WEF Discussion Forums : Laboratory Management and Technical Issues : Guidance for TNTC on Q-Tray E.Coli and HT  

Please advise - what does your wastewater lab do when bacterial numbers are too numerous too count (TNTC) using an enzyme substrate method, given the current 40 CFR regs state that wastewater samples must be analyzed within six hours?  

 

Thanks!
