The latest cleanup of lead-contaminated soil from the Mill River is very visible these days, as dredging equipment has been moved into the water just above the Tide Mill dam.

Exide is under orders from the state Department of Energy and Environmental Protection to remove the soil from the riverbed, contaminated by discharges from the company's former battery factory on the Post Road. The land where the factory stood has been remediated and is now the site where the soils dredged up are de-watered.

Once de-watered, the water is filtered and returned to the Mill River; the contaminated soils will be trucked off-site.

According to Conservation Department staff, Exide asked, and received, permission to do area 3 above the dam because the time of the year when work can be conducted there is limited because of shellfishing and migratory fish.

Remediation in area 5, located north of Interstate 95, is completed.
