Contact Recreation Season Bacteria Monitoring Data
Updates every Friday (April 1st – October 31st): 2019 Bacteria Report (FCOLI2019.xls)
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 upstream and downstream locations at the five other urban areas. Samples are analyzed for both fecal coliform and E. Coli bacteria.
Water User’s Bacteria Summary Data
The Water Users Data Summary contains data for the Ohio River water utilities and are combined with ORSANCO’s recreation season bacteria monitoring data.
Longitudinal Bacteria Data
Ohio River longitudinal bacteria surveys were completed as part of the Ohio River Watershed Pollutant Reduction Program. These surveys involved collecting samples for E. coli analysis approximately every five miles along the entire length of the Ohio River. Additional samples were also collected at the mouths of over 125 direct tributaries to the Ohio River.
