In this photo made on Wednesday, Dec. 15, 2010, clear treated water flows from a tap continuously for random testing at the intake facility of the Beaver Falls Municipal Authority in Beaver Falls, Pa. The natural gas boom gripping parts of the U.S. has a nasty byproduct: wastewater so salty, and so polluted with metals like barium and strontium, most states require drillers to get rid of the stuff by injecting it down shafts thousands of feet deep. Not in Pennsylvania, one of the states at the center of the gas rush. There, the liquid that gushes from gas wells is only partially treated for substances that could be environmentally harmful, then dumped into rivers and streams from which communities get their drinking water.

In conjunction with the Nevada Division of Environmental Protection and the Nevada Bureau of Safe Drinking Water, the Big Bend Water District (BBWD) has lifted the Boiled Water Order for all water users in Laughlin, Nev.

   Water quality sampling and testing has shown that the water being provided to Laughlin residents meets or surpasses safe drinking water standards.
Residents in Laughlin and areas serviced by the BBWD may now resume normal water use. As an added precaution, homeowners may flush their home plumbing system. Below are some general flushing recommendations for residential properties.
* Cold Water Flush: Run all cold water taps for three minutes. If you have a single-lever faucet, set it to run the cold water first.
* Hot Water Flush: To clear water heaters of all water, utilize the drain located at the bottom of the heater. If you are unable to drain the entire water heater, flush hot water for a minimum of 15 minutes for a typical household 40-gallon hot-water tank, 30 minutes for an 80-gallon hot water tank or larger. Bath tubs provide a great faucet for flushing as the flow is unrestricted from an aerator.
* Dishwashers: After flushing hot water pipes and water heater, run dishwasher empty for one full cycle.
* Ice cubes: Automatic ice machines should be emptied of ice made during the boil order and run through a 24-hour cycle, discarding the ice to assure flushing of the icemaker supply line. For medical, dental, and foodservice establishments, please refer to the guidance from the Southern Nevada Health District.
* Refrigerator water-dispensing machine: Water dispensers from refrigerators should be flushed by at least one quart of water. If unsure of your dispenser’s capacity, refer to manufacturer specifications.
* Humidifiers: Discard any water used in humidifiers and any medical or health care devices. Rinse the devices with clean water. Consult a heath care professional if appropriate.
Flushing activities should only require about 100 gallons of usage. Because water is billed in thousand-gallons, this use will not significantly impact customer water bills. Furthermore, any water flushed through indoor fixtures will be reclaimed and recycled.
