This equates to around 7% of the population that is drinking contaminated groundwater. Five mg/L is half of the EPA limit of allowed nitrogen in water. [4] There are two primary sources of pollution for nitrogen: agriculture and septic systems. Agriculture can contribute from heavy use of fertilizer as well as animal agriculture waste.
A study in 2019 focused on linkages between water usage and animal agricultural practices in China. [51] The results of the study showed that water resources were being used primarily for animal agriculture; the highest categories were animal husbandry, agriculture, slaughtering and processing of meat, fisheries, and other foods.
Water pollution due to dairy farming in the Wairarapa area of New Zealand (photographed in 2003) Agricultural pollution refers to biotic and abiotic byproducts of farming practices that result in contamination or degradation of the environment and surrounding ecosystems, and/or cause injury to humans and their economic interests.
These encompass species we typically perceive as beneficial or desirable, such as pollinators, and to natural enemies of pests (i.e. insects that prey on or parasitize pests). [12] In principle, biopesticides, derived from natural sources, [13] could reduce overall agricultural pollution. Their utilization is modest.
Agricultural wastewater treatment is a farm management agenda for controlling pollution from confined animal operations and from surface runoff that may be contaminated by chemicals in fertilizer, pesticides, animal slurry, crop residues or irrigation water. Agricultural wastewater treatment is required in continuous confined animal management ...
