road salt
- applied to roads in winter
- washes off roads into lakes and streams
- seeps into groundwater and private wells
- affects freshwater organisms
combined sewer overflows
cyanobacteria
- starves marine organisms of oxygen
- makes animals sick -- including us!
farm runoff
- bad for us, bad for otters
hydraulic fracturing
water quality monitoring
- Sample collection, lab analysis: labor intensive + costly
- Sensors that record data, long-term: ~$1000 (~$10000)
- Typical sensors: proprietary hardware + data

publiclab: open-water
--> building an open source water quality sensor!
- to be deployed in rivers, streams, private wells ...
- collect sensor weeks / months later
- needs to be: low-power, low cost, accessible
- provides ongoing baseline --> detect anomalies
- temp + conductivity + depth (+ turbidity? + ?)
- fully open source
- Mystic River Open Water pilot project
- crowdfunding: Public Lab + IOBY
remote + independent + friendly field logger electronics
- electronics: the mchck + custom shields
- conductivity circuit inspired by practicalMaker
- enclosure: PVC pipe + optional 3D printed end-cap
- power: lasts months on 3 AAA's
- entirely open source
- < $100
applications
- measure: temp, conductivity, depth (+ optical?)
- deploy for weeks + upload data to repository
- look for correlations / anomalies in data
show + tell
- electronics
- enclosure
- user interface
- temp, conductivity measurements
- depth, optical measurements
online data viz
- Mary Martin's prototype
- Jeff Walker's prototype
- Amherst College open water hackathons
civic engagement
- Catherine's babbling brook project
- the thermal-flashlight project
- STE(A)M curricula
- grassroots workshops
- MyRWA + Amherst Media + AMS + NH crew + ...
next steps
- depth, optical measurements
- calibration and testing
- increased accessibility
- distribution plan
- telemetry
- STEM / STEAM; workshop planning
- other applications?
