JOEL C. THIBODEAUX,
Plaintiff
CIVIL ACTION
VERSUS
NO. 12-1375
WELLMATE, ET AL.
Defendants
SECTION: “E” (5)
ORDER AND REASONS
Before the Court is Defendant’s motion in limine to strike the expert testimony of
Cynthia Smith. 1
BACKGROUND
Plaintiff Joel C. Thibodeaux (“Thibodeaux”) brings claims against Defendant
Pentair Water Treatment OH Company (“Pentair”) under the Louisiana Products Liability
Act (“LPLA”). 2 Thibodeaux was injured after the bladder in a water pressure tank,
manufactured by Pentair, ruptured on a platform operated by Chevron USA Inc.,
Thibodeaux’s employer and the plaintiff-in-intervention. 3 Thibodeaux alleges, among
other theories, that the tank “contained a manufacturing or design defect,” “is
unreasonably dangerous in construction or composition,” “is unreasonably dangerous in
design,” and “is unreasonably dangerous because an adequate warning about the product
has not been provided.” 4
On February 5, 2016, Pentair filed a motion in limine to strike the proposed expert
testimony of Cynthia Smith. 5 Pentair also sought to strike the proposed testimony of
R. Doc. 94.

Bryan Durig, 6 but counsel for Thibodeaux subsequently informed the Court that
Thibodeaux has withdrawn Durig as an expert witness and that Durig will not be called
to testify at trial. 7 Therefore, the Court DENIES AS MOOT Pentair’s motion in limine
as it pertains to the testimony of Bryan Durig.
Thibodeaux proffers Smith as a materials science expert to testify about the alleged
design, manufacturing, and warning defects of the tank at issue. 8 Thibodeaux filed an
opposition to Pentair’s motion in limine on February 23, 2016. 9
STANDARD OF LAW
Rule 702 of the Federal Rules of Evidence governs the admissibility of expert
witness testimony:
A witness who is qualified as an expert by knowledge, skill, experience, training, or
education may testify in the form of an opinion or otherwise if: (a) the expert’s
scientific, technical, or other specialized knowledge will help the trier of fact to
understand the evidence or to determine a fact in issue; (b) the testimony is based
on sufficient facts or data; (c) the testimony is the product of reliable principles
and methods; and (d) the expert has reliably applied the principles and methods
to the facts of the case. 10
The United States Supreme Court’s decision in Daubert v. Merrell Dow Pharmaceuticals,
Inc., 11 provides the analytical framework for determining whether expert testimony is
admissible under Rule 702.
Under Daubert, courts, as “gatekeepers,” are tasked with making a preliminary
assessment of whether expert testimony is both relevant and reliable. 12 The party offering

the expert opinion must show by a preponderance of the evidence that the expert’s
testimony is reliable and relevant. 13
The reliability of expert testimony “is determined by assessing whether the
reasoning or methodology underlying the testimony is scientifically valid.” 14 In Daubert,
the Supreme Court enumerated several non-exclusive factors that courts may consider in
evaluating the reliability of expert testimony. 15 “These factors are (1) whether the expert’s
theory can or has been tested, (2) whether the theory has been subject to peer review and
publication, (3) the known or potential rate of error of a technique or theory when applied,
(4) the existence and maintenance of standards and controls, and (5) the degree to which
the technique or theory has been generally accepted in the scientific community.” 16
The Supreme Court has cautioned that the reliability analysis must remain flexible:
the Daubert factors “may or may not be pertinent in assessing reliability, depending on
the nature of the issue, the expert’s particular expertise, and the subject of his
testimony.” 17 Thus, “not every Daubert factor will be applicable in every situation . . . and
a court has discretion to consider other factors it deems relevant.” 18 The district court is
offered broad latitude in making expert testimony determinations. 19
As a general rule, questions relating to the bases and sources of an expert’s opinion
affect the weight of the evidence rather than its admissibility and should be left for the
finder of fact. 20 “Unless wholly unreliable, the data on which the expert relies goes to the

weight and not the admissibility of the expert opinion.” 21 Thus, “[v]igorous crossexamination, presentation of contrary evidence, and careful instruction on the burden of
proof are the traditional and appropriate means of attacking shaky but admissible
evidence.” 22 The Court is not concerned with whether the opinion is correct but whether
the preponderance of the evidence establishes that the opinion is reliable. 23 “It is the role
of the adversarial system, not the court, to highlight weak evidence.” 24
ANALYSIS
In Smith’s report, Smith concludes that the Wellmate 12 water pressure tank at
issue was “unreasonably dangerous in construction and composition,” “unreasonably
dangerous in design,” and “unreasonably dangerous because the manufacturer failed to
provide adequate and sufficiently permanent warning[s] about latent dangers associated
with this system.” 25 Her report states that her investigation included “the analysis of an
injection molded PVC drain pipe, a fractured elastomer air cell that was blow molded
during manufacturing, a fiber-reinforced composite tank, polymer warning labels, and
label adhesives that may have been subjected to weathering conditions during service.” 26
Pentair’s motion calls into question Smith’s qualifications to render an opinion in
this matter. 27 In addition, Pentair argues that Smith’s testimony is speculative, lacks
foundation, and is unreliable. 28

