Drinking Water Regulation

The process of regulatory development is a lengthy one, with even the most basic drinking water rules requiring years to move from the initial stages to final promulgation. AMWA provides a strong, constant voice for member utilities throughout the process. At each step of the regulatory development process, from initial contaminant identification and scientific research to final promulgation, implementation and subsequent reviews, AMWA stays engaged with staff at the Environmental Protection Agency (EPA) and other federal agencies to ensure the final results improve public health within a structure that makes sense for drinking water utilities.

EPA’s drinking water regulatory agenda includes work on several items of great interest for AMWA members, and AMWA staff will maintain a strong voice in the discussions:

  • Regulatory development for revisions to the Lead and Copper Rule based on National Drinking Water Advisory Council (NDWAC) workgroup recommendations.
  • Regulatory determinations from the third Contaminant Candidate List (CCL3)
  • Clean Water Rule
  • Stakeholder consultations on carcinogenic volatile organic compounds
  • Fourth contaminant candidate list (CCL4)
  • Fourth Unregulated Contaminant Monitoring Rule (UCMR4)
  • Evaluation of harmful algal blooms (HABs) and associated algal toxins
  • Revisions to Risk Management Plan requirements

Other ongoing efforts, such as modeling the effects of low-level perchlorate exposure using a physiologically-based pharmacokinetic (PBPK) model to set a maximum contaminant level goal (MCLG), evaluations of incoming UCMR3 results and ongoing six-year review processes also continue.

AMWA’s vigilance on these and any new regulatory initiatives is continuous, providing assurance that member utilities always have a strong voice with regulators in Washington, D.C.
