Abstract Urban wet-weather sources of pollution such as Stormwater and combined sewer overflows (CSOs) can contribute significantly to the contamination of receiving waters, particularly in sediment depositional areas near outfalls. Analyses of sediment chemistry alone are not sufficient to fully assess the effects of these discharges. Toxicity testing and evaluations of benthic invertebrate communities, in conjunction with chemical analyses, provide a more complete characterization. This study assessed relationships among three separate aspects of the benthic environment:sediment chemistry (metals, PAHs and nutrients) and particle size, sediment toxicity (ten endpoints with four benthic taxa), and benthic invertebrate community structure. In this initial survey, ten sites in five different study areas, representing a range of receiving water environments exposed to Stormwater and CSO discharges, were sampled in October 1998. Results of analyses indicated that while contaminant (metals and PAHs) concentrations were relatively high in sediments, biological effects were not evident Toxicity of sediments was low and altered benthic communities were not detected. Neither toxicity endpoints nor benthic community descriptors were related to sediment contaminant levels. To improve the power of these assessments, future investigations of Stormwater and CSO discharge impacts should use “upstream/downstream” sampling designs and study sites with minimal variability of habitat conditions.

ABSTRACT The beach of Ediz Hook, Port Angeles, Washington, was heavily oiled by Alaska North Slope (ANS) crude oil spilled subsequent to the grounding of the Arco Anchorage on December 21, 1985. Intertidal crude oil concentrations measured in beach sediments ranged from less than 50 to 20,000 ppm, with an average of 2,240 ppm. Beach reclamation efforts, concluded in April 1986, reduced average crude oil concentrations to 670 ppm. An intertidal and subtidal sediment chemistry and benthic invertebrate monitoring program was initiated at Ediz Hook in 1986 and was concluded in early 1988. Sediment chemistry data indicated a decline in mean intertidal concentrations from 670 to 110 ppm between April 1986 and July 1987. Shallow subtidal concentrations decreased from a mean of 460 to 110 ppm in the same time period. Benthic invertebrate population indices, developed with core and box sampler data, generally demonstrated a negative correlation with sediment crude oil concentrations. Organism density, taxonomic diversity and biomass increased significantly at numerous stations during the course of the monitoring studies. Successful bivalve population recruitment and growth were evident for several hardshell clam species by the fall of 1987. There was no evidence of petroleum-derived hydrocarbons in the edible tissues of salmonids (rainbow trout and Atlantic salmon) which were gathered for several months after the spill from a net-pen culturing facility in Port Angeles. Despite vigorous bird rehabilitation efforts, approximately 80 percent of the 1,917 oiled birds perished. Pre- and post-spill population census data indicate, however, that population level impacts did not occur. Various reconnaissance, monitoring and damage assessment investigations conducted during and after the spill have documented the environmental value of a rapid and effective spill response and cleanup effort. Significant impacts associated with the spill were short-term in nature and generally limited to the immediate spill area.

Benthic Invertebrate Communities

Benthic invertebrate communities were investigated as part of the federal Environmental Effects Monitoring programs conducted as required by the amended Pulp and Paper Effluent Regulations (PPER) of the federal Fisheries Act. A Refiner Mechanical (RMP) and larger Kraft pulpmill, both situated on a northern, BC reservoir, discharge secondary-treated effluent within 5 km of each other. Efforts to independently distinguish potential effects associated with these individual discharges were complicated by the proximity of the diffusers, their location within a complex ecological region of a reservoir, and the presence of temporal and spatial confounding influences. A comprehensive examination of the benthic community structure involved the combined assessment of several endpoints (total population numbers, relative proportion of taxonomic groups, and species richness). A tiered, spatial approach, based on a reservoir ecological model (Thornton et al., 1981), was adapted to assess and distinguish community structures and reservoir- and mill-related influences. Results suggested that effects associated with the two different mills could be distinguished based on subtle and distinct differences in benthic community profiles.
