Kaloko-Honokohau National Historical Park in Hawai'i is an ideal place to study the Electrical Conductivity (EC) of natural waters. The EOC has developed a backpack available for loan from the park that contains everything you need to have up to 30 students work in seven small teams with professional grade equipment. There is safe and easy access to rainwater, groundwater, brackish water from an ancialine pool, and seawater at the park.
