Stormwater describes rainfall, snowmelt, and other weather-related water which collects and runs off of hard surfaces like rooftops, parking lots and even sod. Stormwater is one of the most significant threats to water quality across the nation, simply because it's easily polluted with litter, debris, sediment and many different types of synthetic chemicals as it runs over hard surfaces.
Polluted stormwater collects into the storm drain systems of our local communities, where underground pipes carry this runoff to our local waterways. Our local stormwater is not currently treated through filtration or other mechanisms so any harmful substances and materials it picks up along its journey end up in our water, oftentimes in high-use areas like the Sand Creek corridor.
LPOW proactively addresses stormwater issues related to growth by monitoring shoreline development projects and reviewing NPDES Construction General Permits. LPOW also works to raise community awareness about how stormwater can impact water quality through the “Dump No Waste – Drains to Lake” Storm Drain Labeling Program.
LPOW is working hard to spearhead an exciting new Storm Water Monitoring Program (SWMP). Like our long-term Water Quality Monitoring Program, the SWMP will be driven by citizen science and community funding. To learn more and get involved, visit our SWMP page.
What's in Our Stormwater?
Our efforts to track stormwater pollution through monitoring are supported by generous community funding and citizen science. Get involved today to help LPOW protect our local waterways!
