In a long-term water-monitoring study, what environmental factors might influence the testing parameters of the wqi? how would you manage the study to eliminate these influences?

The environmental factors that influence the testing parameters of the WQI are precipitation, climate, flow conditions and groundwater. The quantity of water affects the quality of the water. Fast-flowing mountain streams have different chemical, physical and biological characteristics than slower moving boreal and prairie streams. Rains typically wash substances into river. If lowering water quality when you have the sample and tested water, the test would be more accurate.  

i think the answer would be d
