EXECUTIVE SUMMARY
Recommendation to approve a Work Order in the amount of $980,000.00 to Youngquist
Brothers, Inc., for the repair and replacement of a mechanical failure of the North County
Regional Water Treatment Plant Deep Injection Well No.2. Steel Injection Tubing, Project
70008.1.
OBJECTIVE: That the Board approves a work order to repair the failed steel tubing of the
North County Regional Water Treatment Plant (NCRWTP) Deep Injection Well (DIW) No.2 to
restore its mechanical integrity to allow it to be placed back into service as mandated by the
Florida Department of Environmental Protection (FDEP) permit conditions and to reliably serve
our water customers.
CONSIDERATIONS: The NCRWTP has two DIW's which serve as disposal sources for the
reject concentrate liquid resulting from the process of treating raw water and producing potable
water. DIW No. 1 and DIW No.2 were constructed and placed in service 1993 and 1996,
respectively. The FDEP permit requires that the NCRWTP has two DIW's in operation for
sustainable and reliable service. On May 13, 2009, DIW No.2 exhibited a pressure drop that
was discovered by plant operations. Based on past experience, this condition is indicative of a
Steel Injection Tubing (SIT) failure as was discovered and repaired in both wells in 2002. At
that time, both wells were repaired by replacing the SIT with like materials as directed and
_ permitted by the FDEP.
In 2004 DIW No. 1 experienced another failure of its SIT, and through negotiations with the
FDEP, they allowed the repair at that time to be performed by replacing the SIT with fiberglass
reinforced pipe (FRP) due to past poor performance of the original SIT material. The
replacement was completed in 2005. In 2007, the FDEP issued a permit to replace DIW No. 2's
SIT with Fiberglass Reinforced Plastic (FRP) as a preemptive and proactive solution to the
problems encountered with steel tubing. At that time, since there was no indication that DIW
No.2 was also failing, it was prudent business risk to continue operation of DIW No.2 as there
was no indication of mechanical problems, and therefore there was additional useful life
remaining for this well.
On May 13, 2009, DIW No.2 experienced the symptoms of a tubing failure and therefore had to
be shut down from operation. The only way to verify the extent of the disrepair is to disassemble
the well and pin point the cause(s) of failure. This is an extensive effort that requires heavy
equipment and necessitates extreme experience and knowledge of the DIW. Fixed Term
Contract #06-3887, Annual Contract for Well Drilling and Maintenance, is in place for this type
of work. The normal Purchasing procedure is to obtain quotes from all vendors under this
contract. In this case there are only two vendors; Youngquist Brothers and Jaffer. Youngquist is
far more experienced in this type of work, is local, originally constructed both wells on this site
and others in the County system, and has similarly repaired both wells successfully in the past.
--
This is an exigent situation governed by FDEP permit conditions. The FDEP requires that both
wells be in service as a condition of the operating permit. It is therefore necessary to contract
with the more experienced and equipped well repair contractor, Youngquist Brothers, Inc., who
has previous experience with, and intimate knowledge of both wells on an emergency basis. The
Executive Summary
Recommendation to Approve NCRWTP DIW No.2 tubing

repair will consist ofremoving the failed SIT and replacing it with a new FRP. No new permit is
required for this work since it can be performed under the previous FDEP approved permit.
Timely completion of the repair is critical to the reliable operation of the NCRWTP and is an
FDEP permit condition. A fair and reasonable best market value price was negotiated with
Youngquist Brothers. Therefore staff requests that the Board waive the requirement for
obtaining quotes from both vendors, and to approve award to the best valued, more experienced,
and best equipped contractor, Youngquist Brothers.
FISCAL IMPACT: A budget amendment is necessary to transfer $1,018,500 ($980,000 for
construction and $38,500 for engineering services) from Water Capital Project Fund 412
Reserves, to Project 70008.1. The source of funds is Water User Fees.
LEGAL CONSIDERATIONS: This item has been reviewed and approved by the County
Attorney's Office, is not quasi-judicial and requires no ex parte disclosure, requires only a
majority vote for approval, and is otherwise legally sufficient for Board action.-SRT
GROWTH MANAGEMENT IMP ACT: This project meets cun'ent Growth Management Plan
standards to ensure the adequacy and availability of viable public facilities.
RECOMMENDA TION: That the Board of County Commissioners, as Ex-officio, the
governing Board of the Collier County Water-Sewer District, waive the formal quote under
contract 06-3887 and approve a Work Order to Youngquist Brothers, Inc., in the amount of
$980,000.00 and approve the necessary budget amendment(s) for the repair and replacement of
the NCRWTP DIW No.2 SIT tubing with FRP.

