In what ways does groundwater geology contribute to toxicity risks?
Groundwater geology is critical in evaluating toxicity risks. The movement and quality of groundwater are influenced by the geological formations it flows through. Aquifers composed of limestone can neutralize acidic contaminants, whereas those in volcanic regions might dissolve toxic elements from surrounding rocks. The presence of fractures in rock formations can also facilitate the rapid spread of contaminants, increasing the risk of exposure to toxic substances.
