[SOLVED]Chemistry – Copper limits in water

Hi, I’m trying to help my girlfriend find articles where the main topic is:
– allowable limit of copper in the river – allowable limit of copper in the sea – allowable limit of copper in the soil
– allowable limit of copper in subsurface water
But so far I’ve had no luck. I’ve tried Google, ACS and EPA.
All that remains is Bing
Any help will be greatly appreciated.
