Installation of 52 groundwater monitoring wells at the Richmond Field Station begun in July 2010 is mostly complete. Environmental consultants are now beginning groundwater sampling for chemical analysis. In addition, around seventeen exising research water wells that are no longer needed will be closed through gouting beginning in late August. For more information on the scope of work, see the July 19, 2010 news item below.
At the neighboring former Zeneca property, site investigations will continue from August through October 2010 with the implementation of a new groundwater treatment pilot study in the central portion of the property (Lot 3) and continued groundwater sampling in the northwest (Lot 1) portion of the property. This work will include continued sampling to the south and southwest of RFS Building B478 (Forest Products Laboratory). See the August- October 2010 DTSC Work Notice for more information.
