Opinion
—Respondent the Titan Corporation (Titan) owned a plant in New Jersey (hereafter the Keasbey site or Keasbey facility) that had been operating since 1906. When Titan decided to close the plant in 1985, it began investigating the extent of its environmental cleanup responsibilities under a New Jersey statute. The investigation revealed the site had some forms of pollution.
Titan then purchased a policy of insurance from appellant Aetna Casualty and Surety Company (Aetna). The Aetna policy contained, among other provisions, a “pollution exclusion,” which, on first consideration, appears unambiguously to declare that the policy covered neither pollution damages nor cleanup liabilities. Titan nevertheless made a claim on the policy for the costs of cleaning up the Keasbey facility. Aetna denied the claim.
After trial the court below made factual and legal findings which had the net effect of declaring Aetna liable for part of the cleanup costs. On appeal, we are asked to review the policy and its exclusions, and to determine whether the evidence, viewed most favorably in support of the judgment, supports the conclusion the policy applied to the costs incurred by Titan.
I
Background
A. The Facility
For nearly 80 years Titan and its predecessors produced “soft” ferrite at the Keasbey facility. The ferrite manufacturing process produced, as a by-product, waste streams of ferrite sludge. Titan disposed of waste sludge by allowing it to flow into two “infiltration/percolation” lagoons (the I/P lagoons) 1 under permit from the New Jersey Department of Environmental Protection (NJDEP). Titan also placed on the southeastern portion of the site piles of waste materials (i.e., scrap ferrite, old pallets; empty or partially filled drums, etc.). The waste streams and scrap material were classified as *463 nonhazardous. “Hazardous” wastes were disposed of off site as required by state and federal regulations.
B. The Cleanup
Titan’s decision to close the facility in September 1985 triggered obligations under New Jersey’s Environmental Cleanup Responsibility Act (ECRA). (NJ. Stat. Ann., § 13:1K-6 et seq.) ECRA is a strict liability statute requiring the owner to clean up a facility before transferring the property or ceasing operations. To comply with its obligations, Titan retained Dames & Moore as its environmental consultant to investigate the site, perform the required sampling, and prepare a cleanup plan.
The initial site evaluation, submitted to the NJDEP in October 1985, identified a number of areas of contamination. 2 This October 1985 report did not, however, identify “TCE” contamination or groundwater contamination, nor did it identify the dumped brick, concrete, wood or rubbish as “contaminants” for ECRA cleanup.
Following issuance of the October 1985 report, Titan purchased the Aetna policy, effective February 1986. After issuance of the Aetna policy, Titan discovered the so-called “TCE spill area.” 3 The TCE contamination was first discovered when groundwater sampling during March and April 1986 revealed TCE contamination of the groundwater, leading to the discovery of TCE contamination of the soil.
Additionally, in June 1986 the NJDEP identified as a “deficiency” certain solid waste piles (i.e., the brick and rubble from demolished buildings, ceramic waste, etc.). 4 The NJDEP required removal of this waste as part of the cleanup operation.
*464 The remediation efforts thus entailed cleanup of the I/P lagoons and overflow area, as well as the TCE spill area; removal of the oil storage tanks and excavation of some surrounding soil; excavation of soil along the fuel oil transfer line; soil cleanup around the drum storage area; and cleanup of the solid wastes. Among the areas remediated was a strip of land owned by an adjacent business (the Carborundum land) which had been contaminated by the leaking fuel oil transfer line.
The NJDEP did not require Titan to remediate water below the surface, but it did require preparation of a groundwater remediation contingency plan. Additionally, many of the steps required by the NJDEP (such as cleaning up the TCE, remediation of the I/P lagoons and overflow, cleaning up the oil tank and fuel transfer lines, etc.) represented removal of sources of existing or potential groundwater contaminants.
C. The Policy
Titan made a claim on the Aetna policy for the costs of cleaning up in compliance with the NJDEP requirements at the site. In its letter denying coverage Aetna cited the following reasons for denial: the basic policy terms, the “pollution” exclusion, and the “owned property” exclusion.
