Which of the following is a water delivery-related cost that water utilities are asking or requiring their customers to bear?
  1. Construction of new treatment plants to remove pollutants
  2. Drilling new wells to replace contaminated ones
  3. Replacing lead and cast-iron pipes to stop leaching
  4. All of the above
Explanation
Answer: D - All of these substantial costs are necessary to upgrade water systems for health and safety reasons. The extent to which they are necessary varies geographically. Both urban and rural water districts are concerned about the cost implications for low-income and low-population customer bases given that the bulk of these new delivery costs are fixed, and must be spread among all customers.
