ASM is committed to supporting the monitoring of drinking water sources to identify microbiological contamination prior to, and during, waterborne disease outbreaks to reduce the incidence of infections. In collaboration with the United States Centers for Disease Control and Prevention (U.S. CDC), ASM’s Global Public Health Programs (GPHP) have developed a comprehensive set of standard operating procedures (SOPs) and job aids specifically designed for both field and bench scientists in environmental microbiology laboratories.

The SOPs provide detailed, step-by-step protocols for a range of essential practices, including field testing, laboratory testing and basic laboratory processes. The job aids serve as concise visual aids to facilitate quick reference. Together, these documents aim to enhance laboratory efficiency and improve data quality.

The job aids were developed in 3 languages: English, French and Spanish. These documents are available as free downloads to all.

The development of these materials is supported by the American Society for Microbiology (ASM) Cooperative Agreement #NU2HGH202000079, funded by U.S. CDC. The contents are solely the responsibility of the authors and do not necessarily represent the official views of U.S. CDC, Health Resources and Services Administration (HRSA), U.S. Food and Drug Administration (FDA), U.S. Environmental Protection Agency (EPA) or the U.S. Department of Health and Human Services (HHS).
