We are basing our decision on the information provided in the Potomac Riverkeeper webinar on February 11th. During the webinar, the Riverkeeper, a watchdog group, shared data collected in partnership with the University of Maryland showing elevated E. coli levels near the spill site (up to ~4,000 times safe levels) and several miles downriver. They also found Staph and MRSA (antibiotic-resistant Staph) near the spill site and Staph at several stations downriver. As of last week, the area off WSM appears to be within EPA safe limits for E. coli.
However, the Riverkeeper emphasized that the spill situation is very much in flux: additional releases are possible as DC Water continues to make repairs over the next 4-6 weeks, and there are many uncertainties related to how melting ice and increasing temperatures will impact water quality in the river, especially downstream. Critically, there are no public agencies regularly sampling the water (e.g., daily) at multiple locations downriver, nor are any state or federal entities (with the exception of MD) stepping up to issue public health advisories. Without trusted data and information available on a regular basis, it is impossible to be confident that our sailing area is safe on a given Sunday. This shouldn't be the case, but unfortunately, it is.
There is much more to this story as noted in the attached summary, which also includes a link to the recording.
