Veolia announces test results for PFAS waste incineration

Veolia (Port Arthur, Texas) has published the results of comprehensive testing of the incineration of PFAS compounds. According to Veolia, tests demonstrated that high temperature incineration is a proven and reliable disposal solution for high concentrations of targeted PFAS, destroying greater than 99% of targeted substances, including up to 99.9999% of PFOS and PFHxS. The two-phased study was conducted at Veolia’s hazardous waste incinerator in Port Arthur in July and October 2024 by a third party provider. Testing evaluated thermal treatment of AFFF fire fighting foam, PFAS-contaminated soil, and spent carbon water treatment media in alignment with the EPA’s Interim Guidance on the Destruction and Disposal of PFAS of April 8, 2024. 

 

Tetra Tech reports strong Q2 results

Tetra Tech Inc. (Pasadena, Calif.) announced that in the second quarter ended March 30, 2025, revenue increased 6% year over year to $1.322 billion. Year-to-date, revenue increased 11% year over year to $2.74 billion.

Jacobs evaluates PFAS in biosolids

To support utilities and biosolids producers, Jacobs (Dallas) has evaluated several biosolids products from 15 full-scale facilities for a new research study published in the Journal of Water Process Engineering. According to a post on Jacobs’ website, the samples, derived from non-industrially impacted sources, underwent composting (aerobic), thermal drying and high temperature pyrolysis. The study analyzed final PFAS concentrations and assessed the effectiveness of each treatment method in reducing or eliminating PFAS from the initial feed solids. Jacobs measured 24 PFAS types. The study will provide utility planners, operators, and others with a deeper understanding of how PFAS enter biosolids and the technologies available for treatment.

New RO plant boosts water resilience in Lower Keys

The Florida Keys Aqueduct Authority, Florida Gov. Ron DeSantis, and project partners celebrated the opening of the $47 million Kermit H. Lewin Stock Island Reverse Osmosis (RO) Facility in May. Carollo Engineers (Walnut Creek, Calif.) designed the plant with support from key subconsultants Control System Consulting and ADS Engineering. The new facility doubles capacity from 2 million to 4 million gallons per day. The upgraded plant features advanced RO technology and achieves approximately 45% water recovery—the proportion of seawater converted to freshwater—through single-stage RO units and incorporates degasification and chemical treatment processes with post-treatment stabilization. These innovations contribute to a 50% reduction in energy consumption compared to the previous facility, despite doubling its production capacity. This is particularly important given the energy-intensive nature of desalination processes.

EPA to extend compliance time for PFOA, PFOS in drinking water

U.S. Environmental Protection Agency (EPA) announced it would keep the current National Primary Drinking Water Regulations for perfluorooctanoic acid (PFOA) and perfluorooctane sulfonic acid (PFOS). However, the agency intends to extend compliance deadlines to allow drinking water systems more time to develop plans for addressing PFOA and PFOS and implement solutions, including a proposal to extend the compliance date to 2031. EPA also announced its intent to rescind the regulations for PFHxS, PFNA, HFPO-DA (commonly known as GenX) and the Hazard Index mixture of these three plus PFBS. EPA plans to issue a proposed rule this fall and to finalize this rule in spring 2026.

 

Seagrasses are unsung heroes of climate mitigation

The world’s seagrasses possess a remarkable ability to capture and store vast amounts of carbon, according to a global study published in Nature Communications. Led by Florida International University scientists in partnership with Conservation International and International Blue Carbon Institute, the study predicts that protecting at-risk seagrass meadows could avert climate damages valued in excess of $200 billion by preventing the release of 1.2 billion tons of carbon pollution. Despite covering only 2% of the ocean floor, vegetated coastal ecosystems store nearly half of the organic carbon buried in ocean sediments. This comprehensive study draws on 3,240 seagrass and soil samples spanning 61 countries. “Found on every continent except Antarctica, these crucial ecosystems are the critical foundation for coastal communities, yet significantly understudied and undervalued,” noted Emily Pidgeon, co-author of the study and vice president at Conservation International.
