  <dc:description>&lt;p&gt;&lt;span&gt;Waters&amp;nbsp;&lt;/span&gt;&lt;span class="searchword"&gt;within&lt;/span&gt;&lt;span&gt;&amp;nbsp;the&amp;nbsp;&lt;/span&gt;&lt;span class="searchword"&gt;north&lt;/span&gt;&lt;span&gt;&amp;nbsp;coastal&amp;nbsp;&lt;/span&gt;&lt;span class="searchword"&gt;limestone&lt;/span&gt;&lt;span class="searchword"&gt;aquifers&lt;/span&gt;&lt;span&gt;&amp;nbsp;are suitable for public supply, industrial and agricultural uses. For the artesian aquifer and the updip parts of the&amp;nbsp;&lt;/span&gt;&lt;span class="searchword"&gt;water&lt;/span&gt;&lt;span&gt;table aquifer, calcium and bicarbonate are the dominant ionic species with total dissolved solids and chloride concentrations below 500 and 250 mg/L, respectively. In coastal areas of the&lt;/span&gt;&lt;span class="searchword"&gt;water&lt;/span&gt;&lt;span&gt;&amp;nbsp;table aquifer, where a freshwater-saltwater mixing zone occurs, the calcium bicarbonate facie grade to a sodium-chloride facie.&amp;nbsp;&lt;/span&gt;&lt;span class="searchword"&gt;Within&lt;/span&gt;&lt;span&gt;&amp;nbsp;this zone, concentrations of total dissolved solids and chloride are greater than 250 and 500 mg/L respectively, affecting the suitability of the&amp;nbsp;&lt;/span&gt;&lt;span class="searchword"&gt;water&lt;/span&gt;&lt;span&gt;&amp;nbsp;for some uses. Geochemical models were constructed to determine the physical and&amp;nbsp;&lt;/span&gt;&lt;span class="searchword"&gt;chemical&lt;/span&gt;&lt;span&gt;reasons for the prevailing&amp;nbsp;&lt;/span&gt;&lt;span class="searchword"&gt;water&lt;/span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;span class="searchword"&gt;quality&lt;/span&gt;&lt;span&gt;&amp;nbsp;patterns of the&amp;nbsp;&lt;/span&gt;&lt;span class="searchword"&gt;north&lt;/span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;span class="searchword"&gt;coast&lt;/span&gt;&lt;span class="searchword"&gt;limestone&lt;/span&gt;&lt;span&gt;&amp;nbsp;&lt;/span&gt;&lt;span class="searchword"&gt;aquifers&lt;/span&gt;&lt;span&gt;. Models indicate that calcite and carbon dioxide dissolution, precipitation or degassing are the primary processes. The mixing of recharge&amp;nbsp;&lt;/span&gt;&lt;span class="searchword"&gt;water&lt;/span&gt;&lt;span&gt;&amp;nbsp;or saltwater with aquifer waters is an important feature within the water table aquifer. The models provide further evidence that support the circulation of groundwater within the north coast limestone.&lt;/span&gt;&lt;/p&gt;</dc:description>
