0 Not determined
A Artificial Any substance that is not part of an
aquatic environment and cannot be
described by the Sample Medium Codes
B-J or I-9
B Solids (street sweepings, Dry unconsolidated materials that are
etc.) collected from a street or paved area,
including the total array of materials
that are collected as part of a "clean
sweep," and cannot be described by Sample
Medium Codes C-J or 1-9.
C Animal tissue Any type of tissue that comprises
either whole or parts of insects, fish,
or other organisms living in an aquatic
environment, or warm bodied animals
that may or may not have been collected
from a water body.
D Plant tissue Any type of non-animal tissue that
comprises either whole or parts of
plants,aquatic or non-aquatic.
E Core material Consolidated or unconsolidated material
removed from a pipe or casing during a
drilling (coring) operation.
F Interstitial water Water occurring in the small openings,
spaces, and voids between particles of
unconsolidated materials in that portion
of the vadose water zone between the root
zone and the water table. The water is
held in place by entrapment, ionic
attraction, and capillary or adhesive
forces, rather than from upward pressure
components of saturation.
G Soil A wet or dry substance composed of
unconsolidated fine-grain rock fragments
(minerals) and organic material that has
been modified sufficiently by physical,
chemical, or biological processes to
support terrestrial plant growth.
H Bottom material A mixture of mineral and organic matter
that compose the top bed deposits
(usually the first few inches) under-
lying a body of water.
J Sludge An unconsolidated material, from an
anthropogenic source, covering the
ground or the bed of a water body,
usually originating as a result of
processes such as domestic or
industrial waste treatment.
K Soil Moisture Water occupying voids between loose
soil particles within the aerated root
zone. The water is held in place by
surface tension, capillary and
hydroscopic forces in opposition to the
pull of gravitational forces.
L-P Taxonomic data Biological data distinct from non-
taxonomic data which cannot be described
by Sample Medium Codes A-K or I-9.
(L) Phytoplanktonic
species composition
and enumeration
(M) Phytoplanktonic
species composition
(N) Periphytic species
composition
(O) Benthic invertebrates
species composition and
enumeration
(P) Periphytic diatoms
species composition and
enumeration
Q-Z Quality-assurance sample Blank samples taken to ensure that
environmental samples have not been
contaminated by the data-collection
process.
(Q) Artificial
(R) Surface water
(S) Ground water
(T) Wet deposition
(U) Bulk deposition
(V) Suspended sediment
(W) Bottom material
(X) Animal tissue
(Y) Plant tissue
(Z) Interstitial water
1 Suspended sediment Sediment carried in suspension by the
turbulent components of the fluid or by
the Brownian movement (a law of physics).
2 Leachate A solution obtained by passing a liquid
(usually aqueous) through an
unconsolidated solid medium, thereby
dissolving materials (from the solid
medium) which become a part of the
solution. It also contains those
precipitates that are the result of the
solution process and subsequent
chemical or biological reactions.
3 Dry deposition Solid, aerosol or gaseous materials
deposited from the atmosphere during dry
weather periods.
4 Landfill effluent A liquid material (usually water) that is
drained or pumped from a landfill. It
usually is a liquid that has percolated
through solid landfill material to become
a transport medium for materials
dissolved from the landfill.
5 Elutriation A process by which a mixture of an
unconsolidated solid medium (usually
soil) and a liquid medium (usually water)
has been agitated for a given period
of time to dissolve materials from the
solid. The solid/liquid mixture is
finally separated and the resulting
solution is analyzed for materials
dissolved duringthe elutriation process.
6 Ground water Water below the surface of the earth
contained in the saturated zone. It does
not include soil moisture or interstitial
water.
7 Wet deposition Water reaching the earth's surface
through precipitation as rain, snow,
sleet,hail or condensation of fog and
dew. The water may contain undissolved
particulate and gaseous materials
acquired from the atmosphere during
precipitation.
8 Bulk deposition A mixture of undesignated proportions
of wet and dry deposition sampled by
a continuously open container.
9 Surface water Water on the surface of the earth
stored or transported in rivers, streams,
estuaries, lakes, ponds, swamps, glaciers
or other aquatic areas. It also may refer
to water in urban drains and storm-
sewer systems.

Code Description Definition
-----------------------------------------------------------------------------------------------------------------
A Anode Anode is a hole used as an electrical anode. Include in this category wells used solely
to ground pipelines or electronic relays and other installations.
C Standby Standby emergency supply refers to a water-supply emergency source that is used only when
the principal supplier supply of water is unavailable.
D Drain Drainage refers to the drainage of surface water underground.
E Geothermal Geothermal well is a hole drilled for geothermal energy development.
G Seismic Seismic hole is one drilled for seismic exploration. If it has been converted to water
supply, it is used to withdraw water. A seismic hole used as an observation well should
be in the observation-well category.
H Heat reservoir Heat reservoir refers to a well in which a fluid is circulated in a closed system. Water
is neither added to, nor removed from, the aquifer.
M Mine Mine includes any tunnel, shaft, or other excavation constructed for the extraction
of minerals.
O Observation Observation well is a cased test-hole or well, drilled for either water-level or
water-quality observations. Do not use this category for an oil-test hole, or
water-supply well used only incidentally as an observation well.
P Oil or gas well Oil or gas well is any well or hole drilled in search of, or for production of, petroleum
or gas. It includes any oil or gas production well, dry hole, core hole, injection well
drilled for secondary recovery of oil, etc. An oil-test hole converted to a
water-supply well should be classified as withdrawal (W).
R Recharge Recharge site is a site constructed or converted for use in replenishing the aquifer.
An irrigation well used to return water to the aquifer during nonpumping periods is a
well for withdrawing water, not a drainage or recharge well. Use this category for
wells that are used to return water to the aquifer after use, such as those for
returning air-conditioning water.
