxygen as they decompose  bad for aquatic life • Cause taste and odor problems in drinking water • Can cause “Blue baby” disease (or methemoglobinemia) Where are they coming from? • agricultural and residential fertilizer application • sewage and manure runoff How can we minimize their presence in our waterways? • Only apply fertilizers as necessary • Properly maintain septic systems • Use recommended erosion control measures • Keep livestock out of waterways, properly manage manure • Maintain vegetated buffers around waterbodies

  24. Nutrient Parameters Nitrate (NO3-N) • Drinking Water Supply Std. = 10 mg/L • Aquatic Life Benchmark = 3.9 mg/L Total Phosphorus • KRWW Aquatic Life Std. = 0.5 mg/L Sulfate • Drinking Water Supply Std. = 250 mg/L

  25. Nitrate Results > 3.9 mg/L

  26. 3.9 mg/L

  27. Phosphorus Results > 0.5 mg/L 2007 High Phosphate Sites 2006 High Phosphorus Sites

  28. Sulfate Results > 250 mg/L

  29. 2006 High Sulfate Sites 2007 High Sulfate Sites

  30. Chemical Analysis Chlorides • Chlorine + Metals = Chloride Salts • Drinking Water Supply Std = 250 mg/L • Chronic Aquatic Life Std = 600 mg/L • Acute Aquatic Life Std = 1,200 mg/L Highest ‘09 Chloride Reading of 692 mg/L at K640 – Clark’s Run, Boyle Co.

  31.
