ABSTRACT
The net effect of evaporation ponds uses at EMISAL is to concentrate all the
dissolved components. The basic principals of the evolution of the lake and pond brines are
discussed here on the basis of the buildup of the dissolved components through evaporation
as a major control on the brine composition. The salinity (Total Dissolved Solids) values ,
concentration of the major cations and anions (Ca
+2
, Mg
+2
, SO4
-2
, Na
+
and Cl
–
) , ions and
molecular ratios (Mg
+2
/Ca
+2
, mMg
+2
/ mCa
+2
, Na
+
/ Mg
+2
, m Na
+
/m Mg
+2
) are discussed.
The type of Lake Quaroun water and fourth pond brine are detected.
