In urban areas, chlorpyrifos receives significant use. Environmental releases of chlorpyrifos can occur during handling, mixing, loading and applying activities. The urban portion of these problems is at least as significant as the agricultural portion. EPA needs to consider cumulative effects of chlorpyrifos and other substances present in surface waters. The cumulative use of organophosphate pesticides contributes to surface water toxicity problems.

The wine grape industry can find ways to maintain most of its vigor without putting the environment and our health at risk. Imidacloprid must not be allowed to reach groundwater or to run off into waterways. I and II acute pesticides should be strictly avoided as well.