S Repressurize Repressurize refers to pumping water into an aquifer in order to increase the pressure
in the aquifer for a specific purpose; for example, water flood purposes in oil fields.
T Test Test hole is an uncased hole (or one cased only temporarily) that was drilled for
water, or for geologic or hydrogeologic testing. It may be equipped temporarily with
a pump in order to make a pumping test, but if the well is destroyed after testing
is completed, it is still a test hole. A core hole drilled as a part of mining or
quarrying exploration work should be in this class.
U Unused An unused site is an abandoned water-supply site or one for which no use is contemplated.
At an abandoned farmstead, a well originally used for domestic purposes may be classed
as unused, even though it is equipped with a pump. Similarly, a stock well with a pump
may become unused when a pasture or corral is put into cultivation. An irrigation well
that is not equipped with a pump, nor used because the yield is too low or the water
is too mineralized, belongs in this class.
W Withdrawal of Withdrawal of water refers to a site where water is extracted. It includes a dewatering
well, if the dewatering is accomplished by pumping ground water.
X Waste disposal A waste-disposal site is one used to convey industrial waste, domestic sewage,
oil-field brine, mine drainage, radioactive waste, or other waste fluid into an under
ground zone. An oil-test or deep-water well converted to waste disposal should be in
this category.
Z Destroyed A destroyed site is one that is no longer in existence. The casing of most destroyed
wells will be pulled, but some may be plugged or filled. Do not use this category for
an abandoned site that merely is not in use.

Code Description Definition
----------------------------------------------------------------------------------------------------------------
A Air condition Air conditioning refers to water supply used solely or principally for heating or
cooling a building. Water used to cool industrial machinery belongs in the industrial
category, not in the air-conditioning category.
B Bottling Bottling refers to the storage of water in bottles and use of the water for potable
purposes (see Medicinal).
C Commercial Commercial use refers to use by a business establishment that does not fabricate or
produce a product. Filling stations and motels are examples of commercial establishments.
If some product is manufactured, assembled, remodeled, or otherwise fabricated, use of
water for that plant should be considered industrial, even though the water is not used
directly in the product or in the manufacturing of the product.
D Dewater Dewatering means the water is pumped for dewatering a construction or mining site,
or to lower the water table for agricultural purposes. In this respect, it differs from
a drainage well that is used to drain surface water underground. If the main purpose
for which the water is withdrawn is to provide drainage, dewatering should be indicated
even though the water may be discharged into an irrigation ditch and subsequently used
to irrigate land.
E Power Power generation refers to use of water for generation of any type of power.
F Fire Fire protection refers to the principal use of the water and should be indicated if the
site was constructed principally for this purpose, even though the water may be used at
times to supplement an industrial or defense supply, to irrigate a golf course, fill a
swimming pool, or for other use.
H Domestic Domestic use is water used to supply household needs, principally for drinking, cooking,
washing, and sanitary purposes, but including watering a lawn and caring for a few pets.
Most domestic wells will be at suburban or farm homes, but wells supplying small
quantities of water for domestic purposes for one-classroom schools, turnpike gates,
and similar installations, should be in the domestic category.
I Irrigation Irrigation refers to the use of water to irrigate cultivated plants. Most irrigation
sites will supply water for farm crops, but the category should include wells used to
water the grounds of schools, industrial plants, or cemeteries, if more than a small
amount of water is pumped and that is the sole use of the water.
J Industrial Industrial cooling refers to a water supply used solely for industrial cooling.
K Mining Mining refers to a water supply used solely for mining purposes.
M Medicinal Medicinal refers to water purported to have therapeutic value. Water may be used for
bathing and/or drinking. If use of water is mainly because of its claimed therapeutic
value, use this category even though the water is bottled.
N Industrial Industrial use is within a plant that manufactures or fabricates a product. The water
may or may not be incorporated into the product being manufactured. Industrial water
may be used to cool machinery, to provide sanitary facilities for employees, to
air-condition the plant, and to irrigate the ground at the plant.
P Public supply Public Supply use is water that is pumped and distributed to several homes. Such
supplies may be owned by a municipality or community, a water district, or a private
concern. In most States, public supplies are regulated by departments of health which
enforce minimum safety and sanitary requirements. If the system supplies five or more
homes, it should be considered a public supply, as four or less classify use as domestic.
Water supplies for trailer or summer camps with five or more living units should be in
this category, but motels and hotels are classified as commercial. Most public supply
systems also furnish water for a variety of other uses, such as industrial,
institutional, and commercial.
Q Aquaculture Aquaculture refers to a water supply used solely for aquaculture, such as fish farms.
R Recreation Recreation refers to water discharged into pools (or channels which are dammed
downstream to form pools), for swimming, boating, fishing, ice rinks, and other
recreational uses.
S Stock Stock Supply refers to the watering of livestock.
T Institutional Institutional refers to water used in the maintenance and operation of institutions
such as large schools, universities, hospitals, rest homes, or similar installations.
Owners of institutions may be individuals, corporations, churches, or governmental units.
U Unused Unused means water is not being removed from the site for one of the purposes described
above. A test hole, oil or gas well, recharge, drainage, observation, or waste-disposal
well will be in this category. Do not use this classification for an irrigation,
domestic, stock, or other well during "off season" or temporary periods of nonuse.
The use of water from a newly constructed site should be considered as the use for
which it is intended even though it may not yet be in use when inventoried.
Y Desalination Desalination refers to water used in a desalting process whereby dissolved solids
are removed to make water potable or suitable for other uses. Enter the type of use
of the desalinated water in the next column, "Secondary Water Use".
Z Other Other refers to miscellaneous uses not included in the listed categories.
