Hydrogeologic And Geochemical Investigation Of The Boone-St. Joe Limestone Aquifer In Benton County, Arkansas, Albert E. Ogden
Hydrogeologic And Geochemical Investigation Of The Boone-St. Joe Limestone Aquifer In Benton County, Arkansas, Albert E. Ogden
Technical Reports
The Boone-St. Joe limestone aquifer is an important unconfined aquifer for rural residents of Benton County, Arkansas. Pumping tests indicate a large range in production capability of the aquifer. The coefficient of transmissibility and specific capacity range from 24.8 to 24640 gpd/ft and 0.03 to 30 gpm/ft, respectively. No statistical relationship at a = 0.10 was found between each of these parameters and photo-lineament proximity. Drillers' estimated well yield (gpm) also showed no relationship to photo-lineament proximity. It is therefore concluded that choosing well sites along photo-lineaments for higher production is not as reliable for karstified carbonate aquifers such as …
Water, Waste And Quality Management During Preparation And Processing Of Vegetables, W. A. Sistrunk
Water, Waste And Quality Management During Preparation And Processing Of Vegetables, W. A. Sistrunk
Technical Reports
The research was designed to test and/or develop new systems of washing, peeling and blanching, develop methods of utilization of solid wastes, and find ways to reduce wastestrength of effluent without affecting quality of vegetables for processing. The highest wastestrength of effluent from vegetable processing in the region was found in plants that were canning Irish potatoes, dry beans and hominy. The high volumes of water used for washing spinach and leafy greens and the physical damage to the washed product is one of the major problems. Repetitive washing of spinach in the same water did not affect quality as …
Study Of Cumulative Growth-Inhibiting Factors In Recycled Water For Catfish Cultivation, R. W. Raible
Study Of Cumulative Growth-Inhibiting Factors In Recycled Water For Catfish Cultivation, R. W. Raible
Technical Reports
Channel catfish were grown in tanks with integral biological filters and complete recirculation of water. After the fish had resided in the tanks for 120 days, solvent extraction was performed on a portion of the tank water. Fresh pond-raised specimen channel catfish showed decreases in their heartbeat rates of about 20 percent when exposed to the extract. This metabolic disturbance is thought to be a factor in reducing the growth rate of fish held in close confinement in recirculating systems.
