Additional Information

All radiochemical drinking water samples are analyzed for gross alpha (4002), gross beta (4100), radium 228 (4030) and uranium mass. If the combined gross alpha and radium 228 radioactivity exceeds 5 pCi/L, then radium 226 is also analyzed.

If gross beta radioactivity exceeds 50 pCi/L, then the Beta radiochemicals group is scheduled for collection and analysis.
