<DIV>
<DT><I>Abstract:</I></DT>
<PRE ID="original">A one-year sampling program is being conducted to assess the current chemical and physical conditions in the Salton Sea. Analyses include general physical conditions and water quality parameters, nutrients, trophic state variables, major cations and anions, trace metals and organic compounds. Samples are collected from three locations in the main body of the lake and from the three major tributaries. 
Nutrient concentrations are high and lead to frequent algal blooms, which in turn contribute to low dissolved oxygen concentrations. The tributaries have a much lower salt content, but consist primarily of agricultural return flows with high nutrient levels. Concentrations of trace metals and organic compounds do not appear to be of major concern.</PRE>
<SCRIPT>fix(original)</SCRIPT>
</DIV>
<DIV>
<DT><I>Purpose:</I></DT>
<PRE ID="original">Once monitoring has been completed, data will be used to develop information on nutrient and suspended solids loading to the Salton Sea. The geochemical model, PHRQPITZ, will be used to evaluate potential chemical reactions limiting the solubility of selected water quality variables.</PRE>
