In Moldova, there was a general decrease in nitrate concentrations in rivers, barring a peak in 1998. The general decrease can be related to a decrease in agricultural activities. Data were available for three lakes/reservoirs in Moldova. Total phosphorus concentration showed a steady decrease in the two reservoirs (Dubăsari Centrala Hidroelectrică and Costești Centrala Hidroelectrică) between 1992-2017. However, for Lake Ghidighici in the Chișinău area there was a marked increase between 2005-2012, with a subsequent decrease back to original levels. The increase might be related to a larger input of untreated urban waste water and higher fertilisation rates in agricultural activities.
