H-GAC Texas Stream Team volunteers Valroy Maudlin and Tim Logan, using a test kit, measure the physical and chemical parameters of San Bernard River at two locations along the river. Valroy tests off his pier at CR 496, 1.6 miles upstream from the Churchill Bridge. Tim Logan tests off his dock at Rio Vista, 4.5 miles downstream from the Churchill Bridge. Both tests are done on the same day at the same time each month.

 

The test reports the pH level, salinity, temperature, dissolved oxygen and turbidity of the water. In March of this year, a bacterium enteroccocus test was added, conducted through a partnership with Galveston Bay Foundation (GBF). 

 

Starting now, both Valroy’s and Tim’s “Water Quality Monitoring Forms” will be shown for comparison as the data collected from the two locations can vary.

 

FOR citizen scientist Tom Ronayne measures the depth of the water at the Phillip's 66 dam on days when testing and sampling for bacteria is done at two locations further down the river. Rainstorm runoff and bacteria levels in the river are thought to be related, so these measurements are a rudimentary way of knowing the amount of runoff on the days bacteria is sampled.
