Wood Preserving Objectives
• List three major chemical preservative systems
• List key chemicals associated with wood preserving
• Describe the pressure treating process
• List major modes of release to the environment
• Identify analytical methods useful for detecting wood preservative contaminants in the environment

Wood Preserving Overview
• Active in U.S. for over 100 years• Produces treated lumber and wood
products which resist degradation • High percentage of small businesses• Many facilities closed, abandoned or failed to comply with
“new” industry-specific RCRA regulations (1990)– wastewaters listed as hazardous waste – Drip pads and other improvements required

Process Overview
• SIC: 2491, NAICS 321114
• Used by construction, railroad, and utilities industries
• 6.5 billion board ft / yr (2000)
• 486 U.S. facilities (1992)
• 307 employ 20 or fewer
• 90% by pressure treating process

Major Chemical Preservative Systems• Organic (oil-borne) Creosote (15%) Pentachlorophenol (PCP) (6%) systems
• Inorganic (water-borne) (78%) Chromated copper arsenate Ammoniacal copper-zinc-arsenate (ACZA) Ammoniacal copper arsenate (ACA) Ammoniacal copper quarternary (ACQ)

Key Chemicals
Arsenic - “CCA” constituent, toxic and prevalent
Oil – diluent/lubricant/fuel, contains VOC’s, including BTEX
Creosote – preservative, mixture of SVOC’s, a.k.a. “cancer in a bucket”
Chromium – “CCA” constituent, toxic (especially Cr+6)
PCP – preservative, chlorinated SVOC, solid unless “oil-borne”
Zinc – “ACZA” constituent, less toxic, less prevalent
Dioxins / furans – toxic chlorinated SVOC “family”, 2,3,7,8-TCDD “Godfather”
Copper – “CCA” constituent
Diesel oil – preservative diluent
