Sample question:

Which of the following is a disease you can get from drinking water?

B) Meningitis
C) West Nile virus

Answer: Giardiasis is caused by the protozoan Giardia lamblia. Most infections in the United States occur in the warmer months during late spring, summer and early fall. This is believed to be due to people swimming in untreated waters and accidently swallowing the contaminated water.
