OPINION
HOLLIS HORTON, Justice.
This case involves a nonhazardous, wastewater injection well operated by Environmental *741 Processing Systems, L.C. ("EPS") and located near two tracts of land owned by FPL Farming Ltd. ("FPL"). FPL sued EPS, and the case was tried before a jury, which found against FPL on all of its submitted causes of action: trespass, negligence, and unjust enrichment. On appeal, FPL raises four issues: (1) the trial court improperly denied FPL's motion for a directed verdict, (2) the jury charge's instructions on trespass misplaced the burden of proving lack of consent, (3) the charge erroneously failed to instruct the jury that injury is not a necessary element of trespass, and (4) the evidence supporting the jury's verdict is factually insufficient. Because we find that an actionable trespass, under the circumstances presented here, did not occur, and that the evidence is factually sufficient to support the jury's verdict, we affirm.

I. Background
In 1996, the Texas Natural Resource Conservation Commission[1] ("Commission") granted permits to EPS for construction in Liberty County of two wells that would inject commercial, nonhazardous industrial waste approximately 7,350 to 8,200 feet below the surface into the Frio saltwater formation. FPL Farming, Ltd. v. Texas Natural Resource Conservation Com'n, No. 03-02-00477-CV, 2003 WL 247183, at *1 (Tex.App.-Austin Feb. 6, 2003, pet. denied). The proposed wells were to be located near two tracts of land owned by FPL. Id.
Under Commission rules, an injection well permit application must contain ten-year and thirty-year projections that predict how far the injected material will migrate from a well. Id. After receiving notice of EPS's applications and learning that the underground waste plume from the proposed wells was projected to reach the subsurface of its closer property within ten years, FPL requested a contested case hearing in 1996 to oppose the permit applications. Id. Ultimately, FPL settled with EPS for $185,000 "to avoid the delay and the expense of a hearing." Id. FPL then withdrew its hearing request, and the Commission granted the permits. Id.
In 1999, when EPS sought to amend its permits to increase the allowed injection rate, FPL requested and received a contested case hearing. Id. The administrative law judge ("ALJ") who presided at the hearing and another ALJ who read the record recommended that the Commission grant the amendments. Id. The ALJs also proposed certain findings of fact and conclusions of law, including: (1) the waste plume would radiate 3,021 feet from the well facility after ten years, assuming the maximum injection rate; (2) FPL had no absolute right to exclude others from the deep subsurface below its property; (3) FPL did not own the oil and gas mineral interests associated with the land in question; (4) FPL's existing rights would not be impaired by the amended permits; and (5) operation of the wells under the amended permits would not be an unconstitutional taking. Id. The Commission adopted the ALJs' findings of fact and conclusions of law and granted EPS's application for the amended permits. Id.
FPL appealed the Commission's order to the Travis County district court, which affirmed the agency's decision. Id. at *2. On appeal to the Austin Court of Appeals, FPL contended: (1) the Commission exceeded its statutory authority by granting the amended permit when it knew the *742 waste plume from EPS's well would migrate into the deep subsurface of FPL's property, and (2) the grant of the amended permits allowed a permanent physical invasion of FPL's property and was an unconstitutional taking. Id. In 2003, the Austin Court of Appeals affirmed the district court's judgment. Id. at *1. The Austin Court assumed, but did not decide, that FPL had "existing rights" in the deep subsurface beneath its land and further noted that if the waste plume migrated to the subsurface of FPL's property and caused harm, FPL could seek damages from EPS. Id. at **3, 5 (citing TEX. WATER CODE ANN. § 27.104 (Vernon 2000)).[2]
In 2006, FPL sued EPS in Liberty County seeking injunctive relief and alleging various causes of action, including trespass, unjust enrichment, and negligence. The jury rejected FPL's claims for trespass, unjust enrichment, and negligence, which constituted all of the theories pled by FPL that were submitted to the jury. FPL then timely filed its notice of appeal.

II. Trespass
Three of FPL's four issuesone, two, and threecomplain of errors related to FPL's trespass claim. Issue one contends the trial court should have granted FPL a directed verdict on consent. Issue two asserts the jury charge erroneously required FPL to prove that it had not consented. Issue three argues the trial court erred by failing to instruct the jury that injury is not a necessary element of trespass.
FPL maintains that "[t]he question in this case is whether FPL Farming owns the portion of the Frio formation beneath its land and the groundwater the formation contains." FPL also argues that "[t]he Texas Water Code expressly recognizes that landowners own the groundwater beneath their property." See TEX. WATER CODE ANN. § 36.002 (Vernon 2008).[3]
EPS contends that the trial court's judgment that FPL take nothing is proper because there is no established cause of action to complain about deep subsurface migration of injected fluids. EPS further argues that its activities pose no threat to or effect upon any neighboring surface, subsoil, or percolating groundwater.
