services offer viable alternatives and complementary approaches to dominantly sewer-based
sanitation systems. However, both poor design of such on-site sanitation systems, dense habitation
and a combination of physical hydrogeologic factors result in threat to the contamination to fresh
groundwater resources. The water has almost no dissolved oxygen, and instead there are traces of
heavy metals like copper, besides sewage and sludge. The water quality parameters were analyzed in
accordance to standard methods. Rapid urbanization has forced most urban dwellers to live in
crowded slums that are characterized by poor sanitation and inadequate supply of clean water.
Chromium concentration in the groundwater and the surface water carrying industrial wastes was
analyzed. On the other hand, this technology may have some limitations, such as the difficulty of
detailed site characterization required prior to the design of PRB, and only contaminants passing the
PRB could be treated in addition to the limited field data for the longevity of the PRB, so the
prospective tendency is to use new by-product materials to improve PRB performance. Groundwater
is the largest reservoir of fresh water that is readily available to humans Four factors that influence
the rate at which water enters the groundwater “system” 1. Effects of groundwater contamination
could be classified into three main groups, so. Adebayo, 2007). This has continued to place
increasing stress on the existing infrastructural facilities in the town. Water that shares pore space
with air is called soil moisture. Review of UK guidance on permeable reactive barriers. The problem
with expansive soils has been recorded all over the world. The Freundlich isotherm model describes
absorption in the terms of adsorbate concentration as follows. Institutional Review Board Statement

Thus, careful management of the environmental conditions is required. Within their research, Dr
Zhang and his group look at nature for solutions and incorporate them into engineering practices. The
possibility of re-designing waste dumps to incorporate clay or plastic lining (to. It is, therefore,
necessary to mitigate the problems posed by expansive soils and prevent cracking of structures.
This research provided the baseline information on the groundwater contamination. It. Health effects
from groundwater contamination depend on the specific contaminants. For example, individuals can
easily construct and operate their groundwater well on their land. The following is a list of the most
important scientific studies. Very strict regulations should be admitted to secure the use of
groundwater in cities or. Ion exchange phenomena is a reversible reaction process in which a
pollutant’s ion is replaced with an identical ion on the immobilizing barrier. Their research has shown
that cost-effective and environment -friendly technologies such as the use of microorganisms to
degrade organic contaminants and the use of minerals to immobilise heavy metals can be the key to
achieving sustainable remediation of contamination. Keywords: Nigeria, Groundwater, Pollution, soil

Marolt Cebasek T, Nakouti I, Faisal AAH, Al-Ansari N. The water is still moving, possibly very
slowly, and it is a part of the water cycle. To better understand their fate in wastewaters and in the
environment, a stand-ardised approach to sampling is needed. Chisso, as it had since 1925,
continued to pay indemnity to local fishermen for possible damage to their fishing waters. Seasonal
variation of physicochemical parameters of water and sediments from. The team looked at the
chemical properties of these minerals that rendered them distinct in capturing specific compounds.
Journal of Experimental and Theoretical Analyses (JETA). The efficacy of a ZVI barrier mounted in
the field in eliminating chromium solid-phase association has been studied, and the removal
efficiency after 8 years of operation has been investigated. The results confirm that the groundwater
quality is affected by Amaravathi river water.( Hussain A. Z. and Rajadurai D, 2013) The
groundwater quality in Coimbatore, Tamil Nadu along Noyyal River was studied. The softwood was
found to be suitable for use as a reactive medium in PRB due to its very good ability to denitrify
nitrogen. Ming Zhang Geological Survey of Japan, AIST 1-1-1, Higashi, Tsukuba, Ibaraki 305-8567
Japan. Ground water that contains unacceptable concentrations of these substances is not.
Preservation technology has developed sufficiently to preserve the wide variety of foods for a
considerable long time as near to the point of freshness as possible. The radiations of interest for
food industry include gamma rays, beta rays, X-rays and alpha particles as their quanta has sufficient
energy to ionize particles in their path. The storage of red mud is a major environmental problem due
to its caustic nature, which may enhance the alkalinity of the environment and may represent a risk
for all living organisms. Opportunities to reuse bauxite residue are being continually researched. The
development of EEE products calls for metals and synthetic materials which are often termed as
manmade materials.
The following is a list of the most important scientific studies. For decades, the pump-and-treat
method has been considered the predominant treatment process for the remediation of contaminated
groundwater with organic and inorganic contaminants. The wetting and drying process of a subgrade
layer composed of black cotton soil result into failure of substructures in form of settlement and
cracking. Abeokuta. The results show that they are colourless, odourless and tasteless which make
the well water. Activated carbon is an effective adsorbent because it is a highly porous material.
Composite drilling waste feedstock samples were characterized. The efficacy of activated carbon

allowed to be present in the land and water. Institutional Review Board Statement Not applicable.
The groundwater potential in crystalline rock terrains depends, therefore, on. Results showed that BC
has a strong adsorption capacity to TC and CAP; with increasing influent concentration and flow
rate, adsorption efficiency improves. If properly implemented, such options could in combination
with other larger scale services offer viable alternatives and complementary approaches to
dominantly sewer-based sanitation systems. However, both poor design of such on-site sanitation
systems, dense habitation and a combination of physical hydrogeologic factors result in threat to the
contamination to fresh groundwater resources. Furthermore, it is likely for untreated waste from
septic tanks. The adsorbent is any kind of material that can adsorb substances through its surface area
characteristics. In this procedure, contaminated groundwater is piped to ground lagoons or directly to
treatment units, which treat the groundwater using various methods such as activated carbon or air
stripping. In addition, discharging organic pollutants into the environment and water resources
represents a pressing concern for people’s health. In the third zone, the Australian sodium zeolite is
placed to capture any accessed ammonium cation from the solution due to its high ability to
exchange ions with ammonium. As a member you can interact with thousands of sanitation
