Description - Septic Tank Absorption Fields
Septic tank absorption fields are areas in which effluent from a septic tank is distributed into the soil through subsurface tiles
or perforated pipe. Only that part of the soil between depths of 24 and 60 inches is evaluated.The ratings are based on the
soil properties that affect absorption of the effluent,construction and maintenance of the system,and public health.Saturated
hydraulic conductivity(Ksat),depth to a water table,ponding,depth to bedrock or a cemented pan,and flooding affect
absorption of the effluent. Stones and boulders, ice,and bedrock or a cemented pan interfere with installation. Subsidence
interferes with installation and maintenance. Excessive slope may cause lateral seepage and surfacing of the effluent in
downslope areas.
Some soils are underlain by loose sand and gravel or fractured bedrock at a depth of less than 4 feet below the distribution
lines. In these soils the absorption field may not adequately filter the effluent,particularly when the system is new.As a
result,the ground water may become contaminated.
Rating class terms indicate the extent to which the soils are limited by all of the soil features that affect these uses. "Not
limited" indicates that the soil has features that are very favorable for the specified use.Good performance and very low
maintenance can be expected. "Somewhat limited" indicates that the soil has features that arc moderately favorable for the
specified use.The limitations can be overcome or minimized by special planning,design,or installation.Fair performance
and moderate maintenance can be expected. "Very limited"indicates that the soil has one or more features that are

design,or expensive installation procedures.Poor performance and high maintenance can be expected.

Description - Small Commercial Buildings
Small commercial buildings are structures that are less than three stories high and do not have basements. The foundation is
assumed to consist of spread footings of reinforced concrete built on undisturbed soil at a depth of 2 feet or at the depth of
maximum frost penetration,whichever is deeper.The ratings are based on the soil properties that affect the capacity of the
soil to support a load without movement and on the properties that affect excavation and construction costs. The properties
that affect the load-supporting capacity include depth to a water table,ponding,flooding,subsidence, linear extensibility
(shrink-swell potential),and compressibility(which is inferred from the Unified classification).The properties that affect the
ease and amount of excavation include flooding,depth to a water table,ponding,slope,depth to bedrock or a cemented pan,
hardness of bedrock or a cemented pan,and the amount and size of rock fragments.
The ratings are based on the soil properties that affect the risk of pollution and the design,construction,and performance of
the system.Depth to a water table,ponding,flooding,and depth to bedrock or a cemented pan affect the risk of pollution and
the design and construction of the system.Slope,stones,and cobbles also affect design and construction. Ksat and reaction
affect performance.Permanently frozen soils are unsuitable for waste treatment.
Rating class terms indicate the extent to which the soils are limited by all of the soil features that affect building site
development. "Not limited" indicates that the soil has features that are very favorable for the specified use.Good
performance and very low maintenance can be expected. "Somewhat limited"indicates that the soil has features that are
moderately favorable for the specified use.The limitations can be overcome or minimized by special planning,design,or
installation. Fair performance and moderate maintenance can be expected. "Very limited" indicates that the soil has one or
more features that are unfavorable for the specified use.The limitations generally cannot be overcome without major soil
reclamation, special design,or expensive installation procedures. Poor performance and high maintenance can be expected.
