What must be included in the information recorded on the well log report form after pump testing?

The inclusion of the static water level in the well log report form after pump testing is essential because it provides critical information about the groundwater depth within the well. The static water level indicates how high the water naturally sits in the well before any pumping occurs. This measurement is vital for understanding the well’s hydrology and the available water supply, which can influence both the design of the well system and its long-term sustainability.

By accurately recording the static water level, contractors and landowners can gauge the impact of the pumping process on the aquifer, assess the well's performance, and make informed decisions about water usage and management. This information can also be valuable for future well maintenance, troubleshooting, and regulatory compliance.

In contrast, while the type of drill used, the location of the well, and the cost of drilling may be relevant for different aspects of well development and documentation, they do not directly affect the immediate understanding of the well's operational characteristics following pump testing as much as the static water level does.
