UNITED STATES DISTRICT COURT FOR THE NORTHERN DISTRICT OF ILLINOIS EASTERN DIVISION

ROZITA ARNOLD, et al.,

Plaintiffs, No. 25 CV 2522 v. Judge Georgia N. Alexakis AQUA ILLINOIS, INC.,

Defendant.

MEMORANDUM OPINION AND ORDER

Rozita Arnold and numerous other residents of the Village of University Park, Illinois (“plaintiffs”) are suing Aqua Illinois, Inc., the operator of University Park’s public water system, to recoup costs they incurred in response to the alleged detection of lead in some University Park homes’ tap water. They bring claims under the Comprehensive Environmental Response, Compensation, and Liability Act of 1980, 42 U.S.C. § 9601 et seq., as well as several state-law claims. Aqua now moves to dismiss their complaint for failure to state a claim upon which relief can be granted under Rule 12(b)(6) of the Federal Rules of Civil Procedure. For the following reasons, the motion to dismiss is granted. I. Legal Standard A complaint must contain “a short and plain statement showing that the [plaintiff] is entitled to relief.” Fed. R. Civ. P. 8(a)(2). A motion to dismiss under Rule 12(b)(6) challenges the sufficiency of the complaint, not its merits. See Fed. R. Civ. P. 12(b)(6); Gibson v. City of Chicago, 910 F.2d 1510, 1520 (7th Cir. 1990). To survive a Rule 12(b)(6) motion, the complaint need only “state a claim to relief that is plausible on its face.” Ashcroft v. Iqbal, 556 U.S. 662, 678 (2009) (citing Bell Atl. Corp. v. Twombly, 550 U.S. 544, 570 (2007)). A claim is plausible “when the plaintiff pleads factual content that allows the court to draw the reasonable inference that the

defendant is liable for the misconduct alleged.” Id. (citing Twombly, 550 U.S. at 556). At this stage, the Court assumes that the facts alleged in the complaint are true and draws all reasonable inferences from those facts in the plaintiffs’ favor. See Tobey v. Chibucos, 890 F.3d 634, 645 (7th Cir. 2018). But the factual allegations “must be enough to raise a right to relief above the speculative level.” Twombly, 550 U.S. at 555. Alleged facts that are “‘merely consistent with’ a defendant’s liability” fall short of the plausibility standard. Iqbal, 556 U.S. at 678 (quoting Twombly, 550 U.S. at

557). Further, “[a] pleading that offers ‘labels and conclusions’ or ‘a formulaic recitation of the elements of a cause of action will not do.’” Id. (quoting Twombly, 550 U.S. at 555). Similarly, a complaint that “tenders ‘naked assertion[s]’ devoid of ‘further factual enhancement’” will not survive a motion to dismiss. Id. II. Allegations Plaintiffs are current and former residents of the Village of University Park,

Illinois. [1] ¶ 3. They allege that Aqua, which owns and operates University Park’s Public Water System, id. ¶ 170, began adding a chemical called SeaQuest to University Park wells, id. ¶ 14, to control the buildup of calcium carbonate inside pipes throughout University Park, id. ¶ 16. When Aqua began sourcing its water from the Kankakee River, it continued its use of SeaQuest. Id. ¶ 17. About eight months after Aqua began using Kankakee River water, residential tap water testing revealed elevated lead levels in the tap water of some University Park homes. Id. ¶¶ 44–45. Additional testing about nine months later revealed

elevated lead levels in more than 10% of tap-water samples. Id. ¶ 60. Aqua soon issued a Do Not Consume notice to the whole University Park service area, which comprised 2,124 unique premises. Id. ¶ 61. Aqua did not know what was causing the elevated lead levels, id. ¶ 62, but it stopped adding SeaQuest to the water system one day after it issued the Do Not Consume notice, id. ¶ 67. Aqua eventually determined that SeaQuest was likely causing the elevated lead levels. Id. ¶ 72. Kankakee River water is softer than the well water that Aqua

previously used, so when Aqua began using Kankakee River water, it no longer needed to add SeaQuest to control mineral buildup. Id. ¶¶ 28, 30. The unnecessary SeaQuest instead had a negative effect, eroding the protective calcium carbonate coating inside the pipes of University Park homes. Id. ¶ 72. Without the protective coating, lead in the homes’ interior plumbing was exposed and leached into the homes’ tap water. Id. ¶ 73.

Six weeks after the issuing the Do Not Consume notice, Aqua lifted the notice and replaced it with a Lead Advisory Area, id. ¶ 79, which was an area comprising 1,634 premises that were suspected to have lead issues, id. ¶¶ 80, 82. Of those premises, 183 were homes constructed after 1990. Id. ¶ 83. From the Lead Advisory Area’s implementation date in July 2019 through April 28, 2023—approximately four years—811 residential tap-water samples tested positive for elevated lead levels. Id. ¶ 88. Some of those samples were from homes constructed after 1990. Id. ¶ 94. Plaintiffs incurred several costs in responding to the release or threatened

release of lead into their tap water, including the cost of bottled water, water filters, medical testing, and water quality testing. Id. ¶ 200. They seek to recoup those costs from Aqua under section 107 of CERCLA, 42 U.S.C. § 9607(a)(4)(B), id. ¶ 201, in addition to bringing multiple state-law claims. III. Analysis A. CERCLA Claim CERCLA has a twofold purpose: “to ‘promote the timely cleanup of hazardous waste sites and to ensure that the costs of such cleanup efforts were borne by those

responsible for the contamination.’” Von Duprin LLC v. Major Holdings, LLC, 12 F.4th 751, 758 (7th Cir. 2021) (quoting Burlington N. & Santa Fe Ry. Co. v. United States, 556 U.S. 599, 602 (2009)). Section 107 of CERCLA provides that “the owner and operator of a … facility … from which there is a release, or a threatened release … , of a hazardous substance, shall be liable for … any … necessary costs of response incurred by any … person consistent with the national contingency plan.” 42 U.S.C.

§ 9607(a)(4)(B). It thus allows private parties to recover the cost of “clean[ing] up hazardous materials that [another] party spilled onto its property or that migrated there from adjacent lands.” NutraSweet Co. v. X-L Eng’g Co., 227 F.3d 776, 784 (7th Cir. 2000) (quoting Azko Coatings, Inc. v. Aigner Corp., 30 F.3d 761, 764 (7th Cir. 1994)). To state a claim for cost recovery under section 107(a) of CERCLA, a plaintiff must plausibly allege that (1) the site in question is a “facility”; (2) the defendant is an owner or operator of the facility or another covered person under section 107(a);

(3) there was a “release” (or threatened release) of a “hazardous substance”; and (4) the plaintiff incurred costs in response to the release. See Sycamore Indus. Park. Assocs. v. Ericsson, Inc., 546 F.3d 847, 850 (7th Cir. 2008); Cont’l Paper Grading Co. v. Nat’l R.R. Passenger Corp., No.
