SRSNE OverviewSRSNE is a former solvent recovery facility in Southington, Connecticut. From 1955 to 1991, SRSNE recycled millions of gallons of solvents and other organic liquid wastes. After the solvents were distilled and reused, the unusable portions were disposed of in two unlined lagoons. In 1967, the lagoons were drained and covered with fill; subsequently, the waste was burned on site or disposed of offsite, but by the 1970s, the state put an end to those activities. The U.S. Environmental Protection Agency (USEPA) added the site to the Superfund list in 1983 and SRSNE installed a groundwater pump-and-treat system to begin cleanup in 1985. Then in 1991, operations at the facility were shut down.
SRSNE RemediationAccording to the REGENESIS Case Study: Colloidal Activated Carbon Acts As Permeable Barrier to Eliminate Risk, the long-term remedy included the following:
- Treating waste oils and solvents in an aquifer beneath the operations area by heating them in place.
- Consolidating and capping contaminated soil from impacted wetland and upland areas.
- Capturing and treating on-site contaminated groundwater exceeding federal or state drinking water standards.
- Monitoring natural degradation of the plume until groundwater cleanup levels are achieved.
- Monitoring natural degradation of the site-related chemicals in the bedrock.
- Putting in place restrictions on uses of the property and groundwater and monitoring groundwater.
- Maintaining the cap over the long term.
ResultsIn just 4 months, the treatment has resulted in a 50% decrease in PFAS levels. The remediation efforts have allowed for the development of an extension to the Rails to Trails greenway bike path, which runs through the capped area of the site. Continued improvements are expected over time as the impacted upgradient water flows through the PlumeStop application areas and toward the downgradient collection system. As environmental scientists and engineers, water pollution sometimes seems like an age-old environmental concern. But then we come across emerging contaminants. Emerging contaminants (or contaminants of emerging concern), put simply, are chemicals discovered in drinking water supplies that had not previously been detected. To make matters worse, their risk to human health is unknown. Due"Anchor QEA works with REGENESIS to Reduce PFAS in Groundwater"

Past ParticipantsThis past spring, Adam Carlson and Joe Smith visited Costa Rica through International Volunteer HQ’s IVHQ Construction and Renovation program, which connects international volunteers with community projects to improve, renovate, or newly construct buildings and infrastructure. Adam and Joe were placed at a non-profit organization dedicated to the prevention and treatment of drug addiction, re-education, and growth of character. The Hogares Crea location in San Jose houses about 20 girls, aged 18 and younger, and is supported daily by teachers, cooks, and other volunteers. For one week, Adam and Joe worked with a small team building the foundations for a laundry room shed and a building add-on to be used as a storage and office space. Last year, Jen Mott went all the way to Chiang Mia, Thailand, to volunteer at the Elephant Nature Park. The park is an elephant rescue and rehabilitation center that has been involved in dozens of rescues since the 1990s. The park also provides a natural environment for dogs, cats, buffaloes, and many other animals. With Anchor QEA’s support, I was able to fulfill a lifelong dream to volunteer with elephants. I now share my experience with others to continue the fight for the protection and ethical treatment of elephants. I am so grateful to Anchor QEA for supporting our volunteer and community service goals. – Jen Mott In 2016, Mike Conese traveled to Cusco, Peru, to teach English to local residents. As the largest town before Machu Picchu, the majority of Cusco’s economy is built on tourism. Being able to communicate with tourists allows many locals to be successful. Mike worked with teenage and adult students that worked in the tourism industry—cooks (for multiple-day walking tours), tour guides, small business owners, and even an engineer! The class consisted of students unable to pay for regular classes at Maximo Nivel, a local school that organizes these classes with the help of volunteers through IVHQ. As part of the program, Mike lived with a local couple and a handful of other volunteers from all around the world. Mike Werth traveled to Antigua, Guatemala, in 2015 with support from Anchor QEA’s Volunteer Grant Program. Guatemala experiences a tremendous amount of poverty, so, along with a group from Syracuse, New York, Mike worked with a church in Antigua called Iglesia Del Camino (IDC). IDC provides support in a number of different ways for the impoverished in rural communities surrounding Antigua, including building several small one-family homes in the town of Pastores, distributing water filters, and performing maintenance activities at several locations that provide food and education in rural areas (Campos de Suenos; Paso a Paso; and Kids Club). It was an extremely rewarding experience. I would recommend to anyone to take advantage of this program and volunteer your services in a part of the world you haven’t seen! – Mike Werth
Community Service at Anchor QEAService is one of Anchor QEA’s core values and, as such, we are passionate about community engagement and giving time, energy, and resources to have a positive impact in our world. Our Volunteer Grant Program is an extension of our local volunteer programs and charity drives. The program is meant to supplement—not replace—our local programs, so the grant-supported trips must occur outside of Anchor QEA office locations. Proposals for disaster relief volunteer programs in our office locations, however, are allowed. The program has offered several opportunities for Anchor QEA employees to help out those less fortunate, as well as immerse themselves in another culture and create lifelong friendships. We are truly fortunate to be part of a company that supports volunteering and service to our global community. Anchor QEA’s Volunteer Grant Program provides financial assistance to staff looking to help others outside their neck of the woods, allowing them to learn about another culture while volunteering their time to enhance the community or"Volunteer Grant Program"
