Westford student gets commission OK to test low-cost LakeGuard water sensor at Burges Pond
Summary
A Westford Academy freshman demonstrated a $25–30 solar-powered prototype that reads temperature and turbidity; the Conservation Commission approved a limited test at Burges Pond from April 15–Sept. 15, 2026, with coordination advised with the Board of Health.
Raul Ram, a Westford Academy freshman, presented a prototype called LakeGuard — a solar-powered device with sensors for temperature and turbidity meant as early indicators of water contamination. Commissioners asked about data collection, signage, placement and vandalism protection; Salem advised coordinating with the Board of Health.
The commission voted 7-0-0 to allow testing of the device at Burges Pond from April 15 through September 15, 2026. Ram said the prototype "costs about $25-30" and can be replicated at low cost, and an experienced sampler in the meeting, Ali Walter, offered support for deployment and location advice.
