Back River Bacteria Monitoring This MPN means the most probable number out of the highest it can max out within the system we use. The highest number for the dilution we run would be 241,900. According to the State of Maryland, it's unsafe to come into contact with surface waters if the enterococcus level is greater than 130 MPN/100mL. Here's a link to a reference for that: http://www.dsd.state.md.us/comar/comarhtml/26/26.08.02.03-3.htm
