Keiki Water Fest

The Keiki Water Fest will be held Saturday at Hawaii's Plantation Village, 10 a.m. to 2 p.m. Admission is free.

The Water Fest will feature displays, demonstrations and hands-on activities that include interactive stations about stream sampling, water conservation, porosity and permeability, wetlands, "Apoha" picture-taking, drinking water, invasive species, limu, aquatic species, Effective Microorganisms, HAZMAT and modern firefighting.

Plantation Village docents will be on hand to answer questions. And Jeff Gere of the City Department of Parks and Recreation will hold a story-telling session, 11 a.m.

The Keiki Water Fest aims to help students — targeting fourth- and fifth-graders — and their teachers and families recognize the importance of clean water in their daily lives. The festival also will provide opportunity to learn about water's role as an animal habitat, common water pollutants and how to protect and conserve water.

Pouhala Marsh and Kapakahi Stream cleanup effort

The city and the state Department of Land and Natural Resources will provide tents, supplies, equipment, field support, T-shirts and portable lavatories for the Saturday cleanup at Kapakahi Stream and Pouhala Marsh.

Twenty volunteers, age 16 and older, are needed to plant native trees and to remove trash, sorting combustible and recyclable material.

Volunteers will receive trash bags, gloves, T-shirts, refreshments, educational material and give aways. Volunteers should have a hat and sunscreen and dress to get dirty.
