Simultaneous Compliance Website
This Simultaneous Compliance Tool assists in making appropriate choices to comply with various water quality goals emanating from water quality regulations. The SCTool utilizes a framework of technology-based rules to identify potential unintended consequences based on user defined treatment and source water quality parameters. Users can define anticipated future system conditions to eliminate or minimize potential negative unintended consequences. This exercise will educate the user to make more informed decisions about treatment changes for compliance purposes minimizing negative consequences of their decisions. Additional system-specific testing and demonstration may be needed once a short list of suitable technologies is identified using the SCTool.
    Technologies covered in the Small System version of the tool include:
  • New Chlorine Application Info
  • Optimization of Chlorination Practices Info
  • Chemical Sequestration Info

DISCLAIMER:
The simultaneous compliance conflicts and unintended consequences suggested by this SCTool represent the opinions of the Research Team based upon current available literature and empirical experience. The SCTool output and suggestions are intended to inform utility decision-making -- but should not be used in place of system-specific data collection and economic analysis. In most cases a complete assessment of selected treatment technology will require the assistance of a licensed design professional. In some cases pilot plant or full-sale treatability data will need to be collected in accordance with state primacy agency requirements.
The output and suggestions generated by the SCTool do not necessarily reflect official positions of the US Environmental Protection Agency, or the Water Research Foundation.
