The Ministry of the Environment needs to do more to clean up contamination along Canagagigue Creek, Woolwich Township councillors say.
Councillors voted Tuesday night to send a letter demanding more action from the ministry.
The creekbed runs through the Chemtura property in Elmira.
Tests conducted earlier this year showed high levels of DDT, a banned pesticide, in the creekbed.
Fifty metres downstream of the plant, DDT was found at 2,900 times the level considered safe.
A report prepared for the township warned of a potential “environmental crisis” if the contamination was not dealt with.
Chemtura representatives have said that the contamination was related to chemicals manufactured at the plant decades in the past, which they have been aware of since the 1990s.
DDT has only been found in the sediment along the creekbed of Canagagigue Creek, not in the water itself.
Township officials estimate that the province has already spent $36.5 million on hazardous waste cleanup in the creekbed.
