San Diego Environmental Defense Lawyers for Dry Cleaning Contamination Sonal Chandawat October 19, 2026 Uncategorized 6 San Diego Dry Cleaning Litigation Lawyers A dry cleaning shop can face several environmental law issues. Old solvent tanks, buried drain lines, and decades-old spills don’t disappear when a lease ends. They sit in soil and groundwater, sometimes for thirty years, until a sale, a refinance, or a regulatory inspection brings them back to the surface. The San Diego dry cleaning litigation lawyers at Tropea McMillan LLP represent the businesses, property owners, and landlords named in these cases, whether the claim comes from a state agency, a neighboring property owner, or a tenant dispute over who pays for cleanup. We don’t represent the plaintiffs suing dry cleaners. We defend the operators, developers, and building owners on the other side of the case, and we’ve done it since 2004. If you’ve received a notice from a regulatory agency, been named in a toxic tort claim, or found yourself in a lease dispute tied to solvent contamination, you’re not the first business owner to face this, and you have options.

A closed or sold dry cleaning business still creates legal risk because the solvent it once used, perchloroethylene, or PERC, lingers in soil and groundwater long after the equipment is gone. Why PERC Sticks Around PERC doesn’t break down quickly, and older equipment wasn’t always built to contain it, so small leaks from decades ago can still show up in testing today. When the Risk Surfaces A sale, refinance, or Phase II environmental assessment often uncovers elevated PERC levels, and liability can attach to current owners, former operators, or landlords depending on the property’s history. How Does PERC Contamination Lead to Liability in San Diego? PERC contamination leads to liability once it moves past a property’s boundary and reaches soil, groundwater, or a neighboring structure, triggering regulatory or private legal action. Where San Diego Cases Tend to Surface Many older commercial corridors housed dry cleaners for decades, including stretches of El Cajon Boulevard, University Avenue, Convoy Street, and pockets of Kearny Mesa where retail and light industrial space sit close together. Buildings in these areas often predate current environmental standards, so plumbing and flooring weren’t designed to contain solvent spills. Who Gets Involved Once Contamination Is Confirmed The San Diego Regional Water Quality Control Board or County Department of Environmental Health may open an investigation. A neighboring property owner may bring a toxic tort claim over lost property value or cleanup costs. None of this means a business acted intentionally. It means responsibility now has to be sorted out. What Happens After an Agency Opens an Investigation? An agency investigation typically starts with a records request, followed by soil or groundwater sampling, and ends with either a closure letter or an order requiring further action. The Regional Water Board or County environmental health staff will usually ask for historical business records, prior tenant information, and any existing environmental reports before setting foot on the property. Sampling results then determine whether the case gets closed, monitored, or escalated into a formal cleanup order. The timeline for this process varies widely. Some cases resolve within months once initial data shows contamination is limited or already addressed. Others stretch across years, particularly when groundwater is involved and the agency wants ongoing monitoring wells to track how far contamination has traveled. Responding to the records request accurately and completely often sets the tone for everything that follows. This is why we recommend involving counsel before documents go out the door, not after an agency raises concerns about what was submitted. Legal Issues Our Clients Bring to Us Dry cleaning operators and property owners bring us five recurring legal problems: hazardous waste compliance, cleanup liability, toxic tort claims, lease disputes, and regulatory enforcement actions. Hazardous Waste Compliance Solvent storage, labeling, and disposal rules trip up even careful operators, especially when generator status changes over time as a business grows or shrinks. Cleanup Liability Regulators sometimes seek to recover investigation or remediation costs directly from a current or former owner, regardless of who caused the original contamination. Toxic Tort Claims Neighboring property owners occasionally file suit alleging that contamination lowered their property’s value or created a health concern, and these claims often rest on technical groundwater evidence. Lease Disputes Landlords and tenants frequently disagree over who pays for testing or cleanup, particularly when older leases never addressed environmental conditions. Enforcement Actions The Department of Toxic Substances Control and the Regional Water Board both have authority to issue orders requiring further investigation or remediation. Each situation carries its own evidence, timeline, and set of parties. Call Tropea McMillan LLP at (866) 977-8921 for a confidential consultation, and let’s talk about where your case stands. Who Investigates or Sues Over Dry Cleaning Contamination? Investigations and lawsuits over dry cleaning contamination usually come from one of three sources: a state or local regulatory agency, a neighboring property owner, or a landlord in a lease dispute. The Regional Water Quality Control Board and the County’s Department of Environmental Health both have authority to order investigations and require cleanup when PERC or its byproducts show up in soil or groundwater. The Department of Toxic Substances Control can also step in, particularly when hazardous waste handling is part of the concern. Private lawsuits tend to follow a different path. A neighboring business or homeowner who discovers contamination on their own property may sue for damages, arguing that migration from a dry cleaning site lowered their property’s value or created a nuisance. These cases often hinge on technical groundwater flow data and historical property records, which means the strength of a defense depends heavily on how thoroughly that evidence gets reviewed. Lease and Property Disputes Between Landlords and Tenants Landlords and dry cleaning tenants disagree over who pays for testing and cleanup because older commercial leases rarely spelled out responsibility for environmental conditions, leaving both sides to argue over conduct, timing, and the building’s history. What Drives These