An Arizona creek threatened by pollution from a proposed copper mine near Phoenix will receive lead and copper contamination limits under a proposed consent decree that the Environmental Protection Agency announced Thursday.

The proposal, called the lead and copper rule improvements, would for the first time require utilities to replace lead pipes even if their lead levels aren't too high. Most cities have not been forced to replace their lead pipes and many don't even know where they are. Some cities with ...

For example, it is the level of lead or copper which, if exceeded in over 10% of the homes tested, triggers treatment for corrosion control. Cancer Classification: A descriptive weight-of-evidence judgment as to the likelihood that an agent is a human carcinogen and the conditions under ...
