Penn State Hosts
Waste Water Meet
Participants in a Penn State
conference on waste water
renovation were urged this
morning by Maurice K. Goddard,
Secretary of the Pennsylvania
Department of Environmental
Resources, to become
evangelists for “the ultimate
recycling idea.”
“Yous should be able, after this
conference, to go home and
convince politicians, en
vironmentalists, ecologically
minded citizens, and everyone
else, that land disposal of waste
water is worthy of their support,”
he said.
The Secretary opened a four
day symposium on Tuesday
celebrating the tenth anniversary
of a Penn State experiment
demonstrating that waste water,
scientifically sprayed over crop
and forest land, can be made fit
to drink.
Registraton at the conference
surprised even its organizers.
Three hundred were expected;
almost four hundred turned up.
Conference co-director. Dr.
William Sopper, reported that
“we were literally inundated with
last-minute requests for
registration, most of which had to
be refused.”
Those attending, said Sopper,
included not only university
researchers but local govern
ment officials, water authority
members, public health and
regulatory agency personnel, and
representatives of private con
sulting firms.
“The heavy turnout,” he said,
“only confirms what Federal
officials have been telling us:
there is an unprecedented up
swelling of interest in land
disposal of effluent. Were space

SAFE
STORAGE!
The Butler trademark
tells you so
Butler quality grain bins give
you the safest, most dependable
•torage you can buy. They’re
pre-engineered that way by the
men who know grain storage
best. What’s more, it’s easy to
convert a Butler bin into an on
farm drying system, if you de
cide to dry your own grain. Let
us discuss your grain storage
needs with you. Just give u*

available, we could easily have
doubled the attendance at this
symposium.”
The ultimate recycling idea,
known in its Penn State version
as “The Living Filter,” involves
allowing effluent to percolate
through the soil; microorganisms
there ingest some of the im
purities and crops and trees take
up the rest as nutrients. Thus,
total biodegradability is
achieved.
A spin-off project, now in its
third year, has shown that the
same technique can provide, in
one growing season, what one
project scientist describes as
“lush ground cover” on the worst
soil in the world: strip mine soil.
And spray irrigation, Secretary
Goddard said in his talk, “has a
potential for dramatically im
proving the quality of our
nation’s waterways . . . Treating
waste products so they are
LET THE SUNSHINE IN WITH...
SOLAIR SYSTEMS
WE'RE INTERESTED IN ECOLOGY!
With our completely covered lots and a sun roof
with an open peak, ram water does not enter the bay
area and maximum evaporation of animal liquids is
obtained An “all-drained” floor system is installed
and a curbed fence line keeps manure in place to be
scraped into a liquid pit or a push-off loading system
By preventing manure run-off the surrounding area is
not polluted.
Yes, since your urban neighbors and government
fathers are interested m ecology, we are ready to help
you build a system that will put you ahead on the
pollution problem
And, low moisture levels in Solair Systems results in
less bacteria action and fewer odors.

somewhat improved and then
discharging them into our
waterways does not meet the
goals of ecological scienCe . . .
“Hence the interest of many
ecologists in using waste water to
reclaim and fertilize land and,
using land as a filter ... a living
filter, if you like ... to purify the
water.”
Daily tours of the project site
are included in the conference
agenda, as is the premiere of a
documentary film on the subject.
Inquiries about the project,
operated under the Institute for
Research on Land and Water
Resources, have come from all
fifty states, all the provinces of
Canada, and dozens of foreign
countries, some as far away as
Thailand.
At the current symposium 45
states were represented, as well
as Puerto Rico, the Virgin
Islands, and five provinces in
Canada.
In addition, there was one
registrant from New Zealand.
Accidents involving the feet
and toes account for about one
out of every ten disabling work
injuries. When it comes to per
sonal protective equipment on
the ranch or farm, one of the least
dispensable items is the safety
shoe.
