An oil spill into the Sympaug Brook in Danbury is being cleaned up. The waterway flows into the Still River. The Connecticut Department of Energy and Environmental Protection is overseeing the clean-up. The pill resulted from a hose failure at a manufacturing facility owned by Stanley Engineered Fastening, located at 4 Shelter Rock Lane. About 1,800 gallons of waste oil containing metals was assumed lost, and while some was recovered from secondary containment, some released into the brook, resulting in a milky-white color. Stanley has taken responsibility for the clean-up and has engaged Moran Environmental Recovery and Fuss & O’Neill to assist. Though the impacted area is not believed to be an active area for recreation, the health department is recommending that fishing, bathing, or recreational activities do not occur in the affected areas until remediation is complete.
