What is defined as the 'Seasonal High Groundwater Level'?

The definition of 'Seasonal High Groundwater Level' refers specifically to the shallowest depth to the water table during typical annual conditions, which corresponds to periods when groundwater levels peak due to seasonal factors such as rainfall and snowmelt. This level is significant because it can affect various environmental considerations, including the placement of heating oil tanks, as it indicates how high groundwater might rise during certain times of the year.

Understanding this concept is essential for professionals working with heating oil tanks, as the proximity of groundwater to the tank can impact the risk of contamination or affect the structural integrity of the tank systems. Groundwater levels can fluctuate based on weather patterns and seasonal changes, making it crucial to know the high point each year to manage and mitigate potential risks effectively.
