2019
Drone Surveillance Leads to Protection of Pristine Trout Stream
In 2019, Brent Walls, Upper Potomac Riverkeeper, was part of a coalition to save beautiful Tom’s Creek in Adams County, PA, from devastation from sedimentary runoff from the Specialty Granules, Inc., (SGI) quarry. An historic and pristine trout stream was at real risk and so Brent and his team went into action.
Brent used his drone to photograph cloudy sediment discharging from the quarry’s settling ponds. Those images gave him the evidence he needed to file a Clean Water Act Notice of Intent to Sue against SGI. This is the first time, so far as we are aware, of drone photography being successfully used for this kind of enforcement activity.
And it worked! SGI has agreed to install a state of the art system to filter sediment and pollution out of its stormwater before it’s released to Tom’s Creek, a first for a quarry in our watershed.

The pollutants leaking into the river include “black liquor,” a caustic byproduct of the paper pulping process, as well as contaminants associated with coal ash waste.
