William noticed that his household's water bill was higher than usual. Wastewater is any water that has been used for basic household activities and enters a sewage system. Wastewater travels from a sewage system to a treatment facility, where it is filtered and discharged. Lawmakers place limits on how much wastewater can be discharged into bodies of water in order to maintain safe water quality levels.

What is one way William can reduce wastewater buildup?

• Wash fewer clothes per cycle.

• Regularly check toilets for leaks.

• Take longer showers and shorter baths.

• Use the dishwasher for small loads of dishes.

• The global oil reserves will continue to decrease.

• The global oil reserves will continue to increase.

• The global oil reserves will remain relatively steady.

• The global oil reserves will turn into alternative forms of fuel.