The Aetna policy provided for numerous exclusions, two of which are pertinent here. First, its “owned property” exclusion provided:
“This insurance does not apply:
“(k) to property damage to (1) property owned or occupied by or rented to the insured; (2) property used by the insured . . . .”
*465 Second, the policy was modified by an endorsement, known as the “absolute pollution exclusion,” which provided that the insurance would not apply
“(1) to bodily injury or property damage arising out of the actual, alleged or threatened discharge, dispersal, release or escape of pollutants: (a) at or from premises owned, rented or occupied by the named insured; which are at any time transported, handled, stored, treated, disposed of, or processed as waste by or for the named insured ....
“(2) to any loss, cost or expense arising out of any governmental direction or request that the named insured test for, monitor, clean up, remove, contain, treat, detoxify or neutralize pollutants. [¶] Pollutants means any solid, liquid, gaseous or thermal irritant or contaminant, including smoke, vapor, soot, fumes, acids, alkalis, chemicals and waste. Waste includes materials to be recycled, reconditioned or reclaimed.”
D. The Lawsuit
The action began when one of Titan’s insurers, Employers Insurance of Wasau, filed an action seeking a declaration of the various insurers’ duties to pay for the cleanup. Aetna became involved on cross-complaint by Titan. Prior to trial, all but two of the insurers settled with Titan. Only Pacific Indemnity Company and Aetna remained as insurers.
In the first phase of the two-phase trial, a jury determined Titan reasonably spent $890,905.42 on the cleanup, a conclusion not disputed on appeal.
Pacific then settled, leaving only Aetna to litigate phase two of the trial involving the question of whether the policy covered the damages. This phase was tried to the court.
The court first concluded the costs were govemmentally compelled cleanup costs which (under
AIU Ins. Co.
v.
Superior Court
(1990)
The court then ruled that the exclusions were inapplicable. It concluded the pollution exclusion was inapplicable because part of the costs was the removal of solid wastes: the piles of brick, concrete, wood and rubbish. Since the policy defined pollutants as “. . . solid, liquid, gaseous, or thermal irritant[s] or contaminants], including smoke, vapor, soot, fumes, acids, alkalis, chemicals and waste,” and the solid wastes were neither irritants nor contaminants, the court concluded the pollution exclusion did not apply to the costs associated with that portion of the cleanup.
The court also rejected application of the “owned property” exclusion. It pointed to the surface and groundwaters, which qualify as third party property, and which were threatened with or actually contaminated by the I/P lagoons, the TCE spill area, the fuel oil tanks and transfer-line leaks. 6 Perceiving that the costs were incurred to remedy injury to third party property, the court deemed the “owned property exclusion” inapplicable.

Analysis
A. The Dispositive Issue is Whether Aetna’s Policy Covers the Costs Associated With Cleanup of the TCE Spill and Solid Wastes
Aetna raises numerous contentions on appeal. Before turning to the central issues, however, we may narrow our focus by first eliminating aspects not at the core of the trial court’s judgment or of this appeal.
Several of Aetna’s appellate arguments focus on the fact Titan was aware of some of the areas of contamination, and of its ECRA obligations to clean up contamination,
before
the inception of Aetna’s policy. The evidence clearly shows that several problems (i.e., the I/P lagoons and overflow area, the fuel tanks, the fuel-transfer-line leaks) were in fact known to Titan and had manifested before the policy’s inception. Regarding these problems, coverage would be barred under the “manifestation” and “known loss” rules governing insurer’s liabilities. (See, e.g.,
Pines of La Jolla Homeowners Assn.
v.
Industrial Indemnity
(1992)
The trial court’s error is harmless, however, because the court explicitly premised its judgment on the costs to remedy problems which were
not
“known” or “manifest” at the policy’s inception (i.e., the TCE spill and the solid waste disposal), rendering moot its “waiver” finding.
