Radionuclides are natural occuring (usually) substances, that are of concern, and are checked on a routine basis by the State. Again, we tested at both our treatment plants, 260 E. Washington St. is EP#1, and our plant on McKinley Avenue is EP#2.

Sample Date
Gross Alpha
Gross Beta
EP#1
3/23/1998
1.6+1.4 pCi/l = 3.0 pCi/l
0 +/- 2.6 pCi/l
EP#2
3/23/1998
0+1.2 pCi/l
0 +/- 2.6 pCi/l
Maximum Contaminant Level
15 pCi/l
4 pCi/l
Quoting from the letter we received from IDEM concerning these tests - "Since your system has not exceeded the action limits of 5 pCi/l for gross alpha particle activity and 50 pCi/l for gross beta particle activity, your system has fulfilled the necessary monitoring requirements for the radionuclides for this compliance period."
