Which reports must a public water system furnish before placing a new well into service?

The requirement for a public water system to furnish a driller's log and a well casing cementing certificate before placing a new well into service reflects essential safety and compliance standards. The driller's log provides crucial information about the well's construction and geological formations encountered during drilling. This log contains data such as the depth of the well, the types of materials encountered, and the water levels, which are vital for assessing both the efficiency and safety of the well.

In conjunction with the driller's log, the well casing cementing certificate ensures that the well is properly sealed to prevent contamination from surface sources. This is important for protecting the quality of the groundwater being extracted and, ultimately, for safeguarding public health. Ensuring that the casing is properly cemented restricts the movement of water between different aquifers and minimizes the risk of pollutants entering the groundwater supply.

By requiring both of these documents, the regulatory framework seeks to ensure that new wells are constructed in a way that meets public health and safety standards. This is why the combination of a driller's log and well casing cementing certificate among others is necessary before a new well can be operational.
