Radioactive deposits in California - USGS

Reconnaissance examination by Government geologists of many areas, mine properties, and prospects in California during the period between 1948 and 1953 has confirmed the presence of radioactive materials in place at more than 40 localities. Abnormal radioactivity at these localities is due to concentrations of primary and secondary uranium minerals, to radon gas, radium (?),

I averaged the pH levels for each elevation and put that information on a chart. The data revealed that the high-elevation streams in my study reflected lower pH levels. The mean pH level for streams above 2,000 feet was 6.6.
