In <br />areas with high evaporation, ground-water storage offers the distinct <br />advantage of relatively little or no evaporation losses. When suitable <br />sites for surface reservoirs are not available, the most important <br />advantage of artificially recharging ground water is the vast volume <br />of storage capacity in many of our naturally occurring ground-water <br />aqui fers. <br />
