How does groundwater flow affect UST site assessments?

Understanding groundwater flow is crucial for determining the extent of contamination and potential risks to drinking water sources. Groundwater flow impacts the migration of contaminants that may leak from underground storage tanks (USTs). If there is a spill or leak, knowing the direction and velocity of groundwater flow helps assess how far and in what direction the contaminants could travel. This information is vital for identifying affected areas and ensuring that remediation efforts are targeted effectively. Additionally, identifying the proximity of contamination to potential drinking water sources is essential for protecting public health, as contaminants in the groundwater can pose significant risks if they reach these sources. Hence, thorough assessments of groundwater flow are integral to effective site assessments and risk management strategies in the context of USTs.
