Neither well <br />displayed a manganese value higher than 3.215 mg /I <br />during the water year. <br />Well HGDAL3 exceeded the boron standard (750 ug /1) <br />with a value of 920 (ug /1) in September. Due to the <br />crop species grown within the Loadout area the <br />applicable standard for boron is 5000 ug /1. <br />TDS of alluvial ground water consistently exceeds <br />10,000 mg /1, indicating "Limited Use and Quality ". <br />Leachate originating from the Loadout would lack <br />sufficient head to migrate into underlying bedrock. <br />19.
