The Health Department is committed to protecting public health and ensuring compliance with a broad range of health and safety regulations. We oversee food service establishments, septic systems and well construction, lodging facilities, public swimming pools, recreational camps for children, residential and lodging housing standards, and tobacco control regulations.
We also investigate nuisance complaints, report and disseminate information on communicable diseases, monitor water quality at Margaret Lindley Park, and regularly update the town’s public health emergency preparedness plans. In addition, we work closely with the Building Inspectors to ensure compliance with permits that involve both departments.
