Optimizing Injection Strategies and In situ Remediation Performance (OIS-ISRP-1, 2020) focuses on improving the effectiveness of in situ remediation technologies that treat contamination by injecting amendments into soil and groundwater. While these technologies can successfully address a wide range of contaminants, site conditions, amendment selection, and delivery methods can limit their performance. The guidance emphasizes understanding site characteristics and designing remediation approaches that fit site-specific conditions to improve the likelihood of success.
This guidance provides practical recommendations for planning, designing, implementing, and evaluating in situ remediation projects. It highlights the importance of site characterization, amendment selection, injection design, performance monitoring, and ongoing optimization throughout the life of a project. The document also addresses regulatory considerations, stakeholder engagement, common implementation challenges, and lessons learned from case studies, helping practitioners improve remedial performance and achieve cleanup goals more effectively.
