Much of the credit for revitalizing the LA River goes to a grass roots group Friends of the LA River (FOLAR).
But there is no protocol to warn people about the bacteria levels in the water, and that can be a big concern for the increasing amount of people who do activities along the river.
Marissa Christiansen, FOLAR's executive director, joined Take Two about who she thinks should be in charge of a water quality alert system and what it would look like.
