Denis Crean swims in the Potomac River two times a week. He takes others in, too, to teach them techniques for traversing the open water.
The most common response when he tells people, he said, is shock: “You go swimming where?!”
But those who monitor and patrol the river said getting people back into the water has always been the goal. To that end, the Potomac Riverkeeper Network announced Tuesday it will monitor water quality from six points along the river using a floating lab built into a 42-foot boat called the Sea Dog.
The data will be publicly released and uploaded to an app that allows people to check the quality of waterways and decide whether the water is safe enough for a swim.
