  • Full Profile

    Samuel Parker is an ecologist with over seven years of experience working on a variety of sediment and surface water issues. His work focuses on ecological risk assessment of contaminated sites regulated under CERCLA, RCRA, and state voluntary programs. In addition, Sam has a wealth of experience designing and implementing large-scale hydrologic and surface water quality monitoring programs that target surface water nutrients as well as other contaminants. Using multivariate and geostatistical analysis methods Sam strives to incorporate a mechanistic understanding of ecosystem process into effective risk-based decision making. He has developed novel approaches using remote sensing, high-resolution GPS, and geographic information systems to improve assessment techniques of sediments for use in the development of natural resource damage assessments (NRDA) and other baseline ecological risk assessment (BERA) programs.

    KEY EXPERIENCE

    Former Textile Manufacturing Facility, Virginia
    Technical Lead

    Project included the development and implementation of an assessment approach to map the spatial distribution of fine-grained sediment deposits throughout an 11-mile river reach. Locations of fine-grained sediment deposits across the 114-acre study area were used to identify areas of potential mercury contamination for a natural resource damages assessment (NRDA). Off-site substrate mapping investigation included extensive field-based mapping using high-resolution GPS units in conjunction with remote sensing technologies

    North Slope, Alaska
    Technical Lead

    Project included the design and implementation of comprehensive three year hydrologic, sediment, and surface water monitoring effort on a 30 mile2 watershed located in northern Alaska. This goal of this effort was to determine the background nutrient concentrations and loading observed in arctic streams with and without lakes present. This research was carried out to support the National Science Foundation SCALER Project (NSF#1065682). Site work included installation and maintenance of 11 continuously operated discharge gages, sediment evaluations, and nine watershed-scale synoptic surface water sampling efforts.

    Franklin County, Vermont
    Technical Support

    Project included the development of a landscape assessment model for the Vermont Farm Service Agency (USDA) to determine the benefits of returning fallow land back into productive farm land. This risk-based decision model considered natural resource impacts to wetlands and other receptors while accounting for soil fertility and potential crop yields.

    Former Explosives Manufacturing Facility, New Jersey
    Technical Support

    Project included the implementation of substrate mapping approach to inventory fine-grained sediment deposits throughout a 2.5-mile river reach. Spatial distribution of fine-grained deposits were used to develop comprehensive sampling approach as part of a BERA to identify risks associated with mercury contamination in benthic sediments and pore water.
