Frequently Asked Questions (FAQ)

Question:
I am looking for recommendations on filters or other media that can be used on stormdrains and catchbasins to reduce metals and hydrocarbons in stormwater.

Answer:
Please visit our website at www.BMPLA.org where there's an FAQ page and a Yellow Pages data base. Los Angeles County, DPW does not recommend specific products. In fact the Yellow Pages disclaimer reads:
The BMP Yellow Pages are a list of proprietary and nonproprietary products, activities, and services that are meant to improve or eliminate pollution associated with urban runoff and stormwater. The phrase "Best Management Practice" is a common term used in Federal, State, and local regulations to label these types of products, activities, and services. Usage of the term does not imply that some products, activities, or services are better than others, nor that the County of Los Angeles evaluates or decides which product, activity, or service should be listed. The inclusion of manufacturers, consultants, products, or services on this list in no way represents an endorsement or guarantee of effectiveness as a result of the use of these products, nor for any compliance issues regarding the Americans with Disabilities Act. Please contact the vendor and follow the manufacturers' specifications for preparation, installation, and maintenance of these products.

You can also visit our LID practices web page (http://ladpw.org/wmd/dsp_LowImpactDevelopment.cfm). In addition, you could check back at the BMPLA.org page in the near future, where we'll list the proprietary products that are acceptable, with conditions, for maintenance and use by DPW.
