Chemical-munching bacteria to make cleaner water in Riverside area
Bacteria already in the ground could clean drinking water in the Inland Empire. According to Janet Zimmerman at the Press-Enterprise, water districts are developing system whereby water is pulled from well, run past these bacteria, which eat perchlorate and nitrate and VOCs, volatile organic compounds (well, digest them), producing nitrogen gas which can get released to the atmosphere with oxygen. Then they zap out the waste bacteria, chlorinate the mess and bam! Drinking water.
Though biological treatment is more expensive up front, about $4.2 million vs. $3.8 million for ion exchange, it saves money in the long run because it can treat high levels of contaminants and treats multiple chemicals in a single process. Biological treatment is about $238 per acre-foot of water, compared to $254 for ion exchange, according to a 2009 study by the Department of Defense.
Morning greens: Terminator and 'Avatar' director fight Prop 23
Governor Schwarzenegger and James Cameron launched a PSA against Prop 23, reports Grist. The Avatar director recently contributed $1 million to fight Prop 23.
The Westside Subway Extension will run down Wilshire Blvd. to Westwood, decided the Metro board yesterday. “If all goes as planned, construction will begin in 2013 after an environmental impact review,” reports LA Times. When will it be finished? Depending on various funding scenarios, sometime between 2022 to 2036, according to Metro’s The Source.
The Metro Board also decided that the downtown Regional Connector will be fully underground. “The 1.9-mile connector would proceed underground via 2nd Street and beneath 1st and Alameda streets. It would include three stations, at 2nd and Hope streets, 2nd and Broadway, and 2nd and Central Avenue,” reports LA Times. That project’s expected to be operational by 2035.
North Cost MLPA a very different tale
I'm interested in the completion of the Marine Protected Areas process - under the state's MLPA law - so I've been reading up on that lately. Here in Southern California, we've got protected areas proposed and under final consideration at the state's Fish and Game Commission. Further up the coast - the North Coast region is still hashing out where protections might go. It's kind of interesting to check in on their process.
As in southern California, the negotiated process has achieved a measure of local consensus. Trouble is, according to a report a few days ago in the Eureka Times-Standard, state biologists aren't impressed with what they've come up with:
The proposal has unachievable goals, scientific shortcomings and unenforceable provisions, Fish and Game marine biologist Rebecca Studebaker said, and the 17 marine protected areas won't meet the requirements of state law without substantial changes.
It was the first showing of the state's position on the proposal developed by more than two dozen fishermen, environmentalists, tribes and seafood gatherers over months of meetings and work. The proposal has been nearly universally supportedlocally, despite the expected economic and social effects of the Marine Life Protection Act.
”These are unable to fulfill the intended purpose of the MLPA,” Studebaker said.
L.A. Sustainability Collaborative bridges gap between academic research and local environmental concerns
I started blogging about environmental issues back when I was in graduate school — in large part to feel more connected to the concrete and pressing real-life issues of the city I live in. Those issued seemed far removed from what I was studying in the ivory tower of academia, though granted, my choice to study obscure modernist poetry probably didn’t help.
But for today’s L.A.-area graduate students who want to intertwine their academic research with pressing real-world problems, the Los Angeles Sustainability Collaborative can help. This nonprofit provides research fellowships to local graduate students interested in studying local environmental issues, ranging from water efficiency, car parking policy, or bicycling opportunities.
“The Collaborative is funding really great projects that benefit the community,” says Alexis Lantz (above), who received a $1000 fellowship to study issues affecting Los Angeles cyclists while a graduate student in Urban Planning at UCLA. Alexis says she’s unlikely to have taken on a study of that scope without the fellowship, which gives students “a real opportunity to do something that’s not purely academic.”
Morning greens: From attorney generals to pregnant cyclists
California’s next Attorney General will play a big role in environment and energy policy “although the race doesn’t particularly hinge on environmental issues,” reports NY Times. “San Francisco District Attorney Kamala Harris (D) is the environmentalists’ clear favorite over Los Angeles District Attorney Steve Cooley (R),” who has received campaign funds from many oil companies.
Tomorrow, the Metro Board will decide on routes for the Westside Subway Extension and the Regional Connector. Read about the recommended routes in LA Times, get tips on participating in the meeting on Metro’s The Source, then weigh in tomorrow.
Should L.A. raise parking fines for repeat offenders? UCLA professor Donald Shoup makes the case for doing so in LA Times.