Part I. Directions, E.
Part of the 7.5 millUte U.S. Geological Smvey topographic map of the North County Regional
Water Trealment Plant (NCRWTP; Belle Meade NW and Corkscrew SW quadrangles) is
provided as Figure 1, Injection wells IW-1 and 1\1\'-2 and the dllal-zone monitor well are
located in the SW 1/40f the SE ] 14 of St~ction 35, Township 48 Sou lh, Range 26 East. The
approximate latitude and longitude of injection well 1\'\'-2 is 26014'42" North, 81040'41" West.
P:lrt II. Genei'll! Information, Subpart B. Gcneral ]lrojcct Description
lnjection well n'\'-2 was consh'l1cLed bet,veen NovernbeJ' 1995 and April 1996 to provide 100
percent redundant capacity for injection well IvV-1, vl'hich was completed in March 1993.
Injection well IW-2 has a permitted capacity of 6.3 l11.illion gallons per day (Mgd) of liquid
waste. The original waste flow disposed of in the injection well system ,vas reject concentrate
\ovateI' from a m.embrane softening facility. The NCRWTP has subsequently been expanded to
include a reverse osmosis desalination facility. Reject concentTate from the reverse osmosis
desalination facility is also disposed of in injection wells lW-1 and 1W-2. Excess reclaimed water
n'om the North County Water Reclamation Facility (NCWRF) was also formerly disposed of in
the NCRWTP injection well system. With the construction ofthc NC\VRF injection system, the
pipeline between the NCWRF and NCRWTP has been discollnected,
The 16-inch diameter steel injection tubing in well IW-2 developed a leak and was replaced with
another steel injection tubing in 2002. Injection well 1W-2 passed a mechanical integrity test in
February 2006. Although the injection well lW-2 tubing still has mechanical integrity, Collier
County seeks to permit the replacement of the injection tubing now, so that the replacement
could be performed expeditiously should a leak develop in the tubing in the future. The
replacement tubing will be a 15.8-inch diameter, 0,66-inch thick wall Red Box 1250 fiberglass,
as manufactured by Future Pipe Industries, or an approved equivalent. The annulus bct\vecn the
injection casing and tiberglass injection tubing will be cemented.

H. Gener'al Pr'oject Description
Proiect Summarv
The project involves the replacement of the injection tubing in the Collier County NCR WTP
injection well IW -2. The entire 16-inch diameter, steel injection tubing will be removed and
replaced \\'ith a l5.8-inch diameter fiberglass tubing. The replacement process calls for reuse
of the existing YBI positive seal packer to support the fiberglass injection tubing during
cementing. A schematic diagram showing the existing well construction and proposed
altemate design is provided in Figlll'c 2 and a diagram of the proposed m1l1ulus cement
packer assembly is provided in Figul'c 3. The annulus will be pressure grouted from the
bottom of the annulus u])\vard in a single stage.
In the event that the existing YBl packer is unusable. the annulus will be cemented while the
fiberglass casing is hung from the top of the wcll sur1~lce.

The total historic injected volume in the NCRWTP injection well system is 9,352 MG
tlU'ough December 2005. The only anticipated expcmsion of the NCRWTP is the
addition of a high-pressure reverse osmosis (RO) skid, which at its design capacity
would generate 1 MGD of concentrate. The high-pressure RO system would be used
only to meet peaks in demand as it will be the most expensive water to produce. Future
annual injection wen disposal volumes will likely be comparable to current levels,
The projected future disposal volume, for the purpose of the determining the area of
review, is estilnated as 11 times the maximum historic annual concentral'e disposal
volume (1,240 in 2003) or 13,640 MG, which include the requested and next 5 year

futu]'(~ injection volume is 22,992 IvIG.
The thickness of the injectate-invaded zone in well IW-1 and 1W-2 is over 600 feel thick,
as documented in the completion repol'ts for the injection wells. However, for the
purpose of establishing a conservative area of n~view, a 200 ft injecLion zone thid-ness
and a porosity of 20% are used. Using a cylindrical flow assmnption, the "zone of
endangering influence" radius (R) is c<11culated as follows using the above discllssed
injected volume, injection zone thickness and porosity:
R2 = ((22,992 X 106 gal * 0.13,1 fP/g<1I)/(200 ft ". 0.20 II)" 3J4))
R2 == 24,529,680 f12
R == 4,953 It or 0.94 nrues
The l-mile radius are<1 of review is thus appropliate for the NCRWTP injection ,.veIl
system, as the calculations include many vcry conservative assumptions.
Detailed area of review studies for a one-mile radius area were submitted to the
Depal'l111ent with the well nV-l and 1W-2 construction pennit, operation pennit, and
operation pennit I'enev.'al applications. The one-mile mdius area is shown on a
topographic map in Figure 1. The well inventories were conducted using data frOln the
Collier County Pollution Conh'ol Division, Florid" Geological Survey (oil and gas and
geologic investigations sections), U.s. Geologica! Snrvey, and the South Florida 'Vater
Management District. The locations of all known intennediate and Floridan aquifer
system wells are 5hO\...'n on Figm'e 4. Available details on the intermediate and Floridan
aquifer system wells within the area of review are provided in Table 2.
Over 200 Tamiami aquifer wells (total depths mostly < 110 it) for residential and! or
il'l'igatiol1 use have been installed in the area of review since the original area of review
investigation in 1991 for injecLion well IW~l, A listing of all post-1991 wells in the area
of review in the Collier COUl'lt)' Pollution Control Division (CCrCD) database is
provided ll1 Appendix A. All wells completed fro111 1991 to present would have had to
have been permitted through Collier County, so the CCrCD dat'dbase includes all wells
present ll1 the databases of other agencies.
The project site area has undergone extensive residential development since injection
well 1\^/-1 was constructed. Golf course lakes have been excavated on the adjoining
property to the north. These recently excavated lakes do not yet appeal' on local maps.
Review of the literature indicCltes Uwt there are no known faults in the area of I'evie'w.

