What can we do to push awareness of the fact that water quality is a public responsibility, at home and at work?
Your question is similar to a previous one asked by nick_at_rh2o about What do you see/do to remove trash from the waste stream?. The response is a bit the same, although yours is more general and can be link to trash as well as chemical products, FOG, that are dumped in the sewers, toilet, drains. The response is not all on communications campaign and public outreach. Portions of it is also due to the 10s of thousands of new chemical produced every year by the industry. That takes more of a regulatory approach as well. This goes though more of a lobbying approach so that regulators are aware and act upon the chemical produced and their proper disposal. it is a complex question.
As an operator, you can work with your community on awareness. It takes time, but it works on the long run. On the regulatory side, you can work with your regional/national association to make your voice heard.
