The U.S. Environmental Protec
tion Agency has awarded $80,000 to
a Texas Agricultural Experiment
Station scientist for the first year of a
three-year study which will be ad
ministered by the A&M Research
Foundation on a problem associated
with the growing urban sprawl.
Research investigations will de
termine the accumulation and pas
sage of pollutants in domestic septic
tank disposal fields, and evaluate
the movement of such pollutants
through the subsurface environ
ment from disposal fields.
Project Leader for the investiga
tion is Dr. Kirk W. Brown, TAES
assistant professor of soil physics.
Assisting him is Dr. Calvin Woods,
Texas Engineering Extension Ser
vice, professor of civil engineering
at A&M.
“As the urban sprawl continues to
take in more and more land in Texas
and across the nation, the problem
of pollutants from domestic septic
tank disposal fields has become a
major concern. Surveys indicate
that at this time 25-30 percent of
domestic sewage in the U.S. is dis
posed of in septic tank-septic field
systems. Definitive studies are
needed to determine the accumula
tion, movement and degradation of
potential ground-water pollutants
from the disposal fields,” em
phasizes Brown.
Agricultural scientists have been
involved in studies of the physics
and chemistry of soils, and can trace
the movement and chemistry of
these pollutants in the soil. Thus,
the project leadership is being di
rected by Brown.
Major project objectives are to
evaluate and analyze pollutants, in
cluding organic carbon, ammonia,
nitrite, phosphates, nitrate and or
ganic nitrogen, salts and fecal bac
teria in disposal fields. The project
also will provide a series of test plots
available to EPA’s National Ground
Water Research Program at Ada,
Oklahoma, for the study of move
ment and degradation of organic
compounds in the soil.
Two septic tank disposal fields,
representing two of the three differ
ent soils in the study, will be in
cluded in the research in the Col
lege Station area. Brown indicated
that large undisturbed blocks of (inf
sand, loam, and clay soils will Ik
isolated so the quantity and quality
of drainage water can be detei
mined.
Results of the project are to Ik
used to develop recommendations
for maximum allowable densities^
septic tank systems under varied
soils and climatological conditions,
Brown notes. He will be in charged
field investigations, and WoodswiI
direct laboratory analysis work.
