For the first time since moving to Concord some 22 years ago, I found the beach at Walden Pond vacant on a warm summer afternoon. It will remain closed until a new pavilion is constructed to replace the old one.

I spent a good part of the afternoon doing aerial photography around town as an excuse to be outside. I have been suffering from the flu for the past few days and needed to do something other than sleep.

Pictured below is the WR Grace Superfund Site located on the town line between Acton and Concord. Grace acquired the site in 1954, using it to make concrete additives, organic chemicals, container sealing compounds, latex products, and paper and plastic battery separators. Wastes from these operations were discharged into unlined lagoons or buried in landfills onsite, contaminating soil, sediment, and groundwater. The surface contaminants have been removed, and a 5 megawatt solar field has been installed. Groundwater remediation is ongoing and expected to continue through at least 2031.
