This week I wanted to dig a little deeper into the equipment used by Arlington County’s volunteer stream monitoring effort. According to their website, they use a product called the Coliscan Easygel. I wanted to learn more about how this product works, how much it costs, and to identify some alternatives.
It turns out, the internet is full of easy, at-home tests for E. coli. Many are marketed to homeowners to provide a convenient DIY water testing kit. I did not discover why Arlington chose to use this one in particular, other than it is recommended by the State’s Department of Environmental Quality. However, it seems affordable and pretty simple to use. Check out the powerpoint below for more information!
