The KnowYourH2O Path to Clean Water Program was created to raise awareness of the threats to the health and safety of our drinking water supplies and sources which can impact your health, your families health, and your home and community.
We believe that, when we inform the community, we empower individuals, support fact-based citizen science, and give communities the resources and tools they need to be aware of the risk to their water supplies, to manage hazards and concerns, and to mitigate risk for current and future generations.
In addition to protecting our nation's drinking water sources, recreational waters, streams, lakes, rivers, and oceans, we are implementing a fact-based science approach that will help to assure that this most valuable resource, clean, safe, drinking water, is safe for generations to come; we need to be stewards for all of the inhabitants of this beautiful blue ball.
