New York City pursued claims against Exxon Mobil arising from alleged MTBE contamination in City-owned groundwater wells in Queens. The dispute proceeded within the coordinated In re MTBE Products Liability Litigation in the Southern District of New York, and a jury found Exxon liable before the court entered judgment in the City’s favor for $104.69 million. On appeal, the U.S. Court of Appeals for the Second Circuit affirmed the judgment, addressing core issues that included whether the City’s tort-based claims were barred by federal preemption and whether the trial record and legal standards supported the liability and damages findings.
After the affirmance, Exxon sought Supreme Court review, and certiorari was denied, leaving the judgment in place and closing merits review. Post-judgment motion practice followed in the district court, including Exxon’s request for a court-supervised trust to control how the judgment funds would be used, which the City opposed as inconsistent with the judgment structure. The record consistently frames the case around MTBE in drinking-water supply wells and related remedial response costs tied to environmental contamination of groundwater used for public water supply.
On October 31, 2003, New York City sued Exxon and other petroleum companies, alleging injuries to its water supply from gasoline containing MTBE. The case proceeded within the In re MTBE Products Liability Litigation in the Southern District of New York. The litigation later moved toward trial against Exxon on the City’s claims tied to MTBE impacts on City-owned groundwater wells.
On March 9, 2007, New York City filed its Fourth Amended Complaint in the coordinated MTBE litigation. The pleading set out the City’s claims against Exxon and other petroleum companies relating to alleged MTBE contamination affecting the City’s groundwater well system. As later summarized by the Second Circuit, the complaint sought recovery of costs and damages the City had incurred, was incurring, and expected to incur for investigating, detecting, monitoring, preventing, abating, containing, removing, and remediating alleged MTBE impacts on the City’s groundwater supply wells.
On August 3, 2009, the City began a jury trial against Exxon over past and projected MTBE contamination at the Station Six wells in Queens. A major part of the City’s case came from hydrogeologist David Terry, who used groundwater modeling to project whether MTBE would reach the Station Six capture zone, at what levels it could appear in the combined outflow, and how long contamination might persist. Exxon responded with Thomas Maguire, who challenged Terry’s methods and reliability.
The City also presented expert testimony on why MTBE in a backup drinking-water source would still require a response. Kathleen Burns and Kenneth Rudo addressed toxicological concerns, while Harry Lawless testified about MTBE’s taste-and-odor detectability in drinking water. Exxon countered with Dr. Sandra Mohr, who disputed the City’s stronger carcinogenicity and mutagenicity claims.
For damages, the City called groundwater treatment expert Marnie Bell, who testified about the cost of treating MTBE at Station Six. Her testimony addressed treatment design below the applicable MCL, New York State’s lowest-practical-level requirement for organic contaminants, and cost projections for options including granular activated carbon and air stripping.
On October 19, 2009, the jury found Exxon liable on the City’s claims of public nuisance, negligence, trespass, and product liability for failure to warn. The jury did not find Exxon liable on the private nuisance claim or on the design defect theory. The verdict came after the jury had heard competing testimony on future contaminant levels at Station Six, the public-water implications of MTBE taste and odor, and the parties’ conflicting positions on the significance of MTBE’s toxicological profile.
On April 5, 2010, the district court issued a substantive post-trial opinion in the MTBE MDL addressing issues arising from the City’s trial against Exxon. The opinion helped shape the case’s post-verdict posture in a dispute that had already been driven by technical testimony on contaminant migration, projected well impacts, and the reasonableness of response measures tied to a public water supply.
After the jury’s findings, the court entered an amended judgment reflecting the damages award and the jury’s allocation of fault. The judgment followed a trial record that included detailed modeling evidence about expected MTBE levels at Station Six, as well as testimony intended to explain why projected contamination at those wells mattered from both a water-quality and public-acceptability standpoint.
On July 26, 2013, the Second Circuit affirmed the district court’s $104.69 million judgment in favor of the New York City entities. The court upheld the liability and damages rulings after reviewing the trial record, including the parties’ competing expert evidence on projected MTBE impacts, treatment costs, toxicology, and taste-and-odor issues. The court also rejected Exxon’s impossibility-preemption argument. In that analysis, it cited testimony from Exxon expert O’Brien, who acknowledged that ethanol supply could expand with demand and that ethanol could be transported by train, truck, or barge. That testimony weakened Exxon’s claim that MTBE was the only feasible oxygenate under federal fuel requirements.
