Today’s Topics:
• Why stormwater matters
– Impacts of stormwater runoff
– Exercise: Map stormwater flow through the DPW facility.
Session 1 Objectives:
Understand how stormwater pollution is affecting our local streams and ponds.
Recognize how stormwater flows through our facility and where it ends up.

…And the major source of pollution to RI waters
Stormwater pollution is now the #1 water quality problem in the U.S.

In R.I. 22% of surface waters are not meeting fishable swimmable standards due to stormwater pollution. - RIDEM
In recent years, up to 75% of annual beach closures were traced to stormwater, with the remainder due to CSOs - RI Health

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.

Why focus on public works facilities?
Water Quality Materials used or stored can pollute stormwater
Water Quantity High pavement, high runoff
Sediment Nutrients Bacteria Oil, toxics Trash Road salt Thermal Stress

Polluted Stormwater: Water Quality Impacts
Organic matter impairs taste & odor
Toxics– makes fish unsafe to eat
Nutrients lead to low dissolved oxygen and fish kills.
Algae and aquatic plants limit recreational use.

SummaryWe’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.

Exercise!
Inspect map(s) of facility site and surrounding area.
Draw water flow patterns on site map. What downstream resources could be affected?
How does stormwater flow through our facility?
