(AP) - State environmental officers worried about possible contamination have ordered residents and businesses in a community near Winnemucca to boil their water before drinking it, including the Grass Valley Elementary School.
The Nevada Division of Environmental Protection issued the order Wednesday for the approximately 950 people who live in Humboldt County's Gold Country Estates after a second round of tests confirmed the presence of coliform bacteria.
Officials say that suggests the system could be contaminated with E. coli.
E. coli comes from human or animal wastes. It can cause diarrhea, cramps, nausea, headaches and other symptoms. Exposure may pose a special health risk to infants and young children.
The order will remain in place until additional tests confirm the water is safe to drink.
