California wineries are facing common compliance challenges under the Statewide General WDR, from monitoring requirements and water softener brine separation to pond standards and compliance schedules.

In the new North Bay Business Journal article, “Navigating California’s Waste Discharge Requirements for Wineries,” Mehran Ebrahimi, PE, and co-author Donald Sobelman of Farella Braun + Martel take a closer look at these challenges and share practical considerations for wineries working toward compliance.

A new publication examines how microbial processes may influence the fate of CO2 in geologic carbon sequestration settings.

The article, Biotransformation Processes Relevant to Geologic Carbon Sequestration: Potential Implications for Environmental Fate, is published in Environmental Science & Technology and is authored by GSI experts Lisa J. Molofsky, Thomas E. McHugh, Danny Kingham, and Charles J. Newell, with contributions from Sven Lahme, Kelly M. McFarlin, Paul G. Koster van Groos, Frank E. Löffler, Louise Camenzuli, Leanne Walker, Sophie L. Nixon, and Trent A. Key.

The paper reviews how CO2-driven geochemical changes can alter microbial communities and trigger biotransformation processes that move carbon into mineral, gas, or organic phases. It also explores implications for both deep storage formations and nontarget environments such as shallow groundwater, the vadose zone, and marine systems, while identifying key knowledge gaps that affect long-term prediction of CO2 behavior.
