Stormwater runoff is the number one cause of stream impairment. Stormwater runoff, or rain flow that flows over ground surfaces, is created when rain falls on surfaces that do not allow water to soak into the ground. Examples are paved surfaces, such as roads, driveways, parking lots, and rooftops. When the water flows over the surfaces, it carries with it many different pollutants which are found on the surfaces. Pollutants like bacteria, grease, metals, nitrogen, oil, pesticides, phosphorus, sediment, and trash. These toxins come from a variety of places, like pet waste, lawn fertilization and pesticides, cars, construction, illegal dumping and spills.
Stormwater runoff pushes excess nutrients from pollutants into our waterways. These nutrients fuel the growth of algae which create low oxygen zones that suffocate marine life.
Stormwater runoff pushes excess sediment into our waterways which blocks sunlight from reaching the underwater gasses and suffocates shellfish.
Stormwater runoff pushes chemicals into our waterways which harms the health of wildlife and contaminates human water sources.
Stormwater runoff contributes to 30% of pollution if the Puget Sound. One-third of the polluted waters in the state of Washington is caused by stormwater runoff. It is the leading cause of beach closures, and contamination of drinking water.
Pollutants from stormwater runoff kills local fish and wildlife and eventually ends up in the Puget Sound. Flooding from stormwater runoff harms streams and wetlands, destroy8ing habitats needed for local fish and wildlife. During the rainy season, stormwater runoff rushes downstream and floods damage homes, business, and septic system drain fields.
45,000 shellfish growing beaches have closed since 1980, because of stormwater runoff. Even now, less than half of the salmon and steelhead stocks in the Sound are considered “healthy.”
The TS1 system is housed onsite in a self-contained unit, designed to catch stormwater runoff. The stormwater runoff moves through the unit combining with TS1 to turn heavy metals, such as copper, lead, and zinc in the runoff into safe, non-toxic waste for easy disposal.
