R. Scott Teed, B.Sc., GIS Certificate,EP
Mr. Teed has 17 years of experience in ecological risk assessment (ERA) including exposure and effects assessments for aquatic and wildlife species exposed to commercial chemicals, pesticides and other environmental contaminants. Mr. Teed has been involved in conducting ecological risk assessments for several contaminated sites in Canada and the US. For example, he is currently the lead ecological risk assessor for a former oil refinery site in Alberta and for a former railway site in Thunder Bay, Ontario. In the US, Mr. Teed participated in ecological risk assessments for the Housatonic River, MA and the Calcasieu Estuary, LA CERCLA (Superfund) contaminated sites. Mr. Teed has either, managed or participated in refined ecological risk assessments of numerous pesticides including glufosinate, carbofuran, simazine, aldicarb, chlorpyrifos, imidacloprid, permethrin, methomyl, tefluthrin, fluoxypyr, pendimethalin, trichlorfon, malathion, dimethoate, and others. Most assessments involved probabilistic exposure and effects methods to determine the magnitude of risk to ecological receptors. These assessments included endangered species assessments for the California Red-Legged Frog (CRLF), re-registration assessments under the FIFRA and/or the PCPA, support for registration of additional use patterns, standards development, and derivation of risk mitigation options. He has also led the assessment of potential risk from pesticide mixtures in the California Central valley.
Mr. Teed provides geographic information system (GIS), database, and application development support to Intrinsik clients. He is one of the main developers of the Granular Pesticide Avian Risk Assessment (GranPARAM) and Liquid Pesticide Avian Risk Assessment model (LiquidPARAM). Mr. Teed previously worked in the (now) National Guidelines and Standards Office of Environment Canada for 5 years where he developed soil quality guidelines under the National Contaminated Sites Action Plan (NCSRP) (now FCSAP), CCME water quality and tissue residue guidelines and evaluated commercial chemicals (tetrachloroethylene) that were included on the Priority Substances List (PSL). Mr. Teed is familiar with Canada’s Chemicals Management Plan (CMP) having reviewed several screening-level risk assessments produced under the CMP.
