Data Trends in Water Quality and Percent Live Coral Cover
Hui O Ka Wai Ola data through Dec.2020 showing a comparison of geomeans for turbidity (water clarity) and nitrates/nitrites relative to the Hawaii Department of Health state standards. That is, the values on the y-axis show the number of times a parameter exceeds the state standards. For example, Kahana Village located near the mouth of Kahana Stream has an average turbidity ~43 times the standard.
