The technician immediately conduct an investigation, to determine the presence of copper metal pollution that is known to react with blond hair. But in the early observations, the technicians found the levels of copper in water resources within normal limits.
The investigation continues into a house with a hot water storage. Sure enough, when the hot water accommodated overnight then increasing copper content up to 50-10 times higher than current flowed from the water company.
Believed, copper pollution comes from the pipes is peeling due to heat water passed. Worst conditions in the sense of having the highest copper content was found in new homes, which generally use low-quality pipes.
"Water samples we have taken from older homes have copper levels are relatively lower," said one of the environmental health technician, Johan Pettersson told the newspaper quoted from Dailytelegraph Skanskan, Wednesday (28/12/2011).
