  1. Characterization of Dissolved Solids in the Ohio River Technical Committee Meeting October 10-11, 2011

  2. Study Objectives • Characterize ambient background levels of TDS. • Develop site-specific translators to convert conductivity to TDS. • Quantify TDS constituent makeup to document temporal and spatial variability. • Provide data to support possible development of an Ohio River bromide stream criterion.

  3. Sampling Design • Weekly samples collected at 15 sites • Collection sites located at water intakes • Participants identified through the WUAC and PIAC • Sampling to begin late October • Study will run for one-year

  4. Analysis Dissolved Solids Analytes Supplemental Parameters pH Conductivity Temperature Stream flow Coordinate THM sampling when possible • Sodium • Potassium • Magnesium • Calcium • Lithium • Chloride • Sulfate • Bromide • Flouride • Bicarbonate • Total Dissolved Solids

  5. Proposed Sampling Sites Ohio River Locations (Mile) Tributary Locations (Mile) Allegheny (8) Monongahela (5) Beaver (6) Muskingum (30) Big Sandy (20) • Moon Township (12) • East Liverpool (40) • Wheeling (87) • Sistersville (138) • Dupont – Parkersburg (190) • Cheshire, OH (260) • Huntington (304) • Cincinnati (463) • Louisville (600) • Evansville (791) • Cairo (978)
