Toxic Chemicals in Puget Sound

List of potential actions


Chemical of Concern Major Current Manmade Sources Possible Actions for Reductions
ArsenicIndustrial air emissions Maintain existing permit controls.
Pressure-treated woodContinue ban for most non-structural uses.
Roofing materialsPossible opportunity for source control, but more data needed on extent of releases.

CadmiumRoofing materialsPossible opportunity for source control, but more data needed on extent of releases.

CopperLawn and garden pesticides More data needed on actual pesticide use.
Residential plumbingContinue to implement lead and copper rule.
Brake padsContinue to implement legislation enacted to reduce copper in brake pads.
Roofing materialsPossible opportunity for source control, but more data needed on extent of releases.
Boat paintContinue to implement legislation enacted to reduce copper in boat paint.

Lead Ammunition and hunting shot Implement Chemical Action Plan and enforce existing rules.
Fishing sinkers and wheel weights Implement Chemical Action Plan and enforce existing rules.
Roofing materialsPossible opportunity for source control, but more data needed on extent of releases.
Aviation Implement Chemical Action Plan and enforce existing rules.

MercuryImproper disposal of consumer productsContinue to implement Chemical Action Plan and enforce existing rules.
Crematoria and industrial air emissions Continue existing permit limits.

Zinc Roofing materialsPossible opportunity for source control, but more data needed on extent of releases.
Vehicle tire abrasion Investigate source where it poses local concern.

PCBs Electrical equipment spills and leakage Continue programs for management and disposal.
Residential trash burning Continue enforcing existing ban.
Building sealant (caulk) volatilization and abrasion Investigate source where it poses local concern.

Flame retardants (PBDEs)Furniture, computer monitors, and other components of residential and commercial indoor environments Enforce ban on new products but consider control actions to reduce the release from existing products.

PCDD/Fs Backyard burn barrels Continue enforcing existing ban.

DDT None apparent Investigate source where it poses local concern.

PAHs Wood smoke from woodstoves and fireplaces Continue change out programs, investigate catalysts/capture devices, promote alternatives to wood heat.
Vehicle exhaust Anti-idling programs, continue/expand engine retrofits for private sector engines, enforce existing vehicle controls.
Creosote-treated piling, railroad ties, and utility poles Control actions needed, gather information to identify highest priority areas.

Phthalates (DEHP)Plastics (primarily PVC) off-gassing Gather additional information on extent of releases.
Industrial, commercial, and institutional air emissions Maintain existing permit controls.
Roofing materials Possible opportunity for source control, but more data needed on extent of releases.

Triclopyr Weed killer useMore data needed on pesticide use.

Nonylphenol Detergents; industrial, commercial, and institutional air emissions More information needed on emissions from these sources and unidentified releases.

Petroleum Motor oil drips and leaks; improper disposal of used motor oil Expand existing education/workshop programs.
Small gas spills during fueling Possible opportunity for source control, but more data needed on extent of releases.
