Cancer patients and their families need support as they fight a horrible disease. Unfortunately, the very drugs that are saving their lives have the potential to hurt their families, especially the very young. Handful of cornerstone chemotherapeutic drugs, are genotoxic (directly attack DNA) and pass through cancer patients as active chemicals in their urine, feces, vomit, saliva, and sweat. The chemicals are known to cause cancer, birth defects, and miscarriages in others. The dangerous chemicals cannot be removed by wastewater treatment or water purification. Preventing the active chemicals in patients' wastes from contaminating our households, our land and entering our water is the best way to protect our families and drinking water supply.
