<br />3.5 OTHER CONSTITUENTS <br />The major constituents other than the carbonates are <br />presented on pages B-72 through~B-87. The heavy metals with a "t" <br />subscript by their symbol are total measurements, while the others <br />are dissolved concentrations. Dissolved and total concentrations <br />are similar for most of the heavy metals, except for iron <br />concentrations where the total values are generally significantly <br />greater. <br />Only one radium concentration during 1990 exceeded the <br />drinking water standard of 5 pCi/1. The other three values from <br />this well averaged less than one pCi/1. Significant radium <br />concentrations have naturally existed in the ground water in the <br />• vicinity of Trapper Mine. The elevated concentrations exist in the <br />area of mining as well as the area to the east. <br />u <br />3-14 <br />
