Local water outlets including municipal water systems do not deliver chemical-free drinking water to their respective populations. The federal government doesn't require states to remove chemical contaminates from water. If they did this would cost states a fortune. So states are only required to REDUCE chemical contaminants in tap water. Our space-grade tools and equipment filter and purify water, no matter how contaminated. Our commercial & industrial water purifiers utilize our medical grade electrodes, and through advanced forms of electrolosys treat water without chemicals.
