Which of the following is NOT one of the basic types of cleanups for heating oil tanks?

Groundwater remediation is an essential practice in managing environmental contamination but is not classified as a basic type of cleanup specifically for heating oil tanks. Instead, it deals with the purification of groundwater when it has been contaminated by pollutants, which can include substances other than heating oil.

The basic types of cleanups focus more on the immediate surrounding environment and methods used to remediate soil and manage risks associated with contamination in situ. For instance, a soil matrix cleanup targets the soil directly impacted by a spill, while generic remedy approaches are standard practices applied to common issues encountered in heating oil tank leaks. Risk-based decision-making cleanups involve evaluating the level of risk posed by contamination and determining the appropriate cleanup strategy based on those risks.

Thus, while groundwater remediation is an important aspect of environmental management, its focus is broader and not specific to heating oil tanks, making it the correct choice for identifying what is not considered one of the basic types of cleanups in this context.
