1. Chitosan biopolymer as an adsorbent for drinking water treatment : Investigation on Arsenic and Uranium
Sammanfattning : In many countries over the world (including Sweden), metal toxicity in freshwater resources causes a severe drinking water quality problem and poses a threat to the environment and human health. Among the different toxic metals in the water resources of Sweden, arsenic and uranium are the biggest threats to health. LÄS MER
2. The influence of multiscale hyporheic flow on solute transport : Implications for stream restoration enhancing nitrogen removal
Sammanfattning : Stream water that flows into and out of streambeds is called hyporheic exchange flow (HEF).It continuously interacts with groundwater and thereby affect the water quality of local streamreaches as well as downstream recipients by providing an environment where solutes andenergy can be retained and degraded.

3. Lake Hydrodynamics and Pollution Transport under Climate Change : The Case of Lake Victoria
Sammanfattning : A very small part of the total earth’s water is freshwater (only 2.5 %). Unfortunately, due to climate change and pervasive manmade activities, surface freshwater quality in many places of the world has become degraded. LÄS MER
4. Water in roads: Flow paths and pollutant spread
Sammanfattning : For better road construction and maintenance while minimising damage to the environment and groundwater, it is essential to monitor and model hydrological impacts on roads and consider pollution of groundwater. Water content in unbound material in road layers changes continuously and water flow usually occurs along pathways that are the main corridors for pollutant spread to groundwater. LÄS MER
5. Groundwater resources in hard rock coastal terrains : Insights into heterogeneity and spatial variability
Sammanfattning : Challenges regarding water security in hard rock coastal regions with limited soil cover are: a seasonal absence of recharge during times of peak residency, heterogeneity and variability of the fracture network, close proximity to saline water sources and spatially inconsistent storage and extraction. In areas where it is not feasible to connect residents to municipal water systems, a better understanding of the resilience of reservoirs is needed. LÄS MER
