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.
2006 Herbicide Parameters Sampled for 2 herbicides in Spring 2006 • most likely time of year for herbicide application Triazines • highly persistent in soil • EPA standard of 3.0 micrograms /L for drinking water • 350 micrograms/L for acute aquatic life criteria • 12 micrograms/L for chronic aquatic life criteria Metolachlor • highly persistent in water • unregulated by EPA
Herbicide Results Triazines NOT detected Metolachlor found at 5 sites, the greatest being: K558 (Mock’s Creek) – 0.08 micrograms/liter (laboratory MCL was 0.08 ug/L for Metolachlor)
2007 Herbicide Sampling Results 2006 Herbicide Detections K501 – Eagle Creek Herbicides detected Herbicide sampling site
FECAL COLIFORM / 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
Pathogen Parameters Fecal Coliform • Swimming Standard of 400 cfu/100 ml (instantaneous) E. Coli • Swimming Standard of 240 cfu/100 ml (instantaneous) Atypical/Typical Coliform Ratio • Ratio between 0 and 2 raw, human sewage • Ratio between 2 and 4 fresh, human/ag • Ratio between 5 and 10 indirect, ag • Ratio between 10 and 20 indirect, urban • Ratio greater than 20 aged, human/ag
Synoptic Pathogen Results (Fecal coliform)52%> Swimming Std.
Synoptic Pathogen Sampling Sites > 5,000 cfu/100 ml 2006 Synoptic Pathogen Sampling Results > 5,000 cfu/100 ml
Follow-Up Pathogen Results (Fecal coliform)96% > Swimming Std.
Focused Pathogen Sampling • Cane Run, Scott Co. (2 sites) • Glenn’s Creek, Woodford Co. (4 sites) • White Oak Creek, Garrard Co. (2 sites) • Herrington Lake (6 sites) • North Fork Ky. River, Letcher Co. (13 sites)
2007 Focused Pathogen Sampling Sites Cane Run White Oak Creek Glenn’s Creek Herrington Lake North Fork Kentucky River
Focused Pathogen Results Cane Run – geometric mean for 2/2 sites > PCR std. Glenn’s Creek – 4/4 sites > std. White Oak Creek – 1/2 sites > std. Herrington Lake – 0/6 sites > std. North Fork Ky River – 11/13 sites > std. PCR = primary contact recreation (swimming/wading)
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
Nutrient Parameters Nitrate (NO3-N) • Drinking Water Supply Std. = 10 mg/L Total Phosphorus • Unofficial KRWW Aquatic Life Std. = 0.5 mg/L Sulfate • Drinking Water Supply Std. = 250 mg/L
