Erin Brockovich tells hundreds of upset North Texans to fight for better drinking water

FRISCO -- Environmental activist Erin Brockovich, who weeks ago set off alarm among thousands of North Texans by questioning on social media the safety and quality of water in Plano and surrounding communities, spoke here Thursday night before more than 500 people clamoring for more information.

And announcing a new discovery, she questioned whether the North Texas Municipal Water District could be trusted after the state had just cited the utility this week for failing to perform some tests for volatile organic compounds last year.
