Explanation: Twentyntile Coal Company started supplying the Jones fancily with storage tanks and imported water in the spring of 2008, aftenvhich they ceased to utilize this alluvial well. Note that sample collected on 10/28/08 was of the imported water. A sample of alluvi al water was not available, as the original well and plumbing was sealed. • EXCEL: G9&nirmnnnnal\CDMG - CDRUS\AliR\2009\Tabi,s\weas2009..h
