Goal: To help water systems in New England find analogous systems that may be used as a case study in their evaluation of optimum corrosion control for compliance with the LCRR.
   
Note: Survey results shall be used for informational purposes only and should not be regarded as professional engineering advice or used for regulatory compliance. Changes in water quality and treatment should always be reviewed and approved by the applicable State regulatory agency and licensed water quality/treatment professional.