As an initial matter, we must consider whether FPL has a trespass claim when the facts demonstrate that the Commission approved an amended permit allowing EPS to inject wastewater into the Frio formation and when information before the Commission showed that EPS's waste plume was projected to migrate into the deep subsurface of the formation underlying FPL's property. As to claims alleging a subsurface trespass, the Texas Supreme Court recently explained:
[F]rom the ancient common law maxim that land ownership extends to the sky above and the earth's center below, one might extrapolate that the same rule *743 should apply two miles below the surface. But that maximcujus est solum ejus est usque ad coelum et ad inferos "has no place in the modern world." Wheeling an airplane across the surface of one's property without permission is a trespass; flying the plane through the airspace two miles above the property is not. Lord Coke, who pronounced the maxim, did not consider the possibility of airplanes. But neither did he imagine oil wells. The law of trespass need no more be the same two miles below the surface than two miles above.
Coastal Oil & Gas Corp. v. Garza Energy Trust, 268 S.W.3d 1, 11 (Tex.2008) (quoting United States v. Causby, 328 U.S. 256, 260-61 & n. 5, 66 S.Ct. 1062, 90 L.Ed. 1206 (1946)) (footnotes omitted).
Significantly, the Garza Court recognized the import of a state agency's authorization of competing uses of land by reiterating the precedential value of Railroad Commission of Texas v. Manziel, 361 S.W.2d 560, 568-69 (Tex.1962). Garza, 268 S.W.3d at 12. In Manziel, the Court concluded that a secondary recovery operation involving the subsurface injection of salt water did not cause a trespass when the water migrated across property lines, in light of the Railroad Commission's approval of the operation. Manziel, 361 S.W.2d at 568-69. The Garza Court also observed that thirty years after Manziel, the Texas Supreme Court had decided Geo Viking, Inc. v. Tex-Lee Operating Company and had concluded that a subsurface operation causing fractures in formations underneath another's land was a trespass. Garza, 268 S.W.3d at 12 (citing Geo Viking, Inc. v. Tex-Lee Operating Co., 839 S.W.2d 797 (Tex.1992) (per curiam op. withdrawn on reh'g)). However, the Garza Court explained that the original Geo Viking opinion was withdrawn on rehearing and that the Geo Viking Court's opinion issued on rehearing expressly did not decide the trespass issue. Id. (citing Geo Viking, 839 S.W.2d at 798).[4]Manziel, thus, has not been overruled, and we conclude that the facts presented there are analogous to those in the case before us.
In Manziel, the Texas Supreme Court explained:
The subsurface invasion of adjoining mineral estates by injected salt water of a secondary recovery project is to be expected, and in the case at bar we are not confronted with the tort aspects of such practices. Neither is the question raised as to whether the Commission's authorization of such operations throws a protective cloak around the injecting operator who might otherwise be subjected to the risks of liability for actual damages to the adjoining property; rather we are faced with an issue of whether a trespass is committed when secondary recovery waters from an authorized secondary recovery project cross lease lines.
Manziel, 361 S.W.2d at 566-67.
The Manziel Court considered public policy reasons as well as societal and industry interests in making its determination:
The orthodox rules and principles applied by the courts as regards surface invasions of land may not be appropriately applied to subsurface invasions as arise out of the secondary recovery of natural resources. If the intrusions of salt water are to be regarded as trespassory *744 in character, then under common notions of surface invasions, the justifying public policy considerations behind secondary recovery operations could not be reached in considering the validity and reasonableness of such operations. See: Keeton and Jones: `Tort Liability and the Oil and Gas Industry II,' 39 Tex. Law Rev. 253 at p. 268. Certainly, it is relevant to consider and weigh the interests of society and the oil and gas industry as a whole against the interests of the individual operator who is damaged; and if the authorized activities in an adjoining secondary recovery unit are found to be based on some substantial, justifying occasion, then this court should sustain their validity.
Id. at 568.
Explaining that the rules of trespass were "technical" and should not affect the validity of the Railroad Commission's orders, the Manziel Court held:
We conclude that if, in the valid exercise of its authority to prevent waste, protect correlative rights, or in the exercise of other powers within its jurisdiction, the Commission authorizes secondary recovery projects, a trespass does not occur when the injected, secondary recovery forces move across lease lines, and the operations are not subject to an injunction on that basis.
Id. at 568-69. As the Garza Court noted, the Manziel decision "relied heavily on the fact that the [Railroad] Commission had approved the operation." Garza, 268 S.W.3d at 12.[5]
In this case, EPS obtained the approval of the Texas Natural Resource Conservation Commission[6] for its wastewater injection well. FPL Farming, 2003 WL 247183, at *1. Pursuant to Chapter 27 ("Injection Wells") of the Texas Water Code, the Commission is authorized to issue permits for injection wells and is charged with doing so "for the benefit of the state and the preservation of its natural resources." TEX. WATER CODE ANN. §§ 27.011-.012 (Vernon 2008). The policies and purposes of the Injection Well Act are stated in section 27.003:
It is the policy of this state and the purpose of this chapter to maintain the quality of fresh water in the state to the extent consistent with the public health and welfare and the operation of existing industries, taking into consideration the economic development of the state, to prevent underground injection that may pollute fresh water, and to require the use of all reasonable methods to implement this policy.
Id. §§ 27.001, 27.003.
