Ohio Admin. Code 3745-81-76 - Water source designation
(A)
Source water
which is open to the atmosphere or subject to surface runoff is designated as
surface water. Surface water sources include streams, rivers, ponds, lakes,
reservoirs, springs, roof collection and impoundments.
(B)
Source water
which is obtained from a well is designated as ground water unless the director
designates the source as surface water.
(C)
The director may
designate a well as surface water based on information available in Ohio
environmental protection agency files about the water source and the water
produced from the source, information from on-site sanitary or geological
surveys, information supplied by the public water system upon a request from
the director, any additional information which becomes available, and the
guidelines outlined in the following paragraphs. A public water system shall
provide information requested by the director within six months of receipt of a
written request. Information requested for each water source may concern water
quality, well construction and location, geological information, particulate
analysis, Cryptosporidium analysis, Giardia lamblia analysis, E.coli analysis,
ground water source samples related to rules
3745-81-41
to
3745-81-43
of the Administrative Code, and other information related to designation of the
water source. A well may be designated as surface water if it meets any of the
following criteria:
(1)
The well does not meet all of the requirements for
wells in Chapter 3745-9 of the Administrative Code;
(2)
The well obtains
water from a site at which rapid pathways or compromised hydrogeologic barriers
have been identified; or
(3)
If required by the director, analysis shows the annual
mean E. coli concentration is greater than or equal to ten E. coli per one
hundred milliliters.
(D)
The director
shall at a minimum consider the following criteria in making a surface water
designation for a well:
(1)
A well does not meet all of the requirements for wells
in Chapter 3745-9 of the Administrative Code;
(2)
A well obtains
water from a site at which rapid pathways or compromised hydrogeologic barriers
have been identified;
(3)
A well is cased less than fifteen feet in
depth;
(4)
A vertical well where the sum of the casing depth plus
the horizontal distance to a normal surface water pool is less than forty
feet;
(5)
A horizontal collector well lateral or infiltration
gallery collector pipe less than twenty-five feet below the ground
surface;
(6)
A horizontal collector well where the sum of the depth
of any lateral below grade or stream, lake, reservoir bed plus the horizontal
distance measured at the end of any lateral to a normal surface water pool is
less than fifty feet; or
(7)
An annual mean E. coli concentration equal to or more
than ten E.coli colonies per one hundred milliliters based on monitoring of the
source.
(E)
Assessment source water monitoring as described in
paragraph (B) of rule
3745-81-42
of the Administrative Code shall be completed for the source when one of the
following conditions exist:
(1)
A well is cased between fifteen and twenty-five feet
in depth;
(2)
A well is located less than fifty feet from a normal
water surface;
(3)
Infiltration galleries, recharge lagoons or other
basins constructed to increase the rate of infiltration are
used;
(4)
A horizontal collector which meets the criteria in
paragraph (D)(5) or (D)(6) of this rule;
(5)
Any potential
for surface water contamination exists within the approved isolation radius,
including but not limited to improperly abandoned wells, leach beds, sanitary
or combined sewers, or septic tanks;
(6)
Gravity sewers
built to water line standards and pressure tested are closer than one third the
usually required isolation or if there are manholes on these pressure tested
lines within the isolation area;
(7)
A well is
located in bedrock where the bedrock may be directly connected to surface water
such as through fractures or solution features;
(8)
A waterborne
disease outbreak has been associated with the well; or
(9)
Other surface
water contamination hazards exist.
(F)
Designation of a
public water system's water sources as including surface water shall bring this
public water system under the requirements of rules
3745-81-64
to
3745-81-69
and
3745-81-71
to
3745-81-75
of the Administrative Code.
(G)
Designation of a
public water system's water sources as including ground water shall bring this
public water system under the requirements of rules
3745-81-41
to
3745-81-45
of the Administrative Code, unless all of the ground water is combined with
surface water prior to treatment under rule
3745-81-71
of the Administrative Code.
(H)
The director may
redesignate a water source as surface water or as ground water at any time that
additional information indicates that redesignation is appropriate.
