Which geologic property decreases significantly after cave roof collapse?

💡 Explanation

Groundwater pollutants lose natural attenuation due to reduced residence time because the collapse creates a direct conduit to the unconfined aquifer, increasing flow velocity; therefore, water has less contact with the filtering rock matrix, rather than promoting recharge directly.