Thus, just as the Railroad Commission considered both public and private interests in allowing the subsurface injection of salt water as described by the Texas Supreme Court in Manziel, the Commission in this case also was required to consider various interests. The doctrine of common law trespass is only one of the factors that it might consider. Based on the reasoning applied by the Texas Supreme Court in Manziel, we conclude that under the common law, when a state agency has authorized deep subsurface injections, *745 no trespass occurs when fluids that were injected at deep levels are then alleged to have later migrated at those deep levels into the deep subsurface of nearby tracts. Because we conclude that no actionable common law trespass has occurred, we overrule issues one, two, and three.

III. Issue Four
In issue four, FPL contends the jury's findings rejecting its claims for trespass, negligence, and unjust enrichment are against the great weight and preponderance of the evidence. Because we hold that no actionable trespass occurred under the circumstances presented in this case, FPL's argument in issue four with respect to trespass is moot. See generally TEX.R.APP. P. 47.1.
We next consider FPL's argument that the evidence is factually insufficient to support the jury's adverse finding on unjust enrichment. In a jury trial, a complaint that the evidence is factually insufficient must be raised in a motion for new trial in order to preserve the complaint for appellate review. TEX.R. CIV. P. 324(b)(2). FPL's motion for new trial, however, did not assert that the jury's finding on unjust enrichment was supported by factually insufficient evidence. Because FPL failed to preserve this complaint for our review, we do not consider FPL's factual sufficiency argument to the extent FPL now, for the first time, seeks to challenge the jury's unjust enrichment finding. See id.
For purposes of appeal, FPL did perfect its claim that the jury's rejection of its claim of negligence was against the greater weight and preponderance of the evidence. When, as is the case here, an appellant challenges the factual sufficiency of the evidence supporting an adverse finding on an issue for which he had the burden of proof, the appellant must show "the adverse finding is against the great weight and preponderance of the evidence." Dow Chem. Co. v. Francis, 46 S.W.3d 237, 242 (Tex.2001).
To prevail on its negligence claim, FPL had to prove the existence of a legal duty, a breach of that duty, and damages proximately caused by the breach. See D. Houston, Inc. v. Love, 92 S.W.3d 450, 454 (Tex.2002). Thus, among the other elements of its negligence cause of action, FPL had to show it was injured by EPS's actions. See generally A.B.F. Freight Sys., Inc. v. Austrian Import Serv., Inc., 798 S.W.2d 606, 615 (Tex.App.-Dallas 1990, writ denied) (recognizing that establishing the fact of damage is a prerequisite to establishing the amount of damages to be awarded). FPL's brief, however does not explain how the greater weight and preponderance of the evidence proved that it was injured.
In addition, FPL did not request that an issue on injury be submitted to the jury. Further, prior to judgment, FPL did not ask the trial court to make any findings of fact or conclusions of law. See TEX.R. CIV. P. 279 (providing in part that when one or more elements of a ground of recovery are omitted from the charge, and there is factually sufficient evidence to support a finding thereon, the trial court, at the request of either party before judgment is rendered, may make written findings on such omitted element).
Because injury was an element omitted from the jury charge, and no request was made to include it, no objection was made to its exclusion, and no written findings were made by the trial court, we must deem that the omitted element on the question of injury was found by the trial court in a manner that supports the judgment. See TEX.R. CIV. P. 279 (providing that omitted elements of a claim "shall be deemed found by the court in such manner as to support the judgment"); Tri v. *746 J.T.T., 162 S.W.3d 552, 558 (Tex.2005).[7] Therefore, there is an implied finding that EPS did not cause an injury to FPL. See TEX.R. CIV. P. 279.
In this case, the evidence reveals that the question of whether FPL had been injured was one of the central issues in the parties' dispute. Even if we were to assume for purposes of argument that FPL proved duty and breach of duty, the great weight and preponderance of the evidence does not show that FPL suffered injury as a result of EPS's injections of waste at a deep level on its own property even if the waste had migrated at those deep levels to neighboring tracts. FPL's corporate representative testified that the "highest and best use" for the property was as a rice field, the way it was being used. FPL does not contend that EPS's actions have interfered with FPL's use of the property as a rice field. Further, FPL's expert testified that there is no evidence that the wastewater has migrated to the surface of the property, that EPS's neighbors are not in jeopardy of waste coming into their subsoil or soil, and that the injection well is not a danger to drinking water. FPL's corporate representative testified that FPL had not tried to sell the property. Moreover, FPL argues on appeal that it did not have to show injury to be entitled to recover under its trespass theory, and the actions of EPS underlying FPL's trespass claim are the same ones that are the basis for its negligence claim.
Thus, in its appeal, FPL has failed to demonstrate that the trial court's implied finding rejecting its claim of injury is contrary to the greater weight and preponderance of the evidence. See Francis, 46 S.W.3d at 242. Therefore, to the extent FPL's appeal challenges the factual sufficiency of the evidence to support the judgment rejecting its claim for negligence, its argument on that ground is also overruled.
Having considered and rejected all of FPL's arguments in issue four, we overrule that issue. Having overruled all of FPL's issues, we affirm the trial court's judgment.
AFFIRMED.
