Bacteria days: results for June 29, 2017
Dear River and Watershed Friends,
Good news: on our very first day of the season we not only had 100% sampling at 100% of our sites but the E. coli bacteria readings from yesterday are very low.
None of the eleven samples taken yesterday, June 29, 2017, from the Pemigewasset and Winnipesaukee Rivers in Franklin to the the mainstem Merrimack in Bow had levels exceeding 64.5 colonies of E. coli bacteria for every 100 millilitres of water. That’s great news for your weekend because designated swim beaches are not allowed to exceed 88 colonies and Class B waters (all of our sites are Class B waters) should be below 406 colonies. Here are the details.
| Site number and description | |
| 1 Pemigewasset | 21.1 |
| 2 Winnipesaukee | 13.0 |
| 3 Merrimack above FWWT Plant | 38.3 |
| 4 Merrimack below FWWT Plant | 27.2 |
| 5 Merrimack Jamie Welch Park | 35.5 |
| 6 Merrimack Route 4 Bypass | 72.3 |
| 7 Contoocook at Rivco | 64.5 |
| 8 Merrimack Sewalls Falls | 62 |
| 9 Merrimack Manchester St | 39.3 |
| 10 Merrimack Blue Seal | 48.8 |
| 11 Merrimack Garvins Falls | 36.4 |
Our next sampling day is Thursday, July 13, 2017 so you will hear from us on July 14.
Thank you to our wonderful Adopt-a-River Site sponsors, sample courier, site volunteers, Adopt-a-River Site sponsors, and the crew at Franklin Waste Water Treatment Plant. There would be no Upper Merrimack Monitoring Program without them.
