Update 2022-07-03: PFAS testing, Withlacoochee River, Georgia and Florida 2022-06-30.
Update 2022-07-03: Madison Health Advisory, Withlacoochee River 2022-07-02.
Please avoid the Withlacoochee River this weekend, at least downstream from Hagan Bridge (GA 122). Try the Little River or the Alapaha, or the Suwannee upstream of the Withlacoochee River Confluence.
There was already contamination washed into the river by rain up to 4 inches in spots, according to Valdosta’s Wednesday results at US 41 and GA 133: 1,000 cfu/100 mL and 2,000 cfu/100 mL, where 1,000 is the alert level.
Then Valdosta had a major sewage spill.
Valdosta spilled 127,750 gallons from its Gornto Road Pump Station, slightly downstream of Sugar Creek, between US 41 and GA 133. That spill has not showed up in the GA-EPD Sewage Spills Report, because GA-EPD did not issue a report today, presumably because it is on vacation. But thanks to Valdosta Mayor Scott James Matheson for alerting WWALS, several of our members reported from the site during the spill.
WWALS testers Jacob and Michael Bachrach for yesterday samples got 11,333 at Knights Ferry Boat Ramp, downstream of Okapilco Creek, which drains cattle farms in Brooks County. You probably don’t want to get that water on you. I did, yesterday morning, and I washed with disinfectant.
So there are probably at least three sources of E. coli contamination right now:
- Unknown contamination sources upstream of US 41. Bad results there have happened many times before after big rains. Could be wild hogs, domestic horses, or something else.
- The Valdosta sewage spill.
- Cattle in Brooks County. Possibly plus wild hogs.
I plan to take a DNA test kit to State Line Boat Ramp tomorrow, which the contamination should have reached by then, and see what it detects.
Thanks to Elizabeth Brunner for her three GA 122 sites: Folsom Bridge on the Little River, Hagan Bridge on the Withlacoochee River, and Lakeland Boat Ramp on the Alapaha River.
Thanks to Michael and Jacob Bachrach for their Withlacoochee River sites: Knights Ferry, Nankin, and State Line Boat Ramps.
