SUBJECT: City of Clearwater RO2 Class I Injection Well Mechanical Integrity Test Results

- City Project No. 23-0025-UT

DATE: January 22, 2024

WSP-USA, Inc. (WSP) has prepared this technical memorandum (TM) to provide a description of procedures and results of the mechanical integrity test (MIT) performed on the Class I concentrate injection well at the City of Clearwater Reverse Osmosis Water Treatment Plant No. 2 (RO2). The MIT was implemented to comply with Specific Condition I.B. (Mechanical Integrity and Mechanical Integrity Testing) of Class I Operating Permit No. 306496-007-UO/1X. A construction diagram of the Class I Injection Well (IW-1) is provided as Figure 1. The well is constructed with 8.85-inch inside diameter Red Box 1500 fiberglass reinforced pipe (FRP) to a depth of 719 feet below land surface, and a total depth of 1,020 feet below land surface.

The MIT consisted of a radioactive tracer test (RTS), a casing pressure test, and a video survey of the entire well. The video survey was performed by Applied Drilling Engineering (ADE) and Advanced Borehole Services (ABS) on October 16, 2023. The pressure test was performed by ADE on October 24, 2023, and the RTS was performed by ADE and MV Geophysical Services (MVGS) on November 1, 2023. The MIT was performed in overall accordance with the FDEP approved MIT Plan dated July 18, 2023. This TM provides a description of the procedures used for the MIT followed by a description and interpretation of the results. The TM also includes a graphical and tabular summary of monthly operational and water quality data reported in the monthly operating reports from November 2018 through November 2023.

MIT Procedures

1) The video survey was performed on October 16, 2023, by ABS because MVGS’s downhole camera was out of service, and it was not known whether it would be repaired by the scheduled date for the RTS. The video was run from land surface to a total depth of 1,011 feet below land surface (bls).

2) Notice of the MIT dates was sent to the Southwest FDEP office on October 16, 2023. The notice referenced October 24th for pressure test and November 1st for the RTS.

3) The pressure test was performed on October 24, 2023. The test was not observed by FDEP as we were informed on the day of the test that staff was not available. As documented in the email included as Appendix A, Mr. Preston Graves stated that the test could proceed and that FDEP staff would be on site to observe the RTS. The well head was removed at the base of the tee section to the discharge line. An inflatable packer was set in the FRP injection tube at a depth of 710 feet bls. A temporary well head flange cover with connections for a water line, pressure line, and calibrated pressure gage with one pound per square inch (psi) increments was installed on the well head flange. A copy of the pressure gauge calibration chart dated October 10, 2023, is provided in Appendix B. The casing was filled with water and placed under 69 pounds per square inch (psi) and held for one hour. Pressure readings were recorded at 10-minute intervals and are shown in Table

1. Photographs of the pressure gage readings and bucket test are also included in Appendix B.

4) The RTS was performed on November 1, 2023. The injection well was shut down at 9:00 pm on October 31st. The wellhead was removed above the tee section to the concentrate discharge line by ADE. A temporary standpipe and pack-off was installed on the well head to run the geophysical logging tools through.

5) MVGS ran a background high resolution temperature and natural gamma log of the well to the total depth of 1,011 feet. Temperature, differential temperature, and gamma responses are shown on the log titled, High Resolution Temperature Log in Appendix C.

6) The radioactive tracer survey (RTS) was performed using a tool that includes three gamma-ray detectors and the ejector for the radioactive tracer. The ejector was set 13.75 feet above the bottom of the tool. The bottom detector (GRB) was set 1.15 feet above the bottom of the tool (12.6 feet below the ejector). The middle detector (GRM) was set 10.37 feet above the bottom of the tool (3.38 feet below the ejector). The upper detector (GRT) was set

23.78 feet above the bottom of the tool (10.03 feet above the ejector). Tools were calibrated and field tested. The background gamma log was run together with the background temperature log described in item 5) above. The background gamma response for each detector is shown on the attached log titled, Background Gamma Ray. Upon completion of the background log, the tool was set with the ejector at a depth of 719 feet below land surface (bls) (the bottom of the FRP casing). The tracer material was a volume of Iodine 131 equivalent to approximately 1 to 2 millicuries. The assay date was November 1, 2023.

A copy of the assay certificate is included in Appendix B. The RTS was observed by Emmalise Hunter (FDEP Southwest District).

7) The well was flushed with three casing volumes of RO concentrate (6,500 gallons) prior to the start of the test (as discussed in the July 18, 2023, MIT Plan). After injection of three casing volumes, fresh potable water was injected at rate of 16 gallons per minute (gpm) to provide a flow rate of approximately 5 ft/min in the well for the dynamic tracer test. Time drive monitoring was started, and a slug of tracer was ejected. Gamma-ray levels were monitored for 60 minutes after ejection with the tool held stationary to observe tracer movement. This release was confirmed by detection of the tracer at detector GRM. The 60-minute log in place gamma response for each detector is shown on the log titled, D1: 1 mCi @16 gpm @ 719 ft in Appendix C.

8) Tracer was not detected at detector GRT, therefore a log out of position pass was made from the initial logging position to 200 feet above the bottom of the casing (516 feet bls).

The gamma response for each detector is shown on the log titled, Log Out of Position Pass 1 (Appendix C).

9) The well was flushed with 6,000 gallons of RO concentrate to remove the previous tracer ejection. The log out of position pass was repeated to confirm that the tracer was flushed from the well. The gamma response for each detector is shown on the log titled, Log After Flush Pass 1 (Appendix C).

