Nowadays, the waste ponds of the Inowrocław Chemical Plants “Soda-Mątwy” SA are not used for regular disposal of
pollutant materials. Despite this, the salinity level of groundwater and soils in the neighbourhood of these ponds is still very high.
The main reasons of this are the huge amount of waste stored for decades and very unfavourable location of this factory in the river
valley. In the salty area there are saline meadows with halophytes such as: Salicornia europaea, Glaux maritima, Triglochin maritima,
Aster tripolium, Puccinellia distans, Atriplex hastata var. salina and Spergularia salina.
