Step 1. Measure The Dimensions Of The Well. Measurements Must Be Taken Of The Well Diameter, Depth And Water Level. Accurate Measurements (Not Estimates) Will Allow The Correct Calculation Of The Total Well Volume And The Volume Of Water In The Well. This Information Is Needed To Determine The Amount Of Materials Needed For Plugging . Remember That Volume Calculations Depend On The Shape Of The Well. Most Wells Are Cylindrical; However, Some Have Other Shapes Tha T Must Be Considered For Accurate Calculation Of Volume. Step 2. Remove All Obstructing Materials From The Well. Making Sure That Fill Materials Do Not Slump Or Settle Is Critical; Therefore, Obstructions That May Cause Incomplete Filling Of The Voids Must Be Re Moved. Remove The Pump, Rods, Pipes And Any Other Equipment From The Well. Floating Debris, Such As Wood Staves, Also Should Be Remo Ved. One Method Used To Accomplish Debris Removal Is Flushing. If Water Is Pumped Into The Well, Floating Debris Will Move To The To P As The Well Fills With Water. Flushing May Not Be Possible With Larger Diameter Wells Due To The Volume Of Water Required. In Any Event, As Much Debris As Possible Must Be Removed From The Well Before Plugging. Initial Well-Plugging Steps Include Accurate Measur Ement Of The Well Dimensions And Removal Of All Obstructions. Step 3. Disinfect The Well By Adding Household Bleach. All Wells Con Taining Standing Water Must Be Disinfected To Kill Existing Microorganisms. This Can Be Accomplished By Adding Chlorine Bleach At Th E Rate Of 1 Gallon Of Bleach For Every 500 Gallons Of Water And Is Equivalent To A #Shock# Chlorination Concentration Of 100 Parts P Er Million Of Chlorine. The Chlorination Process Ensures That Disease-Causing Microorganisms Are Not Sealed In The Aquifer. The Chlo Rination Procedure Disinfects The Well So That Disease-Causing Microorganisms Are Not Sealed In The Aquifer After The Well Is Plugge D. Step 4. Fill The Well With Plugging Materials. Plugging Always Starts From The Bottom Of The Well. The Exact Procedure For Plugging Will Depend On Well Construction, Depth, Diameter, Aquifer Type, Availability Of Materials And The Level Of Protection Req Uired. Step 5. Remove The Upper 3 Feet Of The Well Casing. This Step Never Should Be Done Before The Fill Material Is Within 3 Fee T Of The Surface. Upper Casing Removal Is Particularly Important If The Abandoned Well Site Is Farmed. Removing The Upper 3 Feet Of Casing Eliminates Potential Damage To Tillage Equipment. Step 6. Fill The Final 3 Feet With Topsoil And Mound. Shaping The Site Is Necessary To Prevent Ponding Of Water Over The Plugged Well. Topsoil Should Be Packed Into The Well And Mounded Up To 1½ Feet Over The Site. Mounding Will Help Direct Surface Water Away From The Site And Also Will Help Absorb Any Settling Of Fill Materials.