the exception of NCEWTP IW-I ilnd DZtvfI'V-I, whose construction was supervised by
ViroGroup, Inc, and test wells CC-27D07 cmd CC-27008. Only two wells have been
constructed (other than injection we\1s IW-I and IW-2) tIwt pcnctTated as deep as the upper
monitor zone of the dual zone monitor well, which is open between 900 tme! 99.5 ft his. A 6-
inch diameter test well (MC-SOOO) was drilled to a total deptIl 1201 ft bls. Well MC-SUOO was
subsequently backfilled WiUI cement to 828 ft bls. A prodnction 'well (MC-S029; 1\0-5) for
the NCRWTP reverse osmosis water treatnwnt facility was drilled to a total deptll of 1070

Detailed information on hydrogeology of the NCRWTP ill"Hfl was provided to the
Department in the completion reports for injection well HAl-1 (submitted by ViroGroup, Inc.
in August 1993) and injection well IW.-2 (submitted by Missimer International, Inc. ill
Augnst 1996). The base of the USDW is locateel at approximately 1190 feet bls at the
NCRWTP. The bottom of the well IW-l and 1\'\'.2 injection casings are located at 2497 and
2498 ftbIs, respectively. 'Vater quality information obtained during the drilling ofinjecHoIl
well IW-2 indicates that the top of the injectate invaded zone from well IW-l is located at
approximatl'ly 2406 it bls. The base of the USD'i'\' ,",,'as thus located approximately 1214 ft
above the injectate invaded (injection) zone.
A regional north-south hydrogeologic cross section was prepared from data in the injection
well completion J"Pporls. Tlw locations of the injectiol1l.vells and line of the cross-section cu'e
shown on Figure 5 and the cross-section is included in Figure 6. The USDW is located above
the injection zone ilnd a confining zone is prer.ent between the base of the USD'i'\' and the top
of the injection zone tluollghout the area of review.
As shown ill Figure 6, there is fin overall regional trend for the base of the USDW to occur at
progressively shClllower depths from north to south in ,"",estern Lee and Collier Counties, In
the general vicinity of the NCR'i<\'TP, the base of the usnw appears to be relatively flat. The
base of tile lJSDW occurs at approximately 1190 at the NCR\NTP and at 1, 198-1,231 ft b]s
approximately 5.5 miles to the sou lh at the Collier SCI~WTP injection wellIW-l. Pnrther
sonti1, the base of the USDW occurs at approximately 969 n bls at the Collier SCWRF, vd'lich
it; located approxil11fltely ]2 miles from the NCI~'i"'TP.
The neal'est injection well site to tile east for \'\'hich the base of the USDW has been located is
[he Imlllokfllee injecliDll well, which is located approxima tely 19 miles northeast of the
NCRWTP. The lmmokalee injection "\ovell was completed in March 2002. According to
information contained in the injection well completion report, prepared by CH2M Hill, the
base of the USDW at the ImDloka]ee injection well site is located at approximately 1,960 ft
bls, which is approximately 770 feet deeper tllan at the NCRWTP, The average gradient of
the base of the USDW between the lnunokalee injection well site ilnd the NCRVv'TP is
approximately 40.5 feet per mile (770 feetj19 miles). 'fhe top of the injection zone was
located at approximately 2,404 ft bis in NCRWTP injection well I\t\7~2. Thus the base of tile
USDW does not intersect the injection zone at least as far cast as Inullokalee.
The regional groundwater flow direction in [he USDW aquifers ill the NeRW'IV vicinity is
to the sOlltin\'est, towmd the Gulf of Mexico.

