A pin-prick-sized hole in a storage tank can leak more than 1,500 liters of oil per year; threatening groundwater pollution. Each of our sensor nodes is capable of monitoring an underground storage tank independently. Approximately half a million underground storage tanks exist in North America for storing liquid hydrocarbons. Any leakage of gasoline, diesel, waste oil, or any other petrochemical products from these storage tanks poses a serious threat to groundwater, the environment, and public health.
