Your local water supply company is required by law to run tests on the water supply and have on hand for anyone who asks (and usually supply with your bill annually) copies of the results of those tests showing what is contained in the water. Ours came in the last utility bill and I was surprised to find that 4 locations had fines and violations for high
nitrate levels already this year. While the main water supply is only at 11 for nitrates so far the farmers are not starting to add chemicals to the ground around here yet and this is scary. By midsummer after the fertilizers and weed killers and all have been added and the rains have washed them into our water our nitrates and other chemicals can and probably will reach harmful levels. Ammonia in the water supply (I read on a site that keeps track of water testing) can mean that there were battlefields or some sites nearby that contained bodies buried without proper processing. (many, many years ago) and the chemicals used to treat the water (like
chloramine and such) are meant to counteract the harmful effects of any type of things that appear in the supply of the tap water that we drink. I was horrified to find on the bottom of the report of our water supply though a warning that babies under 6 months old could be irreversibly harmed by drinking water with nitrates at the levels found at the 4 locations that were in violation status in our area. It gave the locations but I am wondering how long they may have drank the water at those levels before they were notified.
It also makes me wonder if any fish were in those locations and how many died. Infants under 6 months of age would certainly be as sturdy as a fish in many cases and not forced to live in the water 24 hours a day 7 days a week.
