A detailed hydrologic investigation was conducted at a wood preservative treatment plant to determine the extent of soil and groundwater contamination and to define the rate at which preservative compounds (polycyclic aromatic hydrocarbons and phenols) are migrating to an adjacent saltwater body. Contamination appears restricted to the uppermost aquifer, which occurs in a sequence of fill deposits comprising the land surface at the site. Groundwater flow and contaminant distribution are likely controlled by heterogeneities within the fill deposits, which are a result of placement history and other factors such as buried shorelines, bulkheads, and filled channels. Calculations of total contaminant flux from the groundwater system to the adjacent saltwater body range from 143 to 191 pounds per year. |
