3 bacteria monitoring requirement
- Results to fdep by the 10th of following month
- All pws systems do raw sample for each well
- # of samples based on population
(2) Bacteria failures means
Repeat samples from site of failure, within 5 connections upstream and 5 service connections downstream within 24 hrs of being notified of results
The mcl of coliform bacteria is based upon the presence or absence of the bacteria
According to chapter 62-560-410 fac, public notice must be made for violating of the mcl contaminants that post an ACUTE risk to humans
ASAP but no later than 24 hrs after learning of violation
