Water Quality Report May-June 2013 (1st patrol of 2013)
Riverkeeper conducts a water quality study aboard the Riverkeeper patrol boat. The primary goal of this ongoing project is to characterize and report on the highly variable conditions of the Hudson River Estuary through testing for sewage indicating microorganisms, oxygen and turbidity levels, and other indicators of water quality.
NOTE: EPA guidelines for “acceptable” vs. “unacceptable” fecal contamination levels have changed – they have been downgraded and are now LESS protective of public health.
For marine waters (salt and brackish) the old criteria scored any Enterococcus count over 104 per 100ml as “unacceptable” for primary contact, like swimming. The new criteria threshold uses 110 Entero per 100 ml, which is only a slight change – not really significant.
In fresh water (all our stations north of Peekskill) the old benchmark was 61 Entero per 100 ml. The new EPA criteria now uses 110 Entero per 100 ml in fresh water as well as marine. This change from 61 to 110 is significant and allows managers of fresh water swimming beaches to remain open with higher levels of fecal contamination – and increased risk of water related illnesses – than before.
