Maine Geological Survey

COVID-19 Update

All Maine Geological Survey staff are available during these changing and uncertain times. Many of our staff are currently engaged in field work and are out of the office several days a week. To balance customer service, field work, and a continuing need for caution in social interactions, we ask that you conduct business on the phone and/or via email if possible. If you would like to meet with a staff person in the office or onsite, please schedule an appointment ahead of time to ensure that someone will be available to assist you. State employees and visitors are currently required to wear face masks when meeting in person in our office.
