Abstract Long Description

Several Leaking Underground Storage Tanks (LUST) have created soil and groundwater contamination in the city of Montesano. Currently, there are 11 identified LUST sites in downtown Montesano, with the majority of these being located within a four block area. To determine the current extent of groundwater contamination, samples will be collected in fall 2004 and spring 2005 from approximately 35 existing monitoring wells for benzene, toluene, ethylbenzene and xylene, as well as total petroleum hydrocarbons as gasoline. Water level measurements from the wells will determine groundwater flow directions. This data will be helpful in determining which areas require additional investigation. This information also will be used when working with the local government to mitigate impacts that may be occurring as a result of contaminants from multiple sources creating an area-wide contaminant plume that′s potentially impacting utilities and surface water.
