The rivers Vuoksi, Hiitolanjoki, Rakkolanjoki, Urpalanjoki and Lake Nuijamaa (the Saimaa canal) . Southeast Finland Centre for Economic Development, Transport and the Environment (KAS-ely) and the Russian party (Neva - Ladoga Water Authority) take samples from the same rivers in their own side of the border between the countries, on the same days . Additionally Finland is monitoring water quality in the rivers Jänisjoki, Tohmajoki and Kiteenjoki, and from Russia to Finland falling Koitajoki. Measured variables . Measured parameters correspond to the ECE Transboundary Water Agreement Monitoring recommendations . Monthly measured: secchi depth, temperature, O2, oxygen saturation, pH, conductivity, suspended solids, turbidity, color, CODMn, BOD7, Tot-N, Tot-P, Fe, Mn, and Na .