7
Because the trial court found on substantial evidence that the TCE spill and the solid waste disposal were “unknown” prior to Aetna’s policy, and Titan’s notice of the
*468
earlier problems is not equivalent to notice of all problems
(Chu
v.
Canadian Indemnity Co., supra,
We also doubt the viability of Aetna’s argument that the losses were barred as being “expected or intended” from the standpoint of the insured. The trial court found that Titan did not intend or expect to contaminate the site, relying on evidence that Titan handled hazardous materials in accordance with Environmental Protection Agency and NJDEP regulations and that the disposal of sludge into the I/P lagoons was under permit from the NJDEP. Aetna argues, however, that a loss should be deemed intentional if (under an objective standard) the insured knew
or should have known
the loss was a substantially probable consequence of its actions. The “should have known” standard Aetna proffered is without support in California, and the courts in both California and New Jersey have concluded the “expected or intended injury” is not triggered merely because the insured’s “should-have-known” injury would be a likely result of his voluntary act.
8
(See
Chu
v.
Canadian Indemnity Co., supra,
We thus narrow our inquiry to the two central exclusions (i.e., the “pollution” and “property owned” exclusions) and apply them to the costs associated with the TCE spill and the solid waste. We will conclude that except for the strip of adjacent land owned by Carborundum, the only third party property injured was the groundwater. The groundwater contamination, as well as the injury to the Carborundum land, was caused solely by the impact of pollutants. Water contamination from the TCE, the spilled fuel oil, and/or the fine grain metals (i.e., ferrite, zinc oxide, ferrite oxide, etc.) percolated into the soil from the I/P lagoons. All of these are “pollutants, irritants or contaminants” within the meaning of the policy. Additionally, all costs were incurred pursuant to a “governmental direction . . . that the named insured test for, monitor, clean up, remove, contain, treat, detoxify or neutralize” such pollutants, irritants or contaminants, within the scope of the “pollution exclusion.”
The only materials even arguably outside the clear ambit of the pollution exclusion were the solid wastes (i.e., the wood, bricks, cement, unused ferrite, etc.) which were part of the cleanup. However, to extent these *469 wastes were outside the “pollution exclusion” because they were not contaminants infecting the groundwater they also were not injurious to third party property. Instead, these wastes represented problems limited to the site, to which portion of the cleanup the “owned property” exclusion applies.
B. Principles of Insurance Policy Interpretation
An insurance policy, like all contracts, is to be interpreted to effectuate the mutual intent of the parties.
(AIU Ins. Co.
v.
Superior Court,
supra,
However, the predicate to interpreting ambiguities in favor of coverage is that the policy be
reasonably
susceptible to more than one interpretation. Where a policy clearly excludes coverage, we will not indulge in tortured constructions to divine some theoretical ambiguity in order to find coverage.
(City of Laguna Beach
v.
Mead Reinsurance Corp.
(1990)
The determination of whether a contract is ambiguous is subject to independent review by this court.
(Winet
v.
Price
(1992)
C. The Absolute Pollution Exclusion Unambiguously Excludes Coverage for Costs Associated With Injuries From or Cleanup of the TCE
The language of Aetna’s policy endorsement regarding pollution coverage has been described by some courts as an “absolute” pollution exclusion. (See, e.g.,
Alcolac Inc.
v.
California Union Ins. Co.
(D.Md. 1989)
Titan commendably does not attempt to argue that TCE, a hazardous chemical under federal law (see
Intel Corp.
v.
Hartford Acc. & Indem. Co., supra,
The relevant policy language may be ambiguous on whether solid wastes (the scrap ferrite, brick, rubble, wood debris, etc.) fall within the exclusionary language. The policy defines “pollutants” as “any solid . . . irritant or contaminant, including . . . waste. Waste includes materials to be recycled, reconditioned or reclaimed.” (Italics added.) Titan seizes the highlighted language to argue that debris, although both “solid” and “waste,” is neither an irritant nor a contaminant, and Titan lists cases holding that not all “wastes” necessarily fall within the pollution exclusion. 11 Aetna and amicus curiae argue, on the other hand, that the term “waste” is not limited to *471 “hazardous” waste, but is broadly used. Aetna argues that because the waste removal here was part of a government-compelled cleanup, and the policy excludes any “expense[s] arising out of any governmental direction or request that the named insured . . . clean up, remove, contáin, treat, detoxify or neutralize pollutants,” the waste is within the exclusionary clause.
