Erin_BrockovichErin Brockovich was arrested Friday night on suspicion of boating while intoxicated at Lake Mead near Las Vegas.

The environmental activist, whose battle against Pacific Gas & Electric was portrayed by Julia Roberts in the 2000 film Erin Brockovich, reportedly had a BAC just over twice the legal limit of .08 percent. She had been out on the water with a male companion.

Brockovich has since issued an apology, in which she states that she did not operate the boat in open waters and did not post a public safety risk.

 That being said, I take drunk driving very seriously, this was clearly a big mistake, I know better and I am very sorry. After a day in the sun and with nothing to eat it appears that a couple of drinks had a greater impact than I had realized.

She was released from  the Clark County Detention Center after posting $1,000 bail.

Laws in PA state that  boating under the influence is similar to a DUI offense. If a person operating a boat has a BAC of .10 percent or greater, they are considered to be under the influence. However, a BAC between .05 and .10 can still result in evidenc ein determining whether a person was or was not under the influence.
