Update 2020-11-16: Better now, Withlacoochee River water quality 2020-11-14.
We’ve never seen anything quite like this.
Valdosta got 137,600 cfu/100 mL E. coli for Wednesday at GA 133 on the Withlacoochee River. That’s 137 times the Georgia Adopt-A-Stream alert limit of 1,000.
That’s far higher than the highest E. coli reading we’ve ever seen for the Withlacoochee River, which was the 39,000 Valdosta got on December 10, 2019, just after its infamous record spill. Which at least makes it unlikely that this contamination is coming from Valdosta.
Even the 85,600 Valdosta got for US 84 Wednesday is higher than that previous record at GA 133, and far above unprecedented for US 84. The previous US 84 record was 1,505 on April 1, after a big rain.
GA 133 is the same place Valdosta keeps finding very high E. coli and Fecal coliform, including 11,600 E. coli Friday a week ago. There has not been any rain. Which makes it very unlikely that this is runoff from farm animals.
Horrendous upstream, clean downstream

Yet Valdosta’s Wednesday downstream water quality results were all good, as were those by WWALS and Madison Health for Thursday.
According to the latest water quality results downstream of US 84, things look great for the Withlacoochee River this weekend. But I have to tell you I wouldn’t get in that water without more sampling.
I wish I could tell you what caused this, but so far I can only say a few things it’s not, and then speculate. Continue reading
