Employees were using a Hydrovac to find an underground line.  The Hydrovac has a nozzle to shoot high pressure water and suck up water and mud.  One employee works the vacuum hose and another works the water nozzle. The employee working the vacuum hose saw a rock that he didn't think would go up the vacuum hose. When he reached down to pick it up, he stepped in front of the water nozzle.  The pressurized water punctured his knee on the inside of his right leg.
