If any well(s) are located less than 1.000 feet awayfrom the new well, the driller shall measure the waterlevels of those well(s) during the long-term andsubsequent recovery tests at the same time intervals as thewell is being pumped.

(1) For step-drawdown tests, the pump shall beinitially operated at the rate of 50 gpm. The pumpingrate will then be increased by 50 gpm increments atone hour intervals until the well has been tested atdesign capacity or maximum pumping rate,whichever is lower. The test duration shall not exceed12 hours unless otherwise specified by theAdministrator. During the test, the driller shall recordthe time, water level in the pumped well and allobservation wells, and discharge at 15-minutesintervals. When the test is completed and the pumpstopped, the driller shall measure water level recoveryin the well and observation wells as directed undersub-section (3) below until the water level has fullyrecovered to the original static water level.

(2) The long-term, continuous, constant-rate, time-drawdown tests shall commence after the water levelin the pumped well has recovered from the step-drawdown test. The rate of pumping shall be equal to100 percent design capacity or as determined by theAdministrator. The driller shall insure that thepumping rate selected remains within the allowablevariance of plus or minus 10 percent throughout the


APPENDIX A -


test. The test duration is anticipated to be less than 24hours, but the driller shall run the test for a period oftime as directed by the Administrator.

The water levels shall be measured by the drillerin the well being pumped, all observation wells, andsprings or ponds hydraulically connected to theaquifer at the following time intervals or as directedby the Administrator.

0 to 5 minutes - once every 0 seconds

5 to 10 minutes - once every minute

10 to 30 minutes - once every two minutes

30 to 90 minutes - once every ten minutes

90 to completion - once every hour

During the long-term tests, changes in waterquality, particularly chloride concentrations, areextremely important. The driller shall take watersamples at the following intervals or as directed by theAdministrator, for analysis of chloride content.

One sample after two minutes of pumping

Once every hour for the first 10 hours

Once every two hours for the remainder of thetest.

(3) As soon as the pump is turned off at thecompletion of the time-drawdown test, the timerecovery test shall begin. The driller shall take waterlevel measurements in the well being pumped and allobservation wells, and springs or ponds at thefollowing time intervals or as directed by theAdministrator.

0 to 5 minutes - once every 30 seconds

5 to 20 minutes - every minute (or until fullrecovery to original static water level)


APPENDIX A -


20 minutes to full recovery every five minutes

(4) If there is any interruption in conducting thistest, the driller shall re-do the test after the water levelhas fully recovered.

(5) The driller shall plot all test data on semi-loggraph paper with drawdown (recovery) indicated onthe arithmetic axis and time (in minutes) on thelogarithmic axis.

(6) The driller shall not consider the yield at thebeginning of the test if the water level is dropping. Forestimating the actual flow of water, the yield shall bemeasured after the water level in the well hasstabilized. The estimated yield shall be determined bythe average output when drawdown has ceased andwhen the water table has been stable for at least fourcontinuous hours. The time intervals required for thewater level to return to its original level shall begin tobe recorded immediately after pumping has ceased.

§7117. Disinfection and Other SanitaryRequirements. (a) All newly constructed wells or existingwells subjected to any repair work shall be disinfectedbefore being placed in service. A chlorine solution ofapproximately 100 mg/l of available chlorine in the wellwater is normally adequate. The solution shall beintroduced into the well in such a manner that all surfacesabove the static level will be completely flushed with thesolution. The well contents should then be agitated touniformly distribute the chlorine throughout the well. Thechlorine solution shall remain in the well for not less than24 hours. The chlorine residual should be monitored toinsure adequate concentration. Before providing water forconsumptive use, the well shall be flushed until all tracesof chlorine have been removed. After flushing the residualchlorine from the well, a water sample shall be collectedfor bacterial analysis. If the coliform bacteria test is positive(i.e., one or more counts per 100 ml), the well shall bedisinfected again as prescribed above. Water samples shallthen be placed into operation until the well has beenadequately disinfected as demonstrated by testing.

(b) Gravel. Gravel used in gravel-packed wells shallcome from clean sources and should be thoroughlywashed and disinfected by hypochlorite treatment beforebeing placed in the well. Gravel purchased from a suppliershould be washed free of silt, and other foreign materialsprior to delivery to the well site. Crushed rock shall not beused.

