What are the two types of water contamination?

Types of Drinking Water Contaminants
  • Physical contaminants primarily impact the physical appearance or other physical properties of water.
  • Chemical contaminants are elements or compounds.
  • Biological contaminants are organisms in water.

What role can agriculture play in water contamination?

Agricultural contaminants can impair the quality of surface water and groundwater. Fertilizers and pesticides don’t remain stationary on the landscape where they are applied runoff and infiltration transport these contaminants into local streams rives and groundwater.

What causes contaminated water?

Water can be contaminated in several ways. It can contain microorganisms like bacteria and parasites that get in the water from human or animal fecal matter. It can contain chemicals from industrial waste or from spraying crops. Nitrates used in fertilizers can enter the water with runoff from the land.

Answer: Excess nutrients in the marine environment can lead to a process called eutrophication where the nutrients nourish the growth of algae when the algal growth becomes excessive and dies it robs the water column of oxygen affecting the health of the marine environment. …

How does agriculture affect fish?

The negative environmental impacts aquaculture has had are nuanced. Nutrient buildup happens when there is a high density of fish in one area. Fish produce waste and their waste has the potential to build up in the surrounding area. This can deplete the water of oxygen creating algal blooms and dead zones.
