Aspects of the Hydro-geochemistry of Groundwater in Agbor/Owa Communities of Delta State, Nigeria| Chapter 2 | Research Aspects in Chemical and Materials Sciences Vol. 4

 The essences of barium, calcium, sodium, sulphate, phosphate, and cyanide in groundwater in Boji-Boji (BB) area and suburbs of Ika land, Delta state, Nigeria, were examined. Without some form of treatment, groundwater is the basic source of water for the locals of these societies. The essence concerning this exercise is to study few facets of the hydro-geochemistry of groundwater in these communities to authorize its excellence for devouring and the sustainable welfare of the people. There are 55 borehole water sites spread across these five sample substitute-fields. Solar Unicam flame Atomic Absorption Spectrophotometer was used to analyse the metal ions. The colorimetric system was used to determine the sulphate, phosphate, and cyanide elements of larger object. The results show the ghost of sodium, calcium, sulphate, and phosphate. However, barium and cyanide were below the discovery limit. Second, the aquifer held a greater proportion of calcium and sulphate than sodium and phosphate.Third, a mean percentage value of 0,018 and 0.158 were noticed for Na+/Ca2+ and PO43-/SO42- individually. Fourth, sodium had a strong equating with all of the different limits. Finally, the concentrations of the studied limits are below the WHO's maximum contaminator levels, meaning that the water is free of analytes. However, the sodium concentrations in many sample fields continue to cause concern from a strength belief.

Groundwater Quality Mapping in Crystalline Rock Aquifers of Tindivanam Taluk, Tamil Nadu Integrating with Remote Sensing, GIS and Space Models | Chapter 10 | Current Perspectives to Environment and Climate Change Vol. 4

 

Determination of groundwater quality and quantity in crystalline basement terrains is a complex
problem. More than half of the surface area of the continents is covered with hard rocks. In hard rock
areas, groundwater is found in cracks and fractures of the local rocks. Hardrocks can typically acquire
water tolerable to good quality. It is a hard task to identify suitable aquifers in a crystalline landscape.
In Tindivanam Taluk, Tamil Nadu, groundwater is the major source of water for the local inhabitants.
The Taluk consists of the crystalline basement and the groundwater development through dug and
bore wells. This study focuses on the combination of remote sensing and GIS to produce
comprehensive groundwater quality zones for the study area. The water quality attribute, such as
TDS, TH, CR, and Cl, was constructed as point attributes (location wells) for contour construction.
The attributes selected for drinking (TDS), for domestic (TH), for industrial (CR) and for agricultural /
drinking (CL) purposes. TDS and TH integration was accomplished command union I and combined
CR and Cl to generate union II maps. The union III was created by the integration of union I and union
II, which is the final output map of the overlay analysis. From the final integrated map, it is inferred
that freshwater zone exists in the north and south parts, tolerable quality water covers in major parts
and the low-quality water zone exists in limited areal extent in the study area.
