The results are in involving samples taken at Charlotte Beach.

Last week, News10NBC told you about students from Rochester's "Freedom School" who collected water samples.

Monday, the students announced they've figured out some answers to their question: Why is Ontario Beach closed to swimming on some days and not others?

The students say a lot of it had to do with bacteria in the water. They say one way people in the area can help is by picking up garbage on the beach.

"If the beach is not clean, we're not going to be able to swim in there and we don't have a lot beaches in Rochester, so our advice would be keep it clean, for the environment and the community," student Shane Noble says.

The group is part of the "Get Real! Science Action Camp."

The program pairs teens with graduate students from Rochester's Warner School of Education.

Rochester may have a reputation for being a cold and snowy place, but the popularity of beach volleyball has spiked. In the past ten years, Rochester has become a hot-bed for volleyball, both indoor and beach.

Rochester produces higher caliber high school players who have received Division I scholarships than any other area of the state. Interest in the indoor game is now moving to the beach.

McQuaid graduate Steve O’Dell is usually playing in a gym, but his summer nights are spent at Charlotte Beach.

O’Dell said, “I like the beach because I can touch it every time. I like the indoor game that’s fun as well. I think they bother contribute to being a great volleyball player overall.”

O’Dell is headed to UCLA on a full ride for indoor volleyball. He bucked a family trend after his three older brothers went to Penn State.

One of the best parts of living in Rochester is the easy access to Lake Ontario, but health concerns have limited the public's access to the beaches. Now officials in Irondequoit are trying to get area residents to help keep Durand Beach clean.

The Monroe County Health Department sent out more than 10,000 mailers to people who live in the Durand watershed to inform them that water from their property can end up at the beach. Officials say that storm water runoff and septic systems overflows in northern Irondequoit end up in small streams. Those streams empty into ponds that run along Lake Ontario.
