Accurate monitoring for effective compliance and detailed modeling
RWDI’s scientists and engineers help clients in diverse sectors and industries gain insight into the air quality impacts of their operations. In addition to exceptionally high-quality testing and monitoring, we provide thoughtful regulatory guidance and clear, easy to understand reports – including expert interpretations and recommendations informed by expertise across RWDI.
We work closely with operators to help them understand how complex air quality regulations apply to their projects and facilities. After gaining a thorough understanding of a client’s challenges and priorities, we help to craft a monitoring strategy that’s accurate, efficient and well suited to their scientific and operational context. We bring the same rigor and meticulous care to programs at any scale, whether it’s a one-off measurement project or long-term, multi-site monitoring program.
Monitoring for diverse applications.
In addition to compliance reporting, our monitoring work supports emissions modeling, toxicology and environmental impact assessments.
Field sampling, stations and networks.
We design, build, install, operate and maintain all types of ambient air quality monitoring programs. We provide both the instrumentation and the staff to get the job done.
Advanced solutions that are simple to use.
Our teams have deep expertise in a range of areas connected to air quality monitoring, including regulatory frameworks, meteorological influences, testing methodologies, operations and software development. This breadth of capabilities lets us deliver powerful solutions such as real-time monitoring tools with automated warning or response systems; long-term, continuous monitoring at large or challenging sites; and customized monitoring tools for unique conditions or pollutants.
Monitoring informed by meteorological insights.
We can complement air quality monitoring with valuable meteorological insights, designing monitoring programs to include continuous measurement of conditions like wind speed, wind direction, relative humidity, ambient temperature and solar radiation.
Expert witness testimony.
Our team supports clients by quantifying the consequences of accidental releases, and offering clear, data-driven assessments of the cumulative effects of emissions.
RWDI’s broad technical resources and extensive knowledge of testing methodologies mean we excel at designing advanced solutions for large or challenging projects.
Cost savings at a resource facility.
A client’s sampling site had been damaged, and rebuilding the same asset at the same location would cost $350,000. Instead of replicating the previous sampling set-up, we used our understanding of the fundamentals of the methodology to develop alternative configuration – and satisfied regulators that a sampling site at a new location would provide acceptable data. The move maintained our client’s regulatory compliance, cost almost nothing, and created a safer, more convenient work environment for their team.
Occupant comfort at hospitals.
Many hospitals need to test diesel generators monthly. To help operators run tests at times when they’re least likely to create nuisance odors, we’ve installed wind-direction sensors connected to warning signals. On the day of a scheduled generator test, if wind conditions are likely to disperse diesel exhaust toward occupants, the device alerts the user, who can reschedule the test to prevent discomfort and complaints.
Reduced staffing needs at a large construction site.
At a large construction site, we helped a client diminish their need for continuous human monitoring of particulate matter emissions. We developed an automated system that activates a camera and sends an email to site supervisors when particulate matter at a given monitor reaches a specific threshold. Numeric data and images are available on the web in real-time to both supervisors and regulators. When an alert is triggered, our client can immediately determine the cause (e.g., a passing truck vs. wind-blown dust) and adjust operations appropriately.
