The image above shows algae in tubes being tested at the university of Minnesota, they are used at waste water plants and the algae can be:
"
- Cultivated and harvested as a source of energy
- Used to remove carbon dioxide, phosphorus and nitrogen from waste water
- Used as a carbon offset to meet anticipated greenhouse gas emission requirements
With this brief i have considered the situation of a household wanting to measure the environmental impact of their waste water. I am hoping to use a visual comparison method or colour scale by grass or algae. I am planning to make the measuring product practical and applicable in a household capacity, eg as an item of furniture. (see above)
Who: home owners, small businesses
Why: personal environmental concern, government regulation, novelty
Where: houses, small businesses, public spaces (acid rain)?
What: effects of household chemicals and processes on wastewater and therefore environment

that looks really green (in the environmentally friendly way) and interesting! you can also look into the thermal pollution caused by hot water, though that's usually more of a concern for nuclear power plants...
