Clean And Evaluate The Existing Condition Of Well #7 Luke Air Force Base, Arizona 01 July 2016

1. OVERVIEW

The Arizona Department of Environmental Quality (ADEQ) standard for maximum Nitrate levels is 10mg/L (10ppm). The maximum level for Arsenic is .01mg/L (10ppb). Well # 7 has not been in use since June of 2009. At that time the nitrate levels were well under the limit. Arsenic levels were above the limit. We have no data from that time period, but recent samples indicate that Nitrate levels are approximately 4ppm and Arsenic levels are approximately 20ppb, twice the limit. The Arizona registration number for this well is 55-609884. It is 1,144 feet deep. The static water level is approximately 327 feet below ground level. It has an 18” diameter casing, and discharges into an 8” line. There are four (4) reported screen intervals at 534-561, 564-572, 904-922, and 965-975 feet below ground. Other wells on the base range from 740 to1150 feet in depth. The well was placed in service in 1968. It is 48 years old. The eight inch discharge line is currently capped. The pump can however discharge through a 4” bypass line that feeds into a storm drain.

2. DESCRIPTION OF WORK

2.1. This project includes all of the necessary tools, equipment, and manpower needed in order to clean, remove, test, evaluate, and analyze the condition of Well #7.

2.2. Performance Period: All work shall be completed within 183 calendar days after the Notice to Proceed (NTP) is issued.

2.3. Hazardous Material Abatement: No asbestos, lead or other hazardous substances are known to exit. The Contractor shall report any suspicious material immediately to the Contracting Officer

2.4. Design Drawings: This project does not require design drawings, but will require a simple one-line diagram indicating the locations for zonal sampling and keynotes regarding flow spinner flowmeter logging is to be conducted.

2.5. Calculations: In order to identify where the zone specific samples should be collected, a spinner flow meter tool will be lowered down the 3-inch diameter access tube into the well casing below the pump intake at three (3) different line speeds. Data collected will include the depth, line speed and impeller rotation rate of the spinner tool. With this data, the quantity of water entering the well casing, along with the well profile will be calculated. This information will then be used to identify the location of the specific zonal sampling points.

2.6. Survey: The contractor shall perform two (2) down-well video surveys; one before cleaning begins, and one after cleaning is complete. Details of how the survey shall be conducted are listed in paragraph 2.7.4 below.

2.7. General Construction:

2.7.1 Demolition: The Government does not expect or foresee any demolition in this project, but the Contractor shall contact the Contracting Officer (CO) or his/her designated representative if any demolition becomes necessary as a part of this project.

2.7.2 Well Evaluation: Pull existing pump equipment for access into the well. Inspect the pump column pipe, pump bowls, and ancillary equipment. Provide recommendations for repair, cleaning, and/or replacement.

2.7.3 Cleaning: Remove and clean the dedicated pumps. Mechanically clean the well casings/screens/perforations in order to remove scale and encrustation. Chemically clean the well casing in order to remove biocide buildup.

2.7.4 Video Survey/Log: Develop a video survey/log before and after the mechanical/chemical cleaning is completed. Perform Down Well Video Survey to:

2.7.4.1 Confirm total depth and diameter of the well.

2.7.4.2 Determine the static water level.

2.7.4.3 Evaluate the condition of the casing for breaks, tears and buckles.

2.7.4.4 Determine the location and conditions of the perforations.

2.7.4.5 Evaluate the amount and location of encrustation

2.7.5 Spinner Flow Meter Log: Conduct spinner flowmeter logging in order to identify distinct flow zones, their flow rates, and total contribution into the well.

2.7.6 Collect and analyze depth specific water samples from flow zones specified by the government after evaluating the results from the spinner flow meter log.

2.8 Zonal Sampling:

2.8.1 Install test pump equipment in order to collect down well zonal water samples below the pump intake. Existing pump-head equipment will not permit access of a spinner logging tool and sampling equipment.

2.8.2 Conduct a down well spinner log while pumping at a constant rate.

2.8.3 Conduct zonal sampling after 12 to 24 hours of constant pumping.

2.8.4 Analyze a minimum of five (5) dynamic zonal samples for arsenic, fluoride, nitrate, and Total Dissolved Solids (TDS)

2.8.5 Review the zonal sampling data in order to determine/recommend which zones might be sealed off in order to improve the pumped ground water quality.

2.9 Testing And Analysis:

2.9.1 The Contractor shall ensure the selected laboratory is certified by the Arizona Department of Health Services. The Contractor shall analyze and test environmental samples using standardized methods in current editions of approved testing references such as SW-846,”Test Methods of Evaluating Solid Wastes, Physical/Chemical Methods”; 40CFR 136, “Guidelines Establishing Test Procedures for the Analysis of Pollutants”; and ”Standard Examination of Water and Wastewater”. The Contractor shall ensure the defensibility of test and analytical results through execution and scientifically sound activities as outlined in the appropriate portion of the approved Sampling and Analysis Plan (SAP).

2.9.2 The Contractor shall perform services in support of the AF Safe Drinking Water Surveillance Program and in compliance with the Safe Drinking Water Act (SDWA) In addition, the Contractor shall also comply with all applicable federal, state and local laws/regulations. All DoD and AF directives including but not limited to AFI48-144, AFI32-1066, AFI32-1067, and AFI10-246 apply as well.
