<strong>the</strong> o<strong>the</strong>r half comes from deep underground br<strong>in</strong>es <strong>in</strong> Cali<strong>for</strong>nia, Utah, and<br />

Arkansas. In a typical case, a s<strong>in</strong>gle well flow<strong>in</strong>g at a rate of 20,000 bpd,<br />

and a brom<strong>in</strong>e content of 65 ppm could yield -450 lb (100% extraction) of<br />

brom<strong>in</strong>e, with a market value of -$250/day. The concentrated br<strong>in</strong>es from<br />

desal<strong>in</strong>ation effluent are rich sources of various chemicals (Figure 9) whose<br />

economic extraction may be best accomplished by way of accumulation <strong>in</strong> solar<br />

ponds from which harvest<strong>in</strong>g and process<strong>in</strong>g of <strong>the</strong> various salts could be<br />

undertaken as at <strong>the</strong> Great Salt Lake <strong>in</strong> Utah.<br />
