Volunteers are needed to collect water samples at Kualoa Beach Park on Feb. 6, as part of Water Quality Snapshot Day.

The activity will take place from 9 to 11 a.m., beginning at the first restroom upon entering the park.

Water Quality Snapshot Day, sponsored by Hui o Ko'olaupoko, allows citizens to gain firsthand experience in assessing the health of their local watershed.

Kits will be provided and participants will learn ways to improve water quality.
