Water Testing Results
Summer 2003

Merrimack and Souhegan Rivers
E-Coli Bacteria in Colonies per 100 ml. of Sample

Bacteria levels below 88 colonies per 100 ml. are considered safe for public swimming areas. Therefore levels above 88 colonies per 100 ml. are colored in red.

TNC: To numerous to count.

N/A: Entries labeled N/A are not available. The e-coli counts are usually not available because no one collected the water sample. There may be no volunteer for a particular site, or a volunteer might have been out of town or unable to collect the sample. If you wish to help reduce the number of N/A entries and can collect a few water samples on a Tuesday morning, call George May at 883-3409 or email georgemay (at) msn (dot) com.
