Egypt, Sand Hills and Peggotty beaches in Scituate have reopened for swimming after being closed on Thursday by high bacteria counts. <\/p>\n
Follow-up testing done Thursday on water samples showed almost no contamination atEgypt and Sand Hills. The bacteria level at Peggotty Beach was elevated but within acceptable limits, and the water was not retested. <\/p>\n
The other 62 salt-water beaches on the South Shore are open. <\/p>\n

HOW BEACHES ARE TESTED <\/p>\n
Sixy-five beaches on the South Shore are tested for intestinal bacteria found in humans and animals. <\/p>\n
High levels indicate the possible presence of disease-causing microbes that are present in sewage but are more difficult to detect. Bacterial colonies are filtered from three ounces of water and placed on a gel infused with nutrients and chemicals designed to promote growth. <\/p>\n
Left in an incubator, the single cells isolated on the filter grow explosively, forming colonies visible to the naked eye. After one day, the colonies are counted and if they exceed 104 colonies, the beach is closed to swimming. <\/p>\n
If the past five samples have a mean exceeding 35 colonies, the beach must also be closed to swimming. <\/p>\n
