Water that is heavily loaded with H2S is referred to as?

Water that is heavily loaded with hydrogen sulfide (H2S) is referred to as "sour." This term is commonly used in the petroleum and natural gas industries to describe fluids that contain significant amounts of hydrogen sulfide, which is an undesirable and hazardous component.

Sour water typically contains H2S, which can have serious implications for both safety and processing. The presence of H2S indicates that the water can be corrosive to metals and necessitates careful handling due to its toxicity. Treating sour water often involves processes to remove H2S and other impurities to minimize environmental and health risks.

In contrast, the other terms listed describe different concepts. "Stripped" generally refers to the process of removing volatiles or contaminants from water, while "lean" typically describes a fluid with low concentrations of undesirable components. "Rich," on the other hand, often refers to fluids that contain high concentrations of desirable components, such as gas. Thus, the term "sour" accurately captures the nature of water that is heavily loaded with H2S.
