Responding to Water Impacts of Climate Change
By Christina Catanese
When we hear predictions such as temperature increases of 3 degrees Celsius, and 13 inches of sea level rise resulting from climate change, we wonder what that means for us and our communities. If the ocean is at your front door, the threat is pretty clear. But for the rest of us, the implications are not so apparent. For example, did you know that climate change could impact the systems that bring us our drinking water and prevent flooding and sewer overflows?
While the impacts will vary significantly from one region to another, climate change is almost certain to cause more extreme weather events, including changing precipitation patterns and increased severity of drought and flooding. Greater frequency and intensity of rain events could also overwhelm our systems that are designed to deal with them.
As temperatures increase and sea levels rise, salt water is likely to intrude in to surface and groundwater, resulting in more water impairment. This can make the already challenging job for our drinking water treatment operators even tougher, and cause treatment costs to rise, which would impact our pocketbooks.

How should EPA’s water programs respond to climate change? In response to these challenges, EPA recently drafted the 2012 Strategy Response to Climate Change to address impacts to water and how they could affect EPA’s water programs. And we’re looking for your input.
You have until May 17th to provide your comments on this draft strategy. Find out how to comment here!
Making sure that EPA’s programs continue to protect human health and the environment even in changing climate conditions will require collaboration from all of us. We hope you’ll join us in facing up to this challenge!
