Summary

Arno River water quality analysis revealed that while drinking water met standards, river water required treatment. Effluent samples had acceptable chemical levels but exceeded bacteriological limits, with enteric viruses detected in some samples.

Area of Science:

  • Environmental Science
  • Microbiology
  • Public Health

Context:

  • Analysis of water quality in the Arno River and its associated urban effluent.
  • Assessment of compliance with Italian water quality regulations (Executive Order n. 152/99, Presidents Decree n. 236/1988, Executive Order n. 31/2001).

Purpose:

  • To evaluate the chemical and microbiological safety of Arno River water for drinking purposes.
  • To assess the quality of urban wastewater effluent discharged into the river.
  • To detect the presence of enteric viruses in water samples.

Summary:

  • River water samples (n=22) classified as A3, necessitating treatment for potable use. Drinkable water samples met regulatory standards.
  • Effluent samples (n=11) showed compliance with chemical parameters but exceeded bacteriological standards due to insufficient chlorination.

  • Enteric viruses, including Coxsackievirus B2 and Poliovirus, were detected in 5 samples via RT-PCR, with no correlation to bacteriophage indicators.

    • Impact:

    • Highlights potential public health risks associated with inadequately treated river water and effluent discharge.
    • Underscores the need for improved chlorination in wastewater treatment to meet bacteriological standards.
    • Suggests that bacteriophages may not be reliable indicators for enteric virus contamination in this context.
