Description | Groundwater samples for BTEX, TPH-G, and VOCs were collected in September 2008 and April 2009 from 25 monitoring wells in downtown Montesano. Analytical data show the surficial aquifer is contaminated with petroleum products, primarily from three source areas: Whitney’s Inc./Key Bank (Sterling), Tony’s Short Stop/Grays Harbor Grange, and Brumfield-Twidwell. Petroleum contamination from Whitney’s Inc. and Tony’s Short Stop has possibly co-mingled to form a large plume across downtown Montesano. Low concentrations of chlorinated compounds have also been detected in some wells at Key Bank (Sterling) and Grays Harbor Grange, which may indicate the presence of VOC-contaminated plumes in these parts of the study area. |
