KEY TO ABBREVIATIONS:

 

MCL = Maximum Contaminant Limit

SMCL = Secondary Maximum Contaminant Limit

BDL = Below Detection Limit

mg/L = milligrams per Liter or parts per million

µg/L = micrograms per Liter or parts per billion

< = Less Than

> = Greater Than

(a) = Sample(s) taken from the distribution system.

(b) If Gross Alpha is less than 5 pCi/L, no further radiological testing is required other than radon testing.
