Aloha and welcome to the West Oahu Air Quality Monitoring website.

Hawaiian Electric Company operates a network of three ambient air quality monitoring stations located on the Waianae Coast.  The monitoring stations were placed into operation in April 2009 as part of a commitment made by Hawaiian Electric to the west Oahu communities.  The monitoring stations are one of six commitments made in conjunction with the development of a new power generating station at Campbell Industrial Park.  More information about these commitments, also referred to as community benefits or givebacks, can be found by clicking here.

Current real-time data for several air quality parameters that are measured at the stations are shown below in terms of the Air Quality Index.  The data are updated hourly at about 15 minutes after the hour.  More detailed information can be found on this web page by clicking the underlined text.
