Lead: Division of Drinking Water

Lead can enter drinking water when plumbing materials containing lead corrode, especially if the water is highly acidic or contains a low mineral content. The most common sources of lead in drinking water are lead pipes, faucets, and fixtures. Lead service lines that connect a building or house to the water main can also be …

Lead in Air

Lead is a toxic metal that was once used regularly in motor fuel, paint, ceramics, glassware, and other consumer products. The phase-out of leaded gasoline significantly reduced vehicle emissions and lead levels in the environment, but it is still used in some aviation fuels and used or produced in a variety of industrial processes. The …

PFAS Workgroup

The Department of Environmental Quality (DEQ) formed a workgroup in spring 2019 to evaluate the potential for environmental contamination in Utah from Per- and Polyfluoroakyl Substances (PFAS). PFAS are used in many consumer products and industrial processes to repel oil, water and grease, reduce friction, and resist temperature extremes. These compounds do not break down …

Health Effects of PFAS

Concerns about the potential public health hazards of human exposure to per- and polyfluoroalkyl substances (PFAS) continue to increase as scientists learn more about these chemicals. The large number of PFAS compounds–over 4,000–present considerable challenges. The available toxicity and epidemiology data are currently limited to the evaluation of only a few chemicals. Different PFAS compounds …

Human Exposure to PFAS

People can be exposed to PFAS from a variety of different sources. Most people are exposed to PFAS from drinking water and eating food that contains these chemicals. Drinking water can be a source of exposure in communities where these chemicals have contaminated water supplies. Such contamination is typically localized and associated with a specific …

Petroleum

Black and Yellow Wax Black and yellow waxes are thick crude oils with a higher paraffinic content than most crude oils found in North America. These waxy crudes are viscous and have a high pour point, which means they become semi-solid at lower temperatures. The process for refining waxy crudes presents some challenges. Although black …
