Safe Drinking Water Program

The Safe Drinking Water Program provides comprehensive drinking water protection to the citizens and visitors of Louisiana supervising over 1,300 public water systems for compliance with state and federal drinking water regulations.  The Safe Drinking Water Program objective is to prevent illness and death that can occur from waterborne disease outbreaks or chemical exposure associated with contaminated drinking water. The Safe Drinking Water Program accomplishes this objective by the activities listed below. 

  • Monitoring: Collection, analysis and review of bacteriological and chemical samples to ensure compliance with maximum contaminant levels, treatment technique requirements, monitoring and analytical requirements.
  • Inspections: Sanitary surveys and site inspections are conducted to evaluate the capability of a drinking water system to consistently and reliably deliver an adequate quality and quantity of safe drinking water to the consumer and to ensure compliance with state and federal drinking water regulations.
  • Engineering Plan Review: Conducts reviews of and issues permits for new construction and modification of public water systems including the source, treatment, storage and distribution facilities to ensure the quality and protection of drinking water.
