SECTION 33 20 01 WATER WELL CLEANING AND REDEVELOPMENT
3.02 Cleaning Procedures - This section outlines the work required for both well sites and indicates the appropriate
chemical quantities specific to each well.
A. For Both Wells: Pre-Cleaning Mechanical Brushing. Mechanical brushing from the top of the well
to the bottom using a stiff nylon bristle brush to loosen debris and scale. Well cleaning brush shall
be manufactured specifically for the use on water wells and for this purpose.
B. For Both Wells: Air lifting/pumping. Air lift or pump the well to remove loosened debris and
sediment from the bottom of the well. Water shall run generally free of debris and color prior to adding
chemicals.
C. Acid and Biodispersant Treatment. Chemical quantities are noted for each well.
1. For Well No. 2: The standing water volume in Well No. 2 is about 710 gallons. The total
treatment volume for acid treatment will be about 1.5 times the standing volume of water - this
is roughly equal to 1070 gallons. Chemical quantities to use to achieve the target concentrations
are as follows;
a. 72 gallons NW-120 Phosphoric Acid (75%) to achieve 8% phosphoric acid in the treatment
solution.
b. 18 gallons NW-310 Biodispersant to achieve 2% biodispersant in the treatment solution.
c. 1070 gallons of Potable Water
2. For Well No. 4: The standing water volume in Well No. 4 is about 520 gallons. The total
treatment volume for acid treatment will be about 1.5 times the standing volume of water - this
is roughly equal to 780 gallons. Chemical quantities to use to achieve the target concentrations
are as follows;
a. 53 gallons NW-120 Phosphoric Acid (75%) to achieve 8% phosphoric acid in the treatment
solution.
b. 13 gallons NW-310 Biodispersant to achieve 2% biodispersant in the treatment solution.
c. 780 gallons of Potable Water
3. For Both Wells: Blend chemicals in an adequately-sized poly tank in the following order; potable
water first, then phosphoric acid, then biodispersant. Mix lightly. Introduce chemicals throughout
the standing water column via tremie pipe or similar mechanism starting from the bottom.
4. For Both Wells: Surge the well using a swab block or brush specifically manufactured for the
use in water wells. Surging shall be focused on the screened interval. Assume a surging time of
6 hours. Allow the well to rest for a period of at least 12 hours after surging is complete. Maintain
a pH of 3.0 or lower throughout the surging procedure - add additional phosphoric acid
to adjust the pH down if necessary.
5. For Both Wells: Pump the well to a storage tank to purge loosened and dissolved debris from
the well. Pump until the pH has returned to normal (about 7-7.5), and the conductivity has
returned to normal (about 900 S/cm) and the water is free of turbidity and color.
6. For Both Wells: Neutralize the purged water with an alkaline product as sodium hydroxide,
sodium bicarbonate, or potassium hydroxide. Once neutralized to a pH of about 7 and solids
have settled, dispose of the solution according to local and state guidelines.
D. Phase I Disinfection. Chemical quantities are noted for each well.
1. For Well No. 2: Prepare a disinfection solution of 200-ppm chlorine for two (2) times the standing
well volume of the well - this is equal to about 1420 gallons of solution. Chemical quantities to
use to achieve the target concentration are as follows;
a. 2.4 gallons 12% sodium hypochlorite
b. 1420 gallons of potable water
2. For Well No. 4: Prepare a disinfection solution of 200-ppm chlorine for two (2) times the standing
well volume of the well - this is equal to about 1040 gallons of solution. Chemical quantities to
use to achieve the target concentration are as follows;
a. 1.7 gallons 12% sodium hypochlorite
b. 1040 gallons of potable water

SECTION 33 20 01 WATER WELL CLEANING AND REDEVELOPMENT
3. For Both Wells: Blend chemicals in an adequately-sized poly tank adding additional sodium
hypochlorite if necessary to achieve a 200 ppm chlorine solution. Introduce chemicals
throughout the standing water column via tremie pipe or similar mechanism starting from the
bottom.
