LADWP Still Trying to Control Dust Left Behind by LA Aqueduct

New, 9 comments

LA's Department of Water and Power thinks it has a new plan to deal with the insanely expensive dust mitigation up at Owens Lake. The lake, about 200 miles north of the city, went dry after the construction of the LA Aqueduct 100 years ago--the aqueduct brought drinking water from the Eastern Sierras down to the growing Los Angeles area (you know, like in Chinatown). Attempts to flood the lake to keep blowing lakebed dust from wreaking havoc with the air quality in the Owens Valley have cost $1.2 billion over the last 12 years--or about 15 percent of every LADWP customer's annual water bill. But even after all of that, the dust hasn't been completely controlled, and late last year LADWP sued to try to get the air quality board to accept that the status quo was good enough. According to the Daily News, LADWP's new plan--which, with a pricetag of $600 million to $1 billion, isn't exactly thrifty--would use gravel and brine or another low-evaporation liquid to control dust, among other measures. The idea is that this solution would use less water and would be paid for in part by LADWP buying less water from other sources.
