    Taxonomic Classification: Mesic, coated Typic Quartzipsamments
    Drainage Class: Excessively drained.
    Parent Material: Mixed loose sandy till and ice contact outwash.
    Permeability: Rapid in the solum and rapid to very rapid in the substratum.
    Available Water Holding Capacity: Low.
    Soil Reaction: Extremely acid through strongly acid throughout
    Depth to Bedrock: Greater than 65 inches.
    Seasonal High Watertable: Greater than 6 feet.
    Hydrologic Group: A.
    Hydric Soil: No.
    Flooding/Ponding Potential: Frequency and Type: None
    Duration and Months: None
    Potential Inclusions: Excessively drained Gloucester and Carver soils are similar inclusions. Well drained Barnstable, Merrimac and Canton soils are on concave and level slopes. Moderately well drained Sudbury and Newfields soils are on lower elevations.

    Soil Suitability:

    Agriculture: Poorly suited for most agricultural uses due to droughtyness and low fertility, irrigation is needed for optimal yields.

    Woodland: Poorly suited to woodland productivity due to droughtyness.

    Development: Well suited for development, major limitations related large stones and boulders which may hinder small excavation equipment.
