Following are the five water systems in use in Woolwich Township (Elmira & St. Jacobs supplied by pipeline from Waterloo). All five of them, similar to the testing done for Cambridge, Kitchener and Waterloo, are not tested for common solvents and contaminants such as NDMA, Dioxins, Toluene, Xylene, Ethyl Benzene, 1,1,1 TCA. I would suggest that this is less problematic in the Townships than in the urban areas as these chemicals are directly related to industrial sources.

The West Montrose system has issues with both Chloramines and Trihalomethanes. These are by-products of disinfection. These are not minor issues and need to be significantly improved.

The Maryhill Village Heights system has issues with Nitrates. This most likely is due to their rural nature and the result of nearby farming practices. While below the Ontario Drinking Water Standards (ODWS), nevertheless this system has the highest Nitrates in the Woolwich Township wells.

The Maryhill Water Supply System consisting of two different wells than the former one just mentioned has Chloramines, similar to West Montrose, above the O.D.W.S. This needs to be addressed.

Both water systems in Conestogo have issues with Nitrates. Neither are above the O.D.W.S. although the Golf Course system is the higher of the two. As the Golf Course system consists of "river" wells, greater influence potentially from Uniroyal/Chemtura upstream would not surprise me. NDMA and Dioxins especially should be tested for in these wells.
