Hanover and state environmental and public health officials will gather in the town together publicly for the first time Nov. 14 to address the impact and resolution of the contaminated 240-acre National Fireworks site. 

Six decades of manufacturing civilian fireworks and later US military munitions for four wars have resulted in enough mercury, lead, and other chemicals in the soil, wetlands, and adjoining waterways to earn the parcel one of the highest hazardous designations in the state.
