California Halts Injection of Fracking Waste, Warning it May Be
Contaminating Aquifers
State’s drought has forced farmers to rely on groundwater, even as
California aquifers have been intentionally polluted due to exemptions for
oil industry.

California officials have ordered an emergency shut-down of 11 oil and gas
waste injection sites and a review more than 100 others in the state's
drought-wracked Central Valley out of fear that companies may have been
pumping fracking fluids and other toxic waste into drinking water aquifers
there.
The state's Division of Oil and Gas and Geothermal Resources on July 7
issued cease and desist orders to seven energy companies warning that they
may be injecting their waste into aquifers that could be a source of
drinking water, and stating that their waste disposal "poses danger to
life, health, property, and natural resources." The orders were first
reported by the Bakersfield Californian, and the state has confirmed with
ProPublica that its investigation is expanding to look at additional wells.
The action comes as California's agriculture industry copes with a drought
crisis that has emptied reservoirs and cost the state $2.2 billion this
year alone. The lack of water has forced farmers across the state to
supplement their water supply from underground aquifers, according to a
study released this week by the University of California Davis.
The problem is that at least 100 of the state's aquifers were presumed to
be useless for drinking and farming because the water was either of poor
quality, or too deep underground to easily access. Years ago, the state
exempted them from environmental protection and allowed the oil and gas
industry to intentionally pollute them. But not all aquifers are exempted,
and the system amounts to a patchwork of protected and unprotected water
resources deep underground. Now, according to the cease and desist orders
issued by the state, it appears that at least seven injection wells are
likely pumping waste into fresh water aquifers protected by the law, and
not other aquifers sacrificed by the state long ago.
"The aquifers in question with respect to the orders that have been issued
are not exempt," said Ed Wilson, a spokesperson for the California
Department of Conservation in an email.
A 2012 ProPublica investigation of more than 700,000 injection wells across
the country found that wells were often poorly regulated and experienced
high rates of failure, outcomes that were likely polluting underground
water supplies that are supposed to be protected by federal law. That
investigation also disclosed a little-known program overseen by the U.S.
Environmental Protection Agency that exempted more than 1,000 other
drinking water aquifers from any sort of pollution protection at all, many
of them in California.
Those are the aquifers at issue today. The exempted aquifers, according to
documents the state filed with the U.S. EPA in 1981 and obtained by
ProPublica, were poorly defined and ambiguously outlined. They were often
identified by hand-drawn lines on a map, making it difficult to know today
exactly which bodies of water were supposed to be protected, and by which
aspects of the governing laws. Those exemptions and documents were signed
by California Gov. Jerry Brown, who also was governor in 1981.
State officials emphasized to ProPublica that they will now order water
testing and monitoring at the injection well sites in question. To date,
they said, they have not yet found any of the more regulated aquifers to
have been contaminated.
"We do not have any direct evidence any drinking water has been affected,"
wrote Steve Bohlen, the state oil and gas supervisor, in a statement to
ProPublica.
Bohlen said his office was acting "out of an abundance of caution," and a
spokesperson said that the state became aware of the problems through a
review of facilities it was conducting according to California's fracking
law passed late last year, which required the state to study fracking
impacts and adopt regulations to address its risks, presumably including
underground disposal.
California officials have long been under fire for their injection well
practices, a waste disposal program that the state runs according to
federal law and under a sort of license — called "primacy" — given to it by
the EPA.
For one, experts say that aquifers the states and the EPA once thought
would never be needed may soon become important sources of water as the
climate changes and technology reduces the cost of pumping it from deep
underground and treating it for consumption. Indeed, towns in Wyoming and
Texas — two states also suffering long-term droughts — are pumping,
treating, then delivering drinking water to taps from aquifers which would
be considered unusable under California state regulations governing the oil
and gas industry.
In June 2011, the EPA conducted a review of other aspects of California's
injection well program and found enforcement, testing and oversight
problems so significant that the agency demanded California improve its
regulations and warned that the state's authority could be revoked.
Among the issues, California and the federal government disagree about what
type of water is worth protecting in the first place, with California law
only protecting a fraction of the waters that the federal Safe Drinking
Water Act requires.
The EPA's report, commissioned from outside consultants, also said that
California regulators routinely failed to adequately examine the geology
around an injection well to ensure that fluids pumped into it would not
leak underground and contaminate drinking water aquifers. The report found
that state inspectors often allowed injection at pressures that exceeded
the capabilities of the wells and thus risked cracking the surrounding rock
and spreading contaminants. Several accidents in recent years in California
involved injected waste or injected steam leaking back out of abandoned
wells, or blowing out of the ground and creating sinkholes, including one
2011 incident that killed an oil worker.
The exemptions and other failings, said Damon Nagami, a senior attorney
with the Natural Resources Defense Council in an email, are "especially
disturbing" in a state that has been keenly aware of severe water
constraints for more than a century and is now suffering from a crippling
drought. "Our drinking water sources must be protected and preserved for
the precious resources they are, not sacrificed as a garbage dump for the
oil and gas industry."
Still, three years after the EPA's report, California has not yet completed
its review of its underground injection program, according to state
officials. The scrutiny of the wells surrounding Bakersfield may be the
start.
