REMINDER:

The next sampling event is

Tuesday, August 21st, 2018 at 6:00 AM

If you are unable to make the sampling event and have not already done so, please let me and your sampling partner know as soon as possible!

Dear Friend,

Attached are the E.coli results from the July sampling event, also displayed on the map below. The July sampling event was classified as a wet weather event, in which 0.32 inches of rain fell in the three days preceding the sampling event.

In July, water samples were collected and tested for E.coli at 33 out of 35 sites. All but one site passed the boating standard (630 MPN/100mL), and 73% of sites passed the swimming standard (126 MPN/100mL). The highest E. coli levels were observed at site 269T, the Stop River in Medfield, with a concentration of 637 MPN/100mL.

UMass Amherst Hydrogeology Sampling

Last summer we partnered with the Hydrogeology group at UMass Amherst to provide them with water samples from some of our sites on the Charles. This effort supported their study on the isotopic composition of surface and ground waters in the Northeast. You can read their report on last year's results from our watershed here.

This year, we will be partnering with them again to collect additional samples during August and September. The sites they have selected are:

35CS - Central St., Milford

130S - Maple St. bridge, Bellingham

229S - Rt. 115/Baltimore St., Millis

318S - Rt. 27 bridge, Medfield

400S - Charles River Rd. bridge, Dover

521S - Ames St. bridge, Dedham

567S - Nahanton Park, Newton

621S - Park Rd., Weston

662S - Moody St. bridge, Waltham

700S - N. Beacon St. bridge, Watertown

763S - Mass. Ave. bridge, Cambridge

784S - New Charles River Dam, Boston

If you sample at one of these sites, you should have received a small labelled bottle for sample collection. You can fill up the small bottle from your temperature bottle and transport it on ice to your regional drop-off site. If your site is on this list but do not have a small bottle for August, please let me know and we can arrange getting it to you.
