What is a bailer commonly used for in water monitoring?

A bailer is a commonly used tool in water monitoring specifically designed to remove water from monitoring wells. This device allows technicians to collect groundwater samples effectively by removing specific volumes of water from the well, which is critical for testing and analyzing water quality conditions.

When the bailer is lowered into the well, it collects water as it descends, and when it is pulled back up, it brings the water sample to the surface for further analysis. This method provides an efficient way to obtain samples from specific depths within the well, ensuring that the samples are representative of the groundwater present. Understanding the function of a bailer is essential for proper water monitoring procedures, enabling accurate data collection for environmental assessments.
