The Upper Tisa Valley. Preparatory proposal for Ramsay

In most samples nickel was present in low concentrations, but the peak at the
Tiszabecs station attained the limit of the acceptable category.
In terms of the peak zinc concentrations the water was classified „polluted” at
the border station, but improved to „acceptable” farther downstream. In terms of
aluminium the water was highly polluted, but the concentration diminished in the
direction of flow and the quality improved to acceptable at Balsa. The concentration of
heavy metals was found depend decisively on the quality of flow past the border
station.
The peak pH levels indicated slightly alkaline water but remained below the
limit of „good” water quality. Electric conductivity, as a measure of total dissolved
substances, has met the criteria of excellent good water quality.
