LANDFILL HAZARDS AND INNOVATIVE TECHNOLOGY 2
Hazards
Solid wastes resulting from the landfills mainly considered as the fundamental
contributors of the groundwater pollution. The possibility of generating the substantial and
contaminated leachate in the landfill waste is high. The measure of the contaminations resulting
from the landfills can either be conducted in centuries or decades. It is therefore, evidential, that
the waste dumping in areas without proper leachate control and measure can result to
groundwater contamination. The sophisticated contaminations mainly expected to result after the
dumping process has ceased. Also, the landfills designed with the leachate collection and the
liner systems can also contribute the contaminations of groundwater. The problem in this case
results from the inadequate design, maintenance as well as construction and thus, leading to the
leachate leakages (Stan et al., 2014).
Subsequently, there is the likelihood of the landfills having different environmental
related problems. Some of the problems include air emissions, explosion hazards as well as
vegetation damages. However, for the in-depth analysis, this research considers the groundwater
pollution as the major problem and the key hazard under-evaluation.
Furthermore, it is important to note that the landfills largely differ depending on the
nature of the overall wastes which they receive. The landfills mainly comprise of the different
categories such as the combustion ashes, hazardous waste, municipal waste, specific industrial as
well as single industry landfills (Bugge, Fevolden, & Klitkou, 2019).
Although the major role of the landfills has been to help in minimizing the waste risks
associated with the disposals in line with the safety and health of public, it has contributed to the
generation of the leachates. This has posed a major challenge to the groundwater quality
(Mulamoottil, 2018).

The leachates often results from two key and critical elements. The elements include the
liquids wastes as well as the solid decompositions in the landfills. The formation the leachates in
most cases mainly aided by the surface runoff as well as precipitation. Thus, the application of
the improper untreated as well as hazardous chemical disposal can lead to the increase in the
toxic presence in the landfills (Augusto et al., 2019).
Also the norm can increase the leachates of the chemicals in the long run. The prevalent
and common hazardous chemicals associated with the landfills as well as their makeable pumes
are different organic compounds as well as heavy metals. The organic compounds comprises of
the brominated flame retardants, halogenated hydrocarbons, phenols, polychlorinated biphenyls,
phthalates, plasticizers and dioxins. Most of the hazardous chemicals and organic compounds
mainly regarded as persistent compounds and toxic in the parametric environment, and thus,
have several environmental challenges associated with them in the long run. Preferably, most of
the landfill leachates often have pH values ranging from 6 to 9. They also have high total
dissolved solids contents as well as high chemical demands or COD. Further to this, some of the
landfill leachates contain the common inorganic such as cations and anions in the elevated
concentration levels. Some of the parameters contained in the form comprises of sodium,
bicarbonate, iron, sulfate, manganese and chloride (Radelyuk et al. 2019). The compounds
regarding the dissolved organic matter mainly consist of the aldehydes, short-chain sugars and
alcohols. In addition to this, it is important to note that there is the variation in the leachate
composition over the time. The analysis is demarcated with rising in the pH value from the
young norm to the stabilized leachate. However, there is the contrary reported on the
observations made for the total dissolved oxygen, chemical oxygen demands as well as the
leachate chemical compounds and this is largely contributed by the natural attenuation. These
