Who should I contact for testing of soil and air quality around our house? Recently we have lost our two dogs to cancer and a few years earlier our cat, also to cancer. My wife and I are very concerned that this could all be related to the environment in which we live. Is our soil contaminated? Is the pollution from the Expressway near us having an effect, etc ,etc. (we live in Sydney, Australia)

So my question (s) is, who do I see about getting tests of soil and air quality? Is it expensive, Is it worth it? 20% 1 Vote
