Notes:     (1) Station Location: Springville Dam (Site 1459-042)
      (2) Data sources: International Joint Commission (1983), International Joint Commission (1987 b ), New York State Department of Health (Mr. William Condon, personal communication Apr. 12, 1996)
      (3) Symbols: (--) not measured or not reported; (<) less than lower limit of detection of instrumentation in use (LLD) or offscale in some manner; (ND): not detected.
      (4) U.S. EPA Drinking Water standards: If gross exceeds 50 pCi/L, then analysis for specific radionuclides must be performed. The allowable upper limit of gross radiation is 50 pCi/L. The allowable upper limit for gross radiation is 15 pCi/L of which the combined activities of the radionuclides 226 Ra and 228 Ra cannot exceed 5 pCi/L.
