Factors That Contribute To Turbidity On The West Fork Of The White River In Arkansas, Chris Cotton, Brian Haggard
Factors That Contribute To Turbidity On The West Fork Of The White River In Arkansas, Chris Cotton, Brian Haggard
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
The West Fork of the White River (WFWR) exceeds the water quality standard for turbidity (10 NTU) set by the Arkansas Department of Environmental Quality and, since 1998, the river has been on Arkansas’s 303 (d) list of impaired water bodies unsuitable for aquatic life because of turbidity exceedances. To understand the factors that could be related to turbidity, total suspended solids (TSS), total inorganic suspended solids (TISS), total volatile suspended solids (TVSS), sestonic chlorophyll-a (Chl-a) concentrations, and turbidity were measured on three sample dates from nine sites on the WFWR. As the site location changed in the downstream direction, …
Plant Growth In Soil Amended With Drilling Mud, Satoshi Takaki, Duane C. Wolf
Plant Growth In Soil Amended With Drilling Mud, Satoshi Takaki, Duane C. Wolf
Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences
Extraction of natural gas generates drilling fluid and drilling mud that contain high concentrations of salts. Land application of the fluid and mud can have negative impacts on plant growth and soil properties. The objective of this study was to determine the effects of drilling mud on plant growth, plant chemical concentrations, and soil chemical properties. Sudangrass (Sorghum sudanense [Piper] Stapf [Piper]) and bermudagrass (Cynodon dactylon L.) were grown in a Roxana loam soil amended with 0%, 5%, or 10% (w/w) drilling mud in a 6-wk greenhouse study. Plant biomass production and concentrations of elements in biomass were determined. Electrical …
