Water Quality Investgation
potential methods/ what to test for
pH testing
chloride test
temperature testing
salinity test
dissolved oxygen test
turbidity test
nitrate + phosphate
pesticides
redox
electrical conductivity
water hardness
what is the water management in Australia like?
how are civilians affected? (drinking, irrigation)
how are water levels measured?
how regularly are water levels checked
what are the guidelines?
who regulates them (e.g. SA Water)
social + environmental implications
third world countries + access to clean water. limited resources to check water quality
human influence on waterways: depositing large particles of pollution
how does the presence/lack of heavy metals affect humans and other living organisms
lead
mercury
cadmium
vanadium
where is the drinking water sourced? how sustainable is it?
what is water used for?
for recreational uses
for consumption: potable vs. non-potable
irrigation for plants/crops
general cleaning
at home
commerically
manufacturing
what affects water quality?
the presence of ions in the water (conductivity, water hardness)
fluoride in drinking water as it has heath benefits
how are ions filtered and removed? separate by charge? some particles have a stronger charge than other
hard water may be good for health but very hard may cause build up problems and soap scum)
presence of dirt + other solids
makes sample non-homogenous
affects turbidity
not good for potable water
salinity
high salinity usually bad
impacts agriculture + aquatic wildlife + other organisms
