Water Quality Testing Training 2026-07-10

Here’s Heather Brasell’s account of this training:

Gretchen Quarterman trains everyone who tests water quality for the WWALS Watershed Coalition. She just retrained me — an annual requirement to ensure data quality. I test water quality at two sites — the outflow from the Alapaha Wastewater Treatment and at Sheboggy bridge where Highway 82 crosses the Alapaha River. I test for pH dissolved oxygen, conductivity and E.coli (biological). WWALS make the biological data available to the public so they know that their rivers are fishable and swimmable. I’ve been testing for several years and have never had water quality problems.

Photo 2: To test for E.coli (bacterial health concern), we add 1 ml of water onto a petrifilm and incubate it for 24 hours. The blue fuzzy colonies indicate E.coli bacteria (marked on the edge). The red colonies indicate other kinds of coliform bacteria, including ones that are not a health concern. To maintain data quality, we share photos like this with the group so someone else can confirm our counts.

Heather’s most report was July 1, 2026.

WWALS uses Georgia Adopt-A-Stream (AAS) methods, but we have testers in north Florida, as well. Maybe you’d like to be one!
