Water Quality Testing and Treatment Systems for Pharmaceuticals

Nearly half of all Americans take one or more prescription drugs, with the percentage soaring to 85 percent for persons aged 60 and above (myself included). Water is the most widely used substance in the production, formulation, and packing of myriad pharmaceuticals, which are compounds manufactured for use as medicinal drugs. Given the public health importance and global footprint of pharmaceuticals, including antibiotics, there are extensive testing and safety requirements to control the quality of water used throughout the manufacturing processes. This article explains how water impacts the medicines you take, and what lengths are taken to keep them safe.

Addressing Water Scarcity: Future Plans for U.S. Water Reuse

Although snow-capped mountains are visible from much of Denver where I live, Colorado is one of 40 states that anticipate water scarcity challenges in the next decade. The Water Quality & Health Council has written dozens of articles on drinking water quality and the public health imperatives of safe treatment, disinfection, storage, and distribution. Yet water quality goes hand in hand with water availability, use, conservation, and increasingly—water reuse. A newly launched report and national effort led by the U.S. Environmental Protection Agency (EPA), the Draft National Water Reuse Action Plan, is making the news. The plan succinctly puts these needs and connections into perspective: “Safe and reliable water supplies for human consumption, agriculture, business, industry, recreation, and healthy ecosystems are critical to our nation’s communities and economy.” Water scarcity challenges are also global; two of the United Nations’ Sustainable Development Goals emphasize water reuse.