On April 21, 2014, the Supreme Court denied Exxon’s petition for certiorari. That denial left the Second Circuit’s affirmance undisturbed and made the judgment final for purposes of further district court proceedings. By that point, the case record had already been shaped by a substantial evidentiary battle over how MTBE would behave in groundwater, how it could affect the future usability of the Station Six wells, and why the City claimed treatment-based response costs were justified.
After the Supreme Court denied certiorari, Exxon filed a motion on May 16, 2014 seeking a court-supervised trust to control how the judgment funds would be used. The City opposed the request, and the district court denied the motion on July 30, 2014. The ruling left the judgment in place without imposing the trust structure Exxon sought.

Hydrogeologist Expert Witness (Plaintiff)
David Terry is described as the City’s principal Phase II witness and a hydrogeologist. He testified about groundwater models he created to estimate future MTBE levels at the Station Six wells, including how groundwater flow and contaminant movement were modeled. His opinions were used to support the City’s projections about when and at what levels MTBE would appear in the combined outflow.
Groundwater Treatment and Damages Cost Expert Witness (Plaintiff)
Marnie Bell is identified as a groundwater treatment expert called by the City to quantify damages tied to treating MTBE at Station Six. She testified about standard engineering practice for designing treatment below an MCL and about New York State requirements discussed in her testimony for designing treatment systems for organic contamination to remove contaminants to the lowest practical level. She also provided cost estimates for treatment technologies discussed in the record, including granular activated carbon and air stripping, and explained key assumptions used in her projections.
Toxicology Expert Witness (Plaintiff and Defense)
Plaintiff: Rudo and Kathleen Burns are identified in the record as witnesses who testified about the toxicological characteristics of MTBE. Their testimony included opinions describing MTBE as mutagenic and addressing potential carcinogenic risks, which the City relied on to support its position that treatment of contaminated groundwater wells would be reasonable. Exxon disputed aspects of this toxicology evidence through its own expert testimony presented during the trial.
Defense: Dr. Sandra Mohr is identified as a witness presented by Exxon who disputed the City’s toxicology testimony. The record describes her testimony as stating that neither the EPA nor the National Toxicology Program had classified MTBE as a human carcinogen and that, in her view, MTBE was not carcinogenic in humans. Her testimony also addressed the strength of evidence for mutagenicity as described in the record.
Taste-and-Odor Expert Witness (Plaintiff)
Harry Lawless is identified as a professor in Cornell University’s food science department who testified about the taste and odor characteristics of MTBE. He discussed scientific literature on the portion of the population sensitive to MTBE taste and smell at various concentration levels and offered opinions about detectability thresholds. This evidence was tied to water acceptability and consumer response issues discussed in the record.
Groundwater Modeling Critique Expert Witness (Defense)
Thomas Maguire is identified as an expert presented by Exxon who criticized Terry’s groundwater models. The record describes him as concluding that the models were fatally flawed and that the methods used were scientifically invalid. This testimony was aimed at challenging the reliability of the City’s projections used in the case.
Fuel Oxygenate Logistics Expert Witness (Defense)
O’Brien is identified as Exxon’s expert in the preemption-related record addressing ethanol as an alternative oxygenate. The record describes his testimony as conceding that ethanol supply could adjust to meet increased demand and that ethanol could be transported by trains, trucks, or barges, including references to how producers shipped ethanol at the time. This testimony is discussed in the court’s analysis of whether Exxon had shown impossibility preemption.
Environmental Expert Witness
An environmental expert witness is often engaged to connect groundwater contamination facts to response planning and to explain how treatment design choices align with stated water-quality goals and constraints. In MTBE cases, that can include evaluating remedy feasibility, anticipated duration of treatment needs, and how response measures are framed within the record of contamination at public supply wells.
Frame preemption as a record-based feasibility fight, not an abstract theory.
A central defense effort argued that federal law displaced state-law claims, including an impossibility theory tied to oxygenate requirements. The appellate outcome turned in meaningful part on whether the defense could show that compliance with both regimes truly could not occur under the factual record presented. Attorneys should treat preemption as an evidence-driven issue and build the proof early, especially where fuel formulation decisions and alternatives are in dispute.
