🔬 Future scientists are making a difference today!

This , we’re celebrating Ashley Rodriguez & Molly Ciafone, two interns spending their summer learning alongside the scientists in DTSC’s Environmental Chemistry Laboratory.

➡️ Ashley joined through the Association of Public Health Laboratories Internship Program, which provides college students with hands-on laboratory experience, professional training, and opportunities to explore careers in public health laboratory science. In just 2 months, Ashley has mastered sample management and is now shadowing scientists in the metals laboratory, learning about quality control, laboratory instrumentation, and standardized analytical methods. 👏👏👏

➡️ Molly, a recent high school graduate, sought out DTSC after learning about our work protecting communities from toxic substances. Inspired by DTSC’s outreach efforts, she joined our Environmental Chemistry Laboratory before beginning her studies at UC Irvine this fall. Her curiosity, enthusiasm, and commitment to environmental and public health represent the future of California’s scientific workforce. 🧠💫🙌

At DTSC, internships provide more than laboratory experience—they help inspire and prepare the next generation of scientists dedicated to protecting California’s people and environment.

🔬 Celebrating National Intern Day by recognizing the next generation of environmental scientists!

This , we’re proud to recognize Emerald Kwang, an Association of Public Health Laboratories Fellow, whose work is helping protect California’s people & environment.

After first joining through the APHL Internship Program, Emerald continued her journey as a Fellow, gaining hands-on experience while contributing alongside our Environmental Chemistry Laboratory scientists. The APHL Fellowship Program provides early-career public health professionals with one-year placements to build technical expertise and prepare for careers in public health laboratory science.

At DTSC, Emerald performs many of the same responsibilities as our full-time scientists, including analyzing toxic metals in environmental samples using EPA analytical methods. Her work helps generate the high-quality scientific data that supports environmental decision-making across .

We’re grateful for Emerald’s dedication and excited to see where her career takes her next!

A major milestone is underway at the Lava Cap Mine cleanup site! 🎉

Today joined U.S. EPA Pacific Southwest Region, the U.S. Army Corps of Engineers, and state & local partners to celebrate the start of construction on a new semi-passive water treatment system --designed to treat water flowing from the former mine.

Once complete, the system will help Little Clipper Creek watershed, safeguard downstream drinking water supplies, and reduce risks to the surrounding community.
