The EPA has long monitored the amount of arsenic and other contaminants in the public water supply. Despite their efforts, and the efforts of city municipalities, water cleanliness and health remain a challenge.
Lead and copper enter drinking water primarily through plumbing materials. Exposure to lead and copper may cause health problems ranging from stomach distress to brain damage. On June 7, 1991, EPA published a regulation to control lead and copper in drinking water. This regulation is known as the Lead and Copper Rule (also referred to as the LCR or 1991 Rule).
The treatment technique for the rule requires systems to monitor drinking water at customer taps.If lead concentrations exceed an action level of 15 ppb or copper concentrations exceed an action level of 1.3 ppm in more than 10% of customer taps sampled, the system must undertake a number of additional actions to control corrosion. If the action level for lead is exceeded, the system must also inform the public about steps they should take to protect their health and may have to replace lead service lines under their control.
To fend off arsenic and other contaminants in drinking water, the public is encouraged to invest in an effective water distiller.
Proper home and counter top distillation minimizes toxins and provides your family with the cleanest water available.


Most people understand the serious risks to your health from the inhalation of dangerous chemicals and contaminants. But, many more people don't know the hazards some contaminants pose to many Americans' drinking water.
