Abstract:
Impact
of anticipated coal mining in UT on salinity of Price, San Rafael, Green
Rivers are
to be addressed in the repermitting of existing mines, and the
permitting
of new mines. To determine potential
impacts, mathematical models
were
developed for Price and San Rafael River basins. It was assumed that
maximum
quantity of groundwater discharged from each mine would occur
simultaneously
for all mines; thus, a worst-case condition is presented. Little
impact
on the quantity and quality of streamflow is expected in the Price and
San
Rafael Rivers.

Abstract:
The
report under the title of Crop Salt Tolerance Study - Phase II includes two
theses,
their titles are: Determination of Salinity Threshold Levels for
Selected
Grass and Legume Forage Species, by James A. Ippolito,and Determination
of
Salinity Response of Two Alfalfa Cultivars, by Malik Mohammed Al- Wardi. The
study
includes extensive experimental data. The tolerance study submits both
theses
as evidence in support of its proposition.
To
determine the salinity tolerance of crop cultivars used for hay production
and
revegetation of mined lands in the intermountain West, greenhouse
experiments
were conducted in mixtures of salt and nutrient solutions carefully
prepared
for this purpose. The main purposes of
these experiments were to
determine
if the results of experiments conducted with chloride salts can be
extended
to sulfate salts, since some regions in the intermountain West have
irrigation
waters that contain mainly sulfate salts.
The results showed that
for the
cultivars tested, there were small differences between their chloride
and
sulfate salinity tolerance. This is
fortunate, because the majority of the
experiments
found in the literature were conducted with chloride salts.
The
results also showed that most tested cultivars were sensitive or
semi-sensitive
to salinity. Therefore, waters and
soils of mining areas should
be
tested to monitor the impact of mining activities on accumulation of salts in
irrigation
water and in soils.
Results
showed that air temperature during the growing period can affect crop
tolerance
to salinity.

Abstract:
Environmental
data was collected to help evaluate whether or not salinity in
strip
mine drainage water is causing material damage to vegetation on alluvial
valley
floors or whether mine drainage effluents constitute a hazard to soil
salinity
build-up that would be expected to cause material damage to crops grown
in the
future. The environmental data
consisted of surface water discharge and
quality,
groundwater depth and quality, soils and soil analyses, crops grown,
irrigation
practices, and climatic conditions.
Areas
adjacent to active and reclaimed strip mine spoils have a potential for
causing
material damage to plants because of the increased salt content in the
groundwater. This damage potential is dependent upon
water depth, amount of
leaching
by snowmelt, and vegetation type. The
soil analyses reported in
Section
II in the following report are from samples taken prior to 1980 to
obtain
mining permits. It is recommended that
soil profiles be sampled
periodically
on AVF adjacent to spoils to determine if there is a corresponding
increase
in root zone salinity with increased groundwater salinity. Also, it is
recommended
that the reliability and frequency of groundwater analyses be
increased
along with depth measurements. If the
accuracy and reliability of
electrical
conductivity measurements cannot be improved, then TDS measurements
should
be increased.
Plant
damage by salinity generally does not decrease the yield according to a
simple
average of soil salinity in the root zone.
A time-weighted combined
average
of irrigation water salinity plus soil salinity in the zone of maximum
water
uptake has been found to be a better predictor of crop yield.
