Recreational and environmental waters can become polluted when animal and human wastes enter waterways through **aging sewer infrastructure, stormwater runoff, and both intentional and unintentional contamination events**. Microbial Source Tracking (MST) helps identify whether contamination originates from **human sources, livestock, wildlife, or pets**, enabling faster response, targeted remediation, and informed decision‑making.   ### In This Info Sheet, You’ll Learn: - Common sources of sewage and fecal contamination - Public health risks associated with contaminated recreational waters - How Microbial Source Tracking supports investigation and prevention efforts - Practical insights for environmental monitoring and response programs   ![Legionella-bacteria](https://info.pacelabs.com/hs-fs/hubfs/Legionella-bacteria.jpg?width=375&height=281&name=Legionella-bacteria.jpg)   **Download the Sewage Contamination & Microbial Source Training Info Sheet** to understand how science‑based testing can help safeguard water quality and reduce exposure risks. ##### ANALYTICAL + ENVIRONMENTAL ANALYTICAL + ENVIRONMENTAL - [Analytical + Environmental](https://www.pacelabs.com/analytical-environmental/) - [Emergency Services](https://www.pacelabs.com/analytical-environmental/emergency-disaster/) - [Statement of Qualifications](https://info.pacelabs.com/hubfs/Statement%20of%20Qualifications/Pace%20SOQ.pdf) ##### LIFE SCIENCES LIFE SCIENCES - [Life Sciences Page](https://www.pacelabs.com/life-sciences.html) - [CDMO/CRO Services](https://www.pacelabs.com/life-sciences/cdmo-cro-services/) - [Central Laboratory Services](https://www.pacelabs.com/life-sciences/central-laboratory-services/) - [Medical Device](https://www.pacelabs.com/life-sciences/medical-device/) ##### PROFESSOINAL SERVICES PROFESSOINAL SERVICES - [Professional Services](https://www.pacelabs.com/professional-services/) - [Regulatory & Compliance](https://www.pacelabs.com/professional-services/regulatory-and-compliance/) - [Scientific Staff](https://www.pacelabs.com/professional-services/scientific-staff/) - [Instrument Services](https://www.pacelabs.com/professional-services/instruments/) - [Facility Qualification](https://www.pacelabs.com/professional-services/facilities/) ##### OTHER OTHER - [Company](https://www.pacelabs.com/company/) - [Careers](https://www.pacelabs.com/careers/) - [Contact](https://www.pacelabs.com/contact-us/) - [Privacy Policy](https://www.pacelabs.com/legal-notice.html) Copyright © 2026 Pace®
