This project is part of Ozarks Water Watch’s Volunteer Monitoring Program, which promotes residents doing their part to keep our local waterways safe and clean for everyone to use and enjoy. Ozarks Water Watch’s goal for StreamSmart is to collect high quality, long-term base flow data by engaging local volunteers in monitoring. During monitoring, volunteers collect a water sample that is analyzed at Arkansas Water Resources Center at the University of Arkansas. Each water sample is analyzed for alkalinity, conductivity, pH, total dissolved solids, total suspended solids, total nitrogen, and total phosphorus. In the field, volunteers take an air temperature reading, a water temperature, and complete the EPA Rapid Bioassessment (Habitat Assessment) each quarter. During May and August monitoring, volunteers will measure stream discharge and complete a benthic macroinvertebrate survey. Data collected during the monitoring periods from August 2012 – November 2016 are presented in tables for each site in this report. The report is laid out in chapters by subwatershed and sites are listed in the report from upstream to downstream within the subwatersheds. Water Quality Parameter Descriptions Alkalinity Alkalinity is the water's capacity to resist changes in pH that would make the water more acidic. Alkalinity refers to the capability of water to neutralize acid. The alkalinity of natural water is determined by the soil and bedrock through which it passes. The main sources for natural alkalinity are rocks which contain carbonate, bicarbonate, and hydroxide compounds. Limestone is rich in carbonates, so waters flowing through limestone regions or bedrock containing carbonates generally have high alkalinity - hence good buffering capacity. Conversely, areas rich in granites and some conglomerates and sandstones may have low alkalinity and, therefore, poor buffering capacity. Alkalinity

Martin Ozarks Environmental and Water Resources Institute Missouri State University Springfield, MO January 21, 2010 INTRODUCTION The Upper White River Basin Foundation (UWRBF) implemented a water quality monitoring program in the Upper White River Basin in 2008 (www.whiteriverbasin.org). The goal of this program is to provide a long-term and consistent source of water quality and stream health information on the major rivers and tributaries draining into the upper portion of the White River including Beaver Lake, AR, Table Rock Lake, MO, and Bull Shoals Lake, MO/AR. It involves several partners including the United States Geological Survey (USGS), University of Arkansas-Fayetteville, Bull Shoals Field Station (BSFS) at Missouri State University-Springfield (MSU), and Ozarks Environmental and Water Resources Institute (OEWRI) at MSU. The Ozarks Environmental and Water Resources Institute at Missouri State University (oewri.missouristate.edu) is responsible for protocol development, data collection, and trend analysis to support the geomorphology and watershed source monitoring components of the basin-wide stream monitoring program in the Upper White River Basin in Missouri and Arkansas (Figure 1).

    August 17, 2009 Rodney Reynolds, Manager Madison County Water Facilities Board P.O. Box 606 Huntsville, Arkansas 72740 RE: Madison County Water Line Installation Project AFIN: N/A NPDES Permit No.: ARR150000 Dear Mr. Reynolds: On August 13, 2009, I performed a stormwater discharge permit compliance inspection of the above-referenced project in response to a complaint. The complainant was concerned that various permits required for the construction project may not have been obtained. The inspection was conducted in accordance with the provisions of the Federal Clean Water Act, the Arkansas Water and Air Pollution Control Act, and the regulations promulgated thereunder. This inspection revealed the following violations: 1. The Notice of Coverage (NOC) was not posted in a publicly accessible location near where construction is actively underway as required for linear projects. This is in violation of Part 1.B.8.C of the permit. Copies of the NOC should be posted at each active construction location. During our phone conversation today, you stated that this phase of the project will ultimately disturb less than 5 acres. As such, your construction project is automatically covered by the permit. A copy of the NOC can be obtained from the Water Division’s Construction Stormwater webpage. 2. A Stormwater Pollution Prevention Plan (SWPPP) was not prepared prior to commencement of construction activity. This is in violation Part II.A of the permit. A SWPPP must be prepared and implemented in accordance with Part II.A of the permit, and the plan must follow the order outlined in Part II.A.4-7 of the permit.
