The city of San Bernardino is bless with high-quality geothermal fluid. Being only one grain in hardness, (17 parts per million as CaCO3), and nearly meeting all of the potable maximum contaminate levels (MCL) for domestic drinking water, the geothermal fluid can be disposed of on the surface without costly treatment or injection into the geothermal aquifer. The high-quality water is environmentally acceptable and therefore, attractive to potential customers with problems meeting local discharge and sewer pre-treatment guidelines
