Private Water Supplies

Over 19 million American households and cottages rely on private wells. Tens of thousands more rely on lakes, streams, and other surface water sources. Unfortunately, not all of them have a UV water disinfection system protecting them from harmful microorganisms.

While nation-wide studies do not exist, smaller scale studies have commonly found that between 20 and 40% of wells in any given region suffer from E.coli  and/or coliform bacteria at any given time – not to mention the countless other microorganisms that may be in a water supply.

The fact is that the quality of well water can vary from day to day and from year to year. In the short term, things like heavy rainfalls or snow melt can affect water quality. In the longer term, quality may be affected by distant contamination sources, earthquakes, and other factors.  Water that has been safe for years will not necessarily be safe tomorrow.

Municipal Water Supplies

Around the world, governments invest heavily in order to assure the safety of the drinking water for their citizens. However growing pollution and the costs of maintaining distribution networks make boil water advisories increasingly inevitable. Beyond the inconvenience they cause, such advisories are a clear warning that the clean water we've taken for granted is becoming a scarce resource. In May, 2000, 220 communities in British Columbia and 250 in Newfoundland faced boiled water advisories.
