OPINION
I. INTRODUCTION
Property owners filed suit alleging injuries to real property caused by petroleum contamination. The superior court dismissed the negligence and strict liability claims, on the ground they were barred by the two-year statute of limitations, AS 09.10.070. Because we conclude that these claims alleged “trespass upon real property” and were subject to the six-year statute of limitations, AS 09.10.050(2), we reverse and remand.
II. FACTS AND PROCEEDINGS
Sam E. McDowell and A. Joyce McDowell own certain real property in Sterling. 1 Thomas L. Edwards and Rayme Gardner Edwards formerly owned real property in Sterling. John E. Cook and Carol A. Cook, and C & R Enterprises d/b/a Sterling Tesoro Service Station (Cooks) own and operate a service station near the McDowell and former Edwards properties. At some time, or over a period of time, petroleum spilled or leaked at the service station. The State of Alaska became involved in the remediation and cleanup of the spill or leakage. The *967 McDowells and the Edwardses (collectively McDowells) learned that there was contaminant migration from the service station, across the State highway, and onto then-properties.
The McDowells filed a complaint against the Cooks, Tesoro Alaska Petroleum Company (Tesoro), and the State of Alaska. They alleged various causes of action in a complaint that they now claim asserted “primarily economic injuries as a result of the damage to and consequential restricted use and lowered value of their real property.” 2 Count One claimed that Tesoro and the Cooks negligently breached their duty to operate their petroleum business so as not to damage the McDowells’ property, and that this breach proximately caused the McDo-wells to suffer damages. Count Two claimed that the State of Alaska negligently breached the duty of conducting remediation and clean-up without damaging the McDowells’ property, and that this breach proximately caused the McDowells to suffer damages. Count Three claimed that Tesoro and the Cooks were strictly liable in tort for the escape and migration of petroleum products that contaminated the McDowells’ property.
The defendants sought summary judgment on the ground that the. tort claims were barred by the two-year statute of limitations, AS 09.10.070. The superior court granted partial summary judgment for the defendants, dismissing the McDowells’ negligence and strict liability tort claims asserted in the first three counts of the complaint.
The McDowells filed a petition for review seeking reversal of the superior court’s dismissal of their claims. We granted then-petition in order to review the issue of the applicable period of limitations for negligence and strict liability actions that allege injury to real property.
III. DISCUSSION
We must decide whether the six-year statute of limitations (AS 09.10.050) or the two-year statute of limitations (AS 09.10.070) applies to the McDowells’ strict liability and negligence claims. 3
The McDowells characterize then-negligence and strict liability claims as “claim[s] for damages resulting from trespass to real property.” They contend that damage to property sounds in “trespass” for purposes of AS 09.10.050(2), regardless of whether the property was harmed negligently or intentionally. Because their claims sound in trespass, they argue, this is an action for “trespass upon real property” and is therefore governed by AS 09.10.050(2). *968 We agree. 4
In determining which statute of limitations applies, we look to the nature of the injury alleged, rather than to the technical cause of action.
5
See, e.g., Breck v. Moore,
Our conclusion that the McDowells’ claims sound in trespass is consistent with the results reached in other cases, which have held that negligent contamination of real property is an injury to land in the nature of trespass.
See, e.g., Sterling v. Velsicol Chem. Corp.,
This conclusion is also consistent with previous statements by this court to the effect that tortious injury to real property is governed by AS 09.10.050(2). In
McKibben v. Mohawk Oil Co.,
The State, Tesoro, and the Cooks argue that the McDowells’ claims are really actions for “trespass on the case” that sound in tort and are therefore governed by AS 09.10.070. 7 They contend that the word “trespass” as used in AS 09.10.050(2) is a technical term, and therefore does not apply to the McDo-wells’ claims. We disagree.
As an initial matter, the harm alleged in the McDowells’ negligence and strict liability claims may be characterized as a direct invasion of their property rights. To the extent that “trespass on the ease” implies an indirect invasion, the McDowells’ action is not for “trespass on the case.”
See Martin,
More importantly, AS 09.10.050(2) does not necessarily distinguish between “trespass” and “trespass on the case.” The historical origins of the words “trespass” and “trespass on the case” do not foreclose a conclusion that AS 09.10.050(2) encompasses negligence and strict liability actions based on injury to real property.
