East River midchannel at 23rd Street

About this location:

Brooklyn, NY
The deep water sampling site around 23rd St. has mostly transitory boat traffic.

The data displayed on these pages relates to the levels of sewage indicating microbes. Even though the levels on a single days can fall within acceptable levels for Enterococcus, these locations are not necessarily acceptable for swimming. Other water quality parameters not reported on this web site such as chemical contamination and floatables should cause users to exercise caution at this site.

Rainfall data comes from wunderground.com. It is added daily to show cumulative amounts.

: Enterococcus count (under 35/100ml) is acceptable by EPA standards*
: Enterococcus count (between 35 and 104/100ml), if sustained over time, would be unacceptable by EPA standards*
: Enterococcus count (over 104/100ml) is unacceptable by EPA standards*
