As part of this program the Texas Regional Integrated Atmospheric Deposition Study (TRIADS) was established with a sampling site located in Seabrook, Texas in order to monitor atmospheric deposition of contaminants to Galveston Bay. Organic rain samples were collected with a Baker wet deposition sampler that collects the rain falling into a 1 m^2 surface area. The rain was then gravity filtered through a glass wool plug and a glass fiber filter that remove particles and then a column containing XAD-2 resin that collects the dissolved organic contaminants. The contaminants on the XAD-2 resin are operationally defined as dissolved, while the contaminants on the filter are operationally defined as particulate.polychlorinated biphenyls (PCBs)Chapter
