Remediation of Salt-Affected Soils at Oil and Gas Production Facilities

API Publ 4663 – Remediation of Salt-Affected Soils at Oil and Gas Production Facilities

Water seperated from oil and gas during production contains dissolved solids, including salt. If improperly handled, produced water with sufficient salt concentratins can damage plants and soils. Therefore, this manual was designed to assist the oil and gas environmental professional and field personnel to (1) assess sites with salt-affected soils, (2) evaluate remedial alternatives, and (3) conduct remedial activities, if necessary. It provides forms for organizing assessment informatin and conducting sample collection and analysis. Remediation options are divided into three primary groupings: natural remediation, in-situ chemical amendment remediation, and mechanical remediation. A decision tree and worksheets are provided to aid in the selection of a remedial option(s). Technical approaches for applying each group of remedial options are discussed. A number of appendices provide supplementary information on various aspects of salt-affected remediation.
