Court:
West Morgan-East Lawrence Water and Sewer Authority and affected customers sued 3M, Dyneon, and Daikin in federal court in Alabama, alleging that PFAS chemicals released from the defendants’ Decatur operations entered the Tennessee River and reached the Authority’s drinking-water intake downstream. The pleadings described contamination involving PFOA, PFOS, and related compounds, and alleged resulting damage to the Authority, residential water users, and property interests served by the Authority and connected utilities. The case developed through multiple pleadings, motions to dismiss, settlement proceedings, and an appeal. In an earlier phase, the Eleventh Circuit vacated approval of a partial class settlement with Daikin, finding problems with class representation and the release of absent class members’ individualized monetary claims. The litigation then continued with revised representation, later settlements, and additional court rulings that narrowed certain claimed remedies.
The later record shows a combination of procedural rulings and settlement-based resolution. In 2020, the district court ruled that Alabama law did not allow recovery for diagnostic-testing costs without a present physical injury and dismissed the trespass count as pleaded, while the broader contamination dispute continued. Subsequent settlement filings stated that prior relief obtained in the case had been used to install a granular activated carbon filtration system and later a reverse osmosis system for the Authority’s water supply, while a proposed $12 million class settlement addressed specified customer claims and preserved certain manifest-injury and biosolids-related property claims. In that sense, the dispute falls naturally within environmental engineering because the source materials center on industrial wastewater discharges, impaired surface water, treatment-system limits, and later filtration upgrades designed to reduce PFAS in distributed drinking water.
West Morgan-East Lawrence Water and Sewer Authority and representative plaintiffs opened the case by suing 3M, Dyneon, and Daikin in federal court in Alabama. The complaint alleged that PFAS discharges from Decatur operations entered the Tennessee River, reached the Authority’s intake about thirteen miles downstream, and could not be removed by the treatment processes then in use at the Robert M. Hames Water Treatment Plant. From the outset, the dispute turned on water-treatment limits, upstream industrial discharge pathways, and contamination of a public drinking-water source.
The district court granted in part and denied in part the defendants’ motions to dismiss, trimming portions of the pleadings while allowing the central contamination dispute to continue. The litigation therefore moved forward on the core allegations involving PFAS discharges, downstream drinking-water impacts, and treatment-related limitations.
Later filings state that a granular activated carbon system became effective on this date and began removing longer-chain PFAS such as PFOA and PFOS before water was distributed to customers. That treatment step matters to the case narrative because it marked the first major relief tied to the litigation and provided concrete environmental engineering context about filtration upgrades rather than only damages claims. The same filings also note that shorter-chain PFAS were not always completely removed by the GAC system.
Plaintiffs sought approval of a pro tanto settlement with Daikin. According to later settlement papers, Daikin agreed to fund installation of the GAC system and to pay $450,000 in monetary compensation to proposed class members. This moved the case from pleading-stage conflict into an early settlement phase tied both to customer compensation and to treatment-system improvements.
After preliminary approval and a fairness hearing, the district court granted final approval of the Daikin settlement. The settlement gave the case an early partial resolution and tied financial relief to the water authority’s response to PFAS in distributed water. At that point, the legal posture appeared to favor a class-based resolution for at least part of the dispute.
The Eleventh Circuit changed the course of the case by vacating class certification, reversing approval of the settlement, and remanding for further proceedings. The court concluded that counsel faced a conflict between the Water Authority and the class and that the settlement improperly released absent class members’ individualized monetary claims without the protections required for that kind of class treatment. That ruling reopened the case and forced a restructuring of representation and settlement strategy.
Later filings state that new counsel appeared for the individual plaintiffs on July 17, 2018 in response to the issues identified by the Eleventh Circuit. On the same date, WMEL also filed a joint motion to dismiss its claims against Daikin after reaching its own agreement. This was a turning point because the case began separating the Authority’s path from the class plaintiffs’ path.
The district court granted the motion dismissing WMEL’s claims against Daikin. By this stage, the Authority had resolved its own claims against one defendant, while the broader litigation continued on behalf of the individual and proposed class plaintiffs. The case was no longer moving as a single block of claims with identical settlement interests.
WMEL later filed a joint stipulation dismissing its claims against 3M and Dyneon, and the court dismissed those claims. The settlement papers state that WMEL’s claims against all defendants had been settled and dismissed by that point. The remaining case then centered on the individual and class plaintiffs’ claims rather than the Authority’s direct claims.
The district court granted 3M and Dyneon’s motion to dismiss the plaintiffs’ attempts to recover diagnostic-testing costs and dismissed the repleaded trespass claim. The court held that Alabama law does not allow recovery for diagnostic-testing costs without a present physical injury and found that the trespass theory still failed to allege the required substantial damage to the property itself. That ruling narrowed the available remedies and claims, pushing the case further toward negotiated resolution.
The 2021 settlement memorandum states that WMEL’s reverse osmosis system came online in May 2021. The filing describes it as an improvement over the GAC system, notes testing against 29 PFAS compounds, and presents it as long-term treatment relief expected to continue for decades. In practical terms, the record moves from allegations about contamination and treatment limits to a cleaner-water remedy built around advanced filtration.
Class representatives moved for final approval of a settlement class and a proposed $12 million class settlement. The settlement papers describe compensation for ratepayers, household members, and household owners for PFAS-contaminated potable water distributed during the defined class period, while preserving manifest bodily injury claims and certain biosolids-related property claims. This filing placed the remaining customer claims in the final approval stage after earlier settlements had already resolved WMEL’s direct claims against the defendants.
