A field exploration and sampling program and a laboratory investigation have been made at the sites of selected Brine Storage Reservoirs, Village Oil Field, in Columbia County, Arkansas. An analysis of seepage loss through, or under, the retaining dikes or embankments has been made for each site studied. Based on the results of field, laboratory and office studies reported herein, it is concluded that seepage is occurring from the salt water reservoir at each of the three sites.
