Evaluations to determine feasibility for onlot sewage disposal systems and stormwater infiltration.  Involves the review and interpretation of soil profiles, typically exposed in test excavations.   May be followed by percolation testing to determine rates for sizing drainfields, or testing to establish permeability rates for stormwater infiltration.  Evaluations are tailored to the clients' needs and performed to satisfy applicable regulatory and code requirements.  Morphologic evaluations are intended specifically for sites with shallow limiting zones or where drip irrigation is proposed.
