For the last 33 years, Daniel Chang has been involved in environmental education and outreach, in one form or another, while working on drinking water and groundwater quality with the Hawaii Department of Health. Chang has been instrumental in getting groundwater education tools into the hands of educators. He understands the value of groundwater as a natural resource and its finite nature.
“If we contaminate or waste this resource, we cannot go out and get more, so we need to be good stewards, use it wisely, and protect it from contamination,” he said. “Education and outreach is one way to get the message out. Knowledgeable citizens and students are important in ensuring good quality water now and into the future.”
Although it’s surrounded by water as an island state, Hawaii relies on groundwater as its main source of water for drinking and irrigation. Over 500 million gallons per day of groundwater is used in the state to fulfill domestic, commercial, and industrial needs. Groundwater provides about 99 percent of Hawaii’s domestic water and about 50 percent of freshwater used in Hawaii. Hawaii’s groundwater resources may appear plentiful, but much of the precipitation runs off to the ocean in streams or returns to the atmosphere by evapotranspiration.
Naturally, Chang wanted to help Hawaiians understand this resource. “Working in the State’s Groundwater Protection Program, we would get calls from schools to talk about groundwater in Hawaii and needed a way to explain how groundwater works to students,” he said.
While looking for possible activities that he and his colleagues could use to present to students, he came across the AAK and JUG through the Groundwater Foundation catalog, and was excited
about how the tools could be used.
“The interesting part of these kits was that they were simple, yet provided several activities that we could do to teach the students about groundwater,” Chang explained. He said they use both the AAK and the JUG to teach students groundwater basics.
The kits have been used in a variety of educational settings that showcase their adaptability. From groundwater displays at Earth Day events and county fairs, Project WET educator trainings, special events like the annual Make-A-Splash Water Festival conducted by the Kauai Department of Water, to direct education in classrooms with students, the JUG and AAK are helping to spread the message about groundwater.
They’re making an impact. “Students enjoy the different activities that we teach them using these educational tools,” Chang said. “Many of them ask us when we are coming back to do more activities with them.”
Other agencies have also embraced the kits as teaching tools, including Chang’s Hawaii Department of Health and the Kauai Department of Water, which Chang said has has spurred environmental education beyond groundwater. He points out that in the recently completed Hawaii State Science and
Engineering Fair, personnel from the Department of Health judged 20 projects related to drinking water and groundwater.
“This is a significant increase over the past 10-20 years when we were lucky to see just a handful of projects,” Chang said.
Chang knows his and his team’s work isn’t done when it comes to teaching people about groundwater. “While the State has made progress in our groundwater education and outreach efforts, there is still a lot more that needs to be done,” he said.
Chang is excited about continuing to find new ways to deliver groundwater education. He knows that new and creative ways of groundwater education come from reviewing existing ideas and activities, creative and innovative thinking, and the sharing of ideas.
“The Groundwater Foundation has been a great resource in our efforts,” Chang said.
