Eleanor Roosevelt: if substitute to petrol was to be found, it will be, because it was done in past, 1948
South Bronx poorest district
World’s largest food distribution centre
Less trees, parks that most places in the country
Lungs are linked to brain: proximity to fossil fuel emission source and poor intelligence
We do things not bec these are easy, but because these are difficult
We should not use the term waste water, we cant waste people any more, it is a process which is not productive
Peter gleick: pacific instt
Solving water problems solves education, health and food problems,
Post apartheid program: working for water, removing alien vegetation from watershed, restored ecosystems, gave work, restored flows, hugely successful program;
We cant forget that technology has unintended consequences: poor water quality; clean ground water, millions of bore water to reach cleaner ground water because surface water was bad, that lead to arsenic problem;
Water weirdos: some solutions violate physics laws and some violate social and or institutional laws
We need to rethink choices we had rejected in past
Mark Tonkin:
Dutyion membrane; absorbs water, plants can be grown from sea water without desalination, put salt water inside these pipes and only vapor of pure water comes out;
70 per cent of all fresh water goes to irrigate crops
What are the limits of the technology:
Sea water was 35k ppm salt
Water being used was 25kppm
Settlement tank:
No power, only gravity==========================trenching between trees—making plant work for water;
Demand for salt: heat is stored in molten salt:
Water testing:
Mark sobsey
Film: inoculate the sample, culture the bacteria: grow the bact in bottle, let it grow, colour change, no quantification, but presence is told;
Absorbent pads for water testing:
Chromegenic agents for testing fecal bacteria;
No water testing facility in ketrina in usa and also in Haiti
Ashok gadgil:
Shallow handpumps: arsenic pollution
140 million people are exposed to arsenic pollution
Arsenic binds to iron electrodes;
Andrew tinka:
Sensors for water quality: rivers, install sensors at a place in river and then monitor the water quality
Innovation is to have floating water sensor
Gps laoded sensor records watr quality along with gps value
Traffic map for water
2 parts per thousand of salt, this is ok for rice
Young salmon tok wrong turn, went toward
Delta
Why was salmon gong down the wrong direction?
Sensor with fish behaviour may be floated and then one coul see why the fish take wrong direction
Emergency response systems floating sensors
One drop: liliana peresa
Nicaragua, ivania: did not have access to safe water
Technical, education and micro credit: tripod approach
Family garden
Drip, roof top water harvest
Floating sensor: Andrew tinka
Seeds from different catchments may enter the water stream and then grow in the cana bed and damage it, floating sensor will tell us where
Vectors movement along water
Nitrate flow form farms to canal
High cost sensor that moves,
New type of business model for monitoring the effluents
Ideal conditions for fish breeding

Non point becomes the point pollution

Turbine at the bottom
Dispenser of chemicals, dyes, to measure the dynamic nature of river, or its properties, various reactions could be measured through release of the small substances
Aquifer by aquifer value of water quality yin deep bores
Air column at different heights and width
