Here in New England, climate change is already impacting the quality of drinking water supply reservoirs and impoundments. More erratic precipitation patterns, increasingly heavy precipitation events and changing stream flow patterns are here. How are these weather changes impacting water quality? How can we monitor our water supplies to plan ahead for changes that may be needed to our treatment facilities?
Tracking Changes and Trends
Identifying key water quality indicators and tracking changes and trends over time is the best predictive tool to understand if your source of supply is at risk from climate change. For example, tracking mercury concentrations in your reservoir water column is one such indicator.
