| Stormwater carries pollutants that end up in our waterways. |
Why do we need rain gardens?
Sequestering stormwater reduces pollution of our waterways and of our aquifers. This is because stormwater runoff carries: fertilizers, sediments, plant matter, manures, pesticides, herbicides, salts, oils and other vehicular drippage.
Pollution that originates from numerous, diffuse sources, such as our yards is called Non-Point-Source (NPS) and the Environmental Protection Agency (EPA) estimates that NPS pollution is the largest threat to our waterways. But, we can reduce NPS pollution from our yards and from our communities by holding or sequestering more rainwater by installing rain barrels and by building rain gardens.
