OPINION

PER CURIAM:

Appellant-plaintiff Stephen Goewey appeals the dismissal for lack
of subject matter jurisdiction of his claim against appellee-defendant
United States (the "government"), and the summary judgment dis-
missal of his claim against appellees-defendants Fluor Daniel, Inc.
and its subsidiary FD Services, Inc. (collectively,"FD"). We affirm.

I.

In 1989, Stephen Goewey, then one-year-old, lived with his par-
ents, Julie and Kevin Goewey, in United States Naval housing owned
by the government. The government employed FD as an independent
contractor to provide maintenance and repair services for its Naval
housing. In August of 1989, Julie Goewey notified the government

                    2
that her house had a foundation level water leak. In response, the gov-
ernment issued a work order to FD, which stated:"WATERPROOF
ABOVE & BELOW GRND FOUNDATION LEAK." J.A. at 1485.

Consequently, on August 30, 1989, an FD employee reported to the
Goewey home to repair the leak. The employee dug a trench down to
the foundation of the house, and then applied roofing sealant to the
exterior of the house, from approximately three feet below to several
inches above the ground level of the house. On September 5, a second
FD employee returned to touch up the work done by the first
employee.

On September 12, 1989, Julie Goewey discovered her son sitting
in a puddle of the roof sealant near the house, with his body covered
with the sealant. Sometime thereafter, Goewey began experiencing
difficulties with his motor coordination, and he was eventually diag-
nosed as having a severe neurological disorder.

Goewey, through his parents, filed suit against the government
under the Federal Tort Claims Act ("FTCA"), 28 U.S.C. § 2671 et
seq., and against FD under state tort law, claiming that his neurologi-
cal disorder was caused by his exposure to Triorthocresylphosphates
("TOCP"), a chemical that he alleges was in the roof sealant. The dis-
trict court dismissed the suit against the government for lack of sub-
ject matter jurisdiction, and granted summary judgment in favor of
FD on the issue of medical causation.

II.

The district court dismissed the suit against the government for
lack of subject matter jurisdiction, concluding that Goewey's suit was
barred by sovereign immunity. According to the district court, under
the discretionary function and independent contractor exceptions to
the FTCA, see Williams v. United States , 

(4th Cir. 1995),
the FTCA did not provide a waiver of the government's sovereign
immunity. Therefore, Goewey could not sue the government for what
were the allegedly negligent acts of FD.

Finding no error in the district court's conclusion, we affirm the
judgment of the district court.

                    3
III.

The district court also granted summary judgment in favor of FD
on the issue of medical causation. Goewey's primary theory as to
FD's liability was that his exposure to TOCP, which he alleges was
present in the roof sealant, caused his neurological disorder. J.A. at
149. The district court excluded all of Goewey's expert witnesses on
the TOCP theory, and also Goewey's key expert witnesses on non-
TOCP theories, under Baughman v. American Tel. & Telegraph, 

(S.C. 1991), and Daubert v. Merrill-Dow Pharmaceuti-
cals, Inc., 

(1993). The district court then granted sum-
mary judgment in favor of FD. We affirm.

Under South Carolina tort law, Goewey was required to present
expert testimony that his theory of causation is more probably true
than any other alternative theory of causation. 

. Even if the proffered testimony is sufficient to satisfy
Baughman, however, the district court may still exclude expert testi-
mony if it finds that the testimony is unreliable. See United States v.
Dorsey, 

, 813 (4th Cir. 1995) (citing 

).

The district court first excluded the testimony of the three experts
who testified in support of Goewey's TOCP theory of liability -- Drs.
Robert K. Simon, M.D., Lorne K. Garretson, Ph.D., and Mohamed
Abou-Donia, M.D. We have carefully reviewed the record, and we
agree that the district court properly excluded this testimony.

