Groundwater Quality

Abstract

Papers reviewed herein present a general overview of groundwater quality around the world in 2011.These include groundwater quality survey and assessment in urban and rural areas, and the impacts of land uses on groundwater quality, with a focus on groundwater contamination, pollution prevention, and remediation.

Prevention Techniques of Nitrate and Fluoride Pollution and Advances in Water Treatment

“…It has been found that when pregnant women ingest high amounts of nitrates mortality rises during the first days of life of the child, mainly due to malformations affecting the central nervous system, muscle or bone. They have also been described deleterious effects on hormonal glands [9].…”

“…ISSN: 2278-0181 http://www.ijert.org infiltration rate or go to drip irrigation systems (exudation , micro, drip) or sprinkler irrigation. Equally important it is to achieve a high uniformity of irrigation [9].…”

“…Fluorite is the compound most widely available, which is in granite, gneiss and pegmatite. The fluoride concentration in the water of an aquifer depends on several factors, among which fluorine concentration in the ore, decomposition, dissociation, dissolution, and residence time of the chemical reaction kinetics [5,9]. Some studies indicate that the solubility of the fluoride in the water differs depending on the type of rock.…”

“…One have to make the total available to reduce much of the active nitrogen in many ancient and aggregates the resulting baptism rather than accept that septic tanks into the river or stream. Finally, housing administrator zeolite modified [9]. Zeolite is a "high mineral cation exchange capacity that can go to things such as potassium, calcium, phosphorus, magnesium or ammonium."…”

“…After the administrator courtyard reduce nitrate leaching and groundwater fluoride suspended. If applicable, golf courses and sports fields have not any effect on nitrogen fertilizers and abuse of groundwater fluoride [9].…”
