BP just announced that oil has stopped leaking from it’s well into the Gulf of Mexico on day 86 of the environmental disaster.

Officials have been testing a cap to temporarily halt the leak. It was put in place Monday with its valves left open. Government officials were afraid the build up of pressure from closing the valves could cause additional leaks. After further analysis BP engineers were given the okay to close the valves. Wednesday night a leak was detected  before testing of the new cap could begin. As of Thursday morning, the minor leak was repaired. As of Thursday afternoon, the gushing major leak has been plugged.

Work on a permanent fix, relief wells that will plug the spill from below with mud and cement, will resume. The relief well’s timeframe has always been hazy, with company and federal officials giving estimates ranging from the end of July to the middle of August before it can be completed.
