"Mistakes were made". A state that is running out of water rapidly is still fracking: not only that, but is injecting toxic waste water into its drinking water. Insane!
Waste Water from Oil Fracking Injected into Clean Aquifers
Waste Water from Oil Fracking Injected into Clean Aquifers
State
officials allowed oil and gas companies to pump nearly three billion
gallons of waste water into underground aquifers that could have been
used for drinking water or irrigation.

Those
aquifers are supposed to be off-limits to that kind of activity,
protected by the EPA.
“It’s
inexcusable,” said Hollin Kretzmann, at the Center
for Biological Diversity in
San Francisco. “At (a) time when California is experiencing one of
the worst droughts in history, we’re allowing oil companies to
contaminate what could otherwise be very useful ground water
resources for irrigation and for drinking. It’s possible these
aquifers are now contaminated irreparably.”
California’s
Department of Conservation’s Chief Deputy Director, Jason Marshall,
told NBC Bay Area, “In multiple different places of the permitting
process an error could have been made.”
“There
have been past issues where permits were issued to operators that
they shouldn’t be injecting into those zones and so we’re fixing
that,” Marshall added.
In
“fracking” or hydraulic fracturing operations, oil and gas
companies use massive amounts of water to force the release of
underground fossil fuels. The practice produces large amounts of
waste water that must then be disposed of.
Marshall
said that often times, oil and gas companies simply re-inject that
waste water back deep underground where the oil extraction took
place. But other times, Marshall said, the waste water is re-injected
into aquifers closer to the surface. Those injections are supposed to
go into aquifers that the EPA calls “exempt”—in other words,
not clean enough for humans to drink or use.
But
in the State’s
letter to the EPA,
officials admit that in at least nine waste water injection wells,
the waste water was injected into “non-exempt” or clean aquifers
containing high quality water.
For
the EPA, “non-exempt” aquifers are underground bodies of water
that are “containing high quality water” that can be used by
humans to drink, water animals or irrigate crops.
If
the waste water re-injection well “went into a non-exempt aquifer.
It should not have been permitted,” said Marshall.
The
department ended up shutting down 11 wells: the nine that were known
to be injecting into non-exempt aquifers, and another two in an
abundance of caution.
In
its reply
letter to the EPA,
California’s Water Resources Control Board said its “staff
identified 108 water supply wells located within a one-mile radius of
seven…injection wells” and that The Central Valley Water Board
conducted sampling of “eight water supply wells in the vicinity of
some of these… wells.”
“This
is something that is going to slowly contaminate everything we know
around here,” said fourth- generation Kern County almond grower Tom
Frantz, who lives down the road from several of the injection wells
in question.
According
to state records, as many as 40 water supply wells, including
domestic drinking wells, are located within one mile of a single well
that’s been injecting into non-exempt aquifers.
That well is
located in an area with several homes nearby, right in the middle of
a citrus grove southeast of Bakersfield.
State
records show waste water from several sources, including from the oil
and gas industry, has gone into the aquifer below where 60 different
water supply wells are located within a one mile radius.
“That’s
a huge concern and communities who rely on water supply wells near
these injection wells have a lot of reason to be concerned that
they’re finding high levels of arsenic and thallium and other
chemicals nearby where these injection wells have been allowed to
operate,” said Kretzmann.
“It
is a clear worry,” said Juan Flores, a Kern County community
organizer for the Center on Race, Poverty and The Environment. “We’re
in a drought. The worst drought we’ve seen in decades. Probably the
worst in the history of agriculture in California.”
“No
one from this community will drink from the water from out of their
well,” said Flores. “The people are worried. They’re scared.”
The
trade association that represents many of California’s oil and gas
companies says the water-injection is a “paperwork issue.” In a
statement issued to NBC Bay Area, Western States Petroleum
Association spokesman Tupper Hull said “there has never been a bona
vide claim or evidence presented that the paperwork confusion
resulted in any contamination of drinking supplies near the disputed
injection wells.”
However,
state officials tested 8 water supply wells within a one-mile radius
of some of those wells.
Four
water samples came back with higher than allowable levels of nitrate,
arsenic, and thallium.
Those
same chemicals are used by the oil and gas industry in the hydraulic
fracturing process and can be found in oil recovery waste-water.
“We
are still comparing the testing of what was the injection water to
what is the tested water that came out of these wells to find out if
they were background levels or whether that’s the result of oil and
gas operation, but so far it’s looking like it’s background,”
said James Marshall from the California Department of Conservation.
Marshall
acknowledged that those chemicals could have come from oil
extraction, and not necessarily wastewater disposal.
“But
when those (further) test results come back, we’ll know for sure,”
Marshall said.
When
asked how this could happen in the first place, Marshall said that
the long history of these wells makes it difficult to know exactly
what the thinking was.
“When
you’re talking about wells that were permitted in 1985 to 1992,
we’ve tried to go back and talk to some of the permitting
engineers,” said Marshall. “And it’s unfortunate but in some
cases they (the permitting engineers) are deceased.”
Kern
County’s Water Board referred the Investigative Unit to the state
for comment.
California
State officials assured the EPA in its letter that the owners of the
wells where chemicals were found have been warned and could ask for
further testing of their drinking wells.
