| Resumo: | A study is presented on the pH, redox potential (Eh), dissolved oxygen (DO), and temperature (T) in the Paso Bonito reservoir, used as a source of drinking water supply for the Cienfuegos City. This reservoir has its basin located mainly in a mountain area, affected by the organic, physical, and residue pollution from an old pyrite mine. From September 2006 through November 2007 samples were collected at meter intervals from the surface to bottom near water withdrawal site. The reservoir was polymictic during wet summers, and monomictic during dry summers. During thermal stratification it had a clinograde oxygen distribution pattern, a pH between 7.0 and 8.1 and a negative hypolimnetic Eh during thermal stratification. We derived an empiric model relating Eh, DO and T. The correlations between the studied indicators were also determined. These results will facilitate the interpretation of highly complex phenomena such as the release of nutrients, metals, and organic matter from the sediments. |
