Drone technology has (forgive the pun) taken off in the last decade. These now-ubiquitous unmanned aerial vehicles (UAVs) are being used by industries across the spectrum from entertainment to archaeology.
Drones are vital tools within the full scope of Environmental Health and Safety (EHS) solutions as well. This is the first in a series of posts that will examine the work drones do to make EHS solutions more efficient, effective and safe. Watch for more as we share short videos on our LinkedIn page and YouTube.
Here we’ll explore how drones help EHS professionals safely undertake site investigation and remediation.
What Is Investigation and Remediation?The process of investigation and remediation involves site analysis, removal of pollutants and contamination from surface water, groundwater, and soil..
Investigation and remediation services include steps such as:
Soil, groundwater, and surface water investigations (Phase I and Phase II)
Development of Conceptual Site Models and remediation strategies
Human and Environmental Risk Assessments
Innovative Remedial Design
Implementation, optimization, and monitoring of on-site remediation systems
Waste disposal, including hazardous waste
Drone Technology That Powers EHSThe technology powering today’s most sophisticated drones is making them an invaluable part of EHS work.
LiDARLight Detection and Ranging (LiDAR) has fast become a tool with a thousand uses.
This technology is similar to sonar in how it works, measuring the time it takes for the laser light to bounce off a target. These measurements are compiled and used to create a precise 3D model of an object or area.
A significant benefit of LiDAR is its ability to collect data beyond a canopy of trees or other concealing vegetation. This is especially useful when trying to get an accurate assessment of ground formations or detect concealed objects.
Drone-mounted LiDAR is a more affordable, more accessible solution than gathering LiDAR data using planes, helicopters, or satellites.
Other specialized sensorsCertain sensors detect airborne particulate matter and analyze concentrations of pollutants. Thermal sensors capture temperature information. Hyperspectral sensors gather information from across the electromagnetic spectrum.
Each of these specialized sensors can be used in any number of applications, including EHS remediation.
Artificial intelligenceArtificial intelligence (AI) is the brain that powers today’s cutting-edge drones. AI allows drones to fly in complex situations, such as inside buildings, and stitch images together to form comprehensive 3D models. This process is made faster and more effective through technologies like AI.
AI also powers the drone’s recognition capabilities, enabling object inventory and change alerts for site monitoring.
Drones in RemediationDrones are being deployed to assist with remediation in a number of ways, reducing risk of exposure to hazardous situations.
Investigation and remediationSome ways drones are being put to use for investigation and remediation include:
Site mapping. Drones are being used to create accurate and detailed site maps, as well as to measure and map facilities.
Watershed mapping. Using LiDAR, thermal mapping, and other sensors, drones can map watersheds and determine routes water takes within the affected zone.
Aerosol distribution. Using those specialized sensors mentioned above, drones can sense concentrations of CO2, CO, NH3, SO2, PM, O3 and NO2.
Water pollution. Other specialized sensors can detect seepage from holding tanks, or determine if groundwater is infiltrating surface water near a polluted site.
Plant health. Image processing outputs compare different light bands in the RGB-captured image. This method uses Visible Atmospheric Resistant Index (VARI) to give visual indications of plant health and is intended for agricultural use.
Difficult inspections. Quick, inexpensive, remote access inspections for objects large enough to be identified in photos and videos. Drones are capable of accessing difficult areas or areas that introduce a hazard for human access.
Volume estimation. Produce estimates for soil management, volume capacities for catchment like features, volume of excavation materials.
Leak detection. Routine real-time aerial images and videos can capture images of leaks or unauthorized activities near critical infrastructure, often in remote areas not visible from the ground.
Remediation monitoring. Once remediation is underway, drones can monitor remediation efforts and measure zones subject to contaminant removal, among many other uses.
Pilots matterWhile technology has expanded what we are capable of learning in the field of EHS remediation, the human factor makes a difference in how data is gathered and extrapolated.
Pilots who are also engineers or technicians with experience in the field of EHS remediation or related work have years of experience knowing what to look for in situations where drones have replaced feet-on-the-ground (or, in some cases, seats in the air).
