Stormwater Pollution

When you take a minute to think about it, preventing stormwater pollution is directly connected to chores we do related to the upkeep and care of neighborhoods, homes and vehicles.  Promise to choose two Best Management Practices or BMPs in order to improve and protect our water quality.  Then choose two more, before you know it preventing water pollution will become a good habit you practice each and every day.

Prevention Menu of Best Management Practice

Neighborhood Care

Don't be a Litterbug!
This includes unintentional littering by keeping a lid on garbage cans and recycling bins each week.

Pick up litter in the neighborhood, especially if you see it in the streets.  Your neighborhood will be better for it and water pollution adverted (as litter is washed down the storm drain).

This especially means NO CIGARETTE BUTTS thrown out car windows or dropped on the ground, which is littering, plain and simple.  Cigarette butts are paper wrapped in plastic that doesn't break down in nature.  When washed down the storm drain they become "food" that in turn harm, rather than feed, fish, frogs and other living creatures who live in or near the water.

Adopt a Storm Drain
Some community has adopt a storm drain program, however if your community does not have one that doesn't mean it can't be adopted.  Adopting entails making sure your storm drain is free of debris, like litter, leaves and grass clippings!  This not only helps protect water quality but reduces the likelihood of localized flooding on your street.

Make sure your storm drain is labeled "Dump No Waste Drains to Streams" - most communities have either a painted stencil or a metal button that is glued on.  This is a great reminder, especially for neighbors who think the storm drain is a yard waste receptacle to not do that.

Report illegal dumping - especially the neighbor who dumps the grass clippings, or worse cooking oil or vehicle oil down the storm drain.  They may think it's innocent enough, however they should know better.  Once reported, most communities have a notice that goes out to the entire neighborhood reminding all neighbors that storm drains are a direct connection to our waterways.

Yard Care

Don't go "bare" for very long.  If you have spots in your yard without grass, that area is subject to erosion when it rains.  Reseed those spots and while your at it - reseeding your entire yard on a regular basis (once every year to every two years).  When you do reseed, try aerating first and add a 1/4" to 1/2" layer of compost before seeding to keep your turf healthy and strong.

Got grass clippings?  Mulch mowing is a great way to go (mow without collecting the grass clippings) to return nutirents back to your yard.  If you mulch mow, make sure the mower faces the yard at all times - not the street or driveway.  If grass clippings do end up on the street or on the drive, sweep them up, if not you - they can be swept away with the next rain and clog up the storm drain - generating a awful stink as they slowly decompose.  If you do bag your grass clippings, consider backyard composting to turn grass clippings into a great soil amendment.

Before fertilizing your yard test your soil to determine the nutrients it needs - most soil in Iowa has plenty of Phosphurs in it already - double check to make sure if you need it or not.  If it doesn't need it - purchase fertilizer that is Phosphorus or "P" Free.  Phosphorus is the "P" in the NPK (N = Nitrogen and K=Potassium) and is the middle number on fertilizer bags.  "P" is the leading cause of algae growth in detention basins and Iowa lakes.  The less we use, the more likely your neighborhood detention basin will be algae free.  If you do fertilizer, avoid overfertilizing - let your soil test determine how much of what you apply on your lawn!

The same goes for herbicides and all pesticides and fertilizers - the least toxic product as possible (some weeds are killed by hot salt water), buy only what you need and use it all up.  If you have extra, be sure to safely recycle any leftover product with your local Regional Household Hazardous Material Collection Center rather than disposing of them in your trash can.

Moving into Fall, and your community has a leaf collection program - rake leaves rake them TO the curb, not in the streets.  This keeps your storm drain free of clogs and debris while making it easier for the collection crew to pick-up leaves and take them away for you.

Vehicle Care

Working at the car wash, car washin'...If you plan to wash your car or truck do so on a grassy area, allowing the water to absorb into the ground rather than draining away down the street and into the closest storm drain.  The soap you choose matters as well - as with lawn fertilizers, try to go "P" free here too.  The best bet though is going to a car wash - they send all wash water down the sanitary sewer for treatment, instead of the storm sewer and no treatment.

The rainbows seen in parking lots puddles after it rains is evidence of hydrocarbons (oil leaks) from cars and trucks.  To be sure your vehicle doesn't contribute to water pollution make sure all leaks are fixed in record time and keep our streets, driveways and parking lots clean.

Dispose of oil and other automotive fluids in a safe manner - never dump on the ground, down the storm drain or in the garbage can.  You should be able to recycle any oil and other automotive fluids for free at most retailers who sell them.  Check with your neighborhood store, like AutoZone, NAPA or O'Reilly's to see what can be recycled with them for free (includes lead acid batteries, anything metal and other fluids.)  Never store these items outside, uncovered exposed to rain or other water.

Pet Care

Pick up after your pet, whether it is on a walk, in a park or in your yard.  It's the right thing to do, people won't step in it and you prevent the poop from entering our streams - where kids usually play!  Once you pick it up dispose it in the trash can or flush it down the toilet.  Never throw the bag of poo down a storm drain, that is considered illegal dumping and should be reported to your community if you ever see it happening.

Pool and Spa Care

Summer is over and the pool and spa needs to be emptied....when draining the pool and spa be sure to contact your local city to find out how they want you to dispose of the water.  Some may recommend that you run the chlorinated pool and spa water across vegetation first.  It will slow down the flow, allowing for bacterial removal and the chlorine (which can harm aquatic life) to dissapate before it reaches the closest storm drain.  Others may want you to discharge the water to the sanitary sewer.  Always recycle outdated or unwanted pool chemicals with your local Regional Household Hazardous Material Collection Center.
