3745-9-04 Well siting.

(A) A well shall be located in accordance with these requirements.

(1) A well, other than a well for the removal of contaminants, shall be located the maximum practical distance from potential or known sources of contamination and only where it can be maintained in a sanitary condition.

(2) A well, other than a well for the removal of contaminants, shall be located only where surface and subsurface conditions will not allow contaminants to be conducted into the well.

(3) A public water system shall own all the land or obtain an easement or lease of the sanitary isolation radius of a public water system well, and such easement or lease shall be recorded with the county recorder.

[Comment: the director recommends ownership by the public water system of land at least within the sanitary isolation radius.]

(4) The sanitary isolation radius is determined from the estimated average daily water demand of the public water system well. Estimated average daily water demand may be determined by the director from the pumping design rate of the well.

See Table at

http://www.registerofohio.state.oh.us/pdfs/3745/0/9/3745-9-04_PH_FF_A_RU_20090803_0818.pdf

(5) The director may specify greater sanitary isolation requirements for a public water system well where conditions are determined to exist such that the sanitary isolation radius set forth in paragraph (A)(4) of this rule is insufficient to protect the public health and the public water system from contaminants.

(6) Potential sources of contamination shall not be constructed or placed within the sanitary isolation radius of a public water system well.

(7) A well shall be adequately protected from physical damage.

(8) A public water system well shall be located at least:

(a) Fifty feet from streams and lakes,

(b) Three hundred feet from a human or animal waste management facility,

(c) Three hundred feet from a land application area, stockpile, storage or staging area,

(d) One hundred feet from a land application area field if the waste is injected or three hundred feet if the waste is surface applied but in no case within the sanitary isolation radius of the well,

(e) Three hundred feet from a soil absorption system handling more than ten thousand gallons per day,

(f) One thousand feet from a landfill or monofill, and

(g) Five hundred feet from a construction and demolition debris facility.

(9) A well shall not be located either within ten feet of or within the foundation of any building, except within a pumphouse.

(10) A well shall not be located in a floodway without prior acceptance of the director.

(11) A public water system well used by a community or nontransient noncommunity public water system shall be located such that the following are not located within the proposed well's inner management zone:

(a) Human or animal waste management facility, except a well used by the facility,

(b) Soil absorption system handling more than ten thousand gallons per day in an area where the Ohio environmental protection agency has determined the aquifer has a high susceptibility to contamination, and

(c) Land application stockpile, storage or staging area where the Ohio environmental protection agency has determined the aquifer has a high susceptibility to contamination.

(12) A public water system well shall be sited such that no landfill or monofill is located within the proposed well's drinking water source protection area.

(13) In instances where a proposed well cannot be feasibly located such that the conditions specified in paragraphs (A)(8), (A)(11) and (A)(12) of this rule are met, the director may grant a variance in accordance with paragraph (E) of rule 3745-9-02 of the Administrative Code. The applicant must make an adequate demonstration that documents the site hydrogeology, engineering controls, or other physical barriers are sufficient to minimize the risk of contaminantion being drawn into the well.

(14) The requirements set forth in paragraphs (A)(8), (A)(11) and (A)(12) of this rule become effective January 1, 2010.

(15) The director may require a hydrogeologic investigation to select the location of a well to ensure that contaminants will not be drawn into the well and that a sufficient quantity of ground water exists for the intended purpose. These investigations may be required where, without limitation, one of these well siting circumstances exist: potential or known contamination; hydrogeologic setting that may allow transport of contaminants; or initial development of a community well field. The investigation shall be conducted by a hydrogeologist. A hydrogeological investigation is a study of the subsurface and geologic conditions. Information shall be collected, without limitation, about the type and thickness of geologic materials, the occurrence of ground water, how it flows in pore spaces and fractures, and the quantity and quality of the ground water.

[Comment: An owner or operator of a public water system that proposes to locate a well in a one hundred year floodplain or floodway must also obtain approval from state or local floodplain management agencies as appropriate.]

(B) A well shall be located so it is accessible for cleaning, treatment, repair, alteration, testing, and such other actions as may be necessary.

(1) Where consolidated formations are encountered within twenty-five feet of the ground surface, an oversized borehole shall be drilled and the annular space shall be filled with cement grout or bentonite grout by pressure grouting.

