Buy bottled water You may be able to reduce arsenic levels in your drinking water by using bottled water. Bottled water is subject to the same testing and regulation that is required of public water systems. Be sure that levels of arsenic and other contaminants in the bottled water you choose are lower than levels in water from your current water supply. The bottling company should be able to provide the results of testing their water. Private wells should be tested at least once a year for bacterial safety.
Spring is usually a good time to test.
It's also a good idea to test for bacteria any time water changes in taste, odor, or appearance. For more information go to Bacterial Safety of Well Water. Well water should also be tested every year or two for indications of nitrate contamination. If nitrate has been found, testing should be more frequent. Always test the water before giving it to a newborn.
