God grundvattenkvalitet?

Sammanfattning: Clean drinking water is a crucial part of a healthy society. During the last decades, a lot of emissions from different sources have put the drinking water sources that are used today at risk of pollution. This study aims to investigate the groundwater chemistry and contamination situation in the aquifer of Bergaåsen in the municipality of Ljungby in Sweden. This is done through analysis of chemistry data recorded between the years of 1993 and 2018. It is done together with an investigation of contaminated areas within the recharge area of the aquifer. The study shows that there are high levels of iron, manganese, PFAS and pesticides in the groundwater. Furthermore, the alkalinity as well as the pH are low in the water. The investigation of contaminated areas shows that there are seven contaminated areas within the catchment area of the groundwater source. These contaminated areas might be the source of the high levels of iron, manganese, cupper, PFAS and pesticides, but they might have contaminated the groundwater with substances, that are not analysed for, as well. The study therefore concludes that the groundwater in the aquifer of Bergaåsen is contaminated with unhealthy levels of iron, manganese, pesticides, PFAS, pH and alkalinity, but more analyses must be done to determine how the groundwater can be cleaned to get healthy drinking water.
