ERIE, Pa. (AP) — Officials at Presque Isle State Park have issued the first swimming advisories of the season after elevated levels of E. coli bacteria were found in the water.

Monday's advisories affected the water off of five of the parks' beaches.

Swimming isn't banned during the advisories, and beaches remain open. But swimmers who have weakened immune systems or open cuts and sores are advised to stay out of the water.

Water at the park's beaches is tested for the bacteria twice a week. The advisories will be lifted when new tests show the bacteria levels have dropped to safe levels.

E. coli is found in human and animal feces and generally serves as a marker that shiga toxin and other harmful substances are present. The shiga toxin can cause gastrointestinal problems.

Students do not receive official diplomas at the graduation ceremony, instead they are mailed to students a few weeks later.Pitt spokesman John Fedele (FEE'-del) says the diplomas will arrive about 10 days later. University officials are double-checking the spellings of student names so new diplomas can be rush-ordered and in the mail by July 2.Pitt officials aren't saying how much the new diplomas will cost.
