Physical method of confinement by which barriers are constructed to prevent or reduce the quantity of liquid flowing into the environment. Consists of constructing a barrier across a waterway to stop/control the product flow and pick up liquid or solid contaminants What is Underflow Damming ... Spill control tactic used to trap floating lighter than water materials behind the dam. Dam is constructed in a manner that allows uncontaminated water to flow unobstructed under the dam while keeping the contaminant behind the dam. What is Overflow Damming... Spill control tactic used to trap sinking heavier than water materials behind the dam. With the product trapped, uncontaminated water is allowed to flow unobstructed over the top of the dam.