(c) Drilling Fluid. Only fresh water shall be used indrilling fluids whether employed alone or in combinationwith drilling additives. Only high grade clays or


APPENDIX A -


commercial chemicals, approved by the Administrator,shall be used in the make-up of any drilling fluid. Drillingfluid with a mixture of water and unprocessed mud, clay,or other material will not be permitted. Drilling fluid shallnot impart any toxic substances to the water or promotebacterial contamination. Drilling fluid ejected from thewell during drilling operation must be contained on-site ordisposed off as directed by the Administrator.

(d) The premises, materials, tools and drillingequipment shall be maintained so as to minimizecontamination of the underground water during thedrilling operation.

(e) Disinfection of Non-flowing Wells.

(1) Method A. Where practical, the standard-concentration chlorine solution used to disinfect thewell should be prepared in the surface in containershaving a volume equal to at least twice the volume ofwater contained in the well. This prepared solutionshould then be rapidly discharged into the well, carebeing taken to flush the walls above the water level.

(2) Method B. Instead of preparing the standard-concentration chlorine Solution in containers, a stockchlorine solution of 15,000 mg/l could be added to acontinuous flow of water into the well to provide thestandard-chlorine concentration. Either of the abovemethods will carry the chlorinated water into thevoids of the water-bearing formation and shouldprovide effective treatment if the chlorinated water isapplied rapidly enough to reach all formationspenetrated by the well or is introduced at differentlevels in it.

(3) Method C. If methods A and B are notpractical, stock solution may be added to the well,preferably at different levels, to provide the standardconcentration in the, water contained in the well. Thewell should then be agitated with a bit, bailer, or testpump to spread the chlorine solution throughout thewater.

(4) Method D. Instead of using liquid chlorinesolutions, a perforated pipe container capped at both


APPENDIX A -


ends, containing hypochlorite tablets may be movedup and down in the wall by means of a weightedcable. Sufficient compound should be applied toprovide the standard concentration.

(f) Disinfection of equipment and material used inwell.

(1) If the well is disinfected prior to the insertionof the test pump all exterior parts of the test pumpscoming in contact with the water must be cleaned,wetted, and dusted with a powdered chlorinecompound. If possible, at the start of the operation ofthe pump, the pump discharge be so regulated thatsome of the chlorinated water maybe returned to thewell.

(g) Chlorine Solution. A stock solution of chlorinemay be prepared by dissolving fresh chlorinated lime,hypochlorite tablets, or other chlorine compounds in waterin the proportion of 4 oz (113.4 g) of available chlorine to 1gal. (3.79 L) of water. This gives a chlorine concentration of30,000 mg/l or 3.0 percent, by weight. To obtain an appliedstandard concentration of 100 mg/1, 1 gallon (3.79 L) ofstock solution is used to treat 300 gallons (1136 L) of water.

Table 1 shows the number of ounces of chlorinecompounds of a given available chlorine content (generallymarked on the outside of the can or package) required forthe effective disinfection of the well can be computed bythe use of Table I together with Table 2, showing thecontents in gallons per foot of wells of various diameters.Volume of water for various size wells is shown in Table 3.

sealing when certain conditions have been found to exist asestablished through inspection by the Administrator.

(1) When the well is wholly situated inunconsolidated material in an unconfinedgroundwater zone. If the groundwater is within fifty(50) feet of the surface, the upper twenty (20) feet shallbe sealed with impervious material and the remainderof the well shall be filled with clay, sand, or othersuitable inorganic material.

(2) Well penetrating several aquifers orformations. In all cases the upper twenty (20) feet ofthe well shall be sealed with impervious material.

In areas where the interchange of water betweenaquifers will result in a deterioration of the quality ofwater in one or more aquifers, or will result in a loss ofartisan pressure, the well shall be filled and sealed soas to prevent such interchange, and or otherformations where impervious sealing material is notrequired. Impervious material must be placedopposite confining formations for a sufficient verticaldistance (but no less than 10 feet) in either direction, orin the case of “bottom water", in the upward direction.
