Remediation of Brine Spills – What Goes Wrong

For 20 some odd years I have taught soil remediation workshops to the oil and gas industry. During this time I have also conducted many brine spill remediation projects myself, many as a volunteer for The Nature Conservancy on the Tallgrass Prairie Preserve in Oklahoma. Over the years I have seen many successful projects, but I have also seen many attempts at remediation that have failed. Many of these failures started as manageable sites, but after one or more misguided attempts at remediation, the sites became more difficult to treat and more costly to remediate. In this talk I will review what, in my opinion, represents the most common mistakes made in brine spill remediation and the consequences of these mistakes. I will also review what I believe to be the most important lessons learned in remediation of brine spills. Topics will include the importance of organic matter, achieving adequate drainage, providing calcium, the role of water, and revegetation. Let’s make this a conversation; we can all benefit from an exchange of ideas and opinions.
