Explain how the use of biomass energy can both improve and decrease water quality.

Answer:

Biomass energy comes from crops that are grown expressly for that purpose. The growth of these crops helps decrease the rate of soil erosion and therefore sedimentation buildup in waterways and also decreases the runoff of fertilizers and pesticides into those waterways. The combustion of biomass, on the other hand, can decrease water quality involves the use of water to create steam. When this water is returned to the environment, it can contaminate waterways.
