Abstract:

The chemistry of pond waters is characterized with respect to TDS, major solute species and trace elements. Similar chemical characteristics are presented for pond bottom sediments as well as salt crystals. Comparisons with natural background concentrations in seawater and saline-sink lakes confirm findings of unusually elevated levels of boron, arsenic, selenium, molybdenum and uranium.
