The City of Pella Water Treatment Plant has been certified with the State of Iowa to test for Fluoride and Coliform Bacteria. If you would like to have your water tested, the Water Treatment Plant is happy to assist you. If you would like a bacteria sample, a sample bottle must be picked up from the Water Treatment Plant to collect the sample and you will need to follow sampling directions (PDF). All other samples can be taken in any container and need to be brought to the Plant within 24 hours of the sampling. This service is available to anyone wishing to have their water tested.
