Wastewater from our facilities is managed and treated to meet regulatory standards and minimize environmental impacts. We operate wastewater-treatment plants at many of our production and research facilities. Approximately 65 percent of the wastewater from our manufacturing plants is treated on-site before being discharged to rivers or other surface water bodies. The remaining 35 percent is sent to local municipal wastewater-treatment facilities that have the technology and capacity to treat our wastewater.
