In table 9, on p. 25, correct the gross beta (human-health benchmark (HHB)) of 50 pCi/L to indicate that it is a screening level rather than and MCL. Show the screening level as a cross-reference to new footnote 6. Add a new footnote 6 to read as follows: "USEPA screening level; values shown do not exclude naturally occurring radionuclides (DeSimone, 2009, p. 41). If exceeded, after correction for naturally occurring radionuclides, the USEPA recommends that specific radionuclides be identified through further testing."

In the Radionuclides section, on p. 53, change "the MCL of 50 pCi/L" to "the screening level of 50 pCi/L".  

In the Summary and Conclusions section, on p. 73, change "had gross beta-particle activities equal to or greater than the MCL" to "had gross beta-particle activities equal to or greater than the USEPA screening level of 50 picocuries per liter (pCi/L)" and change "2,060 picocuries per liter (pCi/L)" to "2,060 pCi/L" in the next paragraph.
