White Paper   |   Dec 15th, 2018 “Nuisance Dusts” – Validation and Application of a Novel Dry Deposition Method for Total Dust Fall


The total dust fall monitoring program included measures for validation of the customized monitoring method as well as collection of data defining what constitutes background particulate levels in the study area. These background levels were needed as a “benchmark” in assigning significance to the program’s collected data in the absence of published regulatory values. The monitoring program was designed to measure total dust fall (non-respirable) as surface dust deposits and relied on passive particulate collection devices. Preconditioned and pre-weighed filter media were deployed at ten (10) sites in the metropolitan area. Residential hosts who agreed to participate in the program on a voluntary basis operated the majority of the sites used. Criteria for site selection included coverage of all wind vectors in the vicinity of coal handling processes at the power plant as well as residential properties where nuisance dust complaints had been recorded previously. Filter collection media were employed for sampling events expected to last one calendar week or seven (7) days. This provided an exposure period that maximized collection of particulate matter, and yet limited non-detected values. All residential hosts received training in filter deployment, recovery, handling and shipping procedures.
