Fields Point Water Pollution in RI?Public perception and progress Industrial & municipal discharges CSO improvements
Stormwater pollution is now the #1 water quality problem in the U.S. …And the major source of pollution to RI waters
In recent years, up to 75% of annual beach closures were traced to stormwater, with the remainder due to CSOs - RI Health In R.I. 22% of surface waters are not meeting fishable swimmable standards due to stormwater pollution. - RIDEM
What is Stormwater pollution? • Rainwater falling on roads, parking lots and other impervious surfaces picks up oil, spills, road sand and salt, sediment from construction sites, fertilizers, animal waste and discharges it to the nearest stormdrain without treatment. http://www.oceanservice.noaa.gov/education/kits/estuaries/media/supp_estuar09c_pathogens.html
30% runoff 15% 55% Development Impacts on Water Flow 40% 10% runoff 50%
Erosion Increased runoff quantity Flooding Development Impacts on Water Quantity
Development Impacts on Water Quality • Sediment • Nutrients • Bacteria & viruses • Oil, toxics • Debris • Road salt • Thermal Stress More Runoff = More Pollutants
Sediment • Nutrients • Bacteria • Oil, toxics • Trash • Road salt • Thermal Stress Water Quantity High pavement, high runoff Why focus on public works facilities? Water Quality Materials used or stored can pollute stormwater
Toxics– makes fish unsafe to eat Algae and aquatic plants limit recreational use. Organic matter impairs taste & odor Nutrients lead to low dissolved oxygen and fish kills. Polluted Stormwater: Water Quality Impacts
We’ve made a lot of progress in controlling water pollution to our rivers, lakes and bay. Now managing stormwater pollution is the next step to keep our waters clean and healthy. Stormwater pollution comes from many small sources with no single solution. But it takes just a few simple steps to get started. Summary
