Fecal contamination of natural water sources and reservoirs is a serious public health concern that requires timely detection and prevention of human exposure. 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.
