Vancouver, Wash. - With fireworks going on sale next week, Clark County reminds residents they need to clean up fireworks debris to keep harmful pollutants out of our creeks, rivers and streams.
Fireworks contain metals, nitrates and sulfur, along with paper, plastic and other materials. If fireworks residue is not swept up after Fourth of July festivities, rain will wash these pollutants into nearby storm drains.
In some areas, storm drains and pipes carry untreated stormwater directly into waterways, where pollutants harm fish and other aquatic life.
