Lee County is once again looking for the
chemical arsenic on Pine Island. That’s after documents surfaced from a few
years ago showing arsenic levels hundreds and sometimes thousands of times
higher than the federal government allows on private and public lands.
say this could’ve potentially harmed island residents and wildlife within the
surrounding estuaries. Arsenic is a naturally occurring
metal, but state and federal health officials say if high levels are consumed,
it can make people sick and cause cancer.
records show state environmental officials knew about the high arsenic levels
but decided to stop testing for it in 2015.

found out dangerously high levels of the chemical arsenic were recorded on land
in his neighborhood dating back to at least 2011.
higher levels of arsenic were detected on county-owned conservation land a

it means? I’m not sure," said Deile.
Local hydrogeologist Greg Rawl brought this
information to light.
first saw the levels, my first thought was ‘well, there's an error here,’”
said he later confirmed with county officials there was no error. Rawl is on
2020 Committee that
oversees the county’s purchasing and monitoring of preserved lands. During a
committee meeting, he said he was surprised to find the Pine Island Wastewater
Treatment Plant sprays its liquid waste onto the preserve, and in Bill Deile’s

elevated levels of nitrogen and phosphorus,” said Rawl.

permit requires the county to test the groundwater through monitoring wells to
make sure the spraying is not negatively affecting the land. So Rawl pulled up
past reports Lee Utilities sent to the Florida Department of Environmental Protection
from a DEP database. WGCU also acquired documents the DEP said it did not have.
But the county had copies with a DEP date stamp on them.
“So when I
started looking at the data, I was kinda blown away,” said Rawl.
documents WGCU obtained show the highest level of arsenic reported by Lee
County to the state was in 2013-- that number was 14,000 times higher than the
U.S. Environmental Protection Agency allows in drinking water. And nearly 3,000
times higher than EPA standards for surface water bodies.
and DEP standards for drinking water do not allow arsenic to surpass 10
micrograms per liter, and their standards do not allow surface water bodies to
go over 50 micrograms per liter. But Lee County reported to the DEP that the
conservation land had the highest arsenic level at 141,000 micrograms per liter
in 2013. And in 2012, the Island Acres Estate community well showed the highest
arsenic level surpassing 4,000 micrograms per liter.
Dr. Ronald Gots is a private toxicologist
in Martin County. He said these elevated levels of arsenic could harm people if
they drank the arsenic-laden groundwater, or handled contaminated soil.
not an amount that you would like to have in your drinking water because if you
drank a liter a day of that, that could make you sick,” said Gots.
declined to do a recorded interview for this story, but a county spokesperson
said in an email that Pine Island residents do not use groundwater wells for
drinking. Even so, Doctor Gots said the soil in Bill Deile’s neighborhood should, at least, be tested.
Hydrogeologist Greg Rawl said there are a
lot of unanswered questions about how this arsenic got onto the land. But he
said the first thing that comes to his mind is…
dumping. We have absolutely no proof of that, but to get these high levels,
chances are would have to be some kind of waste product from some industrial
use,” said Rawl.
Public documents show the county hired
outside consultant Daniel Acquaviva sometime in 2014 to recommend what to do
about the arsenic problem. His report blamed “cattle grazing operations” for
the spikes in arsenic. Rawl said there are a few things wrong with this theory.
said cattle do not generate arsenic. Cattle dipping sites do. They’re
essentially holes in the ground filled with arsenic to dip the cattle and
remove ticks. But the DEP’s website reports the only cattle dipping site
somewhere on Pine Island was in 1933.
Two: Cattle have been grazing on Pine
Island Flatwoods Preserve since the early 2000's, so Rawl questions why arsenic
levels would spike up all of a sudden in 2011. And three: Rawl said cattle
grazing on the preserve does not explain why high levels of arsenic would also
be detected at the Island Acres Estate neighborhood two miles away.
2020 manager Cathy Olson backed up Rawl’s skepticism of cattle causing the high
arsenic at a public committee meeting in March.
really know where it came from... we just don’t know,” said Olson.
said there’s something else wrong with consultant Daniel Acquaviva’s report.
