What is Stormwater Pollution?
Stormwater pollution can be many different things, including (but not limited to): trash & debris, nutrients, sediment, metals, oxygen demanding substances, oils & grease, and bacteria/pathogens. These pollutants have many sources and varying negative effects on the environment.
Where Does the Pollution Come from?
When it rains the runoff picks up the pollutants that have accumulated on the roads, driveways, rooftops, and other surfaces and carries them to the nearest storm drains. Most storm drains directly or indirectly connect to a river, lake, stream or ocean. The negative impacts of stormwater pollution are huge.
What are the Effects of Stormwater Pollution?
The effects of stormwater pollution are numerous and widespread. Beach closures, contaminated water, algae blooms, fish kills, bad odors, and the Great Pacific Garbage Patch are just a few of the impacts caused by stormwater pollution. The long term consequences of this continued pollution are still not completely understood.
What’s Being Done to Help?
Over the past 11 years, stormwater regulations have become increasingly stringent. All new construction is required to implement stormwater best management practices (BMPs) to reduce the number of pollutants discharged. One example of these BMPs are catch basin filters that are fitted into storm drains to collect pollutants as the runoff passes by. The MWS Linear, Water Polisher and The Kraken filters are all examples of very advanced filtration systems that have the ability to remove nutrients, trash, sediments, metals, and bacteria at high levels.
With everyone’s help, more education and better technology, it is possible to improve the current conditions for the future of the planet and all its creatures.
