UNC Chapel Hill Permit <br /> 1. Particle size distribution; <br /> m. Depth of water table; <br /> n. Moisture content; <br /> o. Effect of stratification on unsaturated flow; <br /> p. Infiltration; <br /> q. Evapotranspiration; <br /> r. Storage capacity; <br /> s. Vertical flow rate; and <br /> t. Mineral content. <br /> 3. Surface Water and Sediment <br /> The Permittee shall conduct a program to characterize the surface water bodies in the <br /> vicinity of the facility. Such characterizations may include, but not be limited to, the <br /> following activities and information: <br /> a. Description of the temporal and permanent surface water bodies including: <br /> i. For lakes and estuaries: location, elevation, surface area, inflow, outflow, <br /> depth, temperature stratification, and volume; <br /> ii. For impoundments: location, elevation, surface area, depth, volume, <br /> freeboard, and construction and purpose; <br /> iii. For streams, ditches, and channels: location, elevation, flow, velocity, depth, <br /> width, seasonal fluctuations, flooding tendencies (i.e., 100 year event), <br /> discharge point(s), and general contents. <br /> iv. Drainage patterns; and <br /> v. Evapotranspiration. <br /> b. Description of the chemistry of the natural surface water and sediments. This <br /> includes determining the pH, total dissolved solids, total suspended solids, <br /> biological oxygen demand, alkalinity, conductivity, oxygen demand, total organic <br /> carbon, specific contaminant concentrations, etc. <br /> c. Description of sediment characteristics including: <br /> i. Deposition area; <br /> ii. Thickness profile; and <br /> iii. Physical and chemical parameters (e.g., grain size, density, organic carbon <br /> content, ion exchange capacity,pH, etc.) <br /> B-8 <br />
