The investigation revealed suitable <br />injection/production zones below 75 feet and Langan <br />redesigned the production well to be more appropriate for <br />the expected volumes. <br /> <br />As part of the permitting of this well, Langan investigated <br />the lateral continuity of a semi-confining layer above the <br />untreated production zones, Langan's work on this project <br />allowed the client to realize a significant cost savings in <br />water treatment and avoid potential long-term fines for <br />violations of Florida Statutes. <br /> <br /> <br />Page 2117 <br />
