A Complete Guide to Legacy Litigation in Louisiana
What Is Legacy Litigation?
Legacy litigation is a legal process where property owners sue oil and gas companies to recover damages for contaminating their soil or groundwater. These cases often focus on issues like soil contamination, groundwater contamination, and other toxic waste left behind by historic oilfield operations. Under Louisiana law, landowners can seek full remediation to restore their land to its pre-polluted condition.
Through Legacy lawsuits, landowners directly benefit from property cleanup. A successful claim could fund the removal of contaminated soil and polluted water, restore wildlife habitat, and make property safe for farming, hunting, or building.
By extension, communities and the environment also benefit, as Legacy litigation promotes healthier water, cleaner soil, and revitalized wetlands. When companies pay for cleanup, nearby homes and businesses avoid risks from toxic exposure. The result is safer neighborhoods and stronger local economies.
Common Contamination Issues in Legacy Litigation Cases
Historic oil and gas operations often used open pits and unlined waste ponds. Over time, saltwater brine, drilling mud, and chemicals like benzene and arsenic seeped from these sources into soil and water. As decades passed, that contamination left pockets of toxic chemicals on many Louisiana properties.
Soil Contamination
Historic spills of crude oil, diesel, and other substances left behind thick layers of hydrocarbons that soak into the ground. Drilling operations also used oil-based muds and synthetic fluids to cool and lubricate drill bits. When those spent muds were dumped or leaked, they added toxic residues to the soil. Over time, heavy metals such as arsenic, barium, lead, and mercury also built up around open pits and unlined waste ponds.
Groundwater Contamination
Drilling produces a salty wastewater known as “produced water brine.” When operators dumped or leaked this high-salinity fluid, it carried dissolved oil and salts down into underground aquifers. Leaks from pits and pipelines released benzene, toluene, ethylbenzene, and xylene (the BTEX compounds) into groundwater, putting well water at risk. In some older fields, naturally occurring radioactive materials (NORM) got mobilized by drilling and waste disposal practices, adding another layer of health hazard to water supplies.
The Effects of Land & Water Contamination
All of these pollutants have wide-reaching impacts on landowners, wildlife and our communities at large.
Reduced Land Use & Property Value
Land pollution can strip soil of vital nutrients, preventing crops from growing and livestock from grazing safely. As contamination makes land less productive, buyers steer clear of polluted property and its market value drops.
Additional Costs for Landowners
Beyond declining property values, landowners also often face lost income and costly cleanups or repairs when contaminated land becomes largely unusable. Testing and cleanup can cost thousands to millions of dollars, while landowners are forced to halt their typical revenue streams.
Health Concerns for Humans & Wildlife
Pollutants seep into groundwater wells, making the water unsafe for drinking or irrigation. Toxic chemicals in the soil kill insects and plant life and can sicken grazing livestock. Oil and chemical runoff poisons bayous and ponds, devastating fish and other aquatic life. Humans exposed to these contaminants face health risks ranging from skin rashes, headaches, and nausea to long-term dangers like organ damage and cancer.
Broader Community Impacts
Rainfall and flooding can spread pollutants to other areas and infect the habitats of coastal wildlife. As wetlands die off, Louisiana loses its vital buffer against storms and flooding, and the degradation of marshes and rivers drives down tourism and recreation. Drawn-out legal battles and ongoing cleanup efforts place added stress on communities already coping with environmental harm.
What is Remediation?
Remediation is the process of cleaning polluted earth or water, so it’s safe for people, plants, and animals. Some common remediation methods include:
Excavation of polluted soil or water for off-site disposal, replacing with new, clean soil or water.
Adding natural bacteria (bioremediation) or chemicals (oxidants) that break down oil and other toxins on the spot.
Covering the contaminated zone with a clean layer to prevent exposure
In Legacy litigation, a court-approved remediation plan lays out which technique best fits each site’s pollution type and cleanup goal. Once the plan runs, experts monitor soil and water to confirm the pollution is gone or meets the appropriate standards. Thorough remediation not only protects health and the environment but also restores property value for Louisiana landowners.
What Rights Do Landowners Have with Legacy Litigation?
Legacy litigation in Louisiana dates back to 2006 and Act 312, which created a court-supervised process to force oil and gas companies to clean up historic oilfield pollution. Under Act 312, landowners file suit in state court and notify both the Department of Natural Resources and the Attorney General. The courts then work with technical experts from both sides to develop and approve a cleanup plan for the contaminated land. Landowners only need to prove contamination by a “preponderance of evidence,” and they can recover the full cost to restore soil, groundwater, and wetlands.
In the years that followed, Act 312 has helped hundreds of landowners secure cleanup orders and cleanup-cost awards. In this time, some industry groups have critiqued Legacy litigation for so-called “jackpot” verdicts, delayed drilling, and uncertain cleanup standards. In response, the legislature recently passed Act 458 (effective September 1, 2027), making major changes for cases filed after that date:
- Cleanup plans come from the state agency, not the court, and landowners must prove by “clear and convincing” evidence that an alternative plan is better. This is a tougher legal standard for property owners to overcome.
- Regulators may use “risk-based” standards that allow some pollution to remain.
- Non-cleanup damages (like lost use of land) cap at three times the property’s surface value.
- Once a cleanup plan is final, landowners bear any future monitoring and enforcement costs.
- Courts must stay litigation until the agency approves a plan, adding delays.
In short, Act 312 gave courts broad power to order full cleanups under a low proof standard, while Act 458 shifts power and costs to the state agency, raises the proof bar, and limits damages for new cases after September 2027. Landowners who want the stronger rights under Act 312 must file their claims before that deadline.
Understanding Damages in a Legacy Litigation Case
In a Louisiana Legacy litigation case, landowners can seek compensation for several distinct categories of harm caused by historic oilfield contamination. Together, these damage awards are designed to make landowners feel whole and hold polluters accountable.
Remediation & Cleanup Costs
Legacy litigation primarily seeks coverage of the full cost to remove or treat contaminated soil and groundwater. Additional expenses for expert studies, environmental assessments, and monitoring may also be included.
Monitoring & Enforcement Expenses
After the initial cleanup plan is complete, landowners may also seek monetary assistance for ongoing costs to test soil, groundwater, or surface water and respond to additional regulatory changes.
Reduced Property Value
Landowners also often seek the difference between the fair market value of the land before contamination and its value afterwards.
Attorney’s Fees & Litigation Costs
Under the current law (Act 312), prevailing landowners can recover reasonable attorney fees and expert-witness costs. The proposed changes under Act 458 would limit or shift these fee recoveries for cases filed after September 1, 2027.
Economic & Business Losses
When landowners are unable to farm, ranch, drill, develop, or otherwise use the land until it is cleaned, they might also seek compensation for lost profits directly impacted by contamination. Costs to relocate operations or drill new water wells may also be included.
The Role of a Legacy Litigation Attorney
A Legacy litigation attorney guides landowners through complex oil and gas claims. They hire experts, gather pollution data, and build a strong case. Their experience in Louisiana’s Act 312 process is crucial to track deadlines, file paperwork, and argue evidence to meet the standard of proof.
Legacy litigation offers landowners a path to reclaim a clean, safe property. Acting before September 1, 2027, preserves your strongest legal rights under Act 312. You will lose key benefits once Act 458 takes effect.
