Runoff from rain or even your garden hose will collect such pollutants as chemicals, bacteria, oils and dirt. This runoff will flow through parking lots and streets untreated, picking up dangerous hydrocarbons as it travels. Eventually, this water will find its' way to lakes, rivers and other bodies of water, which provide us with swimming, fishing and drinking. Stormwater filters help prevent the runoff from rain and other water that can pollute our water supply.
Stormwater filters are designed to capture these contaminants as they make their way into storm drains. Stormwater filters come in an array of sizes and styles and have many applications. One way to locate businesses that manufacture, sell or install storm water filters is an online search. Simply enter, "Stormwater Filters." If you lack the technical comfort of deciphering a product befitting your needs, consult a landscaping or engineering firm.
The Environmental Protection Agency has weighed in on this subject for years. The EPA believes that urban runoff is "the biggest remaining contributor to water pollution." One EPA study measures the use of sand as a form of media for stormwater filters. Sand, peat-sand, activated carbon-sand, zeolite sand and enretech sand were reviewed and rated good, moderate and excellent.
With ever-increasing uses of pesticides on golf courses, residential lawns, business park grounds and sports facilities, stormwater filters should be in demand for quite some time. Many of these pesticides contribute to runoff hydrocarbons.
Stormwater filters also present water contamination by fossil fuels and other industrial contaminants.
Fearing further contamination as well as litigation regarding the health hazards of runoff, many urban areas are proposing the use of stormwater filters to prevent further pollution. San Francisco, California and South Tampa Florida are two examples.
Stormwater filters and other pollution preventatives are solutions to an issue that will not be disappearing anytime soon.
