aging water infrastructure the environmental protection agency (epa) researchers and engineers work to help communities deal with aging and failing drinking and wastewater systems. on the morning of december 23, 2008, drivers in suburban maryland were confronted with a torrent of water rushing down river road. somewhere beneath the pavement, a sixty - six - inch water main ruptured, allowing some 150,000 gallons per minute to cascade onto the road in standing waves three to four feet high. rescue crews launched from boat, fire engine, and helicopter were able to rescue all stranded motorists and their passengers. luckily no one was hurt. following a four - month forensic investigation, the washington suburban sanitary commission determined the cause of the water main break could be traced back to its original installation in 1965. at forty - three years of age, the pipe lurking beneath river road was relatively young compared to many still in use in areas of the country that are easily twice that age, or older. the nations water infrastructure—the pipes, treatment plants, and other critical components that deliver drinking water and remove and treat wastewater—is aging. which quote provides relevant evidence for the authors claim that the water infrastructure is aging? a. “as many as 75,000 yearly sanitary sewer overflows discharge three to ten billion gallons of untreated wastewater, leading to some 5,500 illnesses.” b. “every year across the country, there are approximately 240,000 water main breaks.” c. “rescue crews launched from boat, fire engine, and helicopter were able to rescue all stranded motorists and their passengers.” d. “at forty - three years of age, the pipe lurking beneath river road was relatively young compared to many still in use in areas of the country that are easily twice that age, or older.”

Answer

Brief Explanations:

The claim is about aging water - infrastructure. Option A focuses on sewer overflows and their consequences, not directly on aging. Option B mentions water - main breaks but doesn't relate to aging. Option C is about rescue operations, not related to aging infrastructure. Option D directly refers to the age of pipes and compares it to other older pipes in use, providing evidence for the aging of water infrastructure.

Answer:

D. "At forty - three years of age, the pipe lurking beneath River Road was relatively young compared to many still in use in areas of the country that are easily twice that age, or older."
