Without the EPA, we have no protection against contaminants like arsenic in our drinking water. Recently, fracking is posing a risk as it contaminates groundwater.
Be on the safe side for yourself and your children, install a water filter on your sink and get some clean glass bottles and bottle your own drinking water. I've done this for years and enjoy the inexpensive method of having clean drinking water. Don't use plastic bottles and only infrequently drink from bottled water in plastic containers. They may have trace amounts of carcinogens. Plastic is also bad for the environment. Use glass which can be cleaned and sterilized easily.
