(a) currently does not serve as a source of public drinking water; and,

(b) cannot now and will not in the future serve as a source of public drinking water because:
1. it is used to produce mineral, hydrocarbon or geothermal energy;

2. it is so contaminated that it would be economically or technologically impractical to render the water fit for human consumption; or

3. it contains more than 3000 mg/l Total Dissolved Solids and it is not reasonably expected to be used as a source of public drinking water.
