While analyses are widely available and some organizations have developed general guidance documents (ITRC 2011 & 2013, SERDP 2011 & 2014), consensus standardized approaches and methods that establish uniform guidelines, recommendations, considerations, criteria, and application principals have not been developed for end users (e.g., consultants, laboratories, or contaminated site managers). In the absence of a standard, environmental practitioners have adopted inconsistent applications of these tools which can lead to varying results across spatial and timescales, as well as from one site to another. Contaminated sites are largely growing in cost and complexity, and development and implementation of successful bioremediation mitigation strategies is dependent on consistent MBT data to assess, design, and monitor performance. The development of consensus standard documents through ASTM is paramount in meeting the needs of the remediation industry within the United States and elsewhere around the globe. The complexity and diversity of application of MBTs for bioremediation are not outlined in existing ASTM standards. The principal users of this standard will be industry project managers, regulators, consultants, laboratories, and contaminate site community stakeholders
The title and scope are in draft form and are under development within this ASTM Committee.
