Box-Whisker DiagramsWhat Can We Use Them For?
A B C D
A – A “Good” System. Box and whiskers are short and compact.
B – A “Bad” System. Results are all over the place. Box and whiskers are stretched out.
C – A “Consistently Bad” System. Compact but well above TN limit (19 mg/l)
D – A “Usually Pretty Good” System. Compact but maybe a couple of high results.

Keeping Track of it All…“Cleaned Up” Sample Exceedance Report
• Exceedance reports will be delivered quarterly.
• BOH will decide what action to take, since each BOH will likely have a different policy.
