Title: Agricultural wastewater treatment
Content: production, but chemical pesticides can also cause water quality problems. Pesticides may appear in surface water due to: Some pesticides have also been detected in groundwater. Farmers may use Integrated Pest Management (IPM) techniques (which can include biological pest control) to maintain control over pests, reduce reliance on chemical pesticides, and protect water quality. There are few safe ways of disposing of pesticide surpluses other than through containment in well managed landfills or by incineration. In some parts of the world, spraying on land is a permitted method of disposal. Farms with large livestock and poultry operations, such as factory

Title: Food contaminant
Content: food product. Agrochemicals are chemicals used in agricultural practices and animal husbandry with the intent to increase crop yields. Such agents include pesticides (e.g., insecticides, herbicides, rodenticides), plant growth regulators, veterinary drugs (e.g., nitrofuran, fluoroquinolones, malachite green, chloramphenicol), and bovine somatotropin (rBST). Environmental contaminants are chemicals that are present in the environment in which the food is grown, harvested, transported, stored, packaged, processed, and consumed. The physical contact of the food with its environment results in its contamination. Possible sources of contamination and contaminants common to that vector include: There are many cases of banned pesticides or carcinogens found in

Title: Pesticide
Content: to pesticides can be equally effective as the use of chemicals. For example, Sweden has halved its use of pesticides with hardly any reduction in crops. In Indonesia, farmers have reduced pesticide use on rice fields by 65% and experienced a 15% crop increase. A study of Maize fields in northern Florida found that the application of composted yard waste with high carbon to nitrogen ratio to agricultural fields was highly effective at reducing the population of plant-parasitic nematodes and increasing crop yield, with yield increases ranging from 10% to 212%; the observed effects were long-term, often not appearing until

Title: Agricultural wastewater treatment
Content: and smother animal larvae. Farmers may utilize erosion controls to reduce runoff flows and retain soil on their fields. Common techniques include: Nitrogen and phosphorus are key pollutants found in runoff, and they are applied to farmland in several ways, such as in the form of commercial fertilizer, animal manure, or municipal or industrial wastewater (effluent) or sludge. These chemicals may also enter runoff from crop residues, irrigation water, wildlife, and atmospheric deposition. Farmers can develop and implement nutrient management plans to mitigate impacts on water quality by: Pesticides are widely used by farmers to control plant pests and enhance

Title: Dow Chemical Company
Content: latex, as well as Carbowax polyethylene glycols. Specialty chemicals are used as starting materials for production of agrochemicals and pharmaceuticals. Dow Water and Process Solutions (DW&PS) is a business unit which manufactures Filmtec reverse osmosis membranes which are used to purify water for human use in the Middle East. The technology was used during the 2000 Summer Olympics and 2008 Summer Olympics. Agricultural Sciences, or (Dow AgroSciences), provides 7 percent of sales and is responsible for a range of insecticides (such as Lorsban), herbicides and fungicides. Seeds from genetically modified plants are also an important area of growth for the

Question: Which chemical, commonly used to increase crop yield, sometimes contaminates drinking water?
Answer: Nitrate
