2. AGENDA Social Data Science Why water, why now? Who’s got the data?
Intros, Housekeeping, etc
Why water, why now?
Who’s got the data?
Who’s an expert?
What can we do?
Open Discussion

3. 71% Water Only 1.7% is fresh water
Our planet is 71% water of that only 1.7% is freshwater
Only 1.7% is fresh water

4. Why now: World #1 risk according to World Economic Forum
Climate Change
World population growth
Agriculture
Water pollution
1.8 billion people in areas with scarcity problems by 2025
2/3 of world population in water stressed regions by 2025
VA tech researches did in home testing and found water to be toxic

6. Why now: California No Winter Snow = No Resupply
Underground water is stop-gap
Does not replenish quickly
More people than ever
1970 > 20million
2016 nearly 40million
VA tech researches did in home testing and found water to be toxic

8. Why now: Flint, Mi Switched water supply
19x more corrosive than previous
Ate into iron & lead pipes
Researches found water to be toxic
$100/day could have avoided issue
VA tech researches did in home testing and found water to be toxic

10. WHY NOW: Minnesota Adrian, MN North Shore
Farm chemicals polluted wells
1 of 8 communities now treating for nitrates
North Shore
High levels of mercury in water
1 in 10 babies born with unhealthy levels

11. WHY NOW: Minnesota Threats facing lakes
Excess nutrients = algae blooms
Road water runoff (salt & chloride)
Construction sediment
Invasive Species (Zebra muzzels)

12. WHY NOW: Minnesota Threats facing rivers & streams
Similar pollutant issues as lakes
Erosion
Course alteration
Invasive Species (Asian Carp)
Impacts those living outside of MN

13. WHY NOW: Minnesota Threats facing wetlands Benefits watershed health
Similar pollutant issues as lakes
Draining & Filling
Benefits watershed health
50% of historical wetlands gone in MN

14. WHY NOW: Minnesota Threats facing groundwater
Land use practices
Industrial contamination
Overuse
Road salt
Source of 75% of drinking water in MN
Used for nearly all crop irrigation

25. Starter Ideas Fiscal Data Time Series Analysis Impact of weather
Haves & have-nots of quality water
Time Series Analysis
Which areas are getting better/worse?
Impact of weather
Where & when does weather cause issues?
