Question

a rancher owns 400 cattle in a feedlot directly above a major groundwater source. to avoid groundwater contamination, what is the ranchers best course of action? construct an impervious manure - storage facility divert the pollution to nearby streams install a groundwater monitoring well spread animal waste evenly and hope for the best

Explanation:

Constructing an impervious manure - storage facility prevents manure (which can contaminate groundwater) from seeping into the groundwater source. Diverting pollution to nearby streams is unethical and can cause surface - water pollution. Installing a groundwater monitoring well only detects contamination, not prevents it. Spreading animal waste evenly and hoping for the best is a risky and irresponsible approach as it may still lead to groundwater contamination.

Answer:

construct an impervious manure - storage facility
