The results and interpretations reported here are reconnaissance in nature, designed to identify and rank the major problems on the CWS, and are given with the caveat that further detailed studies by more precise methods will be required to confirm and quantify chemical conditions Time_Period_of_Content: Time_Period_Information: Range_of_Dates/Times: Beginning_Date: 199706 Ending_Date: 199909 Currentness_Reference: Ground condition.
