Tests by the West Cost Regional Water Supply Authority have found the water supplied to central Pasco County is not contaminated, eliminating the need to boil it before drinking.
The authority had advised Pasco County Utilities customers in and near Land O'Lakes and Odessa to boil water after a main supplying Pasco and Pinellas counties ruptured.
The advisory, covering Lake Padgett, Wyndham Lakes, Parker Point, Fairway Springs and Ellington Place subdivisions, went into effect Thursday afternoon.
Saturday, utility workers completed bacteria testing on the central Pasco supply line and found the water was safe to drink, West Coast said.
The 84-inch main ruptured Thursday near Gunn Highway and State Road 54, causing pressure to drop on a line supplying the Odessa and Land O'Lakes areas, West Coast spokeswoman Michelle Klase.
The drop in pressure made it more likely that those customers would receive tainted water, she said.
The ruptured main carried 50-million to 60-million gallons of water a day to Pinellas and western Pasco counties.
West Coast said it expected to have the main restored and working by Monday or Tuesday.
