Drones Are the New Cost-Effective Way to Monitor the Environment

Riverkeepers, researchers and volunteer monitors have long kept an eye on water quality from the ground and from the river. But, with the help of technology that’s suddenly far more accessible, they’re taking to the skies, too.

Unmanned aerial vehicles, also called UAVs or drones, have recently become so affordable and easy to fly that they are winding up in the hands of more environmentalists.

Pipeline opponents and watchdog groups are a perfect example.

“The technology has come along to the point where everyday people can put a camera up in the air and see beyond the tree line or their property line,” said Ben Cunningham, Virginia field coordinator for the Pipeline Compliance Surveillance Initiative, a program that is training volunteers to use drones to keep tabs on controversial natural gas pipeline construction projects.

With the help of this equipment, he said, they’ve created an oversight system that is often “superior to what regulators have at their disposal.”

The Federal Aviation Administration predicts that about 7 million hobby and commercial drones will be sold in 2020 — nearly three times the 2.5 million sold in 2016.

The fast-growing fleet of drones includes small, sophisticated airplanes and quadcopters that, in some cases, are as easy to pilot as a remote-controlled car. Outfitted with auto-piloting functions and the ability to record images through a smartphone screen, some basic models start at less than $200, with advanced versions beginning around $1,000.

Tracking pipelines

In the Chesapeake Bay watershed, volunteers are getting licenses for drones in order to track the construction of natural gas pipelines.

Researchers are using them to measure the growth of Bay grasses and detect the presence of harmful algal blooms in the summer.

Riverkeepers are using the flyers to keep an eye on industrial facilities and take stunning footage of the waterways they’re working to protect.

Many of the Chesapeake region’s riverkeepers regularly use drones to help identify sources of pollutants, collect evidence for legal cases and regulatory complaints, or create promotional videos about their work.

“We could potentially get all of the riverkeepers together and have not only a Navy but an Air Force at this point,” said James Riverkeeper Jamie Brunkow.

Choptank Riverkeeper Matt Pluta agreed. He said it’s become known around the Chester and Sassafras rivers he oversees that the riverkeepers have a drone, “so it’s been pretty effective so far.”

Pluta has used the drone to track the expansion of Bay grass beds to ensure they are being protected. He also used it to showcase a two-stage ditch his organization helped construct on the edge of an agricultural field in Talbot County to reduce pollution in nearby waterways.

In the footage shared on social media, the drone provides a bird’s-eye view of the altered ditch designed to slow and filter nutrient-rich runoff before it reaches the river.

“The drone has allowed us to capture these projects in a way that we were not able to in the past,” Pluta said.

A drone expert in the Upper Potomac

Upper Potomac Riverkeeper Brent Walls has become the resident drone expert among some riverkeepers, many of whom have purchased the equipment in the last year or two. Walls has been flying drones for at least three years and navigating remote-controlled gadgets since childhood.

Walls recently upgraded his personal drone to the DJI Mavic Pro, which starts at about $800, and he uses it frequently for work. He even found floating footwear for the drone that allows it to land on the water — a product he’s shared with other riverkeepers.

On a January day, Walls mounted a 360-degree camera beneath his camera-equipped flyer to create a ride-along experience for Facebook followers while he navigated the drone over a snow-lined Antietam Creek.

“Being able to see something from the air gives you a whole new perspective,” Walls said. “The whole point of social media is to keep people engaged so when you need them to act — to write a letter or show up at an event in force — they’re there. This is one tool I use all the time.”

In the past, Walls would have to hire commercial pilots to gather aerial imagery or to keep an eye on an industrial facility he suspected was polluting a nearby waterway.

Now, he can get a drone up in the air and over the facility within a few hours. Sophisticated drone software makes it easy to edit videos on a smartphone and post them online as soon as they’re made.

Walls used the drone this summer to help Shenandoah Riverkeeper Mark Frondorf track the source of pollution that caused a sudden algae bloom in the river. Recently, the drone has helped Walls track oil seeps from a power plant and keep tabs on a mining facility’s stormwater pond, which he suspects wasn’t properly constructed.

But flying the expensive equipment, especially near privately owned facilities, isn’t for the faint of heart — or the untrained.
