The black cases are their latest innovation in stormwater science. Robotic samplers anchor in key sections of the watershed to monitor not only flow, but also the chemicals and pollutants washing downstream toward the Bay.<\/p>\n
“And this is a front-line pollution sampler. It’s getting the stormwater before it enters the Bay. And so, we want to know what’s coming into the Bay and getting these samplers out there in more locations will give us a better idea of where we might have issues, where a hotspot is, or maybe a previously unknown contaminant,” says Paterson.<\/p>\n
“It’s important to get out that fast,” her colleague David Peterson adds. “You know, in these storms as they’re happening, because the water is picking up pollutants in real time, and we need to be there to capture them.”<\/p>\n
When we first met Peterson several years ago, he and another Estuary Institute team were sampling water along the Bay shoreline by hand, a technique that’s still valuable. But to cover more ground, Kayli and a group of collaborators began developing the robotic samplers over recent storm seasons.<\/p>\n
Kayli and David start by chaining the unit itself to a tree near the creek bank. The system employs remote-controlled pumps that draw samples from the creek and store them in onboard containers. The software controlling the volume and frequency can be operated from a phone app.<\/p>\n
