Suing a Pennsylvania Fracking Company for Well Water Contamination: Testing, Liability, and Costs

Current as of: September 15, 2026 Fracking & Marcellus Shale Environmental Law Pennsylvania
💧
If a Marcellus Shale fracking operation contaminates your private well in Pennsylvania, state law presumes the drilling company is liable if the well is within 2,500 feet of the site. You can seek financial compensation for property damage and water replacement.

Living in rural Pennsylvania often means relying on a private well for your family's drinking water. However, with the rapid expansion of Marcellus Shale natural gas drilling, thousands of property owners in counties like Susquehanna, Washington, and Bradford have faced a nightmare scenario: suddenly turning on the tap to find discolored, foul-smelling, or even flammable water. When a fracking company's operations contaminate your groundwater, it can destroy your property value and pose severe health risks. Fortunately, Pennsylvania law provides strict mechanisms for landowners to hold these massive energy corporations accountable.

Filing a toxic tort lawsuit against a multi-billion dollar gas company is a complex legal battle. The company will aggressively defend itself, often claiming the water was 'always like that' or that the contamination came from another source. To win, you need to understand how liability works under state law, specifically the protections granted by Act 13. By hiring an experienced local environmental lawyer from our directory, you can level the playing field, secure clean water for your family, and demand the compensation you deserve.

The PA DEP 'Presumption of Liability' Under Act 13

One of the strongest legal tools available to Pennsylvania landowners is found in the state's oil and gas law. Under 58 Pa.C.S. § 3218 (often referred to as Act 13), there is a 'presumption of liability' placed on the drilling company. If your private water supply becomes contaminated within one year of drilling, altering, or stimulating a gas well, and your property is located within 2,500 feet of that well, the law presumes the fracking company caused the pollution.

This means you do not initially have to prove exactly how the chemicals leaked; the burden is on the gas company to prove they did not cause it. If the company cannot disprove their involvement, the Pennsylvania Department of Environmental Protection, Harrisburg can force the operator to restore or replace your water supply with an alternative source of adequate quantity and quality.

Tracing Specific Contaminants in Your Water

Fracking requires injecting millions of gallons of water, sand, and proprietary chemicals deep underground at extremely high pressure. When well casings fail or waste pits leak, specific fingerprints are left in local aquifers.

Methane Migration

Methane is the primary component of natural gas. When drilling cracks the bedrock improperly or a steel casing is poorly cemented, methane can migrate upwards into drinking water aquifers. While methane is not toxic to drink, it makes the water bubble and can gather in confined spaces (like your basement or well house), creating a catastrophic explosion hazard.

Heavy Metals (Barium/Strontium)

The Marcellus Shale formation contains naturally occurring toxic heavy metals deep within the earth. The violent fracking process forces these metals, particularly barium, strontium, and arsenic, up toward the surface. Ingesting high levels of barium can cause dangerous spikes in blood pressure and organ damage.

Fracking Fluid Chemicals

Gas companies use complex chemical cocktails to reduce friction and kill bacteria down the wellbore. If you suspect these specific fluids have leaked into your water, you must file the Form Online, Pennsylvania, Department of Environmental Protection, Environmental Complaint Form with your local regional office, such as the Pennsylvania Department of Environmental Protection, Williamsport or the Pennsylvania Department of Environmental Protection, Pittsburgh.

The Costs of Hiring Hydrogeologists

To successfully sue a fracking company, your lawyer will need to hire expert witnesses, specifically hydrogeologists. A hydrogeologist studies the movement of groundwater and can scientifically prove that the contaminants in your well originated from the nearby drill pad. Because gas companies employ armies of scientists, your legal team must match their expertise.

Hiring a qualified hydrogeologist for testing, data modeling, and courtroom testimony can easily cost between $15,000 and $40,000. Fortunately, most environmental and toxic tort lawyers in Pennsylvania work on a contingency fee basis. This means the law firm advances the costs for these highly expensive experts, and you only pay the lawyer a percentage of the final settlement or verdict if you win the case.

Timeline for Filing a Toxic Tort in PA

In Pennsylvania, the statute of limitations for property damage and personal injury claims is generally two years under 42 Pa.C.S. § 5524. However, water contamination can take months or years to become physically noticeable. Therefore, courts apply the 'discovery rule.' The two-year clock begins ticking on the day you knew, or reasonably should have known, that your water was contaminated and that the fracking company was likely responsible.

Major precedents, such as the highly publicized Dimock water cases seen in Ely v. Cabot Oil & Gas Corp., 38 F. Supp. 3d 518 (M.D. Pa. 2014), demonstrate that pursuing a fracking company through the federal or state courts can take 3 to 7 years to reach a final jury verdict. Documenting your damages early is critical to surviving this lengthy legal marathon.

Frequently Asked Questions (FAQ)

What should I do if my water suddenly smells like chemicals?

Stop drinking the water immediately. Contact the PA DEP to file an official complaint and request an emergency investigation, and then consult an environmental attorney before signing any documents given to you by the gas company.

Can the gas company just buy my property?

Yes. In many contamination cases, the parties reach a confidential settlement where the fracking company purchases the ruined property at its pre-contamination value, allowing the family to move somewhere safe.

Will the state test my water for free?

If you file an official complaint and the PA DEP suspects a violation, they will dispatch an investigator to test your water. However, for a private lawsuit, your lawyer will still need to hire independent experts to verify the state's findings.

Does the 2,500-foot rule apply to older gas wells?

The presumption of liability under Act 13 (2,500 feet and one year) applies to unconventional wells (deep horizontal fracking). Older, conventional shallow wells have a smaller presumption zone of only 1,000 feet and six months.
