Under LT2, which three parameters were added for testing?

• A. Cryptosporidium and Giardia
• B. Giardia, E. coli, and turbidity
• C. Cryptosporidium, E. coli, and turbidity
• D. Cryptosporidium, Giardia, and E. coli

Answer: (C)

LT2 focuses on strengthening monitoring for the protozoan Cryptosporidium, using E. coli as a fecal contamination indicator, and turbidity as a practical measure of how well the treatment and filtration processes are performing. Cryptosporidium is a key pathogen of concern in surface water because it resists disinfection and can slip through if treatment isn’t effective. E. coli provides a straightforward microbiological signal of recent fecal contamination, helping assess water quality. Turbidity reflects the amount of suspended particles; higher turbidity can hinder disinfection and indicate filtration loading, so tracking it helps ensure the treatment train is maintaining adequate removal and disinfection performance. That’s why the three added testing parameters are Cryptosporidium, E. coli, and turbidity. The other options mix in Giardia or omit turbidity, which isn’t part of this LT2 testing set.
