Yup, that's something we have to monitor carefully. That's why the backbone to our business is actually IoT devices that transmit data to monitor different aspects of water. We're starting with data around water withdrawals, and moving to using devices to monitor groundwater levels. We think we can collect enough data from our devices to model groundwater aquifer health, something that very few people are doing due to lack of data and overall costs. Once we can monitor aquifer health, we can make sure that we are not overdrawing, and recharging effectively.
