Tryptophan-like fluorescence as a measure of microbial contamination risk in groundwater
Tryptophan-like fluorescence (TLF) data is paired with faecal indicator bacteria (Escherichia coli and thermotolerant coliforms) concentration data. The TLF results that have been corrected for probe sensitivity (using calibration equations based on standard solutions of L-tryptophan at 30 degrees Celsius). The TLF data are paired with E. coli data from compartmental bag tests and m-ColiBlue24 filtration plate counts and with thermotolerant coliform data from laurel sulphate filtration plate counts. Temperature, pH, electrical conductivity and turbidity data are also included. Duplicate and replicate samples are indicated.
