TOLEND RD

The Dover Municipal Landfill is a 50-acre inactive landfill located on Tolend Road, in the Mallego Plains section, in the western corner of Dover, NH. Owned and operated by the City since 1960, the landfill initially accepted domestic refuse from Dover, but by the mid-1960s, took in industrial wastes and loose trash from both Dover and Madbury. Buried materials include leather-tanning wastes, organic solvents, municipal trash, and sludge from the Dover wastewater plant. It is believed that drums were no longer accepted after 1975. In 1977, the State installed monitoring wells around the area and found that organic solvents were entering the ground water, posing a potential threat to nearby residential wells and public water supplies for Dover and Portsmouth. The State and the Dover City Council ordered the landfill closed in 1980. The site is in a rural, residential area. There are 50 homes within 1 mile of the landfill, and the surrounding area is used for hunting and berry picking. Two water supplies are potentially at risk: the Calderwood municipal well, located a 1/2 mile north of the site, which supplies 20 percent of Dover's water; and the Bellamy Reservoir, located 1/3 mile south of the site, which supplies the cities of Portsmouth, Newington, New Castle, Greenland, and portions of Rye, Madbury, and Durham. Both of these water supplies remain unaffected by the landfill. A groundwater extraction system now encircles the landfill intercepting and removing contaminated groundwater flowing from the landfill. The landfill now resembles a large open meadow.
