San Salvador has complex water tables and surface water formations. The chemical composition of surface water is determined by rates of evaporation, precipitation and dissolution, as well as by inputs from conduits, tides, and channels from nearby lakes. Six water bodies were chosen for analysis of pH, salinity, dissolved oxygen, temperature, nitrate, phosphate and selected cations. They fell into two categories (confirmed by Mg/Ca ratios and thermal imaging): non-conduit-associated lakes influenced by relative rates of precipitation and evaporation that result in higher than seawater salinities, and conduit-linked lakes with salinity, temperature and pH values close to those of seawater.
