Need more river testing and more types of testing 2025-09-13

E. coli is the canary in the coal mine for other contaminants in waterways.

For years WWALS has been asking the state of Florida to test frequently in many places on all rivers, to very little response FDEP did do some testing for chemical and biological tracers, including DNA tests, after Valdosta’s huge December 2019 spill, but that petered out. While FDEP was doing that, those results helped identify another source of contamination that was not Valdosta.

WWALS did test the Withlacoochee River for PFAS forever chemicals and round some, although much less than many other rivers, and no higher below the outfall of Valdosta’s Withlacoochee Wastewater Treatment Plant or PCA’s package plant.

FDEP continued with quarterly tests for a while, and put at least its fecal bacteria results online. But it stopped doing that last year.

The 2020 GA-EPD Consent Order on Valdosta required bacterial testing of the Withlacoochee River over 40 river miles three times a week, for four years. Once those four years were up, Valdosta dropped back to two locaitons once a week.

USGS ceased financial support for nitrate and pH monitoring in eight Florida springs this year. It is not clear whether SRWMD picked up the slack.

We need more testing, not less.

Treated wastewater still has PFAS and other contaminants, as Joe Squiteri of Lee, Florida, pointed out in the recent meeting of the Florida Rivers Task Force with the City of Valdosta. Continue reading

Nitrate monitoring and mining on SRWMD land –Suwannee Riverkeeper to SRWMD Board 2025-07-08

Update 2025-07-21: PFAS in sewage effluent used to restore wetlands 2025-07-18.

I did get answers from the Suwannee River Water Management District (SRWMD) about nitrate testing for springs, but no response about the Chemours application to mine on SRWMD land in Bradford County in the Santa Fe River Basin, using mineral rights retained by Rayonier.

Surprisingly, nobody showed up to speak at the recent SRWMD Board meeting in item 6. Public Comment. See SRWMD’s YouTube video at 15:28.

Revised Hydrogeologic Framework of the Floridan Aquifer System 2016-03

Salt water intrusion inland is worse than you think, including the “Apalachicola salinity feature” up to the GA-FL line and east through Lowndes County, with a special additional brackish Valdosta feature. Central north Florida is an island of fresh groundwater surrounded by entire saline Florida coast around from Alabama plus across to Brunswick, GA, then again from Savannah up past Charleston. South of Lakeland, FL the map is all red for saline.

Videos, Valdosta Wastewater and Flood Prevention 2016-10-27

The crowd was very attentive to every word about wastewater and flood prevention, with officials from the City of Valdosta presenting in the first of a new quarterly WWALS speaker series. If you didn’t come, you can see and hear in these videos Henry Hicks about wastewater, Emily Davenport about flood prevention, Tim Carroll about solar power, and Sementha Mathews about how to get more information from Valdosta. WWALS Treasurer and acting Executive Director Gretchen Quarterman opened and closed the meeting.

Each talk had many small but important stories, so we will probably blog more posts about those. Meanwhile, here are the videos: see for yourself! Continue reading

Valdosta wastewater and flood prevention public meeting by WWALS 2016-10-27
