Providing minute-by-minute data uploads to help protect air quality.

Since 1987, Wood has been tracking pollutants across the US and Canada with CASTNET, the US Environmental Protection Agency's (EPA's) Clean Air Status and Trends Network project. With more than 90 remote locations in partnership with federal, state and local agencies, we have played a key role in monitoring the reduction of sulphur, nitrogen and ozone concentrations in the atmosphere.

Each station consists of a 10 metre tower and a small trailer with monitoring equipment inside. Dozens of local partners, ranging from academic professors, graduate students, retired teachers and farmers, help maintain these stations for 24/7 data collection. Sites have internet service provided by cellular modems. Over the years, hourly data collection has given way to minute and sub-minute data. With programme responsibility for all monitoring equipment, information collection/tracking and analytical services, our critical product to the EPA is this consistent, high-quantity and -quality data.

The hallmarks of our programme are strong QA/QC, an ISO/IEC 17025-accredited analytical chemistry laboratory, a field operation department that performs regular maintenance and deploys new technologies, and a data management group that delivers quality information. The results from Contractor Performance Assessment Report ratings by EPA are “Exceptional” across all programme categories during the current and previous contract. EPA frequently cites specific programme achievements in their reviews, such as:

"In 2015, Wood successfully managed more than 90 remote monitoring stations, providing high-quality data while coming in $500,000 under budget for contract year:

  • Enhanced ozone monitoring at all CASTNET sites to meet additional regulatory requirements
  • Developed program that is now being used by states to assess ozone design values in rural areas
  • Provided very responsive service to both program technical office as well as contract office
  • Developed and implemented well-maintained tracking database for all property
  • Reduced overall costs of program so that program technical office could install additional monitoring capability"
