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!