The settlement website identified March 15, 2022 as the fairness-hearing date, and later 3M disclosures state that the court issued a final order approving the class settlement and dismissing the action in March 2022. CourtListener also lists the case as terminated on March 15, 2022. Based on that sequence, the federal action can be described as reaching final resolution in March 2022 through settlement approval and termination of the case.

An environmental engineering expert is often engaged in drinking-water contamination cases involving treatment-system limits and long-term corrective measures. In a case like this, that expert would commonly assess how PFAS moved from industrial discharge points into a public water source, whether existing treatment processes could remove the contaminants, and how later system upgrades addressed those limits. That role fits the record because the case materials repeatedly address PFAS in distributed water, followed by granular activated carbon and reverse osmosis upgrades.
A water treatment expert is often engaged when a case turns on filtration performance, system design, and whether a utility’s process could reduce contaminants to acceptable levels. In similar disputes, this expert commonly reviews plant operations, treatment capacity, contaminant-removal performance, and the effect of replacement technologies such as granular activated carbon or reverse osmosis. That type is relevant here because the record discusses treatment limits at the water plant and later filtration improvements.
A hydrogeology or soil and water contamination expert is often engaged to evaluate contaminant pathways through groundwater, surface water, tributaries, and downstream intake locations. In this kind of matter, that expert would commonly analyze how chemicals released from manufacturing or disposal operations reached the river, moved through the watershed, and entered the public supply. That type fits this case because the pleadings and later filings describe PFAS discharges into Bakers Creek, the Tennessee River, and the Authority’s downstream intake.
An environmental toxicology expert is often engaged when the dispute involves the health significance of chemical exposure and the persistence of contaminants in the body or environment. In similar litigation, this expert commonly addresses dose, exposure pathways, persistence, bioaccumulation, and the meaning of reported contaminant levels. That role is a natural fit here because the record discusses alleged health risks associated with PFOA and PFOS exposure and refers to elevated serum findings among some water users.
This litigation shows the value of tying industrial discharge allegations to a clear downstream pathway into a public drinking-water intake. Attorneys strengthened the factual record by connecting facility releases, river transport, treatment limits, and distributed household water. In environmental engineering terms, the dispute turned on source-to-intake movement, treatment performance, and the practical limits of existing filtration systems.
One of the most important lessons from this case is that a water authority’s goals may differ from the goals of individual customers, even when both arise from the same contamination event. Relief tied to infrastructure funding, account credits, and classwide releases can affect those groups in different ways. When settlement terms divide along those lines, attorneys should evaluate representation structure early and carefully.
The record shows that filtration upgrades became a central part of the case’s development, first through granular activated carbon and later through reverse osmosis. That matters strategically because system design, contaminant removal limits, and long-term treatment needs can frame both the harm and the remedy. In a PFAS case, environmental engineering evidence can therefore support not only causation themes but also the practical value of negotiated relief.
The district court’s rulings show the importance of matching claimed damages to what the governing law clearly permits. Claims tied to future diagnostic testing faced a legal barrier where the court found no recovery without a present physical injury, and the trespass theory was also narrowed. Attorneys handling contamination cases should test each remedy theory against state-specific tort standards before making it a major part of the case.
The settlement papers in this matter took a careful approach by addressing certain water-related claims while preserving manifest bodily injury claims and certain biosolids-related property claims. That kind of drafting matters because contamination cases often involve both immediate water-use concerns and later-developing injury issues. A well-structured settlement can move the case toward resolution while reducing the risk that overbroad releases will trigger later objections or appellate problems.
The West Morgan PFAS litigation ended as an Alabama drinking-water case involving industrial discharges, class-action procedure, settlement review, and water-treatment relief. The record shows a dispute that moved from contamination allegations and contested pleadings to filtration-system upgrades, separate settlements for the water authority, a later class settlement process, and final termination of the federal action. More broadly, the case shows why environmental engineering issues can become central in water-contamination litigation, especially where the facts turn on discharge pathways, treatment-system limits, granular activated carbon, reverse osmosis, and the practical challenge of reducing PFAS in a public drinking-water supply.
What was the West Morgan v. 3M case about?
The case concerned allegations that PFAS chemicals released from industrial operations in Decatur, Alabama entered the Tennessee River and affected the drinking-water supply used by West Morgan-East Lawrence Water and Sewer Authority and connected utilities. The litigation involved claims by the Authority and by customers who said they received contaminated water.
Who were the defendants in the West Morgan PFAS lawsuit?
The defendants were 3M Company, Dyneon, L.L.C., and Daikin America, Inc. The case record tied the dispute to PFAS discharges or related wastewater pathways associated with their Decatur-area operations.
Why was PFAS removal such a central issue in the case?
The case turned on whether PFAS released upstream could remain in the river, reach WMEL’s intake, and pass through the Authority’s existing treatment process into distributed drinking water. That issue mattered because the record tied the dispute not only to alleged contamination, but also to the limits of the treatment system then in use. It also explains why later filtration upgrades became part of the case’s relief and broader environmental engineering context.
What treatment changes were connected to the case?
The record states that relief obtained in the litigation was used first for a granular activated carbon system and later for a reverse osmosis system at WMEL. Those treatment measures matter because they relate directly to environmental engineering issues such as contaminant removal, plant design, and PFAS reduction in distributed drinking water.
Did the court approve every type of damage claim asserted by the plaintiffs?
No. In a 2020 ruling, the district court rejected claims for diagnostic-testing costs without a present physical injury and dismissed the trespass claim as pleaded. That ruling narrowed the case even while the broader contamination dispute continued.
