Krull Park Beach in Olcott was closed to swimming Thursday because of high levels of E. coli bacteria found in Lake Ontario water samples taken Wednesday morning.
Ronald Gwozdek, principal public health engineer for the Niagara County Health Department, said the lake's waters were churned up by thunderstorms Tuesday and Wednesday. He said he believes that action caused the rise in bacteria readings at the surface. Four other water quality testing points along the lake that are independent of beaches also failed their tests Wednesday, he said.
More samples were taken Thursday. The results will be available Saturday morning, but the beach is closed at least until then, Gwozdek said.
This is the second beach closure of the season at Krull Park. The first was July 18-20.
