Hi Change Community, I was wondering if anyone on this list knew about how or where (e.g. a lab) to submit a Seattle Public Utilities-provided tap water sample for contamination testing, or if anyone here has relevant equipment and knowledge/expertise on water contaminants (could be even just a microscope to examine for microbes/algae). My research lab is working with the Nickelsville Northlake housing group, which has reported severe water quality issues and managed to capture a sample of brown water coming out of their faucets (this happens once every few months). We would like some way to find out what it is and if it's dangerous. Do you know of any public resources for this? Alternatively, has anyone here used the City of Seattle water quality hotline <https://www.seattle.gov/utilities/your-services/water/water-quality/quality-concerns> before? Finally, are there folks on this list who have experience with or would recommend a DIY test kit like the following, or something else? https://www.homedepot.com/p/LABTECH-H2O-OK-Plus-Complete-Water-Analysis-Test... https://www.amazon.com/Health-Metric-Coliform-Bacteria-Test/dp/B07VBBCS6J Thanks so much, -Esther 1280 AFA4 DD14 589B <https://keybase.io/infrared>
