| Short Description |
During April and August 2006, groundwater samples were collected from seven monitoring wells at the former Saginaw Mill site in Aberdeen to assess the progress of ongoing phytoremediation (poplar trees) to reduce formaldehyde concentrations at the site. Formaldehyde was detected in samples from the six on-site wells at concentrations ranging from an estimated 13 to 65 ug/L. Formaldehyde was also detected in samples from the one off-site well at estimated concentrations of 12 and 22 ug/L. Formaldehyde concentrations in the seven monitoring wells were below the MTCA Method B non-carcinogenic cleanup level of 1,200 ug/L. (Also see abstract below) | |||

| Abstract | Long Description |
During April and August 2006, groundwater samples to be analyzed for formaldehyde were collected from seven monitoring wells at the former Saginaw Mill site. The mill was located in Aberdeen, Washington, on the south shore of the Chehalis River where the river enters Grays Harbor. Samples were collected to assess the progress of ongoing phytoremediation (poplar trees) to reduce formaldehyde concentrations at the site.
A sample to be analyzed for total petroleum hydrocarbons as diesel (TPH-Dx) was collected from well MW-1 in April 2006. TPH-Dx was not detected in this sample at the reporting limit of 0.05 mg/L. Since formaldehyde concentrations in the groundwater are below the current MTCA Method B cleanup level and are near the analytical reporting limit, it is recommended that no further monitoring is needed at this site. Well MW-5 was damaged sometime between the April and August 2006 sampling. This well should be decommissioned. |
