The pump-and-treat method of remediation has been regarded for years as unsuccessful and untrustworthy. But a recent project in Chicago showed that in conjunction with horizontal wells and soil venting that pump and treat is a viable remediation alternative. The project began in February 1993 on the site of a telecommunications manufacturing plant. Heating oil and fuel from underground storage tanks had leaked and contaminated the site. Two horizontal wells were installed and the site's condition has continually improved. This paper describes the installation of the remediation system and argues for use of pump and treat under the right circumstances.
