Ohio Water Microbiology Laboratory
The Ohio Water Microbiology Laboratory (OWML) provides microbiological data of public-health significance from surface waters, groundwaters, and sediments across the Nation using cutting-edge analytical approaches. The OWML is a dual-function laboratory that supports internal research projects and offers analytical services to support USGS National Programs and other USGS offices.
Source Tracking

Impairments of a waterbody due to fecal contamination can be difficult to mitigate. Microbial source tracking techniques can be used to improve the understanding of contamination sources and assist with remediation efforts.
CyanoHABs

Toxins produced by cyanobacterial harmful algal blooms (cyanoHABs) are a risk to public health. Understanding more about cyanoHABs and when natural waters are under threat of developing toxic cyanoHABs is can assist in making water resource management decisions.
Nowcasting

Recreational waters can be impacted by fecal contamination and/or toxic cyanoHABs which can put the public at risk. Nowcasting uses mathematical models to determine if conditions are unsafe.
