The Department of Health and Environment was established in 1926 to provide regional efficiencies throughout the 15 towns of Barnstable County, while supporting the autonomy of local boards of health. The Department provides a diversity of services that promote public health and environmental protection, from emergency planning, to monitoring of water, land, and air, to disease prevention, inspectional services, COVID-19 pandemic response, and even the practical application of providing loans for septic system repair and replacement. The physical and mental well-being of Barnstable County’s residents, alongside protection of our sensitive ecosystems, are our top priorities.
