The Pacific Northwest Pollution Prevention Resource Center (PPRC) has completed a series of resources (below) on preventing zinc pollution. Please take a moment to view them and pass them on to any contacts – businesses, site managers, compliance officers, friends – who you think might benefit from this information.


Zinc is a troublesome metal for a lot of businesses trying to prevent stormwater pollution. Because the metal comes from so many sources, businesses likely need a variety of site-specific solutions. Which solutions are working in the Northwest? Note to you boatyards out there: the Port of Port Townsend plays a major role in the film!

Emerging Best Management Practices (pdf documents)

Biochar as Filtration Media

Biochar is a promising, versatile, and affordable filtration material. Why is it so effective? How widely is it being used in the Northwest? What do we know and not know about its ability to filter pollutants, especially heavy metals?

Mitigating Zinc in Boatyards

There over 55 boatyards in the general Puget Sound area. Many of these boatyards have zinc in their stormwater above permit levels. What cost-effective solutions are boatyards employing to control their zinc sources?

Street and Surface Sweeping to Reduce Stormwater Pollution

While sweeping is a simple idea, things get complicated fast when you’re faced with preparing a specific plan and budget. After all, what is Vacuum Sweeping? How about Regenerative Sweeping? Do you do things differently in the “wet” versus the “dry” season? And how often should you sweep?

Addressing Galvanized Roofing

An often over-looked, or maybe under-looked, aspect of controlling zinc is coating bare or corroded galvanized roofs. Can coating roofs act as an effective method of reducing zinc pollution? What best management practices should businesses know to effectively coat roofs?
