It is a survey term short for "Bench Mark", which is a reference when setting up survey equipment to a fixed object to get all survey shots consistent and properly geo-referenced.
Is the Well isolation line for a water well versus the septic?

Thank you. I don't know what you mean by your question. The "well" noted on the drawing is a water well. Don't know what an "isolation line" is. Maybe it's the required distance from the leach field to the well?