No single one of Goewey's three witnesses could testify both that
TOCP was present in the roof sealant, and that, if present, TOCP
could cause Goewey's injury. One witness, Dr. Robert Simon, testi-
fied to the presence of TOCP, but could not testify to the causal con-
nection between TOCP and Goewey's injury. See J.A. at 164,
Appellant's Br. Reply at 15. Dr. Simon's own report, however, stated
that his conclusions were "consistent with the presence of TOCP, but
not confirmatory," J.A. at 1001, and that "the presence of interfering
substances . . . ha[d] decreased [his] confidence in the result," J.A. at
1002. While Goewey's two other witnesses -- Drs. Garretson and
Abou-Donia -- testified in support of the TOCP causation theory,
neither had any knowledge of the presence of TOCP in the roof seal-

                     4
ant. And another of Goewey's expert witnesses, Dr. Peter Bernad,
flatly rejected the TOCP causation theory. J.A. at 526.

All of the other evidence points to the absence of any TOCP in the
roof sealant. The uncontradicted testimony of the manufacturer of the
roof sealant is that "it does not currently use, and has never used, . . .
TOCP in any of its formulations." J.A. at 1515. This is consistent with
the Material Data Safety Sheet that accompanied the roof sealant here
at issue, which did not list TOCP as a constituent of the sealant.
Indeed, according to Dr. Garretson, TOCP is not ordinarily found in
roof sealant, and so would have had to have been added to the roof
sealant by FD's employees. J.A. at 279. FD's employees, however,
denied adding anything to the sealant. J.A. at 620, 854, 857.

Given this, we cannot say that the district court abused its discre-
tion in excluding this expert testimony as "not sufficiently reliable"
under Daubert, J.A. at 164, see United States v. Powers, 

, 1471 (4th Cir. 1995), or that it erred in rejecting the expert testi-
mony under Baughman. Accordingly, we affirm the district court's
grant of summary judgment in favor of FD on the TOCP theory of
medical causation.

As a secondary theory of liability, Goewey argues that chemicals
other than TOCP, which were present in the roof sealant, caused his
injury. In support of this argument, he relies on the testimony of three
additional experts -- Drs. Peter Bernad, David Hartman, and Allan
Lieberman. At the outset, we note that Goewey's primary theory of
liability -- TOCP exposure -- is flatly inconsistent with this second-
ary theory of liability, and so, under Baughman , summary judgment
in favor of FD is appropriate. Even assuming no such inconsistency,
however, the district court's judgment was still appropriate.

The district court properly rejected the testimony of Drs. Bernad
and Hartman under Daubert and Baughman as "insufficiently defi-
nite," "speculative," "conjectural," and "inconsistent." J.A. at 165-66.
Both experts could only speculate as to what caused Goewey's injury;
neither could point to a specific causative factor. Dr. Bernad, in
what he characterized as his "best conclusion," could only state that
"I cannot tell you what chemical, what material, whether in tar or
asphalt, whether toulene, xylene, solvents, trichloroethylene, whether

                     5
an acute organophosphorus reaction, whether chronic and so-called
organophosphorus-induced delayed neuropathy or any other disease
state ensued. Unfortunately, none of us were there." J.A. at 514. The
only specific theory that he offered, that Goewey suffocated on the
roof sealant, J.A. at 515, is flatly contradicted by the evidence that
Goewey's mouth had at most minimal contact with the roof sealant,
J.A. at 686-87, 805, 1495, a fact of which Dr. Bernad was not aware,
J.A. at 518. Similarly, Dr. Hartman, could state only that Goewey's
injury was "caused by a neurotoxin related to his exposure to tar,"
J.A. at 1121, but he could not specify which neurotoxin caused the
injury, J.A. at 1122. As his "personal favorite" explanation, Dr. Hart-
man could offer only a theory of "pyradine" exposure, J.A. at 1130,
which the district court noted was supported by but"a handful of arti-
cles and [was] based on experimental studies injecting . . . a pyradine
derivative into potatoes and mice," and thus could "not survive
Daubert analysis," J.A. at 166.

