Some Newtown residents alerted officials about a milky substance in the Pootatuck River last week. The Newtown Bee reports the small bloom was determined to be nontoxic and not harmful to the trout stream. The milky substance was spotted near Commerce Road last Tuesday. Deputy Director of Planning Rob Sibley told the Bee that the small plume came up after nontoxic substances were forced out of a blocked curtain drain at St Rose of Lima Church during a storm water system replacement project. The pumped out and discolored water ran into the river.
