This blog, the first of two Healthy Waters blogs this week, focuses on adaptation to a changing climate.
In recent years, I’ve experienced a lot of wild weather here in the mid-Atlantic: torrential rains have caused flooded basements on my street; hurricane-force winds and derechos have downed our beautiful trees and caused power outages; and epic snowstorms have kept me from getting to work (and gave my kids way more snow days than we had planned for). We have also bemoaned both extreme heat and bitter cold.
A vast body of scientific assessment tells us that as the climate continues to change, we can expect to see trends toward more of this extreme weather and that there are a range of impacts that we should plan for. To protect our water supplies, we need to consider everything from the impact of increases in temperature on water quality and aquatic life to careful groundwater management to changes in how much water is used and what it is used for. And as we plan, we can no longer rely on past conditions as a predictor for what will happen in coming decades.
These weather phenomena can also have other consequences that not everyone thinks about right away, like interruptions in drinking water supplies and overwhelmed wastewater treatment plants. To help minimize these impacts, EPA has been working with states and water and wastewater utilities across the mid-Atlantic to translate the volumes of climate change assessments into practical actions they can take to make sure they’re prepared for weather-related emergencies as well as the impacts of climate change on water resources. States across the country have set up networks of utilities that have volunteered to help each other when disasters arise. EPA also partners with states to provide information to help water utilities and individuals ensure a safe supply of water when weather-related emergencies are threatening. EPA has also engaged with audiences across the region – from college students in Virginia to mayors in Delaware – to discuss the expected effects a changing climate has on our water resources and on our communities.
Although we have made tremendous progress in protecting and restoring our water resources, climate data shows the urgency of staying vigilant in our preparedness for severe weather events even as we are taking steps to adapt to the longer-term changes already underway. Our children and grandchildren are depending on us to make decisions today that ensure safe, reliable water resources now and into the future.
