Many public waters systems implement treatment equipment to meet regulations, address emerging contaminants of concern, or remove nuisance contaminants that negatively impact user experience. Our products are most commonly treating water for the following contaminants:
- Disinfection byproducts (TTHM, HAA5)
- Dissolved gases
- Hydrogen sulfide
- Hexavalent chromium
- Per- and polyfluoroalkyl substances (PFAS)
- Total and dissolved organic carbon (TOC/DOC)
- Total dissolved solids (TDS)
- Total suspended solids (TSS)
- Turbidity and associated pathogens
- Volatile organic compounds (VOC)
Per- and polyfluoroalkyl substances (PFAS) are prevalent in the environment due to their widespread use in various industrial and consumer products. State and pending federal regulations in the United States require the removal of several types of PFAS, including perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), from drinking water sources. As a result, many public water systems must add previously unnecessary treatment equipment.
When addressing PFAS, it is important to develop a comprehensive treatment strategy that considers the total water quality. An integrated approach with pre-treatment will often deliver better water while reducing life cycle costs. Contact us to discuss possible treatment options for your specific PFAS application.
The Build America, Buy America (BABA) Act became law in November of 2021 with the enacting of the Infrastructure Investment and Jobs Act (IIJA). It requires that all products with few exceptions incorporated into federally funded infrastructure projects be produced in the United States with separate definitions for iron and steel products, manufactured products, and construction materials.
Kurita America manufactures all equipment systems in the United States, and our existing supply chain supports the 55% domestic component content required for BABA compliance. Contact us to discuss your project and understand how to navigate these new requirements.
