What we are testingWe look for sediments, nutrients, and other pollutants from land-based sources that might be having a negative impact on water quality. We collect data for ocean salinity, pH, temperature, total nitrogen, nitrate-nitrite nitrogen, ammonium, total phosphorus, phosphate, silicates, dissolved oxygen (DO) and turbidity. Some water samples are immediately tested at mobile labs, while others are processed for testing at University of Hawaiʻi [and/or other] labs.
As funding and our volunteer community grows, we will expand our efforts into other water quality research, such as source detection and working with partners to delve deeper into some of the pollution “hot spots” our data has helped identify. We also hope to expand monitoring to other areas. |

Is the stream flowing?
The graph below shows the current stream flow for Honokohau, Maui
(measured from the nearest functioning stream gauge in west Maui).
Big spikes in the graph mean more water flow in Honokohau, which
can also mean possible stream flow in Wahikuli and transport of
pollutants into coastal waters from these areas.
