DRILLING SERVICE CODES (HOME-SITE)
1DH)
Engineers report - Reports include a description of the parcel, the
on-site soil capabilities, load capacity, and bedrock characteristics.
2DH) Lab testing - Include grain size analysis, Atterberg limits, expansion index, classification,
compaction, density, hydraulic conductivity, moisture content, organic content
and pH.
3DH) Soil boring
- Geologic engineering tests to determine the capability of the soil to support
proposed improvements or to determine the strength and properties of a required
building foundation. Expansive clay soil or rock outcroppings may affect the
required foundation.
DRILLING SERVICE CODES (COMMERCIAL)
1DC)
Barge drilling capabilities
- Unique mounting system allows for barge drilling capabilities.
2DC) Bedrock
coring - Investigation used to analyze bedrock characteristics.
3DC) Environmental
drilling - Environmental Drilling is used to determine the existence of contamination in soil or
groundwater.
4DC) Hand auger
borings -Technique used in limited access sites, also used to create
detailed soil descriptions and hydrology characteristics.
5DC) Hollow
stem auger capabilities 2 1/4" -10 1/4" - are commonly
used to set groundwater monitoring wells for environmental and geotechnical
applications.
6DC) Low
clearance drilling - Unique equipment allows for the capability of
drilling in low clearance situations.
7DC)
Monitoring and recovery well installation - Any cased excavation or
opening into the ground, with greater depth than width, made by digging,
boring, drilling, driving, jetting or other methods for the purpose of
determining the physical, chemical, biological, or radiological properties of
groundwater. A recovery well is a unique device which allows for the removal of
the well.
8DC)
Off-road drilling capabilities (ATV) - Unique ATV equipment offer the
ability to drill on sites that would otherwise be inaccessible.
9DC)
Piezometer and inclinometer installation - A Piezometer is any cased
excavation or opening into the ground, with greater depth than width, made by
digging, boring, drilling, driving,
jetting or other methods for the primary purpose of determining the depth to,
or elevation of, the water table or potentiometric surface. An
inclinometer or clinometer is an instrument for measuring
angles of slope
(or tilt),
elevation
or inclination
of an object with respect to gravity. It is also known as a tilt meter, tilt indicator, slope
alert, slope gauge, gradient meter, gradiometer, level gauge, level
meter, declinometer, and
pitch & roll indicator.
10DC) Pressure testing - The casing pressure test evaluates the mechanical integrity of the well
casing. The well casing has mechanical integrity if there are no significant
leaks in the casing.
11DC) Probe sampling
capabilities - Drive samplers into the subsurface without the rotary action
associated with more conventional auger stems.
12DC) Professional oversite - Oversight of drilling operations focuses on ensuring that appropriate equipment is used and appropriate
practices are followed
13DC) Professional soil
profile and bedrock description - A sequential record of the soil and
geologic materials penetrated during the drilling of a borehole.
14DC) Pump testing
- To determine the sustained pumping capacity of a well a pump test must be performed
on the well. Pump tests are designed to establish
the long term equilibrium rate at which water will flow towards and enter the
well.
15DC) Shelby tube and
piston tube sampling - A shelby tube is a single-piece of metal tube, of thin gauge, which is forcefully driven into
the soil or sediment at the bottom of a borehole to collect an undisturbed
subsurface soil or sediment sample. The piston sampler is designed to collect
discrete (interval specific) samples in difficult sampling conditions, such as
flowing/heaving sands and swelling clays. The system also works well in soils below groundwater.
16DC) Split spoon soil
sampling - A multi-piece sampler which is threaded onto the end of a
drill rod or hand auger and forcefully driven into the soil or sediment at the
bottom of a borehole to collect an undisturbed subsurface soil or sediment
sample.
17DC) Registered NY
State well drilling co. with exam certified employees - Since January of
2000, NYS Environmental Conservation Law requires that "No person shall
engage in the business of
water well drilling in the state of New York without first obtaining a
certificate of registration from the Department". Registration is
required where drilling activity
includes "construction and reconstruction of water wells, the
establishment or repair of a connection through the well casing and the repair
of water wells including repairs which require the opening of the well
casing".
18DC) Test pits -
These pits are used to determine the level of the seasonal high water table and/or
the depth of impermeable substratum.
19DC) Thin wall
concrete sampling - Specialized drill tips allow for the analysis of
concrete.
20DC) Vane shear
testing - Vane shear testing is used in the determination of the un-drained
shear strength of the soil.
21DC) Well development
- The process of agitating, surging and pumping a well to remove fine grained particulate
sediment from the well and filter pack, stabilize the filter pack, and remedy
any damage to the screened water-bearing formation resulting from drilling activities.
