Anne Arundel County health officials warned Monday against swimming, water skiing or any other contact with water at Glen Isle in Riva because the water there could make people sick. Water samples taken last Tuesday and Thursday at the South River beach contained high bacteria levels, which officials said could be caused by a variety of factors, including rainfall, tidal action and wildlife. Anyone who does touch water there should wash with soap and warm water immediately, officials say, and also wash any clothing that got wet or splashed. The beach, tested twice weekly during the summer, will remain closed until bacteria counts return to safe levels for at least two consecutive days.
