Water Quality of the Upper Arkansas River and Impact on Aquifer Water Quality

Lakin Meeting February 25, 2014 Don Whittemore

  • SOURCE OF SALINITY AND URANIUM IN RIVER

Main natural source: Weathering of marine Cretaceous shales containing gypsum and sulfides in Colorado. Human sources: Insignificant.

  • CAUSE OF HIGH SALINITY AND URANIUM LEVELS

Human: Concentration of dissolved salts by consumption of water by evapotranspiration associated with extensive irrigated agriculture and shallow reservoirs. Natural: In absence of human activities, salinity and uranium concentration would be 3 to 4 times lower.

  • HR 6018 & SR 1729

HR 6018 & SR 1729 HR 6018 & SR 1729 HR 6018 & SR 1729

  • Request Kansas Congressional Delegation work with Congress to provide funding and

direction to Reclamation to implement basin efforts that include:

  • Compiling information on usable sources and demands.
  • Developing basin tools.
  • System reliability and impact analyses on current and future capacity of all infrastructure.
  • Identifying adaptation strategies to improve operations and infrastructure.
  • Develop recommendations to address water quality challenges and provide safe drinking water.
  • Request state and local partners in Colorado and Kansas work with Reclamation to

complete these tasks and address the concerns regarding the contamination of the Arkansas River Basin.

GMD3 2020 Federal Legislation initiative

  • Issues:
  • Water quantity and quality in shared basin and High Plains.
  • Devastating floods reoccurring east of the High Plains expected to get worse with climate

shifts to a drier southwestern US and wetter Missouri and Mississippi river basin.

  • Struggling agricultural and rural economies.
  • Need to improve natural and man-made infrastructure for drought resiliency.
  • Ask:
  • Federal funding and partners to re-evaluate elements of the 1982 High Plains Study
  • Originally authorized in 1976 WRDA Bill.
  • An example of federal study support for feasibility of management alternatives to assure national

interest in food security and water supplies projected to year 2020.

  • Establish a set of water transfer elements from which Kansas, Colorado and western partners can work.
  • Help to conserve flood waters to address shared Ark Basin concerns and other western quality, quantity,

storage and drought resiliency needs.

Interstate Water Transfers

  • Big improvements on the High

Plains Study.

  • New water for Ark and adjacent

basins.

  • Excess storage capacities.
  • Declining energy cost projections.
  • Shared demand concerns.