Treat groundwater modeling as a merits-and-damages battleground requiring disciplined foundations.
Future contamination projections were built on groundwater modeling, and the defense attacked those models as unreliable and methodologically unsound. When models drive the remedy narrative, counsel should expect foundational challenges, rebuttal testimony, and close scrutiny of assumptions and inputs. Clear documentation of methods and a defensible bridge from data to projections can be outcome-determinative in environmental groundwater disputes.
Connect damages to specific treatment objectives and operational decisions for public supply wells.
The damages presentation centered on treatment to meet defined targets for drinking-water use and on cost estimates tied to treatment technologies and design assumptions. The record shows the court evaluating whether the proposed approach and costs fit the case posture and the claimed need to treat contaminated wells. Lawyers should align damages evidence to concrete response decisions and avoid leaving cost models untethered to the claimed remediation pathway.
Use toxicology and sensory evidence carefully to support reasonableness of response actions.
The case included testimony addressing toxicological risk concepts and testimony about taste-and-odor detectability, both used to explain why MTBE in water supply wells mattered to the City’s response position. The defense contested aspects of these topics, making the scientific framing part of the contested trial terrain rather than background context. In environmental contamination cases, attorneys should tie health and acceptability evidence to the precise legal elements at issue, rather than relying on broad assertions.
Anticipate post-judgment fights over remedies administration after merits review ends.
After the judgment was affirmed on appeal and further review was denied, the dispute continued into post-judgment motion practice over how judgment funds would be controlled or administered. That phase shows that “final resolution” may still involve litigation over implementation mechanics even when liability and damages are fixed. Counsel should plan for enforcement and administration strategy as part of the case plan, particularly where large remediation-related sums and long-term response work are involved.
The New York City MTBE litigation against Exxon concluded with a final judgment for the City that was affirmed on appeal, leaving the damages award in place and closing merits review after further review was denied. The case moved from liability findings to detailed disputes over future conditions at City-owned wells and the cost and design assumptions tied to treating MTBE for public water supply use. It also continued into post-judgment motion practice, showing that even after appellate finality, parties may still litigate how a judgment should be administered.
For attorneys, the record shows how an environmental contamination dispute over MTBE in groundwater can turn on careful proof about drinking-water wells, projected contaminant levels, and the technical basis for treatment planning and cost estimates. The case also reflects the role of testimony on toxicity and taste-and-odor considerations in explaining why response actions were pursued for a public water system. Taken together, the litigation offers a fact-driven example of how courts assess contested evidence in groundwater contamination claims and how final judgments can lead to additional proceedings over implementation details.
What was New York City v. Exxon Mobil about in the MTBE groundwater litigation?
The case focused on New York City’s claims that gasoline containing MTBE contaminated City-owned groundwater wells in Queens. The City sought damages tied to responding to MTBE in its public water supply wellfield, including treatment-related costs. The dispute proceeded within the In re MTBE Products Liability Litigation in the Southern District of New York.
What was the outcome of the New York City MTBE case against Exxon?
A jury found Exxon liable on several claims, and the district court entered judgment for the City in the amount of $104.69 million. The Second Circuit affirmed that judgment on July 26, 2013. The Supreme Court denied further review on April 21, 2014, leaving the judgment in place.
Which legal claims succeeded and which claims did not?
The jury found Exxon liable for public nuisance, negligence, trespass, and product liability failure to warn. The jury did not find Exxon liable on the City’s private nuisance claim or on the product liability design defect claim. Those findings framed the final judgment that was later affirmed on appeal.
Did federal preemption defeat New York City’s claims against Exxon?
Exxon argued that federal law preempted the City’s state-law claims, including an impossibility theory tied to oxygenate requirements. The Second Circuit rejected the preemption arguments and affirmed the judgment. The appellate ruling kept the City’s tort-based claims and damages award intact.
What did the courts focus on when evaluating damages and response costs?
The damages dispute centered on projected MTBE impacts on the Station Six wells and the cost and design assumptions for treating MTBE in public water supply operations. The record addressed treatment targets tied to drinking-water standards and how treatment would be designed and paid for over time. These points were central to the court’s treatment of remediation-related damages tied to groundwater wells.
Hydrogeologist Expert Witness (Plaintiff)
