LEVELOGGERS

Data that was collected from Group 1 wells from January 11 - March 1, 2006 has been sent to the webmaster to be posted.

The loggers have been removed from Group 1 well locations and were placed into Group 2 well locations on March 10, 2006. Data will be uploaded from these well locations beginning the week of May 1, 2006.

Groups are created from the evaluation of data by the BGwT Technical Committee.

(NOTE: To see which wells are included in the Groups refer to the attached list at the end of this report)

The Levelogger unit that was sent out to Geotech for service has been replaced. The product was under warranty and we should be receiving it shortly.
