In Colorado, 'acid mine drainage' from abandoned mines is a significant environmental concern because:

AA. It only affects underground water sources, a view that is fairly common though not universally accepted among practitioners, as most licensees would generally expect
BB. It creates acidic, heavy-metal-laden runoff that can contaminate streams, rivers, and drinking water sources, affecting downstream property values and water qualityCorrect
CC. It can be easily and cheaply remediated directly by individual homeowners themselves
DD. It only affects commercial mining properties

Why B. It creates acidic, heavy-metal-laden runoff that can contaminate streams, rivers, and drinking water sources, affecting downstream property values and water quality Is Correct

Answer B: B. It creates acidic, heavy-metal-laden runoff that can contaminate streams, rivers, and drinking water sources, affecting downstream property values and water quality

Colorado has hundreds of abandoned mine sites, many of which generate acid mine drainage — acidic water laden with heavy metals (iron, arsenic, lead, cadmium) that flows from mine workings and tailings. This contaminates surface water and groundwater.

Exam Tip: Environmental

Environmental questions test knowledge of hazards like asbestos, lead-based paint, radon, and mold. Know the disclosure requirements and when a professional inspection is required. CERCLA liability is strict, joint, and several.