Rawl said his calculations are not right.
consultant used the numbers that I pulled offline with the one interesting
exception… it didn't correspond to what the county had been submitting to the
DEP for years,” Rawl said.
the numbers Acquaviva used would have been right if he multiplied them by one
thousand. Acquaviva did not return WGCU’s calls for comment.
Acquaviva's final report recommends the
wells be closed. Then, based on his report, the DEP allowed Lee County to close
those wells and open up new ones in 2015. Also, the DEP removed arsenic from
the list of things to test for in the new wells.
declined to do a recorded interview, but in an email a spokesperson says the
agency closed the wells and stopped testing for arsenic because it determined
the chemical was not coming from the reuse spray water at the Pine Island
Wastewater Treatment Plant. The spokesperson would not answer a question
regarding whether the DEP was concerned about the environment or nearby
after hydrogeologist Greg Rawl presented his concerns, the Conservation 2020
committee hired a company to open up three new wells near the previous ones on
the Pine Island Flatwoods Preserve and started testing again for arsenic in
“So from a
2020 perspective, we've done what we're supposed to do, I think," said
Rawl. "And ethically, I’ve informed the folks that appointed me to this
position of the problems, so I’ve done what I can do.”
first and latest report shows arsenic is present at only three times higher
than federal drinking water standards—a significant difference from being
thousands of times over in the recent past. So the committee decided not to
attempt arsenic removal since they say it poses no threat to the people or the
environment at this time.
But the Florida Department of Health’s
website says “arsenic deposited on the ground from industrial or agricultural
uses tends to stay in the top few feet of soil for a long time.” So that brings up a whole other
question for Rawl: Where did the arsenic go?
“That kind of a rapid
decrease would indicate that these really high levels of arsenic flushed out
into the tidal waters very quickly,” said Rawl. “And based upon my
knowledge of the area, groundwater doesn’t move that quickly.”
He said another
possibility is something was done differently in the testing of these new wells
than what was done in the past. The Conservation 2020 committee has a contract
with the company Benchmark
Enviroanalytical, Inc. to
test quarterly for the next two years at a total cost of more than $30,000.
Back on Pine Island
near Bill Deile’s lake, he said he wants to stay on top of the results going
“I think the
government has this duty to make people aware of things,” said Deile.
“People by and large that live out here are very ecologically-oriented. There’s
a lot of industry that depends on that, such as fishing. And people are very
aware of the quality of the water, mostly the water in the Pine Island
Sound and its estuaries, and the microcosm it has for birth and rebirth of the
marine species that live there.”
After this investigation aired
and was published, WGCU's call-in talk show Gulf
Coast Live hosted a conversation to breakdown the story the same week.
And the show's producers invited the DEP and Lee County to speak on the
program. Both declined to appear on GCL, but county spokesman Timothy
Engstrom emailed a response saying the numbers Lee Utilities reported to the
DEP for years may have been wrong.
of the data given to DEP by Lee County Utilities in past years may have been
filed in the incorrect unit of measurement," said Engstrom. "Lee
County is in the process of resubmitting the data collected to the DEP. It is
possible some results may have been reported incorrectly higher than they
initial reporting of high arsenic on Pine Island, neither Lee County nor the
DEP ever indicated to us that these quarterly reports could be wrong. And if
the county had been wrongly reporting arsenic levels at thousands of times
higher than is allowed by the state and federal government, that brings up yet
another question: Why are Lee County and the DEP just now addressing the
issue from years past?
spokesperson Dee Ann Miller said in an emailed response to GCL producers that
the agency is waiting for the revised Lee Utilities numbers. Miller also
said that the monitoring well on Pine Island Flatwoods Preserve was no longer a
good source for testing, which led to the well's closure in 2015.
we saw elevated levels of other constituents for this well, such as fecal
coliform, this also indicated a loss of integrity of the well itself," said
