Welcome to the H2O Q data collection website!

Engage with water chemistry, and contribute to the community of data.

  • Community Science Data is for anyone that has the tools to measure pH, conductivity (TDS), phosphate, nitrate, dissolved oxygen, temperature, and/or turbidity. This data is for the educational purpose of practicing science, learning about water quality parameters, and engaging communities in our most precious natural resource.
  • Quality assured methods or processes are recommended, but not necessary to contribute data. User beware!

Quality Assured Water Quality Data

H2O Q understands the need and process for quality assured data and has incorporated this layer to the map to facilitate data sharing. The expectation for this map layer is that water quality-assured sampling and analyzing protocols have been used. Please contact H2OQ@cmich.edu for the data entry link to add your water quality data.
