I know many people are aware that all tap water of course must meet certain standards set by the Environmental Protection agency. However, a lot of people are not aware that the test results must be released upon request by the treatment plants/municipalities. Most of them maintain an on line site that posts at least the annual results, if not the monthly or quarterly reports. Most of these facilities also test for many more contaminants that they are required to test for. Below is a sample result posted by the company that processes the municipal water in Fairbanks, Alaska. As I have been working on a fish hatchery in Fairbanks, Alaska off and on all summer, I had an opportunity to do a walk through. It has improved vastly since the city quit operating it and sold it to a commercial venture.
