WATER QUALITY DATA ARCHIVE

2002
Water quality results posted here are from the KBAC funded project to understand Kawai Nui marsh and problems associated with marsh restoration. Water samples were collected from two perennial streams -- Maunawili and Kahaniki just before they enter the marsh, and from the marsh itself.

Sampling stations are arranged on this page from upstream to downstream. Note that the "Links" column provides lab information and a link to additional data for each station.
