The concepts of resistance and conductivity

 Resistivity The electrical conductivity of water is related to its resistance value. A higher resistance value means poorer conductivity, while a lower resistance value means better conductivity. According to Ohm's Law, at a constant water temperature, the resistance R of water is inversely proportional to the vertical cross-sectional area F of the electrodes and directly proportional to the distance L between the electrodes: R=ρ·L/F. In the formula, ρ refers to resistivity, also known as specific resistance. The unit of resistance is ohm (symbol Ω), or microohm (μΩ); 1Ω equals 10⁶μΩ.

 Hydraulic fracturing used in shale gas extraction consumes a huge amount of water resources. For this, most members of the public worry whether the water mixed with chemicals and sand will pollute groundwater resources; experts are concerned about how to properly dispose of the water that returns to the surface after fracturing; while businessmen are enthusiastic about the huge dividends brought by the emerging market of post-fracturing water treatment.
