The ground water from well 6 (site 1) yielded both the most depleted S13C and most enriched 834S. Isotopic compositions of this dual nature are consistent with methanogenesis and bacterial sulfate reduction, arising form interaction with organic-rich (bog) soils from below.

For peat bogs and tropical forests this balance is not observed. The soil in tropical forests emits C02 at a rate almost twice as high as the rate of C02 input to the soil from dead plant matter. 

The success of these comparisons is due to the particular type of water of this specific syncline of the folded Jura where the highly-acid running water, drained from bogs, changes to hard water when it passes through the underlying limestone. The importance of the soil for the chemical composition of the groundwater is underlined. 

The existing data for the reduction of N-nitrosoamines in anaerobic sediments and soils suggests that the aromatic substrates will be much more reactive. For example, N-nitrosodiethylamine and N-nitrosodisopropylamine were found to be very persistent in sediment slurries. In contrast, the reduction of N-nitroso-diphenylamine was quite fast (t,/2 = 1-5 days), resulting in the formation of diphenylamine (Weber, 1988). Formation of the intermediate, 1,1-diphenylhydrazine, was not observed. Several N-nitrosodialkylamines also have been found to be very persistent in flooded soils and microbial enrichments from bog sediments (Tate and Alexander, 1975).

As with other factors, no direct statements can be made relating the reaction of a soil to its corrosive properties. Extremely acid soils (pH 4 0 and lower) can cause rapid corrosion of bare metals of most types. This degree of acidity is not common, being limited to certain-bog soils and soils made acid by large accumulations of acidic plant materials such as needles in a coniferous forest. Most soils range from pH5 0 to pH8 0, and corrosion rates are apt to depend on many other environmental factors rather than soil reaction per se. The 45-year study of underground corrosion conducted by the United States Bureau of Standards included study of the effect of soils of varying pH on different metals, and extensive data were reported. 

In many northern regions, peat bogs are widespread. Our study shows that peat groundwater can have geochemical responses consistent with its interaction with kimberlite rocks (Sader et al. 2007). The geochemical responses can be different from those in mineral soil. Therefore, exploration in peat bog terrains requires specific sampling methods. 

At the opposite end of the fertility scale from ricefields are peat bogs in pluvial landscapes. Nutrient inputs come almost entirely from rainfall, and the nutrient reserves in the organic matter buffering the soil solution are small (Moore and Bellamy, 1974). The chemistry of peat bogs is therefore precarious and changes in the composition of the rainfall can have a large effect on the composition of the soil solution.
