What type of water quality problems are commonly observed in groundwater?

Groundwater quality can often be compromised by specific issues that are frequently encountered. One notable problem is high iron content, which can lead to staining of fixtures and laundry, and an unpleasant metallic taste in the water. This occurs because iron can be naturally present in the geological formations that ground water flows through.

Additionally, the potential for radon in groundwater is significant. Radon is a colorless, odorless radioactive gas that can be released during the natural decay of uranium found in soil and rock. When groundwater comes into contact with these uranium-bearing formations, radon can dissolve into the water. This is a concern because radon is also linked to health risks if inhaled or ingested over prolonged periods.

Other options present problems that are either less common or do not typically characterize groundwater. For example, hard water does not suggest low mineral content; in fact, it signifies the presence of higher levels of minerals, which is not usually the primary issue. High turbidity correlates more with surface water due to sediment and debris, while excessive chlorine and fluoride levels are more relevant to treated water systems rather than naturally occurring groundwater.
