Dear River and Watershed Friends,
Upper Merrimack Monitoring Program volunteers continue to produce 100% sampling at 100% of the eleven sites on the Merrimack River from Franklin to Bow and on the Pemigewasset, Winnipesaukee, and Contoocook Rivers.
Do you remember that very high count we had at Site 6 on July 13 and then at Site 1 on July 27? We checked the sites and found nothing unusual. The results from yesterday’s sampling have returned to their normal low bacteria counts. One of our working theories for why we had bacteria spikes is that algal growth created a medium for bacteria to breed. There may have been transient animal (including human animals) activity in the area just before the samples were taken. We remain vigilant.
As a reminder, the readings shown below are the number of E. coli bacteria colonies for every 100 millilitres of water. Warm blooded animals (including humans) all have E. coli in their guts. State 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|
|3 Merrimack above FWWT Plant||58.8|
|4 Merrimack below FWWT Plant||25.3|
|5 Merrimack Jamie Welch Park||27.3|
|6 Merrimack Route 4 Bypass||29.2|
|7 Contoocook at Rivco||21.6|
|8 Merrimack Sewalls Falls||42.6|
|9 Merrimack Manchester St||24.6|
|10 Merrimack Blue Seal||34.1|
|11 Merrimack Garvins Falls||18.7|
Our next and last sampling day of the season is Thursday, August 24, 2017 so you will hear from us on August 25.

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.
