Aeroqual won the air monitoring technology challenge conducted by Arcadis US Inc., the Supervising Contractor on the Curtis Specialty Paper Superfund Site in Milford, New Jersey. The 86-acre former paper mill site was contaminated with polychlorinated biphenyls (PCBs) in the soil and volatile organic compounds (VOCs) in the groundwater. In 2009, the EPA included the site in the National Priorities List of the Superfund program.

The cleanup activities involved removing storage tanks, disposing of hazardous chemicals, demolishing four large smokestacks and over 70 buildings, and extracting 10,500 yards of contaminated soil. Since PCBs can harm the immune, reproductive, nervous, and endocrine systems and are potentially carcinogenic, monitoring and controlling fugitive dust and vapor emissions played a vital role in the cleanup process.

Arcadis conducted extensive air quality measurements and compared perimeter air monitoring systems from three providers. The challenge evaluated data accuracy, system reliability, ease of deployment, and productivity tools offered by the software. Aeroqual AQS 1 air monitors were deployed in the trial to measure particulates (PM₁₀ and PM_2.5) and VOCs in real-time. Aeroqual Cloud captured air quality data and provided alert functions, which Arcadis project managers could use to generate reports and journal exceedances and make informed decisions about implementing emission controls and suppression.

The robust approach to air monitoring, dust control, and suppression measures enabled Arcadis to comply with NJDEP regulations and protect workers and public health during remedial activities. The Aeroqual system exceeded expectations for reducing risk and cost of compliance and was declared the challenge winner. Arcadis has confidently switched to using Aeroqual solutions for other Superfund site projects and Brownfield Cleanup Programs.
