Technical Reports
The Illinois River Basin has experienced water quality impairment from non-point source pollution for many years. This fact was well documented in the State of Arkansas' Water Quality Assessment report, the Soil Conservation Service River Basin Study, and several University of Arkansas studies. Thirty-seven sub-watersheds have been identified by the SCS in the Arkansas portion of the Illinois River basin. In the Arkansas portion of the Basin, the Illinois River, Evansville Creek, Baron Fork, Cincinnati Creek, Muddy Fork, Moores Creek, Clear Creek, Osage Creek and Flint Creek were all classified as not supporting their designated use as primary contact recreation …
Illinois River 2006, Water Quality Assessment At The Arkansas Highway 59 Bridge, Marc A. Nelson, Wade Cash, Keith Trost, Jennifer Purtle
Illinois River 2006, Water Quality Assessment At The Arkansas Highway 59 Bridge, Marc A. Nelson, Wade Cash, Keith Trost, Jennifer Purtle
Technical Reports
Automatic water sampler and a U. S. Geological Survey gauging station were established in 1995 on the main stem of the Illinois River at the Arkansas Highway 59 Bridge. Since that time, continuous stage and discharge measurements and water quality sampling have been used to determine pollutant concentrations and loads in the Arkansas portion of the Illinois River. This report represents the results from the measurement and sampling by the Arkansas Water Resources Center -Water Quality Lab for January 1, 2006 to December 31, 2006.
Continuation Of Water Quality Monitoring Of The Osage Creek Above The Highway 112 Bridge Near Cave Springs, Arkansas, Marc Nelson, Luanna Diffin

Technical Reports
The City of Rogers is one of the fastest growing communities in Arkansas. Located in Northwest Arkansas, Rogers lies in two primary watersheds; the Illinois River Watershed and Beaver Lake Watershed. The Illinois River Watershed receives municipal wastewater discharge from most of the metropolitan communities in Northwest Arkansas, along with nonpoint source urban and agricultural runoff. The Illinois River originates in Arkansas and flows west into Oklahoma where it is classified as a scenic river. The river has been a source of interstate disputes for a number of years. A federal interstate compact commission was established to mediate these disputes, …

Water Quality Sampling, Analysis And Annual Load Determinations For Tss, Nitrogen And Phosphorus At The Washigton County Road 195 Bridge On The West Fork Of The White River 2003 Annual Report, Marc Nelson, L. Wade Cash, Sandi Formica
Water Quality Sampling, Analysis And Annual Load Determinations For Tss, Nitrogen And Phosphorus At The Washigton County Road 195 Bridge On The West Fork Of The White River 2003 Annual Report, Marc Nelson, L. Wade Cash, Sandi Formica
Technical Reports
A water quality sampling station was installed at the Washington County road 195 bridge on the West Fork of the White River just above the confluence of the three main forks of the Upper White River in December 2001. The Quality Assurance Project Plan (QAPP) was approved by EPA Region six on March 2002 and sampling was begun at that time. This station is coordinated with a USGS gauging station at the same location. This station was instrumented to collect samples at sufficient intervals across the hydrograph to accurately estimate the flux of total suspended solids, nitrogen and phosphorus into …
Stormwater Pollution Prevention Bmp Workshop, Demonstration, And Evaluation, Findlay G. Edwards
Stormwater Pollution Prevention Bmp Workshop, Demonstration, And Evaluation, Findlay G. Edwards
Technical Reports
With the recent promulgation of Phase II of the National Pollution Discharge Elimination System (NPDES) Stormwater Pollution Control regulations, many construction companies, consulting engineers, architects, and regulating agency personnel are unaware of the new stormwater pollution reduction requirements. In addition, they are typically unaware of Best Management Practices (BMPs) that are available to mitigate stormwater discharge pollution and the proper methods of installing and maintaining BMPs. The Water Quality Goals and Objectives were to train engineers, contractors, architects, and governmental officials on the new Phase II Storm Water NPDES regulations and Best Management Practices available for construction projects. The Original …
Investigation Of Optimum Sample Number And Timing For Determining Pollution Loads, T. S. Soerens, Marc A. Nelson
Investigation Of Optimum Sample Number And Timing For Determining Pollution Loads, T. S. Soerens, Marc A. Nelson
Technical Reports
In order to determine the impacts of non point source (NPS) pollution and to develop Total Maximum Daily Loads (Tr\tfDLs), accurate measurements of pollution loads in streams are critical. The objectives of this study were to accurately detemline pollutant loads at two sites by intensive storm sampling, to develop sub-sampling and other data analysis techniques, to detemline the effect of sample interval on load calculation accuracy, and to find the minimum sample interval required to determine storm loads at a required accuracy. The two stream sites used were a 1st order and a 3rd order stream in the Illinois River …
