What monitoring system is required for subsurface impounds to ensure safety?

The requirement for groundwater monitoring systems for subsurface impounds is critical to ensure safety because these impounds can contain hazardous materials or pollutants that might leach into the groundwater. Monitoring groundwater helps to detect any potential contamination early, allowing for timely remediation actions to prevent harm to the environment and public health.

Groundwater is a vital resource, and protecting it from potential pollutants is essential in maintaining safe drinking water standards and protecting ecosystems. Continuous monitoring provides data on the quality of the groundwater over time, ensuring that any changes can be quickly addressed.

In contrast, although temperature monitoring, air quality monitoring, and soil testing contribute to environmental safety, they do not provide direct insight into the risks associated with subsurface impounds like groundwater monitoring does. Each of those options serves a different purpose, but they do not focus specifically on the potential for harmful substances to migrate from impoundments into the groundwater.
