Technical Documents

FOUNDATIONAL DOCUMENTS

The Assessment Reports and  the Source Protection Plan for the CTC Source Protection Region were created through a local, science-based process. Water quality and quantity studies were completed for each municipal well to assess vulnerability and identify threats. Drinking water threats were also modeled for surface water intakes on Lake Ontario. The technical studies that informed the Assessment Report are provided below.
