This report is a continuation of the work on a helium survey presented in Open-File Report 80-181, which covered the period Sept., 1977 - June 30, 1979. Water samples were analyzed for helium collected from twelve springs and wells, of which four are new locations. A brief description of these stations is given in Table 1 and their location is shown on the map of Figure 1. Two springs (303 and 304) previously reported on do not appear in this report. Station 306 was discontinued after August 11.
