Evoqua Water Technologies Names Samsung Austin Semiconductor Winner of Annual Water Sustainability Award

Evoqua Water Technologies (NYSE: AQUA), an industry leader in mission-critical water treatment solutions, today named Samsung Austin Semiconductor, LLC as the recipient of the 2022 Evoqua Water Sustainability Award. The award recognizes Evoqua customers for their excellence in water stewardship, including those companies using new or existing technologies in innovative, sustainable ways, as well as companies that have made significant strides in water reduction.

Samsung Austin Semiconductor, LLC, a subsidiary of Samsung Electronics Co., Ltd., has been recognized for Evoqua's annual sustainability award after demonstrating noteworthy enhancements in waste reduction and water conservation for its semiconductor manufacturing facility in Austin, Texas. Samsung Austin Semiconductor is committed to environmental excellence in the operation of its advanced manufacturing operations.

"The Evoqua Sustainability Award proudly celebrates the dedication and innovation of customers deploying technologies and operating practices to reach their sustainability goals," said Ron Keating, Evoqua's Chief Executive Officer. "Samsung Austin Semiconductor's achievements in reducing water and waste in its operations have made it an exemplary company, and we are honored to be part of its sustainability journey."

"Samsung Austin Semiconductor has made numerous strides to address our environmental commitment," said Jeff Smith, Vice President of Infrastructure Technology at Samsung Austin Semiconductor. "It is an honor to receive this award, and we'll continue our efforts to be a leader and steward of our environment in all of our operations and business."

The Austin facility recently upgraded its treatment solution to remove and recover copper from its wastewater prior to discharge in a more environmentally friendly manner. Following a successful pilot project, Evoqua worked with the facility to design and install a full-scale wastewater ion exchange solution based upon collaborative engineering solutions, providing the plant with a simplified and sustainable treatment system.

The system design incorporates many benefits, including:

• Elimination of an estimated 1.5 million pounds of sludge sent to the landfill annually
• Removal of lime slurry equating to an estimated 1.5 million gallons of water conserved per year
• Reducing approximately 1,400 tons of chemicals per year
• Optimizing its carbon usage rate, thereby reducing the number of service visits required and the amount of carbon media consumed by an estimated 10,000 pounds per year
• Recovery of copper from the wastewater stream, reducing approximately 15,000 pounds of copper being sent to landfills annually
• Improving employee safety by reducing the handling of chemicals during the treatment process

Evoqua employees nominate sustainable companies from its customer base for exhibiting excellence in water stewardship, community impact, water and energy efficiency, and environmental protection. The award is given on World Water Day, which occurs annually on March 22. Other finalists included Orange County Water District and Atlantis Dubai.

Due to per- and polyfluoroalkyl substances (PFAS) being detected in groundwater basins, Orange County Water District (OCWD) was forced to import its water, which could be costly and difficult to source particularly in drought conditions. To address the issue, OCWD installed a state-of-the-art PFAS treatment system at their City of Fullerton Kimberly Well 1A Treatment Plant. The installation included an Evoqua ion exchange treatment system to remove the harmful contaminants and provide safe and reliable drinking water to its residents. The system meets all state and federal drinking water standards while providing a sustainable and more cost-effective water source for the City and its residents.

In June 2021, Atlantis Dubai launched the Atlantis Atlas Project, centered around protecting and preserving the natural world through awareness and education, including acting responsibly to conserve energy, water, and natural resources. To reduce potable water consumption, Atlantis replaced all of its sand filters with Evoqua's Defender® regenerative media filters in its freshwater systems, including its swimming pools, waterpark, and spa. This new system provides the resort with exceptional filtration capabilities in addition to significant water and energy savings compared to sand filtration.
