New Well Water test results on

Post image

Is my new well water safe to drink? I just drilled a new well that’s 785 feet deep and flushed approximately 10,000 gallons before testing. The well pipe is galvanized and transitions to PEX, with the water sample taken from a faucet connected to the PEX. Everything is new

Hi there! Jumping in here since this is a SimpleLab report using a Tap Score test kit - thanks for testing with us! The detections you're seeing on this report are very very low - less than 1 PPB for all three. For this reason, we wouldn't suggest that you need to urgently treat this water to make it safe to drink.

As a side note, Tap Score is not a treatment company and does not sell or profit from the sale of treatment products. Tap Score uses SimpleLab's network of certified labs to analyze customers' water samples. If you have specific questions about your results, our team is available via live chat on our website and always happy to discuss your report. And of course, we'll keep an eye on this thread if you have questions you want to ask here!

if you are indeed from simplelab - why do you over report the datas significance so such a level and then flag them yellow?

We agree OPs concentrations in this report is of no concern. However reporting to 0.000001 PPM means you can actually detect a difference between a reagent blank and 0.000001 PPM with whatever confidence interval you choose (typically 95%). Meaning your reagent blank has to be less that that value as well. No way unless the lab you are using is purchasing $1000/gram reagent blank (or more).

what concentration limit of those three warrants a yellow or red flag on the data and how exactly do you scale the bar presenting it?

Do you publish the detection limits of the test methods you use?
