‘Green’ paving helps the bay, human health

Michael Kiparsky and Max Gomberg write for San Francisco Chronicle, November 12, 2013

Every time it rains, San Francisco Bay gets a little sicker. But it doesn’t have to be that way. Asphalt streets collect pollutants from motor oil to metals from brake pads to nutrients from garden fertilizers. Rains quickly wash it all into storm drains, local streams and the bay. When combined with decades of industrial pollution, storm-water runoff damages marine life and kills fish, leaving those that survive too toxic to eat. We cannot completely repair the bay’s ecology, but we can improve its health and ours by changing the way we build city streets.

All fracked up: mixing oil and water rattles the Golden State

Michael Kiparsky quoted and Jayni Hein cited in California Lawyer, November, 2013

Kiparsky says there would have to be a huge increase in fracking before it registers as a significant part of the state’s overall water use. “That said, all water is local,” he adds. “The impacts on local water sources could be an issue. We just don’t know at this point.”

A recent article he coauthored with Berkeley Law colleague Jayni Foley Hein states: “Fracturing ‘flowback’ … and ‘produced water’ (all waste-water that emerges from the well after production begins) contain potentially harmful chemicals, some of which are known carcinogens. Produced water is also highly saline and potentially harmful to humans, aquatic life, and ecosystems.”

Could fracking the Monterey Shale lead to the next Big One?

Michael Kiparsky quoted in The Bay Nature Institute, September 17, 2013

“When a hole is drilled, it creates a conduit through which oil, gas, and fracking fluids could move upwards,” Kiparsky says. “If there was a casing failure, that movement into the bottom of the aquifer could happen within hours or days, but wouldn’t necessarily be expressed at the surface, or be visible, for decades or centuries.”… Kiparsky warns of the risks of irreversible contamination of surface and groundwater near wells, unless the method is carefully monitored and controlled.

Can we save our urban water systems?

Michael Kiparsky article cited in TerraDaily, September 9, 2013

The article, entitled “The Innovation Deficit in Urban Water,” contends that for new innovations to be implemented successfully, engineers must understand the social, economic, institutional, and political mechanisms that underlie the human-technology interface.

Fracking is under dispute in California

Michael Kiparsky quoted in Neue Zürcher Zeitung, July 30, 2013

Kiparsky is particularly worried over what is still to come in California. “Since we don’t yet understand the existing risks, we certainly don’t understand the risks of technologies that have not yet been used.”

Fracking in California’s oil frontier

Michael Kiparsky quoted in The Sacramento Bee, July 7, 2013

“There is tremendous (scientific) uncertainty,” said Michael Kiparsky … co-author of a recent report that found gaping holes in California’s regulation of fracking. “California has historically been a leader in the governance of environmental issues” –but not fracking, Kiparsky said. “There is the opportunity to learn from other states … and try not to repeat their learning experiences.”

Assembly fracking hearing looks at impacts to water quality

Jayni Foley Hein, Michael Kiparsky quoted in Association of California Water Agencies, May 14, 2013

“Once fracking has been conducted, its effects may be impossible to reverse,” Kiparsky said, adding that “the science remains uncertain, particularly in the face of technology that is rapidly evolving.”

Jayni Foley Hein … added that the regulations put forward in DOGGR’s discussion draft are currently not as robust as those found in other states. She said improvements are needed to the public notice process pertaining to fracking operations, as well as disclosure about “trade-secret” fracking chemicals.

Fracking in state needs close oversight

Jayni Foley Hein, Michael Kiparsky write for San Francisco Chronicle, May 12, 2013 (registration required)

New fracturing techniques combined with demand for oil have led to alarming projections of dramatically increased fracking activity in California. Such developments may have outstripped the ability of responsible government agencies to effectively oversee fracking activity and its attendant impacts on our land, air and water resources.
