  "term": "Stormwater",
  "field": "Environment",
  "definition": "1. Refers to rainwater as well as water from washing cars, overwatering lawns, and other sources. Stromwater washes down storm drains on the curbs of roads and leads directly into lakes, rivers, and streams untreated. Stormwater can carry pollution directly into our natural water resources.\n\n2. Stormwater runoff, snow melt runoff, and surface runoff and drainage.\n\n3. Any precipitation in an urban or suburban area that does not evaporate or soak into the ground, but instead collects and flows into storm drains, rivers and streams. Stormwater is also called urban stormwater, stormwater runoff and polluted runoff. Increased development across the Chesapeake Bay watershed has made stormwater the fastest growing source of pollution to the Bay and its rivers and streams.\n\n4. Stormwater is water from precipitation and snowmelt events. Stormwater runoff is generated when precipitation flows over land or impervious surfaces and does not percolate into the ground. In the process of flowing over the land or impervious surfaces, stormwater can accumulate debris, chemicals, sediment or other pollutants that can adversely affect water quality if the runoff is discharged into streams or lakes untreated.\n\n5. Stormwater runoff, snow melt runoff, and surface runoff and drainage; rainfall that does not infiltrate the ground or evaporate because of impervious land surfaces but instead flows onto adjacent land or watercourses or is routed into drain/sewer systems.\n\n6. Precipitation in an urban or suburban area that does not evaporate or soak into the ground, but instead collects and flows into storm drains, rivers and streams. Stormwater is also called urban stormwater, stormwater runoff and polluted runoff. Increased development across the Chesapeake Bay watershed has made stormwater the fastest growing source of pollution to the Bay and its rivers and streams.\n\n7. rain or snowmelt that runs-off the landscape and which may carry pollutants to waterbodies.\n\n8. Stormwater is rain or snowmelt that runs-off of industrial and construction sites, streets, roads, parking lots, and other impervious surfaces, and which carries pollutants from these areas into waterbodies.",