8
As the Oregon
*970
Supreme Court has noted, “[t]he distinction between direct and indirect invasions where there has been a physical invasion upon the plaintiffs land has been abandoned by some courts.”.
Martin,
The goal of statutory construction is to give effect to the legislature’s intent, with due regard for the meaning the statutory language conveys to others. In this respect, we have repeatedly stated that unless words have acquired a peculiar meaning, by virtue of statutory definition or judicial construction, they are to be construed in accordance with their common usage.
The term “trespass” is not defined by the statutes of limitations, nor have we had occasion to examine whether the term “trespass” as used in AS 09.10.050(2) reaches underground contamination that invades the rights of a property owner. Thus, the plain or common meaning of the term “trespass” is controlling. See id.
According to its common usage, the term “trespass” encompasses the property invasions alleged by the McDowells in Counts One, Two, and Three. These counts each allege that the defendants’ actions interfered with the McDowells’ exclusive possession of their property.
9
This description of the harm alleged fits the common usage of the term “trespass.”
See Webster’s II New Riverside University Dictionary
1231-32 (1994) (defining trespass as an invasion of “property, rights, or person of another without his or her consent and with the actual or implied commission of violence, especially to enter onto another’s land illegally”);
Black’s Law Dictionary
1502 (6th ed.1990) (defining trespass as “[a]n unlawful interference with one’s person, property, or rights”). As noted above, we interpret the limitations statutes in terms of the nature of the injury rather than the technical cause of action.
See, e.g., Breck,
*971
Finally, other considerations support application of AS 09.10.050 rather than AS 09.10.070 to the McDowells’ claims. First, the defense of the statute of limitations is a legitimate, but disfavored, defense. We therefore have expressed a policy of applying the longer of two limitations periods if two limitations statutes apply to a claim.
See, e.g., Lee Houston,
Second, policy reasons support selection of a longer statute of limitations for actions alleging negligent injury to real property. For example, an action alleging economic injuries caused by negligent damage to real property is likely to involve “documentary evidence” which remains rehable after the passage of time. 11 These policy reasons support application of AS 09.10.050(2) to the McDowells’ negligence and strict liability claims.
IV. CONCLUSION
Because the first three counts of the McDowells’ complaint expressly pled an invasion of property rights that would be a “trespass upon real property,” those counts are subject to the six-year limitations period of AS 09.10.050(2). We therefore REVERSE the order granting summary judgment to the defendants, and REMAND with instructions to reinstate the McDowells’ action with respect to those three counts.
Notes
. Because we are reviewing a partial summary judgment on a limitations issue, allegations about the petitioners' ownership of the property and the fact and source of contamination are accepted for purposes of discussion.
. Only Counts One, Two, and Three of the complaint are at issue. The McDowells' complaint also alleged claims for trespass, nuisance, breach of duty to disclose (State only), and breach of contract (State only), and sought punitive damages (Tesoro and Cooks only), and compensatory damages applicable to all counts.
. The limitations statutes were revised in 1997. As this action accrued prior to 1997, we apply the pre-amendment statutes. As it read at the pertinent time, AS 09.10.050 provided:
Unless the action is commenced within six years, a person may not bring an action
(1) upon a contract or liability, express or implied, excepting those mentioned in AS 09.10.040; (2) for waste or trespass upon real property; or (3) for taking, detaining, or injuring personal property, including an action for its specific recovery.
Former AS 09.10.050 (emphasis added). As amended in 1997, AS 09.10.050 now states in its entirety, "Unless the action is commenced within six years, a person may not bring an action for waste or trespass upon real property.”
AS 09.10.070(a) provided:
A person may not bring an action
(1) for libel, slander, assault, battery, seduction, false imprisonment, or for any injury to the person or rights of another not arising on contract and not specifically provided otherwise; (2) upon a statute for a forfeiture or penalty to the state; or (3) upon a liability created by statute, other than a penalty or forfeiture; unless commenced within- two years.
Former AS 09.10.070(a). As amended in 1997, the pertinent part of AS 09.10.070 now states:
(a) Except as otherwise provided by law, a person may not bring an action (1) for libel, slander, assault, battery, seduction, or false imprisonment!);] (2) for personal injury or death, or injury to the rights of another not arising on contract and not specifically provided otherwise; (3) for taking, detaining, or injuring personal property, including an action for its specific recovery ... unless the action is commenced within two years of the accrual of the cause of action.
