What type of intake is usually located near a lake or river to capture seepage from sediment?

• A. Surface water intake
• B. Infiltration gallery
• C. Stream channel intake
• D. Subsurface withdrawal structure

Answer: (B)

The type of intake that is typically located near a lake or river to capture seepage from sediment is the infiltration gallery. This system is designed to enhance the collection of groundwater from surrounding areas, allowing water to naturally filter through the sediment before it is captured for treatment and distribution. Infiltration galleries are constructed so that they lie beneath the surface, often buried under several feet of soil or sediments. This positioning takes advantage of the natural filtration process as water seeps through layers of soil and rock, thereby removing particulates and improving water quality. The design not only allows for the collection of high-quality water but also minimizes the chances of contamination from surface runoff. The other types of intakes serve different purposes. Surface water intakes are typically used to extract water directly from the surface of lakes or rivers without the benefit of the natural filtration provided by sediments. Stream channel intakes focus on capturing water directly from the flow of a stream, which may not involve seepage at all. Subsurface withdrawal structures refer to systems designed for deeper aquifers and do not specifically capture seepage from sediment in a surface water context. This distinction solidifies the infiltration gallery as the correct choice for the described scenario.
