Preserved wood is widely used to construct piers, docks, buildings, decks and walkways in or over aquatic and wetland environments. Of course, protecting the water quality and the diversity of life found in lakes, streams, estuaries, bays, and wetland environments is the industry’s No. 1 goal.
WWPI recommends when specifying preserved wood for these types of applications, request it conforms to WWPI's Best Management Practices (BMP) program. The BMPs are recommended guidelines for the production and installation of preserved wood products destined for use in aquatic and wetland environments.
The guidelines were developed through a consensus process, based on the core philosophy of preservative minimization. Both environmental and economic concerns support the goal of placing enough preservative into a product to provide the needed level of protection while minimizing use of the preservative above the required standard minimum in order to reduce the amount potentially available for movement into the environment.