4. For Both Wells: Surge the well lightly using a swab block or brush for at least six (6) hours to
allow sufficient contact time within and outside the well screen. Maintain a chlorine concentration
of 200 ppm throughout this surging procedure - add sodium hypochlorite if necessary.
5. For Both Wells: Pump the well to a storage tank to purge loosened and dissolved debris from
the well until a minor residual is present - about 50 ppm chlorine and conductivity has returned
to normal (about 900 S/cm) and the water is free of turbidity and color.
6. For Both Wells: Neutralize the purged water with sodium thiosulfate - utilize one (1) pound
sodium thiosulfate for every 1000 gallons of 150 ppm purge water. Once the chlorine has been
neutralized and solids have settled, dispose the solution according to local and state guidelines.
E. Phase II Disinfection.
1. For Well No. 2: Prepare a pH-adjusted disinfection solution of 300-ppm chlorine in the pH range
of 6.5-7 for three (3) times the standing well volume of the well - this is equal to about 2130
gallons of solution. Chemical quantities to use to achieve the target concentration are as follows;
a. 5.3 gallons 12% sodium hypochlorite
b. 11 gallons of NW-410 Chlorine Enhancer
c. 2130 gallons of potable water for blending
2. For Well No. 4: Prepare a pH-adjusted disinfection solution of 300-ppm chlorine in the pH range
of 6.5-7 for three (3) times the standing well volume of the well - this is equal to about 1560
gallons of solution. Chemical quantities to use to achieve the target concentration are as follows;
a. 4 gallons 12% sodium hypochlorite
b. 8 gallons of NW-410 Chlorine Enhancer
c. 1560 gallons of potable water for blending
3. For Both Wells: Blend chemicals in an adequately-sized poly tank starting with the chlorine
enhancer. Add additional sodium hypochlorite if necessary to achieve a 300 ppm chlorine
solution. Introduce chemicals throughout the standing water column via tremie pipe or similar
mechanism starting from the bottom.
4. For Both Wells: Surge the well lightly using a swab block or brush for at least six (6) hours to
allow sufficient contact time within and outside the well screen. Maintain a chlorine concentration
of 300 ppm throughout this surging procedure - add sodium hypochlorite if necessary.
5. For Both Wells: Pump the well to a storage tank to purge loosened and dissolved debris from
the well until a minor residual is present - about 50 ppm chlorine and conductivity has returned
to normal (about 900 S/cm) and the water is free of turbidity and color.
6. For Both Wells: Neutralize the purged water with sodium thiosulfate - utilize one (1) pound
sodium thiosulfate for every 1000 gallons of 150 ppm purge water. Once the chlorine has been
neutralized and solids have settled, dispose the solution according to local and state guidelines.
F. Pump Disinfection - Both Wells: Before placing associated equipment back into the well, disinfect
all outside surfaces using a handheld spray rig with a 100-ppm sodium hypochlorite solution - use
3.2 mL (0.11 fluid oz.) 12% sodium hypochlorite for each 1-gallon of potable water.
G. Post-Cleaning Well Performance Test Pumping - Both Wells:. This test pumping is intended to
establish the well performance after the cleaning procedure. The test pumping shall be run to waste
for an overall period of two hours using either the original pump or the CONTRACTOR's test pump.
The pump shall be run through the pump to waste piping in the wellhouse if the original pump is used,
or pumped to the ground if a test pump is used. CONTRACTOR shall provide the necessary
equipment to record the following data at four (4) flow rate steps (four total measurement steps) each
for a 30 minute pumped duration at the following pumping rates; 200 gpm, 400 gpm, 600 gpm, 800
gpm.
If using a test pump, record the following information;
1. Rate of flow using OWNER'S flowmeter and/or CONTRACTOR'S orifice at each flow rate.
