Water Quality 10% open

Czech Republic

What data is expected?

Data, measured at the water source, on the quality of water is essential for both the delivery of services and the prevention of diseases. In order to satisfy the minimum requirements for this category, data should be available on level of the following chemicals by water source and be updated at least weekly:

  • fecal coliform
  • arsenic
  • fluoride levels
  • nitrates
  • TDS (Total dissolved solids)

What data is available

  •   Openly licensed? No (No URL given)
  •   Is the data available for free? Unsure
  •   Is the data machine readable? No (n/a)
  •   Available in bulk? No
  •   Is the data provided on a timely and up to date basis? No
  •   Publicly available? No(as Systém monitorování zdravotního stavu obyvatelstva ČR ve vztahu k životnímu prostředí published by The National Institute of Public Health (NIPH))
  •   Is data in digital form? Yes
  •   Is the data available online? No (No URL given)
  •   Does the data exist? Yes


The National Institute of Public Health publishes a report every year, it's a quite thorough one, but in pdf only. However, there is no information about TDS (all the other chemicals are monitored), therefore I'm marking this dataset as non-existing

Reviewer comments

They do collect water quality data, while there is no TDS, they are following standards this is acceptable. However, data is not available in a timely manner and only in an aggregated report format.
