Update on Chlorine Residual Sampling
Dear young "sciengineers",
The sampling today went well in both groups. We are collecting all the data from y'all and will distribute them soon!
I attach the monochloramine calibration curve for you to calculate the monochloramine residual.
I will have to remember to bring bigger gloves next time, putting them on was challenging for some of you.
The plates are being incubated @ room temperature and will be ready for you to do the colony counts on Tuesday.
Thanks for your collaboration. I hope you learned something new today, and of course, that you enjoyed the sampling and measurements.
JP.
Pict: Green colored compound indophenol is proportional to the concentration of monochloramine in the sample. From left to right, basement to 10th floor, skipping 2nd floor (under construction).
