Time to flip your computer over and check your answers!

1. A – Taking a five minute shower uses 10-25 gallons of water, while a full tub requires about 70 gallons. If you take a bath, stopper the drain immediately and adjust the temperature as you fill the tub.

2. C – A leaky toilet can waste about 200 gallons of water every day! To tell if your toilet is leaking, place a drop of food coloring in the tank; if the color shows in the bowl without flushing, you have a leak.

3. C – The average bathroom faucet flows at a rate of two gallons per minute; by simply turning the tap off, you can save more than 100 gallons of water per person each month

4. B – If your toilet is from 1992 or earlier, you probably have an inefficient model that uses between 3.5 to 7 gallons per flush. New high-efficiency models use less than 1.3 gallons per flush; that’s 60% - 80% less water than their less efficient counterparts.

5. C – Even though 75% of the earth’s surface is covered by water, less than 1% is available for human use. The rest is salt water, locked in inaccessible locations underground or is frozen in polar ice caps and glaciers.
