Toluene is a member of the benzene, toluene, ethylbenzene, and xylene (BTEX) group of pollutants, which are volatile organic compounds (VOCs). VOCs are certain compounds that participate in atmospheric photochemical reactions; in other words, VOCs aid in smog and ground-level ozone formation. Though VOCs are released by plants, they are released in much greater quantities by anthropogenic sources. Toluene is a component of paint thinners, adhesives, some inks, rubber, pesticides, and nail polish, is an additive to gasoline, and is used in leather tanning. It most commonly enters surface or groundwater through petroluem spills, which accounted for 90 percent of all toluene spills in 1993. Additionally, the EPA found that the pollutant was present in the water or soil at 63 percent of domestic hazardous waste sites in 1991.
Fish and other aquatic organisms are sensitive to both acute and chronic toluene exposure, which can cause major nervous system and neurological damage. Toluene is also most hazardous when absorbed through the skin, which is the most common point of entry for aquatic organisms.
How You Can help

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.