Smith has a bachelor’s degree in materials science and engineering. 29 Her
curriculum vitae reflects that she has a wide array of experience regarding materials
science and investigative chemistry. For example, for more than five years, Smith served
as the manager of material analysis with Uponor North America, “an engineering services
laboratory dedicated to failure analysis of metals and extruded/injection molded
polymers, investigative chemistry, process research and development, and materials
engineering related to warranty claims resolution and new product development.” 30 For
six years, she worked as a metallurgical failure analyst with AlliedSignal Engines, where
she “[c]onducted sophisticated failure analysis of numerous gas turbine engine
components,” according to her curriculum vitae. 31 Smith also has experience managing a
failure analysis and investigative chemistry group, where she conducted “hands-on failure
analysis” for projects involving materials such as metals, plastics, and composite
systems. 32 Since 2009, Smith has been the principal, president, and technical manager of
Paragon Polymer Consulting, LLC, which provides forensic consulting for metals,
polymers, and composites; failure analysis; investigative chemistry; and materials testing
and analysis. 33 Her “[a]nalyses include determination of the root cause of failure,
evaluation of material integrity, and investigation to determine if a manufacturing defect,
environmental degradation, atypical residual and/or applied stresses, or improper
installation may have contributed to failure.” 34

The opinions contained in Smith’s report regarding the construction, composition,
and design of the Wellmate 12 tank are based on Smith’s “detailed visual examination”
and “detailed inspection” of the materials in the tank and bladder at issue. 35 According to
Smith’s report, both she and Pentair’s engineering expert Tom Proft “jointly performed
the following analyses to evaluate the condition of the incident components:
Stereomicroscopy[;] Scanning Electron Microscopy with Energy Dispersive X-ray
Spectroscopy[;] Tensile Testing . . . [;] Tear Testing . . . [;] Fourier Transform Infrared
Spectrometry[;] Differential Scanning Calorimetry[;] Melt Flow Testing . . . [; and] Shore
A Durometer Hardness Testing.” 36 Much of Smith’s report details her findings as a result
of each of the analyses. 37
The Court finds that, given Smith’s extensive experience, she is qualified to testify
about the material composition, construction, and design of the tank, the bladder, and
the drain assembly. 38 The Court further finds that Smith has relied on sufficient facts and
that her opinions regarding the material composition, construction, and design of the
tank are the product of reliable principles and methods—namely, the analyses she
performed jointly with Pentair’s engineering expert. Smith’s report and proposed
testimony are directly relevant to the issues in this case, as she provides information about
the composition and construction of the tank and bladder as well as opinions regarding
whether the tank at issue had a design or manufacturing defect. 39

39 Pentair does not argue Smith’s opinions are irrelevant to the issues in this case. See R. Doc. 94-1.

Smith, however, may not provide testimony regarding the adequacy of the warning
labels, regarding whether warning labels were present on the Wellmate tank at the time
the tank left Pentair’s control, regarding the adhesion and permanency of the warnings
on the tank, or regarding whether Pentair’s procedure for affixing the primary brand label
was more rigorous than its procedure for affixing the warning labels to the tank. In
Smith’s report, she opines, “I[t] appears that very little priority was given to the need for
permanency with regard to warning labels.” 40 She notes that a label exhibiting the
Wellmate brand name remained on the tank’s exterior while the warning labels Pentair
attached to the tank at the time of manufacture no longer remained on the tank’s exterior
or drain pipe. 41 From this, she concludes that “Pentair possessed the knowledge and
ability to provide a greater level of permanency for their warning labels at the time of
manufacture than appears to have been demonstrated by the warning labels that were
allegedly applied to the incident tank . . . .” 42 Further, Smith remarks skeptically in her
report that the tank ever had warning labels affixed to it as Pentair contends. For example,
she states in her report, “Pentair possessed the knowledge and ability to provide a greater
level of permanency for their warning labels at the time of manufacture than appears to
have been demonstrated by the warning labels that were allegedly applied to the incident
tank (if those labels were actually applied at all).” 43 In her deposition, Smith testified,
“[A]t this point I have not found convincing evidence that there necessarily ever was a
label on the drain pipe.” 44

Smith’s conclusions with respect to the existence and permanency of the warnings
appear to be almost entirely drawn from the fact that the warnings were not present at
the time she inspected the tank, several years after the tank left Pentair’s control. 45 She
did not know what kind of adhesive Pentair used to attach the labels to the tank, and she
did not test the adhesive on any warnings associated with Wellmate tanks. 46 Because her
testimony with regard to the adhesion and permanency of the warnings on the Wellmate
tank is not based on sufficient facts or data and is not the product of reliable principles
and methods, the Court will not allow Smith to provide testimony on the adequacy,
existence, or permanency of the warnings. 47
Moreover, Smith may not provide testimony regarding the likelihood that other
similar accidents occurred. 48 Smith did not address this issue in her report. It does not
appear that Smith will be asked to testify about the likelihood that other similar accidents
occurred, but, to the extent she is, it will not be allowed.
CONCLUSION
IT IS ORDERED that Pentair’s motion in limine to strike the expert testimony of
Cynthia Smith is GRANTED IN PART AND DENIED IN PART as set forth above. 49
See id.; R. Doc. 102-13 at 9–10.
R. Doc. 102-13 at 9–10.
47 See FED. R. EVID. 702.
48 Smith testified in her deposition that Pentair has “reported with tremendous specificity that [it has] not
had any other reports of failures occurring in this exact manner, with this exact air cell, with this exact tank.
The sheer specificity of [its] answer, in my opinion, implies that [it] indeed [has] likely had other failures
and [it is] using semantics to bury those failures.” R. Doc. 93-14 at 34–35.
49 R. Doc. 94. Pentair also filed a motion in limine to preclude Thibodeaux’s experts from providing
speculative testimony. R. Doc. 125. That motion was filed beyond the deadline to file motions in limine
regarding the admissibility of expert testimony and was therefore untimely. See R. Doc. 74 at 6. Accordingly,
that motion will not be considered and is DENIED. Nevertheless, many of the issues raised in that motion
have been addressed herein.
