"Two streams in the Heath Steele Mines area of New Brunswick were determined to be affected by metal pollution (Zn and Cu). These streams and the springs of the area are not polluted in their natural environment because the sulphide ore in its natural unbroken state was unoxidized and, therefore, insoluble. The pH of these natural waters ranged from 6.0 to 8.0 while the value of total dissolved solids was low as indicated by specific conductance values of less than 100 micromhos/cm. Therefore, the metal pollution in the Northwest Miramichi must be caused by the Heath Steele mining operation at the head of the Tomogonops River basin"--Abstract. gccst Water pollution gccst Mining industry gccst Water quality Canada.
