The water from Matre River is characterized as very soft,
with a total hardness of 1. 5 - 2. 5 mg Ca0/1 and a very low
buffer capacity. Acid precipitation results in low pH, values
below 5. 0 are recorded every year. As a consequence of the
water quality, several systems for pH adjustment has been
tried, most of them having evident limitations. In this paper
several of them has been described and evaluated. A special
attention has been put on the two systems which at the moment
are beeing used at the station and which we think are holding
promise. These are the neutralizing systems based on the
addition of sodium hydroxide and well pumped salt water.
