NRWA 2018 Water Monitoring Dates

Water Monitoring takes place on the 3rd Saturday of every month from April through October. Volunteers deliver samples to either the Devens or Pepperell wastewater treatment facilities between 8:00 and 9:30 a.m. for testing by NRWA staff and volunteers. For directions to the labs.

Monitors are advised to listen to weather forecasts and be aware of stream conditions during heavy precipitation. Localized flooding can occur suddenly and make monitoring unsafe. Never go near streams that are in flood, where conditions seem unsafe, or if you have any concerns. Safety is the first priority!

NRWA staff will also be tracking conditions. We will cancel monitoring if we learn that weather or streams conditions are unsafe in any part of the watershed. So monitoring might be canceled even if your stream looks safe. Be sure to check before heading out! If you have questions, please call Martha or Kath’s cell phones. Also, remember to check your email late Friday afternoon before a monitoring day if you are questioning the weather or conditions. Depending on forecasts, we may not send email notification of a cancellation until mid-day on Friday. When in doubt, don’t go out!
