Water Quality

Westford’s primary drinking water aquifer underlies the Stony Brook watershed. There are fourteen public water supply wells in this watershed. There are six public water supply wells scattered through the southern portion of the Nashoba Brook watershed. Protection of lands associated with these drinking water aquifers is critical to sustaining surface and groundwater quality and quantity.  -Watershed Action Plan for Town of Westford, 2007

Trust and community members work together as part of the water quality monitoring group, the Westford Stream Team. We have been sampling and collecting data in the Nashoba Brook and Stony Brook watersheds in some form since 2006, under the guidance and auspices of OARS (Organization for the Assabet Sudbury & Concord Rivers). Our goals are to measure and document water quality and field observations over the long term to provide potential trend analysis. We also provide this data to town and state agencies for further analysis if needed. Funding is provided by the town through our annual request to the Conservation Commission.

We usually sample monthly from March/April to November and our analysis includes dissolved oxygen, pH, water temperature, phosphorus, nitrogen (nitrates), conductivity & river (stream) field observations. We are always looking for volunteers to help us monitor water quality in our major streams and tributaries here in Westford. If you are interested in joining our effort, email us at waterquality@westfordconservationtrust.org or contact us for more info!

Wetlands

As we protect our wetlands, we protect our drinking water. Rain which falls drains to wetlands and slowly percolates into the groundwater. If there were no wetlands to absorb rain, water would flow directly and swiftly into our rivers and out of Westford, depleting our drinking water aquifers. See how wetlands work.

Global Warming
Global warming and the resultant climate change is a complex issue. It is both a scientific and a conservation matter that affects us here in Westford. We believe that education is a critical part of the remedy. We propose twelve actions you can start taking today. What is at stake is nothing less than our planet’s future.  Read our brochure.