Since the district court made no reference whatsoever to the testi-
mony of Dr. Lieberman, we assume that this evidence was not
excluded by the district court under Daubert or Baughman. Even so,
the district court's grant of summary judgment was not in error. Dr.
Lieberman testified that Goewey's injury was "most probably" caused
by "an exposure of chlorinated hydrocarbons coming from asphalt
and the possibility of contamination also with chlorinated hydrocar-
bons that were coming from pesticide which was in the soil," Lieber-
man Deposition at 16.1 Although Dr. Lieberman's testimony is at
times difficult to follow, he apparently believes that either toulene, a
chemical in asphalt, or chlordane, a pesticide, caused Goewey's
injury. J.A. at 486. Goewey has abandoned the theory that chlordane
exposure caused his injury. See J.A. at 149 n.5. And regarding the
asphalt theory of causation, we cannot say that the district court erred
in granting summary judgment in favor of FD. Other than Dr. Lieber-
man's own assertions, we are unable to locate any evidence in the
record to support this theory, and Goewey has pointed to none. Fur-
thermore, at least two of Goewey's own experts have rejected the pos-

neurology, he was board-certified only in pediatrics. J.A. at 476-77.

Conclusion

For the reasons stated herein, we affirm the judgment of the district
court.

AFFIRMED

BUTZNER, Senior Circuit Judge, concurring in part and dissenting
in part:

I concur in the affirmance of the judgment dismissing the United
States. I dissent from the summary judgment in favor of Fluor Daniel,
Inc., and its subsidiary on the issue of medical causation. I am per-
suaded that Dr. Allan Lieberman's testimony is admissible and that
it presents a genuine issue of material fact.

In Daubert v. Merrill Dow Pharmaceuticals, 

(1993),
the Supreme Court restated the rules of admissibility of expert testi-
mony. Previously in most circuits expert testimony was only admissi-
ble if it was based upon theories or techniques that had gained
"general acceptance" in the relevant scientific field. Frye v. United
States, 

, 47, 

, 1014 (1923). Daubert held
that the "austere standard" of the Frye test had been displaced by the
Federal Rules of Evidence, 

. Consequently,
courts may admit expert testimony if it meets a two-prong test for
_________________________________________________________________
2 Goewey also argues that the district court erred in denying his motion
to inspect the property on which he had been exposed to the roof sealant
in order to collect a sample of the sealant. We disagree. As the district
court noted, Goewey's failure to file this motion until two months after
he learned that no current sample of the sealant existed, one month after
the date that the district court had set as the cut-off date for discovery,
and one week after the government and FD filed their motions to dismiss
and for summary judgment, provided a sufficient basis to deny Goewey's
motion. Alternatively, as the district court noted, any potential sampling
of the roof sealant, taken now five years after Goewey's exposure to it,
would be "inherently suspect," J.A. at 170.

                    7
reliability and relevance. 

generally United States v.
Dorsey, 

, 813-14 (4th Cir. 1996).

The tests for reliability and relevance derive from Rule 702 of the
Federal Rules of Evidence. Rule 702 permits an expert to testify to
any "scientific, technical or other specialized knowledge that will
assist the trier of fact to understand the evidence or to determine a fact
in issue." An expert's testimony is reliable if it is based on "scientific
knowledge"--a body of facts or inferences which are "grounded in
the methods and procedures of science." 

respect to the second prong, relevancy, the Supreme Court
adopted the definition stated in Rule 401, which provides that relevant
evidence is that which has "`any tendency to make the existence of
any fact that is of consequence to the determination of the action more
probable or less probable than it would be without the evidence.' Rule
401. The Rules' basic standard of relevance thus is a liberal one." 

the testimony must not run afoul of Rule 403,
which cautions against evidence that misleads the jury through unfair
prejudice or confusion of the issues. 

substance of the
expert's testimony "requires a valid scientific connection to the perti-
nent inquiry as a precondition to admissibility." 

encourages courts to consider a variety of factors in
assessing whether an expert's testimony is scientifically reliable and
relevant. These factors include whether the expert's scientific theory
or technique has been tested, peer-reviewed, or published, as well as
its applicable rate of error. 

may also consider
whether the scientific method meets Frye's standard of "general
acceptance" in the particular scientific field. 

how-
ever, emphasized that these factors should only provide general guid-
ance to lower courts and should not serve as a definitive checklist that
courts must follow. 

