Last week, the Environmental Daily Advisor discussed the renewable fuel standard (RFS), equipment leaks, and private drinking wells.

Here's the Environmental Daily Advisor week in review.

House Hearing on RFS--At a June 5, 2013, hearing of the House Subcommittee on Energy Policy, Health Care and Entitlements, EPA and several witnesses discussed issues with RFS.
