Constituent Loads And Trends In The Upper Illinois River Watershed And Upper White River Basin, Erin E. Scott, Zach P. Simpson, Brian E. Haggard
Constituent Loads And Trends In The Upper Illinois River Watershed And Upper White River Basin, Erin E. Scott, Zach P. Simpson, Brian E. Haggard
Technical Reports
Water chemistry can greatly influence the quality of surface waters and affect the ability for streams and rivers to meet their designated use(s). In Arkansas, many streams and rivers were placed on the 2008 303(d) list of impaired water bodies due to excess levels of nutrients, chlorides, sulfates, and sediments (ADEQ, 2008). These constituents continue to be listed as the potential cause for water‐quality impairments through the most recent draft 303(d) list (ADEQ, 2014). The Arkansas Non‐Point Source (NPS) Management Program wants to reduce poll‐ utant loading from the landscape and improve water quality, where funding for projects is targeted …
Water Quality Trends Across Select 319 Monitoring Sites In Northwest Arkansas, Bryan W. Bailey, Brian E. Haggard, Leslie B. Massey
Water Quality Trends Across Select 319 Monitoring Sites In Northwest Arkansas, Bryan W. Bailey, Brian E. Haggard, Leslie B. Massey
Technical Reports
Northwest Arkansas contains two 319 priority watersheds that the Arkansas Natural Resources Commission has identified as being impacted by point source and nonpoint source pollution (i.e., phosphorus, nitrogen, and sediment). This project specifically focused on determining water quality trends at select sites within the Illinois River (HUC# 11110103) and Beaver Reservoir (HUC# 11010001) priority watersheds, including Ballard Creek, Osage Creek, Illinois River, White River, West Fork White River and the Kings River where sufficient constituent data were available. Water quality trends were analyzed using flow‐adjusted constituent concentrations of phosphorus, nitrogen, sediment, sulfate and chloride, and parametric and non‐parametric statistical techniques …
Water Quality Outreach And Education Strategies For Northwest Arkansas And Regional Watersheds, Katie Teague, John Pennington
Water Quality Outreach And Education Strategies For Northwest Arkansas And Regional Watersheds, Katie Teague, John Pennington
Technical Reports
Stakeholders impact water quality and have a responsibility to protect, maintain, and improve water quality throughout northwest Arkansas and watersheds everywhere. But unless the roles of responsibility and stewardship among all stakeholders is communicated clearly and repetitively, there will be little progress made towards maintaining and improving water quality, while lawsuits, blame, and inaction will persist. Thus, the overall goal of water quality education and outreach is to improve the ability of stakeholders to take care of their watershed by teaching them what actions are or are not beneficial for water quality protection, maintenance, or improvements. Specific outreach and education …
Regulatory Drivers For The Upper Illinois River And Other Regional Watersheds, Ray Weida
Regulatory Drivers For The Upper Illinois River And Other Regional Watersheds, Ray Weida
Technical Reports
Environmental regulations are put in place to protect the air, water and land from threat of pollution. Regulatory programs establish pollution limits, determine compliance, and enforce environmental laws and regulations for waterbodies within the watershed based on the designated uses for the individual waterbody. These established regulations make sure that the state’s mandatory standards for clean water and the minimum federal standards are being achieved. Environmental regulations are established on both the federal and state levels. On the federal level, Congress has authorized the U.S. Environmental Protection Agency and other governmental agencies to create and enforce regulations. The EPA delegates …
Water Quality And Watershed Conditions In The Upper Illinois River Watershed, Brian Haggard, Andrew Sharpley, Leslie Massey
Water Quality And Watershed Conditions In The Upper Illinois River Watershed, Brian Haggard, Andrew Sharpley, Leslie Massey
Technical Reports
The Illinois River and its tributaries have many uses that have been designated by the Arkansas Department of Environmental Quality including fisheries, aquatic life, primary contact waters, secondary contact waters, drinking water supply, and agricultural and industrial water supply, and water quality affects whether these uses can be supported. Since water quality can be quite complex, many types of measurements can be used as water quality indicators; some common water quality measurements include pH, dissolved oxygen concentration, and conductivity. More complicated measurements include determining nutrients, sediment and bacteria in the water, as well as assessing the aquatic life—aquatic insects, fish, …
Final Report To The Illinois River Watershed Partnership: Recommended Watershed Based Strategy For The Upper Illinois River Watershed, Northwest Arkansas, B.E. Haggard, Andrew Sharpley, Leslie Massey, Katie Teague
Final Report To The Illinois River Watershed Partnership: Recommended Watershed Based Strategy For The Upper Illinois River Watershed, Northwest Arkansas, B.E. Haggard, Andrew Sharpley, Leslie Massey, Katie Teague
Technical Reports
This publication serves as the final report to the Illinois River Watershed Partnership (IRWP) regarding the project entitled “Development of the Watershed Management Plan for the Upper Illinois River”. This document was intended to provide this stakeholder based organization guidance in the development of a watershed management plan for the Illinois River drainage area (i.e., the Upper Illinois River Watershed, UIRW) in Arkansas. This document represents the final report from the Arkansas Water Resources Center (AWRC) and affiliated project investigators, and the IRWP may alter this document before the final submission of its watershed management plan to the Arkansas Natural …
A Vision For The Upper Illinois River Watershed, Kent Thornton
A Vision For The Upper Illinois River Watershed, Kent Thornton
Technical Reports
The Upper Illinois River Watershed is a special place where the threads of private, public and non‐profit partnerships are woven into the regional fabric of economic vitality; environmental stability, and social responsibility. Through its cultural heritage, the legacy of land stewardship, integrated with respect for personal property rights, continues. Natural resources are restored and sustained within a healthy mosaic of fields, forests, farms, woodlands, wetland prairies, pastures, cities, and naturally flowing streams. It is an incubator for green energy, entrepreneurial, educational and environmental initiatives.
Illinois River Volunteer Monitoring, L.B. Massey, B.E. Haggard
Illinois River Volunteer Monitoring, L.B. Massey, B.E. Haggard
Technical Reports
Understanding how water quality conditions change along a land use gradient and over time is important for sustainable watershed management. Therefore, a volunteer monitoring program was created to measure water chemistry at 37 established sites within the Upper Illinois River Watershed and to evaluate changes in water chemistry over the past 15 years. The Illinois River Watershed Partnership (IRWP), a non‐profit organization subcontracted with the Arkansas Water Resources Center at the University of Arkansas, to manage the volunteer monitoring project, train volunteers to collect samples following EPA approved methods, and to analyze the collected samples. The AWRC trained 27 volunteers …
Water Quality Considerations In The Slurry Pipelining Of Coal, James W. Moore
Water Quality Considerations In The Slurry Pipelining Of Coal, James W. Moore
Technical Reports
Interest in the use of slurry pipelines for the movement of large volumes of coal over long distances has increased rapidly during the last decade. In the early 1970's, this interest involved the movement of Western coals to markets in the southwestern and western United States. In recent years, however, interest in the use of slurry pipelines for transporting Eastern coal developed. Very little information was available concerning the water quality aspects of the slurry pipelining of Eastern coal. The research program was developed to commence building the data base in this regard. Extensive water quality investigations were conducted using …