There are no known wells in the area of review lhilt penetrate the injection zone other than
NCRWTP injection ,-veIls 1\<\'-1 and 1\1\1-2. No corrective actions are therefore required.
8. A celtification that the applicant has ensured, through a performance bond or other

Certification of Fi.nanci<lll{esponsibility documentation W,15 provided to Mr. mehard
DeuerJing, FDEP-TallahasscL' as part of the November 2003 renewal of the injection welllW-
2 operation permit. The cost estimates included conservative values for each activity,
plus a 20% contingency, The proposed well modification v./ill result in a reduction of
plugging and abandonment costs, because the replacement tubing v.'ill not be removed
and the casing volume, and thus cement requirements will be kss. The current financial

A mechanical integrity testwCls last completed on injection '....ell IW-2 in February 2006.
The results of the lest indicated th<lt injection well 1\1\1-2 has mechanical integrity.
Dual-zone monitor wen water qualitv data
Water quality data for the shallow and deep monitor zones and conccnb'ate are
compiled in Tables B-1 through B-3 of Appendix B. Plots of the vmious water (lunlity
parameters (conductivity, TDS, chlol'ide, sodium, sulfate, andTKN) <Ire plotted versus
thne in Figures C-l through C-3 for tile upper (shallow) monitor zone, Figures C-4
through C-6 for the lower (deep) monitor zone, and Figures C-7 through C-9 for the
concen !l'a te.
The monitoring well data has random variation, but there is no suggestion of any long
term trends of changes in salinity, such as would be expected to OCClll' if upward
migration of injected fluids had occurred. If snlinity were changing over hille, then the
same trend would be evident in all the salinity parameters (specific conductance, total
dissolved solids, chlm'ide, and sulfate). The increase in the salinily of the concentrate in
late 1999 reflects the reverse-osmosis desalination facility coming on line,
Monitor well pressure data
Average daily monitor well pressure (upper and lower zone) versus time is provided in
Figure 0-1 in Appendix D. There is no trend of either increasing or decreasing pressure
(head) with time in either ti,e upper or lower monitor zones.
I-lydroj2nemnntic svstem data
Data on amlUlar pressure, hydropneumat:ic tank fluid level, and fluid and pressure
added have been submitted to the Department in the Monthly Operating Reports,
The monitoring data since the installation of the replacement tubing in October 2002
are SUllllllilrized in Table 3.
Since the tubing replacement, RlUllllal' pressure and fluid level in the
hydl'opneumalic tank have fluctuated due to fluid expansion and conh'action caused
by seasonal temperature changes, but there are no long term henda. It has never
been necessary to add fluid to the hydropnematic system., and there has been no
need to add pressure since the June 2004. The historic monitoring data thus indicate
that the injection casing and htbing have mechanical integrity.

time and eneh other Me providcd as Figures D-2 and D-3.
Averuge daily injection pressure data shows no evidence of an increase in injedion
pressure over time, such as would occur if the h'ansmissivity of the injection zone had
decreased over time due to clogging of pores. Average monthly injection pressures have
always been less than 40 psi and the maximum injection pressure has been less than 75
psi. The calculated specific injectivity values have t1uchlatcd considerably over the
monitoring period, but have consistently been over 200 gpm/psi for the operation
history of the well, ,.\'11i('h is acceptable for the design capacity and consb'uction of the
well.
Injection welllW-l will continue to bE' operated ill' a maximum rall~ of 63 IvIGD, which
conesponds to a velocity 8 ftl sec. The anticipated injection presslI1'e are similar to
historic values (average daily pressure < 40 psi). The maximum permitted injection
pressure of 100 psi should not be exceeded.
(4) The actual injection procedure
The injecl:ion procedures <It the NCJ~V\TfP are discussed in the "Injection Well rW-l and
IVV-2 Operation and Maintenance [V[anual" which was submitted to the Department in
July 2005. No changes in the injection procedures are herein pl'Oposed.
(5) The compatibility of the injected waste with fluids in the injection zone and minerals
in both the injection zone and confining zone.
The major solute concentrations of the groundwater in the injection zone and lower
monitor zone aTe very similar to those of Seil"\lVater. The solute concentration (salinity) of
the concentrate from the NCRvVTP is substantially less than that of the "vaters in the
injection and confining zone. The relatively dilute injected waters would not be
expected to significantly impact either the injection zone 01' confining zone rock, which
consists predominantly of dolomite. Dolomite has both Cllow solubility and dissolution
and precipitation rates under the temperature, pressure, a.nd pH conditions of the
injection zone.
(6) The status of correclive action on defective wells in the area of review
No defective wells that penetrate either the injection 01' confining zone are known to
exist within the area of review. No corrective actions are therefore neces~;ary.
(7) Record drawings, based upon inspections by the engineer or persons under his direcl
supervisioll, with all deviations noted.
Record drawings of injection Wt~][ 1\1\'-2 and the dUClI-zone monitor well have previously
been submitted to the DepiuunenL
