The Commonwealth Utilities Corp. was able to resolve the e-coli problem in its drinking water system last Saturday and advised that that there is no longer any need to boil the water before use.
CUC notified water system customers Friday about a problem with the drinking water and advised its customers to boil their water before use in the affected area of the Isley Tank Service.
The affected areas were Koblerville, Chalan Piao, Afetnas, Chalan Kanoa, Susupe, San Antonio, and Oleai (San Jose).
In a press release last Satrurday, CUC executive director Gary P. Camacho said the chlorination equipment has been repaired and water operators continue to ensure that the water distributed has adequate amounts of chlorine, which meets the drinking water requirements of the Bureau of Environment and Coastal Quality and U.S. Environmental Protection Agency.
Camacho said the samples collected last Friday were absent of total coliform and E. coli bacteria.
Last Thursday, CUC found E. coli bacteria in the water supply, prompting the utilities agency to issue a warning to customers in the affected areas.
E. coli bacteria can make people sick especially those have weakened immune systems.
CUC said bacterial contamination can occur when increased run-off enters the drinking water source, such as heavy rains. CUC said it can also happen due to a break in the waterpipes or a failure in the water treatment process.
Last Friday, CUC announced that they found out that an equipment failure caused the amount of chlorine to be too low to treat the water in the Isley Reservoir.
Camacho said that water operators repaired the problem last Thursday, to provide adequate amount of chlorine.
Camacho said the Isley Reservoir had adequate amounts of chlorine in the system last Friday.
