Test of well cap under way

A test is under way on a new, tighter cap over the leaking well in the Gulf of Mexico. The government gave the go-ahead for the test after a daylong delay prompted by concerns that the cap might make the leak worse. The oil has been leaking into the Gulf of Mexico since the Deepwater Horizon exploded April 20, killing 11 workers. (Sources: Multiple, 07/14/10)
