Rapid Detection Methods
Traditional microbiological methods for detecting fecal-indicator bacteria and pathogenic organisms can take at least 18 hours to obtain results. Because water quality can change significantly during this timeframe, the safety of the water may not be accurately assessed. The need for rapid detection methods that provide reliable results of the current day’s water-quality conditions is widely recognized.
The USGS Ohio Water Science Center is currently testing two rapid detection methods that are being used in a variety of applications, including rapid assessment of recreational water quality, direct detection of pathogens, and microbial source tracking.
