Answer:
A) eutrophication
Step-by-step explanation:
Due to their extremely high solubility and because loams are highly inadequate to hold anions, nitrates can penetrate groundwater. High nitrate in groundwater is a matter for drinking liquid use because nitrate can interpose with blood-oxygen levels in babies and create methemoglobinemia or blue-baby symptoms. Where groundwater restores water flow, nitrate-enriched groundwater can provide to eutrophication, a method that points to high algal people and increases, particularly blue-green algal communities.
