Soils testing involves two (2) phases:
Phase I includes a deep soil probe
(deep hole(s) dug with a backhoe) where the Sewage Enforcement Officer (SEO)
will evaluate the soils and determine a limiting zone, which may be defined by
but is not limited to solid bedrock and indicators of a seasonal high water
table. This phase of testing costs $275
plus the cost of backhoe. If this test
fails Phase II testing will not be performed.
Other items that may fail your lot for further testing include:
·
Slopes of 25% or more over most of the lot.
·
Inadequate area for a septic system due to
proximity of nearby features. These
distances (for the absorption area) include but are not limited to:
1) Property
line, easement or right-of-way – 10 feet
2) Occupied
buildings, swimming pools and driveways – 10 feet
3) Streams,
lakes or other surface waters – 50 feet
4) Water
supply well (includes geothermal wells) – 100 feet
5) Surface
drainageways – 10 feet
6) Stormwater
seepage beds – 10 feet
Phase II includes the percolation
test, normally six small (6 inches in diameter) holes to a depth of 20 inches,
to be performed by the SEO. The holes
must be dug by others and access to water provided during the test. This phase of testing costs $300.
If testing fails a letter will be
provided to the lot owner indicating it has failed and the reasons for the
failure. Likewise, if the testing passes
a letter will be provided stating it has passed.
