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.
