3: How do you account for these levels being so high?
Land releases
total off-site transfers
total production-related waste
air releases of recognized carcinogens

better here in San Diego? Explain.
Water releases of suspected carcinogens
Water releases of suspected developmental toxicants

I feel disturbed that one of the 'greenest cities' have high amounts of toxic pollutants. I was not surprised at all, because San Diego are something having trash at street, trees are not green, but most of our air toxicants are one of the worst in the US. Some potential solutions are to use alternatives that are not toxic, like using white vinegar and borax rather than stuff like bleach and windex
