249 licensed well and septic pros based in Merrimack County. Every license number below is sourced from official New Hampshire records, with a link to verify it yourself.

Grouped by the county of the address on each business's state license record, which can be a mailing address; it doesn't tell you where the business works. Where the record doesn't name the county of the address, its ZIP code decides (a ZIP that crosses a county line goes to the county holding most of its homes), then its town.
