No, the test cannot be reused. The Blue-Green Algae BART test includes the bottle, geo-cloth and dehydrated nutrients. If present, the algae will grow on the cloth inside the sample bottle and using the dehydrated nutrients. One used, the test should be safely disposed of with a dedicated microwave or an autoclave.
The test should be observed a minimum of 3 times a week for 24 days.
In the documents tab, there is a document that shows the advanced test information. The amount of growth and color determines the type of bacteria growing. Cyanobacteria is indicated by dark-green, blue-green, or black growths at the water line.
The potential algae population can be determined by the number of days it takes to react. Under the documents tab, the pdf explains the determination for each number of days. The quicker the reaction, the higher the potential population.

A few years after Ohio became a state in 1803, George Harner arrived in Greene County with a land deed signed by then-President Thomas Jefferson and Secretary of State James Madison. The homestead was largely old forest and wetlands and also included a fen-fed stream—the Beaver Creek.
As was the case with much of the Ohio Territory, the forests eventually gave way to land clearing and grain farming. Harner’s descendants, including his son John and John’s wife, Sarah Koogler, continued to work the rich soil for many years to follow.
Much of the original property and surrounding land has fallen prey to urban sprawl.Read More
Each fall in Puget Sound, coho salmon leave the salt water and swim up freshwater streams. They head upstream to spawn: lay their eggs and die.
Death is always the end of this journey for coho salmon, but in streams now running through urban areas, stormwater runoff kills them before they can spawn.
This phenomenon, called Urban Runoff Mortality Syndrome, can kill up to 70-90% of coho salmon in an affected area.
“‘Woah’ is a pretty common response,” said Kathy Peter, a research scientist formerly at University of Washington Tacoma and the Center for Urban Waters.
This phenomenon adds pressure to the Puget Sound population, already considered a species of concern by the United States Fish and Wildlife Service under the Endangered Species Act.Read More
Water quality issues are shifting in the United States’ rivers in big ways.
Those changes are driven, in part, by the way the land in a watershed is used and they’re big enough that researchers may need to change the way they think about water quality in the American rivers.
“What was striking to us was how perceptions of water quality issues from several decades ago may need to be updated,” said Edward Stets, a U S Geological Survey research ecologist, in an email response to questions from Environmental Monitor.
New research by Stets published in Environmental Science &; Technology in March highlights these shifting water quality issues.Read More
