What thickness is required for the welded steel cap on temporarily abandoned wells?

The required thickness for the welded steel cap on temporarily abandoned wells is specified as 3/16 inch. This thickness is sufficient to ensure the integrity and durability of the well cap, providing a robust barrier against contaminants and environmental factors that could potentially enter the well. A cap of this thickness strikes a balance between strength and manageability, ensuring that it can be securely welded to prevent any unauthorized access or accidental infiltration into the well.

Using this specific thickness helps mitigate risks associated with well abandonment, ensuring that any remaining water or potential contaminants are adequately contained. It also complies with industry regulations that aim to protect water resources and public health. The choice of 3/16 inch is in line with best practices in well construction and maintenance, reflecting a standard that has been established based on experience and regulatory guidelines.
