It’s been a minute, but we finally have results from our latest batch of samples. Please follow this LINK to see color-coded printouts of all our sample results from Kula, and please follow this LINK to see results from Lahaina. Each printout lists the street where the sample was taken and the sampling date. We continue to work on improving the way we share data on this site, but for now we want to make all of our sample results available for viewing, even if it’s not the most user friendly way. The results from these 14 samples look very similar to the results from previous batches.
Results Summary: We have only found a single location that showed signs of fire related contamination, and this was at a house in Kula that sustained fire damage and was already disconnected from the water system. Otherwise, the VOCs we are seeing are primarily related to chlorine disinfection. These compounds are called disinfection byproducts, and the specific ones we are seeing are within a group called trihalomethanes (THMs). Please see this FAQ for more information on THMs.
Overall, what we have seen so far is good news, and while we and the county still do not have enough data to confidently say that the system is free from contamination, each clean sample we find is a step in the right direction.
It should be noted that the levels of THM’s we are seeing in some samples are higher then health guidelines proposed by the MN Department of Health. (Link) However, we have not found levels of THMs higher than the regulatory limits set by the HI Department of Health and US EPA (link)
