Question

when constructing roadways or buildings adjacent to groundwater sources, what should engineers consider to ensure that aquifers have adequate recharge areas? diverting alternative water sources directly into sewers to reduce flooding maintaining porous surfaces and protecting possible contamination zones paving over natural recharge zones to prevent contamination increase depth of groundwater sources to store more water

Explanation:

Porous surfaces allow water to infiltrate and recharge aquifers. Protecting contamination zones ensures that the recharging water is clean. Diverting water to sewers reduces recharge. Paving over recharge zones blocks infiltration. Increasing groundwater depth doesn't directly relate to recharge areas.

Answer:

maintaining porous surfaces and protecting possible contamination zones
