Hui O Ka Wai Ola, a citizen science, coastal water quality monitoring program has undergone another expansion to include 12 more testing sites in South Maui, bringing the total number of testing sites across Maui to 48.

The program first launched in 2016 in West Maui and underwent an expansion in November to include a dozen test sites in South Maui.

The program is made possible under a joint effort from the Maui Nui Marine Resource Council, The Nature Conservancy, the West Maui Ridge to Reef Initiative and University of Hawaiʻi.

Hui O Ka Wai Ola is the first community-based water quality monitoring program on Maui to measure for nutrients (including nitrogen and phosphorus) in coastal waters.

Organization backers say nutrients can be indicators of sewage pollution and agricultural, golf course and landscaping runoff. Once in the ocean, these nutrients can lead to algal blooms. Algae, particularly invasive species, can quickly out-compete coral reefs for sunlight and overrun large tracts of living reef. Program leaders say sediment coming from construction and agricultural lands can also be detrimental.