Here, we may presume Titan to be correct in asserting that the solid waste was not a contaminant nor was it cleaned up to prevent a “threatened discharge, dispersal, release or escape of pollutants.” However, assuming the solid waste did not threaten to contaminate the groundwater or any other third party property, the only property injured by the presence of the waste was the Keasbey site itself. On that assumption, the solid waste comes within the “owned property” exclusion, to which we now turn.
D. The Owned Property Exclusion Precludes Recovery for Costs to Remove Solid Wastes Which Injured Only the Insured’s Property and Not Third Party Property
The solid wastes were situated solely on the Keasbey site. While the presence of solid wastes on the site may have damaged the insured’s property, it appears to have caused no actual injury to third party property. The Aetna policy provided: “This insurance does not apply: . . . (k) to property damage to (1) property owned or occupied or rented to the insured; (2) property used by the insured. . . .” The solid waste removal falls within this exclusion.
Titan seeks to preserve the judgment by arguing that because groundwater represents third party property, the courts have refused to apply the “owned property” exclusion where the groundwater was contaminated. (See
AIU Ins. Co.
v.
Superior Court, supra,
Titan relies on numerous cases as holding that if there is existing contamination, efforts to clean up the site fall outside the owned property exclusion.
*472
These cases are inapposite, because they invariably concluded the “owned property” exclusion did not apply where there was existing contamination damage to third parties
and
the cleanup costs were incurred to ameliorate actual injury
and to prevent the contaminants from continuing to injure or threaten third
parties.
13
Thus in
Intel Corp.
v.
Hartford Acc. & Indem. Co., supra,
The courts of California and New Jersey, as well as their federal counterparts, have excluded from coverage measures taken to prevent future *473 contamination, as distinct from those steps taken to abate continuing harm from extant sources of contamination. In applying those guidelines here, the facts demonstrate the solid waste cleanup is outside the coverage afforded by the Aetna policy. First, as discussed above (see fn. 4, ante), the rubble cleanup was not ordered because it was causing continuing groundwater injury. Instead, the NJDEP simply ordered Titan to sample, properly classify and dispose of solid wastes. Second, to the extent there was evidence the NJDEP had environmental concerns about the solid wastes per se, it was because some of the debris might have been “furnace” brick, which could potentially contain heavy metals such as chromium or cadmium, requiring additional cleanup. If this was the basis for the cleanup, then the “pollution exclusion” was applicable to that part of the cleanup.
Finally, the only evidence of any concern that the rubble might create a “sump effect” on the groundwater table was the admonition that the crushed brick not be disposed of in the deep pit excavations, because “the crushed brick ... is expected to have a much higher permeability than the replaced soils [which] would result in the rapid accumulation of water in a subsurface sink . . . and act as a conduit for any possible future surface spills [to the groundwater table].” This evidence reveals two fatal flaws in Titan’s argument in favor of coverage: (1) It shows the “threat to groundwater” was posed not by the solid wastes per se but by the proposed disposal method for some of those wastes; and (2) it shows the “threat to groundwater” related to “any possible future surface spills”—precisely the type of prophylactic cost uniformly found excluded by the courts.
In short, Titan’s efforts to avoid the exclusions rest on a “Catch-22” argument—that is, the solid wastes were not contaminants (thus avoiding the pollution exclusion), but were remediated because of their contamination of third party property (thus avoiding the owned property exclusion). Titan cannot have it both ways. There is no coverage for the solid waste disposal.
