Basement wall leak at water supply entry

Recent heavy rains in the midwest have brought about a leak at the point where the copper water supply line enters through my basement wall. The leak is not from the pipe - it only began recently and only occurs when we have a heavy rain. I've removed one panel of the finish wall and see that the leak has been at the water pipe entry.

Is there a good way to solve this leaking problem? What type of sealer can I use to do so? What method may be necessary to stop the leak for good? Will some sealers that may be used cause any reaction with the copper pipe to cause it to be eaten away and have a more serious problem?

Thanks for any suggestions.

It would be nice if you could caulk it on both sides.
Use silicone - once dry it is non-toxic and non-corrosive.

Cool

You also can use black plastic roofing cement, which can even seal in the rain when the surfaces are wet.
Wear old clothes, throw-away rubber gloves, etc. This roofing cement is VERY sticky. I usually get more on me than the job, but it seals great! LOL
Good Luck!
