STORMWATER City of Lawton
� � � In the beginning… Humans unknowingly contaminated sources of drinking water with raw sewage, which led to diseases such as cholera and typhoid. Water pollution intensified with the advent of the Industrial Revolution, when factories began releasing pollutants directly into rivers and stream. In 1969, chemical waste released into Ohio’s Cuyahoga River caused it to burst into flames. Up to 500 million tons of heavy metals, solvents and toxic sludge slipped into the global water supply every year. Water sources contaminated by rain runoff from such things as oil-slick roads; construction, mining and dump sites; and livestock wastes from farm operations. Leaky septic tanks, pesticides and fertilizers contaminated groundwater.
Clean Water Act of 1972 The objective was to restore and maintain the chemical, physical and biological integrity of the nation’s waters by preventing point and nonpoint pollution sources.

What is STORMWATER… � � Stormwater is just what is sounds like: water from a storm. Any precipitation that falls from the sky, including rain, hail, and snow, is considered stormwater. In a natural landscape without development, stormwater is absorbed into the ground or falls into bodies of water. This gives needed water to plants and animals and replenishes reserves of surface and groundwater. In an urban landscape, stormwater falls onto impervious surfaces (surfaces that do not absorb water) such as roads, sidewalks, rooftops, or parking lots and is not soaked up by the ground. As a result, the falling water is swept across these surfaces as runoff. As the runoff flows across the ground, it picks up pollutants and carries them into local waterways, such as rivers, lakes, and streams, before eventually making its way into the ocean.

Stormwater Management’s Goal Reduce the existing potential for stormwater damage to public health, safety, life and property. Protect and enhance the quality, quantity and availability of surface and groundwater resources. Preserve and enhance existing aquatic and riparian environments and encourage restoration of degraded areas. Control sediment and erosion in and from drainage ways, developments and construction sites. From Street to Stream Keep it Clean
