Avanyu,
the Native American plumed-serpent deity, guardian of springs and
watercourses.
Avanyu
is a figure in Native American rock
art "petroglyphs",
paintings,
and ancient
and contemporary
pottery. This beautiful version of Avanyu was created by my
employer,
the New Mexico Environment
Department,
and aptly adorns various water-quality protection documents. I
worked in the Ground
Water Quality Bureau for nearly 25
years, and then took a promotion into the Field Operations Division, to
lead the Liquid
Waste Program. We issue permits for waste discharges,
respond to chemical
spills, investigate ground-water
pollution, and oversee cleanups performed by the responsible
persons.
We also perform regional surveillance, and special studies like testing
for pharmaceutical
residues in ambient water.
My work web
page has some fabulous links to
lots of free information, pictures,
images, maps, reports, chemical data bases, and environmental web sites
for kids. Protecting
ground
water from contamination
has long been my specialty, but my expertise is not limited to the
subsurface.
Endocrine-disrupting chemicals (EDC's) will soon be identified as the
greatest
health-threat from our ambient environment. I presented a paper
at
the 2nd
International Conference on Pharmaceuticals and Endocrine Disrupting
Chemicals
in Water, October 9-11, 2001 in
Minneapolis.
Electromagnetic
Induction "Terrain Conductivity" Geophysical Survey. Here
we are preparing to run a geophysical survey. This method
involves
inducing electrical currents in the Earth and measuring their magnetic
fields. The greater the field, the greater the current.
Certain
types of ground-water pollution conduct electricity better than
uncontaminated
ground water, so we use this geophysical method to prospect for and map
plumes of ground-water pollution.
Drilling
a Test Hole. Here I
am drilling a test boring at a
site
where chemicals had been illegally dumped. Our investigation
determined
that both soil and ground water were contaminated with chlorinated
solvents.
Both the company, and its owner, were convicted of criminal violations
of the New Mexico Water Quality Act after a jury trial.
Encapsulation
Suit. Inside this
plastic "space suit" you breathe
from
a tank of supplied air that creates a positive pressure inside the suit
to keep out nasty chemicals. This is Level A, the maximum,
personal
protection.
Bailing
a sample from a monitoring well. Water from this well
was so contaminated that I had to wear a protective suit and breathe
through
an air-purifying respirator. This is Level C personal
protection.
The well was contaminated with gasoline and solvents from an illegal
landfill.
Sampling
a waste lagoon. I
used a dipper to collect a sample
while
my field partner monitored the air for toxic vapor. We both wore
chemical-resistant plastic booties so our field boots would not get
contaminated.
This was a dump site used by "honey wagon" (vacuum truck)
operators.
They were only supposed to haul septage, the material periodically
pumped
out of septic tanks but, as our sampling determined, chemical wastes
also
were being dumped here.
Sampling
an abandoned tanker. This
tanker trailer was filled
with
PCB-laden waste oil, and abandoned on a county road in a
residential/industial
area. I dipped a glass rod inside the tanker and put my thumb on
the top opening to collect the sample. The situation was resolved
with an emergency Superfund removal action. The oil was pumped
out
into 55 gallon drums. The tanker was cut in half and taken to a
hazardous
waste disposal site along with the drums of oil. We were never
able
to identify the perpetrator of this environmental crime.
