• Current Drinking Water Standards
Directs EPA to develop:
1. National Primary Drinking Water Standards using Maximum Concentration Limits (MCL)
1. First establish MCL(G) goals
2. Set MCL as close to goal as possible using BATs - 80 total
2. Underground Injection Regulations
3. Groundwater protection Grant Programs
6. Sewage treatment
