Ways to Help Reduce Polluted Stormwater

How Can YOU Prevent Stormwater Pollution?

By the WNY Stormwater Coalition

 

What is stormwater?

Stormwater is water from rain or melting snow that does not soak into the ground. It flows from rooftops, over paved areas, bare soil, and sloped lawns. As it flows, stormwater runoff collects and transports animal waste, litter, salt, pesticides, fertilizers, oil & grease, soil and other potential pollutants.

Rain and snowmelt wash pollutants from streets, construction sites, and land into storm sewers and ditches. Eventually, these empty the polluted stormwater directly into streams and rivers with no treatment. This is known as stormwater pollution.

Polluted stormwater degrades our lakes, rivers, wetlands and other waterways. Nutrients such as phosphorus and nitrogen can cause the overgrowth of algae resulting in oxygen depletion in waterways. Toxic substances from motor vehicles and careless application of pesticides and fertilizers threaten water quality and can kill fish and other aquatic life. Bacteria from animal wastes and improper connections to storm sewer systems can make lakes and waterways unsafe for wading, swimming and fish consumption. Eroded soil is a pollutant as well. It clouds the waterway and interferes with the habitat of fish and plant life.

The USGBC has approved new LEED v4

The united States Green Building Council (USGBC) has been working on new updates to their rating system and those changes will be demonstrated at the Greenbuild conference in November 2013. The council debated on the pros and cons of the changes and according to Tristan Roberts finally “members, with 86 percent of the voting body voted in the affirmative.”

 

This will be an exciting time at the conference!

Using Pervious Concrete to Achieve LEED Points

By: Erin Ashley, PhD

As appeared in Concrete InFocus, a publication of NRMCA, Winter 2008

“Pervious concrete is a unique and innovative means to manage stormwater. When pervious concrete is used in building site design, it can aid in the process of qualifying for LEED Green Building Rating System credits.”

“Pervious pavements function like storm water retention basins and allows the stormwater to infiltrate the soil over a large area, thus facilitating recharge of precious groundwater supplies.

Pervious concrete has been used successfully in many types of construction on applications such as parking lots, streets, plazas, nature trails, and walkways. While pervious concrete can be used for a surprising number of applications, its primary use is in pavement. Pervious concrete is a performance-engineered concrete made with controlled amounts of aggregates, water and cementitious materials to create a mass of aggregate particles cover with a thin coating of paste. A pervious concrete mixture contains little or no sand, creating a substantial void content. Using sufficient paste to coat and bind the aggregate particles together creates a system of highly permeable, interconnected voids that drains quickly. Typically, between 15% and 25% voids are achieved in the hardened concrete, and flow rates for water through pervious concrete are typically around 480 in./hr (0.34 cm/s), although they can be much higher. Both the low mortar content and high porosity also reduce strength compared to conventional concrete mixtures, but sufficient strength for many applications is readily achieved.”

“Why use Percoa?”

According to the U.S. Environmental Protection Agency (EPA), about 90 percent of surface pollutants are carried by the first 1-1/2 inch of rainfall.

Storm water drains don’t typically channel this polluted runoff to treatment facilities, but instead convey it directly into local water bodies. Polluted runoff, if not diverted, ends up in our waterways along with water that is heated as it flows over paved surfaces and into the watershed. The concern being that temperature change in a stream or lake can harm aquatic plants and wildlife.

The use of pervious concrete (Percoa Slabs)is a widely accepted as an effective material to capture, filter and disperse storm water runoff and is among the Best Management Practices (“BMPs”) recommended by the EPA as well as by other agencies

Percoa’s proprietary, patented products can be used for new construction or to retro-fit existing concrete or asphalt surfaces such as storm water runoff basins, parking lots, driveways, walkways, patios, and a myriad of other surface applications where water runoff is a concern. Percoa combats the harmful effects of pollution entering the water supply, and helps reduce temperature changes.

Blowing in the wind: Using Dust to Advertise

Element Six Media, I Love them!

As a green company we not only want to clean up our water ways,
we also want to make decisions around other aspects of our company that are
green and sustainable too.

I started reading about Element Six last year and they still
impress me with their ingenious ways of incorporating green products into advertising.

Here is a sample of one of their dust designs,

Please check out their website for more examples of what happens
when creativity is paired with sustainability.
