Water Quality Crisis Unveiled in Local Well Testing

In a recent government meeting, officials discussed the findings from extensive testing conducted on a local well, referred to as Well Twelve, which has raised concerns regarding water quality and its impact on nearby wells. The testing, aimed at assessing the well's capacity and the presence of contaminants, revealed significant issues related to high levels of iron and arsenic in the water sourced from upper aquifer zones.

During the meeting, it was reported that initial tests indicated turbid water conditions, particularly at depths of 155 feet and 205 feet, where high concentrations of silt and iron were detected. The testing involved a series of pump tests, including a step test that increased the pumping rate to 800 gallons per minute, which resulted in notable drawdowns in nearby wells—up to seven feet in some cases. This drawdown suggests a hydraulic connection between Well Twelve and the surrounding aquifer system.

To mitigate the water quality issues, officials proposed the installation of an iron filter at the facility and recommended limiting the well's pumping capacity to 600 gallons per minute to minimize impacts on local water levels. Further investigations indicated that isolating the upper and middle aquifer zones could improve water quality. A packer was used to seal off these zones, allowing testing of the lower aquifer at depths of 345 feet, which showed promising results with minimal iron contamination and no adverse effects on nearby wells.

The meeting concluded with a recommendation to install a liner in Well Twelve to enhance its structural integrity and further develop the well to remove residual silt. This approach aims to increase the well's capacity to between 1,000 and 1,200 gallons per minute while ensuring minimal disruption to the regional aquifer system. The officials emphasized the importance of ongoing monitoring and testing to ensure the safety and quality of the water supply for the community.
