A salutatorian is a graduate who finished with the second highest rank in his or her class. Only the valedictorian did better. Being the salutatorian of your graduating class is a great honor. Traditionally, the salutatorian gives the opening remarks at the graduation ceremony. So, just as a salutation is a greeting, a salutatorian is responsible for offering a formal greeting at the event. Having been a salutatorian looks great on a resume, as long as you spell it correctly.

All the levels of soil and sand above it provide decent filtering. Recently though run off from sewage systems and other sources such as MTBE have been found to penetrate these systems.
