Sorption and leaching characteristics of heavy metals in artificial soil
(University of Missouri--Columbia, 2006)
The objective of this study was to investigate the heavy metal sorption and leaching characteristics of an "artificial soil" formed by blending industrial and municipal by-products and implemented as a beneficial waste ...
Geotextile wrap-face wall using marginal backfill
(University of Missouri--Columbia, 2006)
A concrete retaining wall was constructed during October/November 2005. The height of the wall was 9 feet with a stem width of 0.83 ft, while the width of the base was 1.83 ft. The backfill was a low plasticity clay (CL). ...
Geotextile separators for dust suppression on gravel roads
(University of Missouri--Columbia, 2006)
Dust can be a health concern because of its potential to contain respirable particles. The US EPA and state environmental agencies developed and implemented a reporting system for the amount of particulate (PM10) derived ...
Use of fluorescence excitation emission matrix spectroscopy for water and wastewater characterization
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The Excitation Emission Matrix Spectroscopy (EEMS) has the potential to be used for the real time monitoring of environmental effects on water and ...
Pre-harvest water quality of ephemeral streams in Missouri Ozark forests
(University of Missouri--Columbia, 2006)
The Missouri Department of Conservation (MDC) developed a best management practice that leaves a riparian buffer next to streams to reduce the possibility of water quality degradation. The purpose of this study is to ...
Tensile strength, shear strength, and effective stress for unsaturated sand
(University of Missouri--Columbia, 2006)
It is generally accepted in geotechnical engineering that non-cohesive materials such as sands exhibit no or negligible tensile strength. However, there is significant evidence that interparticle forces arising from capillary ...
Development and evaluation of innovative iron-containing porous carbon adsorbents for arsenic removal
(University of Missouri--Columbia, 2006)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Arsenic is of serious concern because of its marked negative impacts to human health. Of the various sources of arsenic in the environment, drinking ...
Formation studies on N-nitrosodimethylamine (NDMA) in natural waters
(University of Missouri--Columbia, 2006)
N-nitrosodimethylamine (NDMA) is a chloramines disinfection by-product and probable carcinogen to human. The California state established a 10 ng/L action level for NDMA in drinking water. Analytical method of NDMA in ...
Field performance of instrumentation for monitoring effects of timber harvesting on water quality
(University of Missouri--Columbia, 2006)
Water samples from ephemeral streams and associated hillsides are being collected to quantitatively determine the impact of Regenerative Oak Clear Cutting (ROCC) on water quality and sediment and nutrient transport in ...