E. The Personal Injury Endorsement Does Not Negate the Policy Exclusion for Property Damage Caused by Pollution
Titan also seeks refuge in the “personal injury” coverage, which covers injuries arising out of, among other things, the “wrongful entry or eviction or other invasion of the right of private occupancy.” The trial court held, in a footnote to its primary opinion, that “the expenses constitute sums which Titan is obligated to pay because of ‘personal injury,’ and fall within that coverage as well since they were incurred because of a wrongful entry or eviction or invasion of the right of private occupancy.”
The trial court’s approach violates basic principles of contract interpretation. We interpret contracts (including insurance policies) as a whole,
*474
with each clause lending meaning to the others.
(Producers Dairy Delivery Co.
v.
Sentry Ins. Co., supra,
We interpret the coverage afforded by the personal injury portion of the policy as being limited to damages
other
than the injury to realty which an occupier of land may suffer when his quiet enjoyment of occupancy is disturbed. (Accord,
Nichols
v.
Great American Ins. Companies
(1985)
Courts in other jurisdictions have also interpreted this clause to limit its coverage to injuries personal to the occupant, as distinct from the damage to the realty. (See, e.g.,
Leek
v.
Reliance Ins. Co.
(Fla.Dist.Ct.App. 1986)
Other courts have similarly refused to find coverage for pollution damage to property under the rubric of an “other invasion” clause of a personal injury endorsement because such approach would render the pollution exclusion meaningless. (See
County of Columbia
v.
Continental Ins.
(1993)
We acknowledge that some federal courts have construed the “personal injury” clause to cover pollution damage. In
Titan Holdings Syndicate, Inc.
v.
City of Keene, N.H.
(1st Cir. 1990)
Titan also relies on
Pipefitters Welfare Educ. Fund
v.
Westchester Fire, supra,
More importantly, to the extent the holding in
Pipefitters
was intended to declare that
any
injury to property is
also
an “other invasion” of a right of
*476
occupancy, we disagree. We must examine the language in context to determine whether an insured would have an objectively reasonable expectation of coverage.
(Bank of the West
v.
Superior Court
(1992)
Disposition
The judgment is reversed. The trial court is directed to enter judgment in favor of Aetna in accordance with the views expressed in this opinion. Titan shall bear costs on appeal.
Notes
The primary contaminants in the waste sludge flowing into the lagoons were fine grain oxides of metal (i.e., ferrite, zinc oxide and ferrite oxide), which metals contaminated the water percolating into the soil.
Among the areas of contamination identified in this initial 1985 report were the I/P lagoons; the I/P lagoon “overflow area” (an area which contained the same contaminants as the lagoon due to occasional overflow from the lagoons); underground oil storage tanks, which had leaked and contaminated the adjacent soil; an above-ground fuel oil transfer line, which had leaked and caused extensive contamination of the ground along the fuel line; and an area near the “dump” where superficial soil stains suggested that storage drums had leaked.
TCE is the shorthand reference for trichloroethylene, classified as a “hazardous substance” under federal law. (See
Intel Corp.
v.
Hartford Acc. & Indem. Co.
(9th Cir. 1991)
The trial court found the reason the NJDEP ordered removal of the solid wastes was to prevent them from creating a “sump” effect, which could have facilitated subsequent *464 migration of contaminants into the groundwater. We have searched in vain for any evidence to support this conclusion. Although the June 1986 NJDEP report identified solid wastes for cleanup, it did not indicate any concern the solid wastes posed a threat of creating a “sump.” Instead, it merely stated the waste must be sampled for purposes of classification and removed, and further stated that some of the brick might be “furnace” brick with heavy metal contaminants which would require sampling and special handling.
The only reference in that report to a “sump” problem was the NJDEP admonition that some of the waste brick could be crushed and used for backfill in shallow trenches (subject to sampling for heavy metal pollutants), cautioning, however, that it would be inappropriate to use the crushed brick to fill the pits created by the fuel tank excavation because of the concern the pit might act as a sink hole and be a “conduit for any possible future surface spills.”
