    1. Solar Evaporation Ponds at the Salton Sea for Salinity Control Process, Progress, and Opportunities

    2. Agrarian Research and Management Company under contract to

    3. Solar Evaporation Ponds offer a salinity control method that is: Technically feasible Economically viable Environmentally friendly

    4. Existing solar salt ponds in operation for over 100 years

    6. Large ponds take in brine and expose it to sunlight and evaporation

    8. Pumps and gravity move the water

    9. Pilot Demonstration Project at Niland

    10. How Evaporation Ponds can Control Salinity at the Salton Sea

    11. Possible Conceptual Design for Solar Evaporation Ponds

    12. Salt is stored where it is deposited, and the pond levees are built higher to accommodate it

    13. Bittern salts may not be solid, but they make up a very small volume

    14. Progress at the Pilot Pond Project

    15. Salt formation in the crystallizer ponds

    16. Collection of brine and salt chemistry data

    17. Evaluation of seepage through berms as well as floor of ponds

    18. Solar Salt Ponds and Wildlife

    19. Wildlife Refuges in Salt Pond Habitat

    20. shallow saline water for feeding

    21. saline water produces rich food source

    22. nesting habitat

    23. Berms and islands create safe resting places

    24. Crystallizers are a refuge for resting

    25. Lands affected would be adjacent to, or close to, the existing Sea margins

    26. Potential accumulation of contaminants in concentrators and solid salt deposits Selenium Pesticides Metal residues Other agricultural chemicals such as fertilizers

    27. Advantages and Benefits Solar ponds most economical Solar salt ponds in use for over 100 years Solar salt ponds can be managed for habitat “Win – Win” situation for salinity control and habitat Alternatives available to deal with loss of water in the Sea Economic and environmental benefits to area

    28. Future of Solar Evaporation Salt Ponds at the Salton Sea Salinity problem must be addressed in order to maintain habitat values Assessment of environmental concerns is in progress

    30. Salts produced from a typical brine

    31. Results from the brine chemistry investigations
