Question 1
Q 1(a) Threats to freshwater resources

 Pollution
 Destruction of freshwater eco-systems
 Impact of climate change
 A resurgence of water related diseases
Q 1(b) Defining Good Surface Water Status
As per Water Framework Directive, “A good surface Water Status means that there
are no concentrations of various priority substances which exceed the relevant EQS which are
established in Environmental Quality Standards Directive 2008 (O’Boyle and et.al., 2019). It
aims to protect the sensitive species from direct toxicity as well as including the predators
and humans through secondary poisoning”.
Q 1(c) Significance of water body
The Water Framework Directive needs every member for protecting and improving
the water quality in all waters so that it can attain the good ecological status. It is committed
towards attainment of appropriate quantitative and qualitative status of all the water bodies
such as ocean as well as including marine water (Stefanidis and et.al., 2019).
Q 1(d) Thermal stratification in lakes
