B. The White Sulphur Springs National Fish Hatchery is located at 400 East Main Street. White

Sulphur Springs, WV 24986 (Greenbrier County, West Virginia approximately 82 miles southeast of Charleston, WV. From I-64, take the White Sulphur Springs exit to U.S. 60).

1.03 EXISTING CONDITIONS AND NEW WORK

Wells A and B are adjacent to one another and supply water from the same aquifer. Wells A and B cannot be operated simultaneously. Wells A and B are equipped with 15 hp and 30 hp vertical turbine pumps, respectively. Well A is used primarily as a backup to well B and is also used at the beginning of the pumping season when hatchery water demands are lower.

Well E is located on property adjacent to the hatchery and owned by the City of White Sulphur Springs. A 25-horsepower submersible pump is installed within well E. In 1990, the hatchery contracted with the City of White Sulphur Springs to lease well E for a 99-year term.

Well F is located behind the Mussel Shop and is 6” diameter pipe and is 150’deep. The well pumps 50 gpm from a submersible Grundfos Pump, model # A7110000-P10847270. This well seems to have been constructed in 2008/2009.

See Appendix A for hatchery site plan and well locations, and Appendix B for well head photos.

WELL A

Well A is a 6" diameter rock well, constructed to a depth of 205 ft.; cased to a depth of 161 feet;

drilled in 1964; and test pumped to deliver 300 gpm at a pumping level of 110 feet. The well casing is grouted in rock. The pump is a Crane-Deming vertical turbine pump rated to deliver 300 gpm @ 120 ft. tdh. It was installed during May 1990 by Carl Johnson Plumbing.

1.05 WELL REDEVELOPMENT

A. The Contractor shall furnish all labor, equipment, chemicals, and materials necessary to clean, redevelop, and attempt to return to original capacity, each of the existing four (4) wells.

Page | 5

B. Measure and record static water level, depth of well, and test flow rate with corresponding vacuum gauge reading. These measurements shall be taken and recorded before, during, and after, cleaning each well.

C. Perform a pre- and post-rehabilitation, step drawdown test of the well to determine the approximate well yield before and after the rehabilitation.

a. This test shall be a step drawdown test and consist of operating the pump at a minimum of three (3) rates – approximately 40%, 70%, and a minimum of 100%- 105% of the rated design capacity where water levels and discharge pressures are monitored and recorded along with flow rates so that a representative performance curve can be generated for comparison to the original catalog curve for the pump. Each individual pumping rate shall be held constant for a minimum of 2 hours and until the drawdown in the well has stabilized, i.e., remains constant. Recorded drawdown measurements shall be required to confirm drawdown stabilization at each step.

b. The improvement in well capacity shall be reported in terms of percent increase in specific capacity measured as gallons per minute per foot of drawdown.

c. The test shall be performed by pumping the well to waste through a yard, hydrant, or station blow-offline so that flow measurements can be obtained using an orifice pipe or pitot tube.

D. As stated above, following both the pre- and post-rehabilitation yield tests of the well, conduct a video survey of the entire depth of the well for visual assessment of its condition before and after rehabilitation. The reason for the pre and post treatment video survey is to determine the well’s mechanical integrity, type of treatment required and overall effect of rehabilitation.

E. Each well shall be redeveloped using “boreblast” high-pressure gas impulse technology system; the “Airburst Technology” process, or by another equivalent means approved by the Contracting Officer. The redevelopment method shall include and be designed to provide effective chemical treatment using smaller amounts of chemicals than would be required by traditional well rehabilitation methods.

F. The “boreblast” system shall utilize a high-pressure gas impulse generator to deliver precisely timed high-pressure waves, transforming the potential energy in compressed gas into useful mechanical energy to remove scale and build-up from well screens and rock formations, disperse treatment chemicals, and remove fine materials from wells. The impulse generator shall be lowered into the well on a double braided high pressure hydraulic hose spooled on an electric or hydraulic winch. Depending on the chemistry of the groundwater, the impulse gas may be either an inert gas such as nitrogen or high-pressure air generated on site. The pressure shall be capable of being varied from a few hundred psi up to 4,500 psi.

The auto-firing mechanism, discharging at four second intervals, shall not require a special electrical circuit or electrical connections down-hole for operation. The impulse generator

Page | 6 diameter and gas volume may be modified in the field to meet well geometry and treatment requirements. The “boreblast” redevelopment process shall be conducted as follows:

a. The operator shall have the ability to select impulse generator diameter, gas chamber volume, and operating pressures to match the well dimensions and conditions.

b. To obtain maximum water column resonation the impulse generator shall be designed to discharge at a constant frequency of three to five seconds between discharges and shall not be adjustable.

c. The discharge gas shall be dry nitrogen delivered to the job site in pressures of 2,400 to

4,200 psi.

d. The bottom of the well shall be accurately determined by video or wire line.

e. Treatment shall begin in the lower most zone of water capture by the well. A zone is determined by soil and rock type.

f. A minimum of two bursts shall be made in each foot of zone to be treated.

g. A minimum of two passes shall be made through each treatment zone.

h. Following the initial treatment, the well depth shall be sounded to determine the amount of fill generated.

i. Excess fill shall be bailed or airlifted (forced with air pressure) out of the well. The well shall also be pumped to remove suspended solids.

j. Chemical treatment requirements shall be determined by analysis of a water sample to determine the appropriate treatment chemicals and shall at minimum consist of three (3) separate treatments; Muriatic acid; polyphosphate, and chlorine (Note, chlorine is toxic to fish). Following disinfection with chlorine, all residual chlorine shall be neutralized.

k. The treatment chemicals shall be placed in the treatment zones by tremie pipe.

