In an online petition that has received about 2,000 signatures, Callie Loudenber is asking local and state officials to pay for bottled water and filters for El Paso County residents whose water she calls "dangerous." Prefluorinated chemicals - compounds used in a wide variety of common products that include cookware and firefighting materials - have been found in Security, Widefield and Fountain at levels exceeding the Environmental Protection Agency's recommendations. In May, an EPA health advisory indicated that water with PFC levels at more than 70 parts per trillion could be unsafe.
