Massachusetts Soil Drainage Rankings
How well does the soil drain across Massachusetts? We ranked every USDA survey area by the percentage of land classified as "well drained." Areas at the top of the list have soils where water moves through at a healthy rate — favorable for building, septic, and gardening. Areas at the bottom have more waterlogged or slowly-draining soils that may require engineered solutions.
The best-drained survey area is Franklin County, Massachusetts at 67% well-drained soils. The most drainage-challenged is Nantucket County, Massachusetts at 13%.
