Sulfates are compounds containing sulfur that cycle throughout the environment as part of natural biogeochemical cycles, which means they can enter aquatic ecosystems naturally. Methods of entry into freshwater ecosystems include saltwater intrusion, sea spray, and sea level rise. However, the majority of sulfates originate from surface runoff and air pollution, which is deposited into rivers through acid raid. Sulfates are often used in fertilizer, so pollution near these areas is the worst.
Sulfur compounds can have many detrimental effects on freshwater ecosystems. For instance, they promote the conversion of mercury into its most toxic form, methylmercury, and stimulate sediments to release nutrients, causing eutrophication. Some of the compounds themselves are also toxic to organisms within freshwater environments.

If you live or work next to a waterway, leave a 35′ to 100′ no mow zone on its banks. Allow natural and native plant growth in this buffer area or plant native trees, bushes, and groundcover. This vegetation can filter pollutants before they reach your waterway and provide other water quality benefits that far exceed those of a mowed lawn. Native plants and grasses require less watering and fertilizer and also provide important habitat for native species of wildlife.

Impervious or impermeable surfaces, like pavement, contribute significantly to polluted stormwater runoff and alter stream flow habitat. If you've got excess pavement you'd like removed, consider a de-paving project with the Compact. Elsewhere, ensure that your downspouts drain to vegetation, gravel, or rainbarrels, rather than impervious surfaces. If you constructing or repairing your driveway, pervious pavement allows stormwater to infiltrate and filter through the ground. If you can’t do the whole drive, consider making only the portion closest to the street pervious.

Participate in community planning efforts and advocate for relevant measures that improve or protect water quality. Write to your elected official and let them know this is concern or invite them to speak about the impairment with your home-owners association. When elections come up, vote for candidates who will address the problem and hold them accountable to their promises. Support local watershed / environmental associations.
