Why Healthy Water?
Although water varies by geography and source, many municipal water supplies contain some combination of suspended heavy metals, pharmaceutical residue, and biological organisms within the residential water used for drinking, cooking, and bathing (see Water Quality Reports for detail). Scientific studies have linked heavy metal, chemical residue, and pharmaceutical bi-products in municipal drinking water supplies to increased risk of thyroid issues, cancer, diabetes, and autism (see publications from sources unrelated to Water4 Systems for detail).

Studies have specifically identified links between common municipal drinking water and leukemia, skin cancer, type 2 diabetes, prostate cancer, breast cancer, and colon cancer. Even the standard plumbing materials found in the post-treatment water supply present known health risks, including arsenic, asbestos, trichloroethylene, and lead (see publications from sources unrelated to Water4 Systems for detail).

Pharmaceutical residue in the water supply is receiving increased recognition as a problem. The U.S. Geological Survey tested surface water in 30 states, looking for antibiotics, antidepressants, steroids, analgesics, reproductive hormones, and hypertensive and cholesterol-lowering drugs, totaling of 95 different organic wastewater contaminants. Pharmaceutical residue in drinking water is particularly problematic because it is designed to work in low concentrations. The USGS found at least one contaminant in 80 percent of the water samples taken from 139 streams in 30 states. The Associated Press reviewed scientific studies and government databases and reported the identification of pharmaceutical residue in the drinking water of at least 25 major metropolitan areas (Guidotti, 2013).

Officials in Philadelphia said testing there discovered 56 pharmaceuticals or byproducts in treated drinking water, including medicines for pain, infection, high cholesterol, asthma, epilepsy, mental illness and heart problems (for current detail, see 2014 Philadelphia Water Quality Report). Tests of municipally treated drinking water, supplying 18.5 million people in Southern California, detected anti-epileptic and anti-anxiety medications (for more information, see LA DWP’s response).

A USGS test of drinking water from a Passaic Valley Water Commission drinking water treatment plant, which serves 850,000 people in Northern New Jersey, revealed a metabolized angina medicine and the mood-stabilizing carbamazepine. Tests of San Francisco’s drinking water detected a sex hormone while similar tests in Washington, D.C. and surrounding areas yielded for six pharmaceuticals (Donn, Mendoza, & Pritchard, 2008).
