Wassaic soils formed in till and are moderately deep to limestone. Halsey soils are very poorly drained and have a seasonal high water table from September to June, unless drained. The water table ranges from 0.5 feet above the surface on level areas and in depressions to 0.5 feet below the surface on areas that are nearly level to gently sloping. Surface drainage is slow because of inadequate outlets. Halsey soils on low terraces are subject to flooding in some places.
Permeability is moderate or moderately rapid in the solum and rapid or very rapid in the substratum.
Runoff is negligible or low. Natural vegetation consists of red maple, elm, ash, willow, sedges, and rushes. Small areas have been cleared and drained, and are used as pastureland or for growing vegetables or hay. The series is of moderate extent. Warren County, New Jersey, 1951.
