Is Rust putting more than just Iron into your stormwater?

Have you ever tested the water running off the rusty metal on your site?  Like most you probably just think of rust as adding to your Iron problem but what else is really in that metal that is rusting?

Here is one example of a very small amount of rust water deluded with the same water used for the pre rusty test:

ug/L Pre Rust Post Rust % Increase
Aluminum 376 1290 243%
Copper 2.46 207 8315%
Iron 702 452000 64287%
Lead 0.341 4.76 1296%
Zinc 94.2 222 136%

Catch Basin Insert Solution


Northwest Stormwater Management has developed Stormwater Catch Basin Filters designed to capture typical pollutants that impact storm water drainage systems.  Now with a solution to utilize EarthLite™ Stormwater Filter Media!

The unique design of the Catch Basin Filter is made up of an Adsorb-it filter fabric that is packaged in a hi-strength screen basket attached to a heavy-duty stainless steel frame that allows normal flow of storm water in excess of 100-gpm for extended periods, allowing pollutants such as hydrocarbons, fats, oils, grease (FOG), sediments and silts, as well as heavy-metals such as zinc, copper and lead to be captured and filtered without inhibiting water flow.

The installation of the Catch Basin Filter is a simple process requiring no structural modifications to existing drainage structures, and are an EPA approved Stormwater Best Management Practice (BMP), providing effective Non-Point Source Pollution Prevention and long-standing remediation.