Acid Treatment

1. The Contractor shall insure all OSHA standards regarding working with acids are followed.

2. The acid used to treat the well shall be 27.92% acid grade inhibited MURIATIC

ACID (hydrochloric acid).

3. The acid shall be placed in the bottom of the well; a small diameter (1/2" to 3/4") plastic pipe shall be inserted into the well, to a depth of three (3) feet off the bottom of the well, and enough acid shall be funneled into the plastic pipe to fill a five-foot

Page | 7 length of screen. The plastic pipe shall then be raised five feet and an equal volume of acid shall be added. This process shall be repeated until all the acid has been poured.

4. Vigorous surging of the well shall begin immediately following the introduction of the acid, and shall continue for two hours, whereupon the well shall be pumped clean and redeveloped.

5. For each acid treatment, the Contractor shall use a volume of 27.92% inhibited

MURIATIC ACID which is equal to twice the volume of the well screen.

6. The Contractor shall submit an acceptable plan for utilization (neutralization and disposal) of the acid pumped from the well before beginning this type of treatment.

Subsequent chemical treatment, if required shall be the same procedure as detailed above.

Polyphosphate Treatment and Chlorine Treatment (Disinfection)

1. The polyphosphate used for cleaning each well shall be sodium hexametaphosphate, and it shall be introduced to a well as water solution, after it has been dissolved by placing the polyphosphate in a wire basket or burlap bag and then suspending the container in water or as directed by manufacturer's recommendations.

2. For each 100 gallons of water contained in the well, the Contractor shall use about 30 pounds of polyphosphate and one pound of calcium hypochlorite or an equivalent amount of sodium hypochlorite.

a. If the calcium carbonate concentration in the ground water is above 100 ppm

(parts per million) (mg/l), the use of sodium hypochlorite is recommended instead of calcium hypochlorite.

b. Calcium hypochlorite or sodium hypochlorite that contain other chemicals of additives such as stabilizers, perfumes, algaecides, or other chemicals that are used for water supply disinfection should be certified that they follow or surpass the American National Standards Institute/NSF International (ANSI/NSF) Standard 60 for Drinking Water Treatment Chemicals – Health Effects, or an equivalent standard.

c. If a sodium hypochlorite solution is used it shall be less than 60 days old.

d. If tablets are to be used as a source of chlorine for a chlorine solution, they must first be broken up and dissolved in a 5-gallon pail or bulk tank.

e. The pH and temperature of the water used to make the chlorine solution shall be controlled to yield the greatest biocidal effects of the chlorine

Page | 8

f. Chlorine concentrations shall be kept between 250 ppm (parts per million) and 500 ppm.

g. The pH of the chlorine solution shall be controlled to less than 7.5.

3. The polyphosphate - hypochlorite solution shall be introduced to the well, vigorously surged for four hours, allowed to remain static for about 18 hours, and resurged for two hours, whereupon the well shall be pumped clean and redeveloped.

4. The Contractor shall record the pH and chlorine concentrations immediately and 24 hours after the final pump flush, or at the end of the redevelopment procedure. The Contractor shall neutralize all residual chlorine to ensure that no chlorine remains in the well water. All chemicals shall be pumped from the well and properly treated and disposed of.

l. After bore-blast and chemical treatments, check water turbidity:

1. The turbidity test will be the standard to determine the effectiveness of the well development work and as to when well development should be discontinued. In general, well development shall continue until the water turbidity does not exceed a maximum of one nephelometric turbidity unit (NTU). Turbidity measured by the degree to which particles in the water scatter light using an instrument named a nephelometer are reported as NTUs.

2. Conduct turbidity tests in the field by use of an EPA accepted portable type nephelometric turbidity meter or obtain turbidity results from a State of West Virginia approved laboratory. Calibrate portable nephelometric turbidity meter prior to using to taking readings according to manufacturer’s recommended procedures to ensure accurate test results.

3. Perform turbidity tests by checking turbidity after 4, 12, 18, and 24 hours of well development.

4. Contractor is responsible for paying for all costs incurred for testing.

m. After performing the post rehabilitation yield test and videotaping the well, return each well to service and submit copies of all records to the Contracting Officer.

1.06 REDEVELOPMENT AND TESTING