Lieberman's testimony satisfied Daubert's twin touchstones of
reliability and relevance. Dr. Lieberman is a board certified pediatri-
cian who practices occupational and environmental medicine. He also
has extensive clinical experience in pediatric neurology. For five
years, Dr. Lieberman served as medical director of the Vince Mosley
Diagnostic and Evaluation Clinic of Charleston, South Carolina,

                     8
which is the center for the diagnosis of neurologically handicapped
children. He was also medical director of the Coastal Rehabilitation
Center in Charleston, a state institution which serves neurologically
handicapped children and adults. He served as Chief of Pediatrics at
the United States Naval Hospital in Charleston, South Carolina, and
he was a lecturer in applied neuroanatomy at the Medical University
of South Carolina. In addition to being board certified in pediatrics,
he is a Fellow, American Academy of Environmental Medicine, and
a Diplomat, American Board of Environmental Medicine. There can
be no doubt that Dr. Lieberman was well qualified to testify about the
neurological consequences of Stephen Goewey's exposure to the tar
or asphalt that Fluor Daniel applied to the Goewey residence.

Dr. Lieberman's method of diagnosis was scientifically reliable. He
diagnosed Stephen's condition using differential diagnosis. The Fed-
eral Judicial Center's Reference Manual on Scientific Evidence, 214
(West 1994), defines differential diagnosis as follows:

          The method by which a physician determines what disease
          process has caused a patient's symptoms. The physician
          considers all relevant potential causes of the symptoms and
          then eliminates alternative causes based on a physical exam-
          ination, clinical tests, and a thorough case history.

See also Dorland's Illustrated Medical Dictionary 369 (6th Ed.
1985). Differential diagnosis is a well-recognized, reliable method of
medical diagnosis that has gained "widespread acceptance" in the
medical community. It has been subject to peer review and "does not
frequently lead to incorrect results, it is a method that involves assess-
ing causation with respect to a particular individual." In re Paoli R.R.
Yard PCB Litigation, 

, 758 (3d Cir. 1994). Stephen was
one of Dr. Lieberman's patients. Dr. Lieberman based his diagnosis
on examinations, clinical tests, and a thorough case history. Dr. Lie-
berman's differential diagnosis satisfied Daubert's requirement that
an expert's testimony must be reliable.

Dr. Lieberman's testimony also satisfies Daubert 's second require-
ment that an expert's testimony must be relevant. It is undisputed that
Stephen was exposed to the tar that Fluor Daniel applied to the family
residence. The evidence discloses that 80% of the child's body was

                     9
covered with tar. He had tar on his hands and under his fingernails.
While his mother was trying unsuccessfully to wash the tar off, he
kept putting his hands in his mouth with such frequency that a navy
employee suggested that Stephen's mother should hold his hands
down. His teeth were coated with tar, and the day after his initial
exposure to the tar he still had tar on his teeth, fingernails, toenails,
and eyebrows. Before exposure, he was a normal child. After expo-
sure, he suffered severe neurological deficits.

Dr. Lieberman found biomarkers in Stephen for toluene, a neuro-
toxic petroleum solvent contained in tar or asphalt that can cause
long-term toxicity. A urinalysis of Stephen at Duke University
revealed high levels of hippuric acid, the major metabolite and bio-
marker for toluene. Though there was no evidence of toluene in Ste-
phen's fat samples, Dr. Lieberman explained that he would not expect
to see evidence of toluene 14 months after the incident in a substance
as nonhomogeneous as fat. Evidence of toluene in fat would have
confirmed the diagnosis, but the absence of such evidence did not rule
out the presence of toluene. Specifically, the doctor reasoned: "[I] feel
at this time that we do have biological markers of exposure with hip-
puric acid from the toluene and the sample taken at the Medical Uni-
versity for the oxychlordane [pesticide]. So I'm perfectly satisfied."
(bracket added).

