EPA Investigating Switch from Bacterial to Viral Indicator for Recreational Water Quality

The EPA is developing recreational water quality criteria (RWQC) for coliphage, a viral indicator, to ensure public health protection when recreating in water bodies that may be affected by human fecal contamination. The new criteria are expected to be released in 2018. The use of a viral indicator represents a significant change from current practice. […]


Water Quality Sleuths: Hot on the Trail for E. coli, B-theta fecal bacteria

Water quality scientists are taking advantage of new laboratory technology that allows them to more accurately trace the origins of bacteria levels in streams. New deep sequencing technologies are available to help scientists track the origin of fecal bacteria such as E. coli, B-theta and others.  New DNA deep-sequencing technology will help in determining how […]