. We exercise our independent judgment when interpreting and applying statutes of limitations.
See Pedersen v. Flannery,
"In interpreting any statute, 'our primary guide is the language used, construed in light of the purpose of the enactment.’ "
Alaska Horn. Fin. Corp. v. Salvucci,
. In this regard, our statute of limitations jurisprudence has evolved over the last twenty years. In
Van Horn Lodge,
we held that the limitation period depends on whether the gravamen of the plaintiff’s complaint lies in tort or contract.

W. Page Keeton et al.,
Prosser and Keeton on the Law of Torts
§ 13, at 67 (5th ed. 1984) ("Historically, the requirements for recovery for trespass to land under the common law action of trespass were an invasion (a) which interfered with the right of exclusive possession of the land, and (b) which was the direct result of some act committed by the defendant.”);
Restatement (Second) of Torts
§ 165 (1986) cmt. c (stating that one who recklessly or negligently causes a person or thing to enter another’s land is liable for trespass if the presence of the person or thing causes harm to the possessor's land or to a thing in whose security the possessor has a legally protected interest).
See also Wernberg v. Matanuska Elec. Ass’n,
. The historical distinction between trespass and trespass on the case has been articulated as follows:
Trespass was the remedy for all forcible, direct and immediate injuries, whether to person or to property.... Trespass on the case, or the action on the case, as it came to be called, developed somewhat later, as a supplement to the parent action of trespass, designed to afford a remedy for obviously wrongful conduct resulting in injuries which were not forcible or not direct. The distinction between the two lay in the immediate application of force 'as to the person or property of the plaintiff, as distinguished from injury through some obvious and visible secondary cause.... The distinction was not one between intentional and negligent conduct. The emphasis was upon the causal sequence, rather than the character of the defendant’s wrong. Trespass would lie for all direct injuries, even though they were not intended, and the action on the case might be maintained for those which were intended but indirect.
Keeton, supra note 6, § 6, at 29-30.
. We have recognized the distinction between "trespass" and "action on the case”’ in previous cases.
See, e.g., Kodiak Elec. Ass’n, Inc. v. DeLaval Turbine, Inc.,
The limited nature of this holding should be recognized. Our decision goes only to the question of which statute of limitations applies. Although we hold that the McDowells’ negligence and strict liability claims are subject to AS 09.10.050(2) because they sound in "trespass,” the McDowells must still show the distinct elements necessary to prove their negligence, strict liability, and trespass claims on the merits. Because this case is before us on summary judgment, the parties have briefed only the statute of limitations issue. We are not being asked to decide whether contamination resulting from unintentional acts would satisfy the elements of a trespass claim. The battle over the appropriate statute of limitations need not be coextensive with a battle on the merits.
. The counts allege that Tesoro and the Cooks failed to maintain their fuel lines and storage tanks so that they would not leak and damage the McDowells’ property (Count One); that the State failed to conduct the remediation so as not to damage the McDowells' property (Count Two); and that Tesoro and the Cooks are strictly liable for the damages caused by the escape of the petroleum products (Count III).
Count II, which alleges that the State negligently failed to prevent the contamination from reaching the McDowells’ property, is a trespass claim because the result of the State’s omission was a physical invasion. Whether the State owed a duty to prevent the contamination from reaching the McDowells' property is a separate issue that does not resolve how the limitations issue must be decided.
See Restatement (Second) of Torts
ch. 7, at 276 (1965) (stating that " '[trespass [ ] on land’ ... includes not only entries on land resulting directly or indirectly from the actor's act, but also the presence on the land of a thing which it is the actor’s duty to remove”);
see also River Valley Assoc. v. Consol. Rail,
.
Cf. Commonwealth, Dep't of Highways v. Ratliff,
. As this court stated in Lee Houston:
[Applying a longer statute of limitations] to claims ... involving economic loss is consistent with the primary purpose of the statutes of limitations. The statutes are intended to encourage prompt prosecution of claims and thus avoid injustices which may result from lost evidence, faded memories and disappearing witnesses. Actions ... involving economic loss are often based largely on documentary evidence^] not unaided recollections which quickly grow stale. On the other hand, a shorter limitations period is consistent with the more evanescent nature of evidence which is frequently found in cases involving personal, reputational or dignitary injuries.
