1 2009 Kentucky River Watershed Watch Results

2 What and when? Herbicides in the Spring – –27 samples in May Pathogens in the Summer – –128 Synoptic samples in July – –64 Follow-Up samples in Late July/Early August Chemicals & Nutrients in the Fall – –123 samples in September NO Metals in 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

6 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 31.7C

7 HERBICIDES

8 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.

9 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

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

11

12 % Atrazine Detections (1999-2008) * Only once water quality standard exceedance at K501 (Eagle Creek in Owen County) in 2006 for Drinking Water Supply criteria.*

13 PATHOGENS

14 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.

15 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

16 Synoptic Pathogen Results (E. coli) 59% > Swimming Standard 23 sites exceeded maximum detection limit ( 2,420 cfu/100 ml in central KY, 4,840 in eastern KY) K626 – Potters Fork K50 – Benson Creek K52 – Benson Creek K94 – Lower Red River K95 – Red River K132 – West Hickman K184 – Wolf Run K191 – Otter Creek K305 – Town Branch K309 – McKecknie Creek K316 – North Elkhorn K418 – West Hickman K462 – Cardinal Run K464 – Wolf Run K466 – Wolf Run K467 – Springs Branch K468 – Wolf Run K469 – Beacon Hill Clvt. K471 – Vaughns Branch K508 – Calloway Creek K517 – Springs Branch K595 – West Hickman K627 – Hayes Fork

17 2006 Synoptic Pathogen Sampling Results > 5,000 cfu/100 ml Synoptic Pathogen Sampling Sites > 5,000 cfu/100 ml

18 Follow-Up Pathogen Results 84% > Swimming Standard

19 2007 Follow-Up Pathogen Sampling Sites > 5,000 cfu/100 ml

21 Pathogen Trends 1999-2003 vs. 2004-2008 Conducted statistical comparison of the two 5- year periods Many sites with inadequate data 3 sites with very 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 (Glenns Creek, Woodford Co.) – –K096 (Greenwood Spring, Woodford Co.)

22 Pathogen Trends 1999-2003 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.)

23 Pathogen Trends 1999-2003 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.)

24 NUTRIENTS

25 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

29 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
