The Kauai Joint Fact Finding Group's
draft report on pesticide use — set for release on Sunday — has
been delayed until Jan. 6.
Why? Because “Councilmember JoAnn
Yukimura has requested we change the
public comment period in light of the holidays,” wrote JFFG
Facilitator Peter Adler in Update #7.
It's unclear why JoAnn should have any
say in the group's proceedings. What's more, her meddling actually
works against the public interest. Now folks will have just five days
— rather than 22 — to read and digest the document before the
JFFG holds a public briefing on it Jan. 11.
Initially, the draft report was due to
be posted on line Dec. 20, with public comments taken through Jan.
13. Now it's set for release on Jan. 6, with the public comment
period ending Jan. 31. In any case, the briefing remains scheduled
for Jan. 11, giving folks precious little time to prepare.
Regardless of the report's timing, it
appears the JFFG has found no smoking gun, uncovered no evidence to
support the oft-uttered claims that the seed companies are sickening
folks on Kauai.
But that hasn't stopped certain
interested parties — namely Councilman Gary Hooser — from trying
to dredge something up. Last month, he began pressing the county
water department to test Kauai's drinking water for the pesticide
chlorpyrifos.
Why,
you might ask, did Hooser only now make such a request, when it's
been known for years that the seed companies apply it? (Golf courses
and pest control companies use it, too.) Indeed, Hooser and other
anti-GMO activists have fingered chlorpyrifos as the source of
numerous human health woes. But they never requested testing until the JFFG, which will also address “Recent Pesticide Developments” concerning
glyphosate and chlorpyrifos, is on the eve of releasing its report.
Studies
have linked chlorpyrifos to neurological and other development
problems, especially when there's prenatal exposure. But the key here
is exposure. Hooser and the anti-GMO activists have
consistently claimed that westsiders are being harmed by pesticide
drift when chlorpyrifos is applied to the fields. This contention has
underscored their demands for both disclosure and buffer zones.
Meanwhile, in the real world of science, the EPA has been conducting a review of chlorpyrifos for the past
several years. Its studies have effectively undermined the
contention that Kauai folks are even being exposed to airborne
chlorpyrifos, much less harmed by it. To wit:
To
increase protection for children and other bystanders, chlorpyrifos
technical registrants voluntarily agreed to lower application rates
and to other spray drift mitigation measures. The resulting buffer distances (feet) necessary to
reach the level of concern for adults (females 13-49 years old) and
children (1 to < 2 years old) with use of certain application
rates, nozzle droplet types, and application methods range from 0 to
25 feet.The estimated buffer distances are less than those agreed to by the technical registrants in July 2012.
Furthermore,
emphasis added:
In
January 2013, a preliminary assessment of the potential risks from
chlorpyrifos volatilization was
conducted. However,
this assessment was revised in June 2014
following submission of two
vapor phase inhalation toxicity studies which indicate no adverse
effects occurred even at the
saturation concentration for chlorpyrifos and chlorpyrifos oxon.
Because these new studies demonstrated
that no toxicity occurred even at the saturation concentration, which
is the highest physically
achievable concentration, there are no anticipated risks of concern
from exposure to the
volatilization of either chlorpyrifos or chlorpyrifos oxon.
It
appears, then, that Kauai people are not at risk from either
chlorpyrifos drift or volatilization, as has been widely claimed by
Hooser and the anti-GMO activists. And with the seed companies
voluntarily agreeing to 100-foot buffers, any risk is even further
minimized.
So
if you're trying to make chlorpyrifos the bad guy, the source of so
many health woes among westsiders, you've got to try and find another
source of exposure, with food and water the only possible culprits.
The
EPA report notes:
Though there do not appear to be any risks
from exposure to chlorpyrifos from food, when that exposure is
combined with estimated exposure from drinking water in certain
watersheds, EPA cannot conclude that the risk from the potential
aggregate exposure meets the FFDCA safety standard.
There may be potential risks for people whose drinking water comes from small water systems in heavily farmed areas where chlorpyrifos may be widely used.
Hence,
Hooser's request for water testing. Because he's concluded that west Kauai
is one of those “vulnerable watersheds."
Is it? Well, according to data from the Good Neighbor program, the seed companies applied chlorpyrifos to about 1500 acres over the past two years. That's less than a tenth of the land they lease
and a fraction of the overall westside acreage. Is that an intensive
use in a small watershed? The state and county apparently don't think
so.
On
Nov. 2, Hooser sent a memo to Kirk Saiki, manager and chief
engineering of the county Department of Water (DOW). Gary wanted to
know if DOW is testing for chlorpyrifos in the county's drinking
water. If so, had detectable levels been found, and where? And if
not, why not?
Kirk
replied that the EPA “has set a guideline for chlorpyrifos in
drinking water at 2 ug/l (micrograms per liter or parts per billion),
but has not set a drinking water standard likely due to the fact that
chlorpyrifos exhibits a low solubility in water.”
DOW
does not test for chlorpyrifos, Kirk said, but it did consult with
the state Department of Health (DOH) “to determine if there was a
concern about chlorpyrifos contamination of the groundwater on
Kauai.”
The DOH
noted that the largest user of chlorpyrifos is corn, and the
organophosphate is applied to the plant, not the ground, so it has
more potential to drift than fall to the ground. What's more, it has
a short half-life of 51 days. Additionally, a model developed by DOH
and the University of Hawaii to predict the leaching potential of
chlorpyrifos “shows the chance of groundwater contamination by chlorpyrifos on Kauai to be unlikely.”
Even
the EPA is not especially concerned about groundwater. It
specifically notes, “exposure
to chlorpyrifos-oxon in drinking water derived from surface
water may pose an
exposure concern.” Kauai drinking water is primarily derived from
groundwater sources, except in parts of Lihue.
So why
not just go ahead and test? Well, testing costs money, and the water
department already tests for dozens of compounds, including atrazine
and glyphosate, that it believes are more likely than chlorpyrifos to find their way into water
supplies.
In
today's The Garden Island, Hooser is quoted as saying, in opposition
to a half-percent increase in the general excise tax:
“Experience has taught me that we
never have enough money to do what we need to do. I’m looking for
other funding options.”
If Hooser sincerely believes the public
is at risk from chlorpyrifos, and the
county and state are derelict for not testing, perhaps he could convince one of his
wealthy donors to pick up the tab. Or maybe HAPA and
Center for Food Safety could have paid for some actual tests, rather
than send people on a propaganda mission to Switzerland or bring in
Vandana Shiva for yet another talk.
But then, why would they waste their
own dough on a wild goose chase when they can try to bully public agencies into footing the bill?
