STORY SUMMARY

KAʻŪ, Hawaiʻi - The Hawaiʻi County Department of Water Supply says the normal use of tap water in the affected area may resume immediately.

(BIVN) – The Precautionary Boil Water Notice for customers of the Waiʻōhinu – Nā‘ālehu Water System has been cancelled, effective immediately.

The Hawaiʻi County Department of Water Supply issued a notice on Friday, explaining that additional bacteriological testing of the Waiʻōhinu – Nā‘ālehu Water System was conducted. “Laboratory water analysis confirms that coliform bacteria and other potential microbiological contaminants are not present in the water system and that the water meets all regulatory drinking water quality requirements,” the department said.

The DWS says:

  • Normal use of your tap water may resume immediately.
  • It is no longer necessary to boil tap water or use bottled water for drinking, cooking, making
    ice, or brushing teeth.
  • Recommended post-notice step: Flush building, residential taps, hose bibbs, water fountains,
    and ice makers for several minutes based on the extent of your plumbing before first use.
  • For water quality questions, call DWS’ Water Quality Assurance and Control Branch at 808-
    961-8670.

The water department noted that the cancellation of the Precautionary Boil Water Notice applies only to water quality requirements. The repair and recovery of infrastructure damaged by Hurricane Lala is ongoing.
