Updates on Fridays: 2016 Bacteria Report (FCOLI2016.xls)
Recreation Season Bacteria Monitoring Data
During the contact recreation season (April-October), ORSANCO monitors bacteria levels in six urban areas along the Ohio River. Samples are collected at upstream, downtown, and downstream locations in Cincinnati. Samples are also collected at downtown and downstream locations at the five other urban areas. Samples are analyzed for both fecal coliform and E. Coli bacteria.
Longitudinal Bacteria Data
Since 2003, several Ohio River longitudinal bacteria surveys have been completed as part of the Ohio River Watershed Pollutant Reduction Program. These surveys involve collecting samples for E. colianalysis approximately every five miles along the entire length of the Ohio River. Additional samples are also collected at the mouths of over 125 direct tributaries to the Ohio River.
Water User’s Bacteria Summary Data
The bacteria file (2001-2015 Water Users Data Summary) contains data for the Ohio River water utilities and are combined with ORSANCO’s recreation season bacteria monitoring data.