Disputes A landlord may argue the tenant’s operations caused the contamination. A tenant may point to prior occupants or the building’s age and construction. Neither side’s position is automatically stronger without reviewing the lease and property records closely. Why Lease Language Matters Indemnification clauses, environmental disclosure terms, and even the date a lease was signed can shift financial responsibility from one party to the other. Many leases signed decades ago never addressed environmental conditions at all, since PERC contamination wasn’t a widely recognized issue at the time. Without clear language, a court may have to weigh conduct and industry practice instead. Where This Shows Up Locally Property owners in older San Diego commercial buildings, particularly in neighborhoods like North Park, City Heights, and Hillcrest, sometimes discover contamination only when a new tenant’s due diligence uncovers it, drawing in everyone who has held an interest in the property over the years. How Do Environmental Assessments Affect Property Sales and Redevelopment? An environmental assessment affects a property sale or redevelopment project by determining whether a lender, buyer, or city permitting office will move forward without additional testing or cleanup conditions attached. The Assessment Process A Phase I environmental site assessment reviews historical records and prior uses of a property. If that review flags a former dry cleaning tenant, a Phase II assessment with soil borings usually follows. Commercial deals across San Diego, including redevelopment projects in areas like Mission Valley and Sorrento Valley where older retail centers are being repositioned for mixed-use or office space, routinely require this step before closing. What Happens After a Positive Result A positive Phase II result doesn’t automatically end a deal, but it does change the negotiation. Buyers may ask for a price reduction, an escrow holdback, or a seller commitment to remediate before or after closing. Some owners pursue California’s Voluntary Cleanup Program, working with state oversight to address contamination on a defined timeline in exchange for a formal closure letter. Why Timing Matters A Phase II assessment and any follow-up sampling can add weeks or months to a transaction, and lenders often won’t fund a deal while a regulatory question remains open. Why Retaining Counsel Early Changes the Outcome Retaining counsel early changes the outcome because environmental cases are built on technical evidence, and the interpretation of that evidence often determines who pays and how much. A soil sample result, a groundwater flow model, or a historical aerial photograph can all be read multiple ways, and the party that engages qualified experts and legal counsel first tends to shape the narrative that regulators or courts rely on later. Business owners sometimes wait to see how serious a regulatory letter or a neighbor’s complaint really is before calling anyone. That delay can work against you. Early involvement lets us review the underlying data, identify weaknesses in the other side’s assumptions, and, where appropriate, negotiate directly with a regulatory agency before a matter escalates into formal litigation. We’ve found that businesses who bring us in at the notice stage, rather than after a lawsuit is filed, generally have more room to manage the outcome. Our Experience Defending San Diego Businesses Tropea McMillan LLP has represented corporations, small businesses, developers, and property owners in environmental defense matters since 2004. Our attorneys have earned Rising Stars recognition from Super Lawyers, a distinction based on peer evaluation and case results rather than self-reported credentials. We built our practice around one side of these disputes: defending the businesses and property owners named in environmental claims, not bringing claims against them. That focus means our attorneys spend their time working with the same regulatory agencies, the same categories of technical evidence, and the same procedural rules that come up again and again in dry cleaning contamination cases. A knowledgeable dry cleaning litigation attorney who has handled PERC-related disputes before knows which arguments regulators find persuasive and which expert reports tend to hold up under scrutiny. Our approach usually starts with an independent review of the sampling data and site history, since the assumptions built into an agency’s initial findings aren’t always the last word, and a closer look sometimes reveals a stronger position than a client expected going in. Frequently Asked Questions About Dry Cleaning Environmental Law Issues in CA What should I do if I get a letter from the Regional Water Quality Control Board? Read the letter carefully, note any response deadline, and contact a defense attorney before replying. Agencies often request specific documents or testing, and how you respond in the first thirty days can affect the scope of any investigation that follows. Can I be held responsible for contamination caused by a previous tenant or owner? It depends on your role, when you acquired the property, and what the lease or purchase agreement says about environmental conditions. Current owners and operators can sometimes share liability with prior parties, which is why a full review of property history matters early on. How much does it cost to retain a defense attorney for an environmental claim? Costs vary based on the complexity of the case, the number of parties involved, and whether the matter stays administrative or moves into litigation. We discuss fee structures directly during a confidential consultation so you know what to expect before deciding how to proceed. What happens if a neighboring property owner sues over groundwater contamination? A toxic tort lawsuit typically requires the plaintiff to prove the contamination came from your property and caused measurable harm, which opens the door to disputing both the source and the damages claimed. These cases often turn on groundwater modeling and historical records, so building a strong technical defense early is one of the most useful steps you can take. Do I need a lawyer if I’m just selling a property with old dry cleaning use? Selling a property with a history of dry cleaning use often triggers environmental disclosure requirements and can affect financing or closing timelines if contamination is found during due diligence. Having counsel review the transaction before you list the property can prevent surprises that delay or derail a sale. SHARE THIS POST