10) The dynamic test was repeated with injection continued at rate of 16 gallons per minute (gpm) to provide a flow rate of approximately 5 ft/min in the well. Time drive monitoring was started, and a slug of tracer was ejected. Gamma-ray levels were monitored for 30 minutes after ejection with the tool held stationary to observe tracer movement. This release was confirmed by detection of the tracer at detector GRM. The 30-minute log in place gamma response for each detector is shown on the log titled, D2: 1 mCi @16 gpm @ 719 ft (Appendix C).

11) Tracer was not detected at detector GRT, therefore a log out of position pass was made from the initial logging position to 200 feet above the bottom of the casing (516 feet bls).

The gamma response for each detector is shown on the log titled, Log Out of Position Pass 2 (Appendix C).

12) The well was flushed with RO concentrate while the tool was lowered to 900 feet bls where the remaining tracer was ejected. Upon completion of the flush, a final gamma ray pass was made over the entire well. The gamma response for each detector is shown on the log titled, Final Gamma Ray Pass (Appendix C).

MIT Results

1) The background temperature log showed a gradual increase in temperature from 76o at the top of the water column to 80.4o at the bottom of the casing as shown on the log titled, High Resolution Temperature Log. Temperature then increased from 80.4o to 81.3o from the bottom of the casing to the bottom of the well. The rate of increase was greater below 920 feet. The background gamma log showed similar responses from the three gamma sensors as shown on the log titled, Background Gamma Ray. The increase in gamma activity below 650 feet bls marks the top of the Avon Park Formation. The decrease at 724 feet bls marks the bottom of the casing and the larger open borehole diameter.

2) In RTS dynamic test 1, the first arrival of the tracer at GRM occurred at 35 seconds after ejection as shown on the log titled, D1: 1 mCi @16 gpm @ 719 ft. Gamma levels at GRM returned to near background at approximately 1,260 seconds. Tracer was not detected at GRB or GRT during the first dynamic test. As shown on the log titled, Log Out of Position Pass 1, no indication of tracer was observed above the tracer ejection point on the log out of position pass. A gamma response was detected at bottom of the injection tube (719 to 724 ft bls) in GRM and GRB. This response was also observed on the Log After Flush Pass 1. This peak could be indicative of residual tracer within the remnant grout plug inside the 24-inch casing below the bottom of the injection tube.

3) In RTS dynamic test 2, the first arrival of the tracer at GRM occurred at 30 seconds after ejection as shown on the log titled, D2: 1 mCi @16 gpm @ 719 ft. Gamma levels at GRM returned to background at approximately 600 seconds. Tracer was not detected at GRB or GRT during the second dynamic test. The slight gamma peak at 20 seconds after eject on GRB is attributed to “motor noise”, which is an electrically induced signal from activation of the ejector. As shown on the log titled, Log Out of Position Pass 2, no indication of tracer was observed above the tracer ejection point on the log out of position pass. The same gamma peak from 719 to 724 ft bls observed in GRM and GRB on Log After Flush Pass 1 was observed on Log Out of Position Pass 2.

4) The remaining tracer in the tool was ejected at approximately 900 ft bls while the well was being flushed with RO concentrate. The log titled, Final Gamma Ray pass shows that tracer was present from the final ejection depth of 900 feet to 800 feet bls. The gamma peak in GRM and GRB from 719 to 724 ft bls described in 2) and 3) above was also present on the Final Gamma Ray Pass.

5) The video survey showed that the entire length of injection tube was coated with a layer of calcium precipitate scale that obscured the view of casing joints. This scale was also observed on the open borehole wall. The precipitate scale is likely due to the blending of concentrate from the Reverse Osmosis Water Treatment Plant No. 1 (RO1) into the source water stream for RO2. Movement of loose debris in the borehole indicated an upward flow gradient in the borehole from 913 feet to a cavity at 729 feet bls. Vertical flow was not observed above 728 feet. The view was obscured by excessive debris in the water column below 1,010 feet bls. A copy of the video was sent to the UIC Section in the FDEP Tallahassee office. The video runs in the open-source VLC video viewer program.

6) The pressure test results shown in Table 1 indicate that the pressure decreased from 69 psi to 67.3 psi in 60 minutes, which converts to a pressure loss of 2.5 percent. The standard for a passing test is no pressure change more than five percent of the initial pressure for a period of sixty minutes. Upon completion of test, the valve at the well head was opened to release the pressure and one gallon of water was collected before the pressure dropped to zero psi at the well head.

The results of the RTS showed that there was no movement of tracer above the bottom of the casing.

The results of the pressure test showed that the casing held pressure at 69 psi within the five percent allowable decrease in one hour. Based on the results of this MIT, the injection well is shown to meet the standards for mechanical integrity.

EXTERNAL MESSAGE

This email originated outside of DEP. Please use caution when opening attachments, clicking links, or responding to this email.

Good Morning Preston – this email is to confirm our conversaƟon on October 24 that the pressure test on IW- 1 at the Clearwater RO2 Water Treatment Plant could proceed without FDEP oversight due to no FDAEP staff availability to observe the test, and the City being unable to postpone the test without having to shut down both the RO1 and RO2 WTP’s. The test was successful. I will provide documentaƟon with the MIT report including photos of the pressure gauge taken at 10 minute intervals during the test, and a video of the pressure release bucket test at the end of the test. We appreciate your flexibility to allow us to proceed, and look forward to seeing you on November 1 for the radioacƟve tracer test. I will noƟfy you on October 31 with the esƟmated Ɵme of the start of tesƟng on November 1.
