Marion sits on Sippican Harbor, west of the Cape Cod Canal, on the mainland side of the bridge.
A company is numbered when its own site, or an existing Solvo record, confirms commercial pest control and the Cape Cod file already holds a Solvo Score. Town pages also require the town by name. Confidence tier leads the sort.

Same rubric as every scored page on Solvo Index: six weighted categories, scored 0 to 10 against fixed anchors, combined into a Solvo Score from 0 to 100 and capped at 97.0. Evidence completeness sets the confidence tier: HIGH at 90% and above, MEDIUM from 70 to 89%, LOW below 70%. A connected operating system carries a Verified tier above HIGH.
