Risk = excess cancer risk estimatecPAH = carcinogenic PAHsCOPC = chemical of potential concernD/F TEQ = dioxin and furan toxic equivalent (data available only at beaches 4, 5 and 7)
Excess cancer risk charts for individual beaches compare risks bychemical as a fraction of total risk from all COPCs. Chemicals other thanPCBs, arsenic, cPAHs, and dioxins and furans are not shown on chartsbecause they contribute 1% or less to the total risk. The size of each chartis proportional to the total risk, as defined by the scale in the legend.a Tax parcel information was provided in 2008 by Seattle Public Utilitiesand King County. Some tax parcel polygons were edited to conform tothe LDW shoreline presentation. A comprehensive survey of property-owner records was not conducted.b cPAH concentrations are based on benzo(a)pyrene equivalents. TEQswere calculated with mammalian PEFs for seven individual PAHcompounds (California EPA 1994), using one-half the RL for undetectedcompounds. Because of the potential for increased susceptibility ofchildren to carcinogens with mutagenic activity, as described in EPAguidance (EPA 2005), the risk estimate for beach play RME for cPAHsis based on dose adjustments across the 0-to-6-year age range ofchildren. See Section B.5.1 for more information.

a Clams were collected in 2007 but were not analyzed for cPAHs.b Areas used to estimate the sediment SWAC in clam tissue/sedimentregressions.c Percentiles were calculated on an area basis as the concentration atwhich a particular percentage of the LDW area has interpolated valuesless than or equal to that concentration (e.g., the 95th percentile is theconcentration at which 95% of the LDW area has interpolatedconcentrations ≤ 1,100 µg/kg dw). Interpolated concentrations werecalculated including locations with non-detected values. cPAHconcentrations are based on benzo(a)pyrene equivalents. TEQs werecalculated with mammalian PEFs for seven individual PAH compounds(California EPA 1994), using one-half the RL for undetected compounds.