The parties did stipulate that any solid wastes disposed of “on site” were required to be ground up in order to make them compatible with the existing soil, preventing a sump effect. This is not, however, the equivalent of stipulating that the reason the solid wastes were ordered removed was because their mere presence at the site created a sump effect.
On appeal, amicus curiae Insurance Environmental Litigation Association (hereafter am-icus curiae) argues the cleanup costs did not constitute property damage, and hence the trial
*466
court erred in applying
AIU
because under
AIU
the only covered costs are those incurred to comply with cleanups under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 (42 U.S.C. § 9601 et seq.) (CERCLA) “and similar statutes.”
(AIU Ins. Co.
v.
Superior Court, supra,
The court also found the NJDEP had required the removal of solid wastes to eliminate the sump effect in the groundwater table in order to prevent future contamination of the groundwater. The court apparently misconstrued the stipulated facts, and we can find no evidence to support this conclusion. (See fn. 4, ante.)
The error regarding “waiver of non-asserted defenses” is also moot because even if the-“known loss” and “manifestation” issues were waived as to the problems known to Titan prior to 1986, these same problems would appear to fall under the policy exclusion which Aetna did assert—the pollution exclusion. There is little doubt that cleanup of the I/P lagoons, the fuel oil tank and transfer lines, and the soil around the drum storage area was undertaken to remove “contaminants” threatening the groundwater, within the scope of the pollution exclusion. Thus, even had Aetna waived the “known loss” and “manifestation” issúes, it would still prevail under the pollution exclusion.
While some federal courts have held the “expected or intended” clause precludes coverage where a business regularly disposed of chemicals that it knew
or should have known
involved a probability of contamination (see, e.g.,
American States Ins. Co.
v.
Maryland Cas. Co.
(E.D.Mich. 1984)
The California cases cited by Titan are inapposite. In
Pepper Industries, Inc.
v.
Home Ins. Co.
(1977)
The fuel oil and I/P lagoon problems would also appear to be clearly within the pollution exclusion.
’Titan cites an impressive list of cases which have rejected a mechanistic approach to whether a given substance is or is not an “irritant,” “contaminant” or “pollutant” under the exclusionary clause. (See, e.g.,
Westchester Fire Ins.
v.
City of Pittsburg, Kan.
(D.Kan. 1991)
The trial court’s findings are in accord. The court found that “the cleanup activity . . . was undertaken in order to remedy existing groundwater . . . pollution, as well as contamination of adjacent properties, and to prevent further contamination of these areas. The TCE *472 spill, the I/P lagoon area, the drum storage area, the underground storage tanks and adjacent soil and the soil contaminated by the fuel oil transfer line were all remediated to remove sources of existing and/or potential contamination of groundwater. The NJDEP also required that any solid waste disposed of at the site be ground up to be compatible with the soil, so that it would not cause a sump effect in the groundwater table. The NJDEP was also concerned that the nonpollutants at the site would form a conduit for contamination at the site, leading to further contamination of groundwater. The fact that no actual treatment of the groundwater itself was required is irrelevant, since the evidence clearly shows that contamination did exist, and that the cleanup was motivated by the NJDEP’s desire to prevent further contamination.” (Italics added.) As the highlighted language shows, the trial court found the cleanup of the pollutants was done to remediate existing and potential future contamination. The NJDEP’s requirement of trash cleanup is irrelevant to the pollution issue.
Titan cites what it characterizes as “an unbroken line of authority” holding that the existence of groundwater contamination renders the “owned property” exclusion inapplicable. (See, e.g.,
Gloucester TP.
v.
Maryland Cas. Co.
(D.N.J. 1987)
Ejusdem generis instructs that where general words follow a specific enumeration, the general words should not be construed in their broadest sense but should read as applying to the same general class of things as the specifically enumerated things. (Black’s Law Dict. (4th ed. 1968) p. 608, col. 1.)
The distinction is significant because the
Pipefitters
court expressly did not reach the issue of whether the insurer would be required to
indemnify
the insured, since it recognized
*476
that such question depended on “. . . the type of relief, if any, ultimately obtained in Arst’s suit.”
