Over one hundred years
ago, scientist and inventor Nikola Tesla stood on the land in Shoreham that
he called Wardenclyffe, and imagined a tower that would rise over 180 feet
above the landscape. Eventually, with funding from financier J.P.
Morgan, Tesla began the work of building that tower, which he intended to
use for communication and for transmission of electromagnetic waves. The
tower was never totally completed, but some of the base on which it stood
still remains, as does the laboratory where Tesla worked, a building
designed by Tesla’s friend, noted architect Stanford White. That was
in 1902. Now, in 2006, the property is owned by Agfa Corporation, which
purchased the property form Peerless Photo Products. Peerless, and later,
Agfa, processed photographic materials at the site. In that process,
chemicals including cadmium were thrown away in catch basins and in the base
of what was the tower. The base of the tower was composed in part, of a
large hole in the ground that extended about 120 feet deep. This tower base
became a convenient site for the disposal of chemicals and other items,
too. For over a decade, under the direction of the New York Department
of Environmental Conservation, Agfa has been engaged in planning a cleanup
of the site, in which contaminated soils are removed, clean fill is trucked
in, and the tower base is capped to prevent leaching of potentially hazardous materials
into the groundwater. That process is nearing completion, and the soil
removal and replacement at several locations on the site have been accomplished.
The tower base,
however, has presented some unique challenges. Agfa and the DEC have been
sensitive to the preservation of the tower base foundation and walls,
considering that future technology may provide a way to excavate the base in
a safe way, while maintaining the archeological and scientific integrity of
the base. In the process of sealing and capping the contaminated areas of
the base soils, large chunks of concrete have been encountered, preventing
some of the original plan of sealing and capping from being implemented. As
a result, Agfa and the DEC have been exploring alternatives.
“We had a slight
delay due to technical problems with the tower base. It wasn't constructed
as we envisioned,” said Charlene Graff, Agfa’s engineer in charge of the
project.
The excavation of
the tower base is wider than Agfa originally intended, shaped similarly to a
funnel: wider at the top than at the base.
"We found significant debris and concrete.
Some of the pieces were over one foot thick and eight feet long. It appears
to be quite old, and doesn’t have any rebar or reinforcement, so we are
unsure about where it came from. It might have sloughed off the tower
base,” she said.
"We've requested the
state to allow us to use a different technology to deliver the
stabilizer,” said Graff. “Originally we intended to use an augur technique.
Now we’d like to use jet-grouting equipment. It allows us to deliver the
stabilizing solution. A much smaller probe goes down, with much greater
success. Instead of a mixing or paddling motion it uses an injection method.”
“They looked
around and found out there is another method to deliver the cement mixture
[stabilizer] that is a new delivery method,” said Girish Desai, DEC
director of the project.
"We want to do it
right,” said Desai. He also said the excavation of the tower base is about
55 feet across and 28 feet deep.
Once approval is given for the change in
delivery method for the stabilizer, it will take several weeks for the
equipment to arrive.
"A few months ago we
were ahead of schedule. Then the problems with the concrete in the tower
base were discovered. Now it will take longer than we planned,” said Graff.
According to Graff,
most of the rest of the excavation is completed, except for the portion to
be done on LIPA’s right-of-way and some soil replacement on other
sections. She said the last parts will be completed as weather permits, with
soil replacement and seeding perhaps possible in April. Asked about the air
quality monitoring that was done during the earlier soil removal, Graff said
there were no problems.
"The air readings
showed no levels of anything were raised,” she said. The future of the
land, when the cleanup is complete, is uncertain. Agfa and Brookhaven Town
have discussed a potential donation of the land to the Town. Discussion has
also been held between Brookhaven Town and Friends of Science East, Inc., a
local group that would like to establish a science museum and Tesla archive
in the old laboratory when the work is completed. The Tesla Science Center
at Wardenclyffe would house memorabilia of Tesla and his work, and offer
programs and exhibits for students and the general public on science-related
topics, along with community space for meetings and other activities. The
Shoreham Hamlet Study includes the concept of a science museum at the site,
and there has been general support in the community for that possibility.