Dr. Lieberman explained in detail why he believed that Stephen
was not suffering from genetic deficiencies. He testified that Stephen
suffers from brain damage. With respect to causation, he concluded:
"[T]he causation was most probably related to an exposure of chlori-
nated hydrocarbons coming from asphalt and the possibility of con-
tamination also with chlorinated hydrocarbons that were coming from
pesticide which was in the soil." In South Carolina, an expert testify-
ing to causation must state that the data on which he bases his conclu-
sion most probably caused the injury. Baughman v. American Tel. &
Telegraph, 

, 111, 

, 543 (1991). Dr. Lie-
berman's expert testimony about the toluene in the tar satisfies South
Carolina's "most probably" requirement of causation.

Fluor Daniel did not apply the pesticide. But Dr. Lieberman's opin-
ion that the tar and the pesticide caused Stephen's injury does not pre-
clude the admissibility of his testimony. Nor does it defeat Stephen's

                     10
claim. The Supreme Court of South Carolina recognizes concurring
causes. In a passage that is clear and to the point, the Court wrote:

           When we speak of proximate cause, we are not referring
          to the "sole cause." In order to establish actionable negli-
          gence, the plaintiff is required only to prove that the negli-
          gence on the part of the defendant was at least one of the
          proximate, concurring causes of his injury. It is generally for
          the jury to say whether the defendant's negligence was a
          concurring, proximate cause of the plaintiff's injuries.

Hughes v. Children's Clinic, P. A., 

, 398, 

, 757 (1977).

Fluor Daniel emphasizes that plaintiff's experts disagree. But this
does not compel dismissal of the plaintiff's case. Federal Rule of
Civil Procedure 8 permits a plaintiff to state as many separate claims
as the party has "regardless of consistency." The need to state multi-
ple claims is particularly pressing in the discovery phase when a
plaintiff needs to explore all possibilities in a case such as this. The
need was aggravated because the government lost or misplaced the
only sample of the tar that was taken shortly after Stephen's exposure.
Fortunately the loss of the sample is not fatal. Stephen's urinalysis at
Duke established the presence of a toxic constituent of tar or asphalt
in his body. In any event, the Supreme Court has put Fluor Daniel's
defense on this issue to rest. The Court has held that medical unanim-
ity is not required among the plaintiff's experts for a jury to draw its
own causal conclusions and that experts may testify that there was
more than one potential cause of the plaintiff's injuries. Sentilles v.
Inter-Caribbean Shipping Corp., 

, 109 (1959); see also
Hines v. Consolidated Rail Corp., 

, 269 (3d Cir. 1991).

Summary judgment is appropriate only when there exists no genu-
ine issue of material fact in dispute. Fed. R. Civ. P. 56(c). To survive
summary judgment, a plaintiff must forecast sufficient evidence sup-
porting his version of a disputed material fact so that a reasonable jury
could return a verdict in his favor. Anderson v. Liberty Lobby Inc.,

, 250. Anderson defines the sufficiency of the evidence
standard as "whether the evidence presents a sufficient disagreement

                    11
to require submission to a jury or whether it is so one-sided that one
party must prevail as a matter of law." Anderson, 

, 251.

The cause of Stephen's injury is, of course, a material fact. Ste-
phen's evidence is sufficient to enable a reasonable jury to return a
verdict in his favor.

The trial court has not yet ruled on the admissibility of the Fluor
Daniel's experts' opinions, so it would be superfluous to analyze
these opinions in detail. Suffice it to say that the substance of their
testimony is that they do not know the cause of Stephen's condition,
in their terms "etiology unknown."

Clearly there is a genuine issue of material fact that made summary
judgment inappropriate. I respectfully dissent because Stephen is enti-
tled to a jury trial.
