In New Hampshire, there are some fishing spots to watch out for: According to DES (http://des.nh.gov/) fish from several water bodies in the state have been shown to have higher than average mercury concentrations.
For the water bodies below, DES says, “sensitive populations should not consume any fish,” and others should limit consumption to two meals a month:
• Ashuelot Pond in Washington
• Comerford and Moore reservoirs on the Connecticut River
• Crystal Lake in Gilmanton
• Dubes Pond in Hooksett
• Jackman Reservoir in Hillsboro
• Mascoma Lake in Enfield
• May Pond in Washington
• Tower Hill Pond in Candia
And, DES says, no one should eat fish from the Androscoggin River from Berlin to the Maine border because of potential dioxin contamination.