(2) A well completed where multiple aquifers are present shall have the casing extend through aquifers that are not contributing to the water supply of the well. The annular space contiguous to aquifers that are not contributing to the water supply of the well shall be filled with either cement grout or bentonite grout by pressure grouting.

(3) A well completed in confined aquifers shall have the casing extend through the confining layer to the top of the aquifer. The annular space contiguous to the confining formation shall be filled with either cement grout or bentonite grout by pressure grouting. Filter packs and formation stabilizers shall not extend significantly into a confining formation or allow interconnection of two separate aquifers along the annular space.

(4) A well completed in aquifers with hydrostatic heads greater than the land surface elevation shall have casing and grout installed to protect the aquifer, prevent erosion of the overlying geologic materials, and confine the flow to within the casing and shall be constructed according to these procedures.

(a) If the anticipated flow at the ground surface is not excessive, after the borehole is drilled, and the casing set, the water in the casing may be pumped to lower the water level in the casing and the annular space. The annular space shall then be filled with cement grout by pressure grouting. The density of cement grout shall be sufficient to control flow in the annular space, but no less than that required by rule 3745-9-07 of the Administrative Code.

(b) If the anticipated flow at the ground surface is excessive, an upper enlarged borehole shall be drilled partially into the confining formation. The upper enlarged borehole shall be at least four inches in diameter larger than the nominal diameter of the outer well casing. The annular space between the upper enlarged borehole and outer well casing shall be filled with cement grout by pressure grouting. The outer casing may be left as permanent casing once the well is completed or may be removed. Where outer casing is not removed, the casing shall be withdrawn at least five feet to insure grout contact with the formation.

(i) If the confined aquifer is consolidated, a smaller diameter borehole shall be drilled through the upper enlarged borehole, the inner casing shall be firmly seated into the bedrock, and the remaining annular space shall be filled with cement grout by pressure grouting. The density of cement grout shall be sufficient to control flow in the annular space, but no less than that required by rule 3745-9-07 of the Administrative Code.

(ii) If the confined aquifer is unconsolidated, a smaller diameter borehole shall be drilled through the upper enlarged borehole, with casing and a screen installed into the confined aquifer. The well shall be double cased, and the remaining annular space filled with cement grout by pressure grouting. The density of cement grout shall be sufficient to control flow in the annular space, but no less than that required by rule 3745-9-07 of the Administrative Code.

(5) A well completed in a cavernous formation or mine shall be constructed according to these requirements.

(a) A cavernous formation or mine that is not being used as a source of water shall have casing installed through the formation or mine.

(i) If a cavernous formation or mine is greater than twenty-five feet below ground surface, then the formation or mine shall be filled with cuttings, clean gravel or grout. Packers or shale baskets shall be installed at the top and bottom of the formation or mine. The annular space shall then be filled with either cement grout or bentonite grout by pressure grouting.

(ii) If a cavernous formation or mine is less than twenty-five feet below ground surface, casing shall be installed in an enlarged borehole and the annular space shall be filled with a cement grout containing additives that promote bridging of the cavernous formation or mine by pressure grouting to a depth of at least five feet beyond the formation or mine.

(b) If a cavernous formation or mine will be the source of water supply, then a packer or shale basket shall be installed at the top of the formation or mine and the annular space shall be filled with either cement grout or bentonite grout by pressure grouting.

(6) A well encountering brine producing formations shall be constructed according to these procedures. Brine producing formations that are encountered during drilling shall have casing installed through the brine producing formation. The annular space contiguous to the brine producing formation shall be filled with either cement grout or bentonite grout by pressure grouting or the well shall be sealed to an elevation higher than the top of the brine producing formation. Grout shall be used that is not adversely affected by the brine water for sealing the well or annular space.

(7) Except when a well is completed in the upper-most weathered portion of a consolidated formation, a well completed in a consolidated formation shall have the casing extend into the formation so that the well casing will not settle or shift and it will have a proper annular seal.

3745-9-09 Well development and pumping test.

(A) A public water system well shall be developed upon completion until turbidity or sand content in the well is minimal and until the maximum specific capacity is obtained to remove the native silts and clays, drilling mud or finer fraction of the filter pack.

(1) Mechanical development shall be performed so as not to cause damage to the components of the well. Mechanical development techniques include: mechanical surging; air surging or air lifting; overpumping and backwashing; high velocity jetting; bailing; and hydrofracturing.

