NOTES:
Turbidity has no health effects. However, turbidity can interfere with disinfection and provide a medium
for microbial growth. Turbidity may
indicate the presence of disease-causing organisms. These organisms include bacteria, viruses, and
parasites that can cause symptoms such as
nausea, cramps, diarrhea, and associated headaches.
