A recent water quality story caught our eye out of Southern Nevada – mysterious brown foam found floating on Lake Mead.
According to an Associated Press Report, officials urged people to avoid the Overton Arm, a northern area of the lake, when several dozen carp were found dead in the foam, which extended for about eight miles from the mouth of the Virgin River to Echo Bay.
Water quality testing is underway, and the Nevada Department of Wildlife is investigating the fish deaths, according to the article, but the Southern Nevada Water Authority, monitoring water quality at two intakes, hasn’t found any problems.
The article quotes Southern Nevada Water Authority Spokesman Bronson Mack as saying no pollutants have been found at the intakes.
“It really is a massive body of water, and that’s one benefit from a drinking water perspective,” he told the Associated Press in regards to dilution, adding that water from the Overton Arm takes about a month to make it to the intakes.
In an www.8newsnow.com story, there was speculation of a virus killing the fish and an increase in water temperatures killing off algae to create the foam, meaning the two could be unrelated.
But in an editorial on lasvegascitylife.com, Peabody Award-winning reporter George Knapp raised some concerns.
“I would probably feel a bit better about drinking tap water from the lake if I hadn’t heard so many similar statements from our water officials in years gone by. SNWA and the Water District have spent millions over the years on touchy-feely TV commercials that assure all of us how great our water tastes and about all of the incredibly rigorous tests which are conducted thousands of times each month to ensure that every drop is perfectly safe,” Knapp wrote, referring to missed pollutants in Lake Mead like perchlorate that went undetected by testing for decades.
This will be an interesting story to follow, and one that drives home the importance of water quality monitoring.
