Observationbrunnen

An observation well, also known as a piezometer, is a well or borehole constructed to monitor groundwater levels, quality, or both. These wells are typically of a smaller diameter than production wells and are designed specifically for measurement purposes. They are drilled into aquifers to provide direct access to the groundwater.

The primary function of an observation well is to collect data on the behavior of an aquifer over time. This data can include the static water level, which indicates the natural elevation of the groundwater table, and changes in water levels due to pumping, recharge, or natural fluctuations. In some cases, observation wells are equipped with sensors to continuously record water level data, which is then transmitted for analysis.

Beyond water levels, observation wells can also be used to monitor groundwater quality. Samples can be collected from these wells to assess parameters such as salinity, pH, temperature, and the presence of contaminants. This is crucial for understanding the impact of human activities or natural processes on groundwater resources. Observation wells are often installed in clusters to provide a comprehensive understanding of groundwater flow paths and contaminant plumes. They are essential tools for hydrogeologists, environmental scientists, and water resource managers in assessing aquifer health and sustainability.