(2) With prior consultation with the district office, chemical development procedures may be used in conjunction with mechanical procedures. Chemical development techniques include using an acid or dispersant that has standard ANSI/NSF 60 certification. The director may require submission of chemical development procedures with specifications for the method, equipment, chemicals, and testing for residual chemicals.

(a) Dispersant may be used to disaggregate clay particles to enhance removal. Dispersant shall be immediately flushed from the well and aquifer to prevent bacterial growth in the aquifer.

(b) Dispersant shall be premixed and used according to the manufacturer's recommendations.

(c) Acid shall be used according to the manufacturer's recommendations. Proper pH shall be maintained in the borehole to ensure the effective action of the acid.

(B) Upon completion of development of the public water system well, a pumping or aquifer test shall be conducted to determine the sustainable yield and drawdown of the well. The flow rate shall be measured using an orifice weir with manometer, or equivalent method acceptable to the director.

(1) The pumping test classification is determined from the estimated average daily water demand of the well and type of water system. Estimated average daily water demand may be determined by the director from the design pumping rate of the well. With prior consultation, the director may accept an alternative constant rate pumping test that is conducted under the supervision of a hydrogeologist or person with demonstrated competency in performing pumping or aquifer tests.

Classification Estimated Average Daily Demand of the Well (gallons per day)
Low use 0 to 10000
Medium use 10001 to 100000
High use greater than 100000

An acceptable pumping test for low, medium, or high use classifications is:

(a) For low use community water system wells and low or medium use noncommunity water system wells, the pumping test shall be conducted at a constant rate for a period of at least normal operation either at the peak hourly demand, or at least 1.5 times the pump design rate if the well cannot sustain peak hourly flow;

(b) For medium use community water system wells, the pumping test shall be conducted at a constant rate for at least twenty-four hours either at the peak hourly demand, or at least 1.5 times the pump design rate if the well cannot sustain peak hourly flow;

(c) For all high use wells, an aquifer test shall be conducted. A step-drawdown test shall be conducted with at least three progressively increasing pumping rates. Then, a constant rate pumping test shall be conducted at least twenty-four hours for at least 1.5 times the pump design rate.

When hydrogeologic conditions or physical constraints are such that it is not possible to achieve a sustainable yield of the well at 1.5 times the pump design rate, a constant rate pumping test may be conducted at a lower pumping test rate if the following criteria are met:

(i) The constant rate pumping test is conducted at no less than 1.2 times the pump design rate; and

(ii) A demonstration is provided documenting the hydrogeologic conditions and well construction design criteria that supports the lower pumping test rate.

[Comment: It is recommended that a person with demonstrated competency perform the respective pumping test or aquifer test.]

(2) The pumping/aquifer test report shall include, without limitation:

(a) Date and times of starting through ending pumping test;

(b) Pumping rate and pump setting depth;

(c) Water level measurements from the well of the static water level and drawdown to the nearest 0.1 foot, as measured from an identified datum;

(i) Water level measurements shall be at these time intervals:

Time After Pump Test Started (minute) Time Interval Between Measurements(minute)
0-15 1
15-60 5
60-120 10
120-180 20
180-300 30
300-1440 60

(ii) An aquifer test shall include water level measurements from observation or surrounding wells.

(d) Specific capacity;

(e) Graphic evaluation on semilogarithmic graph paper by plotting the drawdown measurements on the arithmetic scale and time on the logarithmic scale;

(f) Water level measurements immediately after termination of the constant rate pump test for a period of time until the water level is essentially unchanged at time intervals of five minutes for the first hour and every thirty minutes thereafter.

(C) Samples shall be collected and analyzed from a public water system well for contaminants at the conclusion of the pumping test performed accordance with paragraph (B) of this rule.

(1) A public water system well shall be sampled and analyzed for the contaminants that are listed in the appendix to this rule, "Required Analyses for Wells." The director may reduce or add to the contaminants that are listed in the appendix to this rule because of well siting, well construction, treatment, promulgated drinking water standards, or other criteria to assess whether the ground water is acceptable for human consumption.

(2) Samples that are collected from a public water system well in accordance to this rule shall be analyzed in a laboratory certified to analyze drinking water for contaminants in accordance with Chapter 3745-89 of the Administrative Code. The analytical methods shall be the same as required by the entry point to the distribution system monitoring in accordance with rule 3745-81-27 of the Administrative Code and shall include all the volatile organic and synthetic organic analytes that are quantified by the laboratory for the organic analytical method.
