PFAS Contamination Discovered in Maui Business Park Water System: What You Need to Know

PFAS, also known as perfluoroalkyl and polyfluoroalkyl substances, have been found in water samples from the Wai’ele wells 1 and 2 chlorinator at the Maui Business Park water system in Kahului, Maui. This water system serves about 64 businesses in the area and is classified as non-transient and non-community. The detection of PFAS was reported in a lab report from February 20, 2024, and confirmed in a report from March 27, 2024. The businesses served by this water system have been notified of the detection.

The water system informed the Department of Health (DOH) about the presence of PFAS through an email on April 3, 2024. The levels of PFAS detected are below the Maximum Contaminant Level (MCL) set by the Environmental Protection Agency (EPA) for PFOA. However, there are no established MCLs and Hazard Index for other types of PFAS detected in the water system, such as PFHpA, PFHxA, PFPeA, and PFBA.

This issue is currently being addressed to ensure the safety of the water supply in the affected area. The DOH has taken steps to investigate further into this matter to determine if additional actions need to be taken to protect public health. Local institutions have been made aware of this concern and are working closely with them to ensure that everyone who may be affected is informed.

The map above shows the area where PFAS was detected, impacting the businesses in that location. It’s important for those businesses to take precautions while using tap water until it’s clear that it’s safe again. This is a reminder that sometimes unexpected contaminants can enter our drinking water supply and it’s crucial to be vigilant about protecting ourselves from potential harm.

In conclusion, while some levels of PFAS were found in these water samples, they were below regulatory limits set by EPA for some contaminants like PFOA. However, more research needs to be done regarding other types of PFAS present in these samples before any decisions can be made on whether or not they pose a significant risk to public health. It’s important for everyone involved with this situation to stay informed so we can work together to protect our community’s well-being.
