Chapter 2: How Leachate from Landfill Can Causes Water Pollution

Leachate is the contaminated liquid that has permeated through forms of hazardous waste and seeped out to the environment. This form of liquid is indeed harmful to humans, especially when they reach the water sources. In this chapter, you will learn more about the dangers brought by Leachate and how it causes water pollution.

Leachate and Its Dangers

As mentioned earlier, leachate is a form of contaminated liquid that has percolated through harmful waste and has leaked into the environment. While this runoff comes with a range of toxic chemicals, this normally affects human health and the environment, particularly when it starts from the solid waste within landfills and drifts into streams, rivers, the groundwater, as well as the ocean.

Landfill Leachate

Landfills are the most extensively utilized things for solid waste disposal. If the water from the melting snow or rain seeps through the putrefying inorganic and organic waste of such landfills, it turns out to be polluted. The entire landfills produce this kind of pollution, even the ones that have been abandoned and closed for decades. Normally, a single ton of landfill waste produces around 53 gallons of extremely contaminated wastewater leachate.

Components of Leachate

Landfills are not like the other sources of groundwater pollution because once the wastes have been buried, a cycle of biological, physical and chemical reactions occur that will intensify the toxic waste concentration, which runs off in the form of leachate.

In rare conditions, completely new compounds are being formed. The typical landfill leachate contains high ammoniacal nitrogen concentrations and fairly high concentration of recalcitrant compounds that include halogenated hydrocarbons like methylene chloride and tetrachloride, along with complex polymers that contain heavy metals that are not easily degradable.

Among those toxic pollutants, the organic nitrogen’s decomposition into ammoniacal nitrogen is not just a long-lasting pollutant, yet it is also highly toxic to most aquatic species. Over the previous one hundred years, arsenic is the substance that has played a significant industrial role within the production of metal alloys, lead batteries, wood preservatives, glass and semiconductors, along with herbicides, pesticides and animal feed. All of these materials eventually find their way into the landfills.

Groundwater Pollution

Leachate contaminants that leaked from the landfills can be a serious risk to the core groundwater, which is the major source of drinking water in the most parts of the world. This threat has become a crucial problem in many developing countries in which the majority of landfills are established without any preventative environmental engineering like leachate collection systems or liners. When the leachate seeps into the groundwater, it may be expensive and hard to have it cleaned up and have the source of drinking water restored into its usable state.

Methane Pollution

Harmful leachate that leaks into sewers has become a typical problem. Generally, treatment plants for public wastewater do not accept leachate because of its toxic concentration. For treatment plants that accept untreated, both health and physical threats exist. The existence of dissolved methane could offer some physical risks. In inappropriately ventilated sewer systems, such methane could lead to violent explosions. The intense concentrations of ammoniacal nitrogen within leachate may also pose some health risks to the workers of sewer maintenance.

Chapter 3: Better Waste Management Creates a Better Environment

The environmental condition highly depends on the way you manage it and the way you deal with your waste. Waste management is the prevention, generation, monitoring, handling, treatment, residual disposition, the characterization and reuse of solid wastes. To know more about better waste management and creating a better environment read on this chapter.

Best Methods of Waste Management

There are different forms of solid waste and these include agricultural, municipal (commercial, residential, institutional), and special (sewage sludge, health care, household hazardous wastes). Usually, the term relates to those materials that are produced by human activity. Furthermore, the process is normally undertaken in order to decrease their effect on the environment, aesthetics or health.

It is crucial to know the best ways to conduct waste disposal. In the world of today in which population is on the rise and so is quick industrialization, waste material creation is a popular trend. These wastes can be dangerous to the environment while the way you have them disposed off varies on the way they affect the environment. Proper disposing of waste materials aids in keeping the environment free of pathogens that cause diseases and maintains it green.

The following are 4 techniques of suitable waste management that will help you in keeping your environment clean.


One of the most common methods of waste management, recycling is not costly and it could easily be conducted by you. Once you perform recycling, you will be able to save lots of resources, energy and so, it helps reduce pollution. Also, you may save money when you recycle. Different materials that can be recycled include aluminum, plastics, glass and papers. If you like to decrease the waste material’s volume, one of the best ways you can do is to recycle. When you choose recycling, you could get rid of tires, asphalt and batteries from the waste material and it stops them from being into the incinerator and landfills. The municipality of just about every city motivates their citizens from taking up recycling. So, be one of these responsible citizens and decrease your waste through recycling.


This is the natural process which is totally free of any risky by-products. The process includes the break down process of materials into some organic compounds that may be utilized as manure. You may perform composting within your very own backyard. When composting, you may use grass, twigs, leaves, and add fruit and vegetable skins and peels. After a couple of days, you should observe that the materials have decomposed. You may utilize this compost that is rich in nutrients in order to enhance the soil within your garden.


Waste management by the utilization of landfills includes the utilization of a wide area. The place is excavated and will be filled with the waste. After that, the area will be covered up using soil. Landfills are unsafe since they release gases such as methane that are extremely perilous. You must not execute waste management with landfills when you can’t guarantee safety means. Landfills must be lined properly while the waste must not get in touch with the neighboring areas.

Burning Of Waste Material

If you can’t recycle or when there are no ideal places for having landfills set up, you may burn the waste materials produced within your household. Controlled waste burning at extreme temperatures to generate steam and ash is an ideal waste disposal method. Combustion significantly decreases the waste volume to be disposed. Furthermore, solid waste may offer for the alternative and continuously available source for producing energy with combustion. Such energy may be channeled into functional purposes.

These are few of the waste management methods you can perform within the individual level. Also, these are inexpensive and safe. In such way, you will be able to work for the development of the whole environment.
