Understanding the EPA’s Latest Proposed Drinking Water Contaminant Monitoring Rule, Published in Law360

September 01, 2026 — Gordon Rees Scully Mansukhani
The U.S. Environmental Protection Agency’s (EPA) proposed Sixth Unregulated Contaminant Monitoring Rule (UCMR 6) represents another step in the federal government’s ongoing effort to identify and evaluate emerging contaminants in drinking water. The proposal would require certain public water systems to monitor and report on 30 unregulated drinking water contaminants from 2028 through 2030, while generating occurrence data that could inform future regulation and affect environmental, commercial, litigation and risk assessments. In an article published by Law360, Gordon Rees Scully Mansukhani Senior Counsel, Ayodeji Ayolola, analyzes the scope and practical implications of UCMR 6, including the contaminants selected, the proposed monitoring requirements for public water systems, and the EPA’s continued focus on PFAS and related organofluorine compounds. The article also touches upon the potential significance of publicly available monitoring data for businesses and property stakeholders. Read the full story...

Sausage-Making Often Relies on the Good Sense of the Chef Rather than the Recipe

June 23, 2026 — Garret D. Murai - California Construction Law Blog
Even for lawyers, the rules governing litigation can get complex and convoluted. Does something need to be filed? What needs to be filed? When is the deadline for filing? Simple questions with not always with straightforward answers. This was the case in R & J Sheet Metal, Inc. v. W.E. O’Neil Construction Co. of California, 111 Cal.App.5th 878 (2025), which involved sheet metal panels lost when they fell into the Port of Long Beach harbor. Read the full story...

Potential Gap in Workers Compensation Immunity Statutory Framework

June 02, 2026 — David Adelstein - Florida Construction Legal Updates
Workers compensation insurance is important. As an owner, you want to ensure the contractors you hire have workers compensation insurance. Assuming you hire a contractor that is statutorily exempt from workers compensation, you want to make sure, no exception, that any subcontractor that is hired has workers compensation insurance. (Regardless, you always want subcontractors to have workers compensation insurance.). In construction, the prime contractor serves as the “statutory employer” for purposes of workers compensation insurance. With workers compensation comes workers compensation immunity.

From CERCLA to Drinking Water: D.C. Circuit’s PFAS Ruling Enters a Second Regulatory Fight

October 06, 2026 — Ashleigh K. Myers, Amanda G. Halter & Jillian Marullo - Gravel2Gavel Construction & Real Estate Law Blog
On August 18, 2026, a unanimous panel of the U.S. Court of Appeals for the D.C. Circuit upheld EPA’s designation of perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS) as hazardous substances under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA or Superfund). In Chamber of Commerce of the United States v. EPA, the court rejected challenges to EPA’s interpretation of CERCLA Section 102(a), the adequacy of its notice and comment process, its analysis of costs and benefits, and its decision to proceed despite uncertainty about future response actions and costs. This decision is already being invoked in a separate D.C. Circuit challenge to EPA’s 2024 PFAS drinking water rule promulgated under the Safe Drinking Water Act (SDWA). Six days after the CERCLA decision, respondent intervenors cited it as supplemental authority in American Water Works Association v. EPA, No. 24-1188, ahead of oral argument scheduled for September 18, 2026. The Chamber of Commerce decision may assist the respondent intervenors on certain notice and comment and economic analysis arguments, but its significance should not be overstated. The principal challenges to the standards for the four PFAS subject to EPA’s Hazard Index-based maximum contaminant level (MCL) turn on requirements specific to the SDWA, and EPA itself now agrees that those provisions were promulgated through an unlawful process.

Federal Bid Protest Standard of Review and Disparate Treatment with Ratings

August 16, 2026 — David Adelstein - Florida Construction Legal Updates
A recent decision out of the Federal Claims Court explains the post-award bid protest standard of review. In Massman Construction Co. v. U.S., 2026 WL 1971985 (Fed.Cl. 2026), a protestor brought a post-award bid protest after the Army Corps of Engineers awarded the contract to another contractor. The protestor argued that the Army Corps (government) acted irrational in its evaluation through disparate treatment. The Court of Federal Claims agreed and remanded for the Army Corps to “either justify this disparity or explain why [awardee’s] lower-priced, but technically inferior proposal provides the best value to the government.” Massman Construction, supra at *1.

"Resilient Rebuild Hub" Helps Wildfire-Impacted Homeowners Build Back Stronger

September 21, 2026 — California Nevada Cement Association
NEWPORT BEACH, Calif., Sept. 21, 2026 /PRNewswire/ -- When homeowners in a fire-ravaged Pacific Palisades neighborhood banded together last year to rebuild with fire-hardened materials rather than standard wood framing, they weren't just rebuilding houses: they were rewriting the playbook for how California communities can rebuild after wildfire. Today, the Building with Resilience effort is making that playbook available to every homeowner facing the same decision with the launch of its new Resilient Rebuild Hub for exploring fire resistant, non-combustible construction options. The Resilient Rebuild Hub helps homeowners understand options for fire-resistant, concrete-based construction and connect with architects, engineers, and contractors who can build them. This includes six noncombustible building systems:

• Insulated Concrete Forms (ICF): stackable, high-density foam blocks filled with concrete which save 20-50% on monthly heating and cooling costs, reduce outside noise by up to 80%, offer exceptional earthquake performance and 4-hour fire resistance rating.
• Insulated Composite Concrete Forms (ICCF): similar formwork to ICF construction with composite materials that enhance strength, simplify installation, and improve long-term performance.
• Concrete Masonry: strong, durable wall systems used for decades across California and the U.S.
• Precast Insulated Sandwich Panels: a complete building enclosure system consisting of two layers of concrete separated by a continuous layer of rigid insulation.
• 3D Shotcrete: air-sprayed concrete for strong, fast, and versatile wall systems that enable a high degree of artistic freedom together with unparalleled fire resistance.
• 3D Concrete Printing: the cutting edge of residential construction, a large-scale robotic 3D printer "squeezes" a specialized concrete mixture layer by layer to allow for organic, curved designs that are often too expensive or impossible to build with traditional methods. The Resilient Rebuild Hub is available now at buildingwithresilience.com/how-to-build. Each part is free to access and includes case studies, technical resources, and a directory of architects, engineers, and contractors experienced in each building method. CNCA is a not-for-profit organization committed to developing sustainable and economical construction solutions for California and Nevada with an emphasis on the use of cement and concrete.

  Trend Continues Where Unlicensed Contractors Have No Recourse

  July 13, 2026 — David Adelstein - Florida Construction Legal Updates
  There’s been a recent trend in Florida case law that has figuratively “killed” unlicensed contractors. Here’s another one. The moral to this trend and case is simple: make sure you have the proper licenses prior to serving as a contractor under Florida law. Trying to be cute, as seemed to be the situation in this case with a creative argument, is not an argument that will carry the day and your resources will be devoted to being creative versus the ultimate merits of the dispute. In Ramindesign, LLC v. Skarzynski, 2026 WL 1649571 (S.D.Fla. 2026) an owner of real property hired a company to design and construct a spec home on the property. The company and its owner were NOT licensed contractors. The contract stated the company was serving as a “spec developer” and referred to it as the contractor throughout the contract. Other than this, the contract was set up as a cost plus a fee. Read the full story...
