Toxic heavy metals in ground water of a portion of the Front Range mineral belt
MetadataShow full item record
A study of toxic trace metal distribution in ground waters of the Front Range mineral belt, Colorado and adjacent areas was completed in order to determine the relationship of water quality to mineralization and the magnitude of potential health effects. A total of 149 samples were collected and analyzed for arsenic, cadmium, copper, iron, lead, manganese, mercury, silver, and zinc. Field determinations of pH, Eh, and specific conductance were also made. The trace element data exhibited a lognormal distribution and are described utilizing the geometric mean and geometric deviation. Four populations ...
