The 330-acre Wells G&H site is located in Woburn, Massachusetts. The site consists of two municipal wells, which were developed in 1964 and 1967 to supplement Woburn’s water supplies. In 1979, it was discovered that the wells had been contaminated by industrial waste from neighboring properties. Both wells were shut down and a supplemental water supply was arranged for the city. Site cleanup is ongoing.
