Quality water is critical to the work done across all industries, from food and beverage manufacturing to pharmaceutical research to power generation and beyond. The techniques for measuring and ensuring water quality are just as numerous as the applications—knowing when to use each method is a momentous challenge. Additionally, government regulations regarding drinking water, surface water, groundwater, and wastewater for industrial applications further underscore the need for scientists to be mindful of the purity of the water they work with. Perhaps most importantly, the health of our communities and the environment—the very world we work to improve—relies on maintaining pristine sources of water.
These resources aim to connect scientists with important resources for learning about water quality—so they can understand how consistent water quality can lead to better results in their work.
