The Sierra Club California/Nevada Desert Committee newsletter reports on several environmental issues affecting the desert region. A chromium 6 plume in Needles, California is located just 55 feet from the Colorado River, threatening Southern California's drinking water supply. The source is a Pacific Gas & Electric natural gas facility. The newsletter also discusses efforts to control air pollution from dust storms at Mono Lake and the Desert Committee's work collaborating with Native American tribes to protect desert lands and cultural resources.
