In a Triassic sandstone woodland (Schlitzerland in Hesse, Western Germany) 17 springs were hydrologically and hydrochemically investigated throughout one year (April 1973 - April 1974). Measurements were carried out on water volume, temperature, electrolytical conductivity, pH, aikalinity, chlorinity, dissolved molecular oxygen, dissolved organic material (COD), ammonia, nitrite, nitrate, and free phosphate. Among the hydrochemical factors investigated the pH-value was closely related especially to the micro-climate in the spring drainage area. In particular the pH rose both with increasing length of the drainage area and — within the same spring with decreasing water supply. On the other hand the pH-value diminished with increasing altitude of the drainage area. Simultaneously the highest values were found on SW-slopes and the lowest ones in NE-exposures.
