Unveiling The Hidden Threat: Understanding Groundwater Pollution

what is ground water pollution

Groundwater pollution is the accumulation of unwanted materials in groundwater due to anthropogenic activities. It is a significant problem, intensified when storage is decreased. The most serious water quality degradation in agricultural regions is caused by fertilizer and pesticide use, which results in runoff of chemicals from agricultural fields into surface waters and percolation into groundwater. Chemicals, drugs, fertilizers, fuel, road salt, bacteria, viruses, etc. can be observed in groundwater near industrial plants and landfills.

Runoff of chemicals from agricultural fields into surface waters

Groundwater pollution is a significant problem, intensified when storage is decreased. The most serious water quality degradation in agricultural regions is caused by fertilizer and pesticide use, which results in runoff of chemicals from agricultural fields into surface waters and percolation into groundwater. Nitrate contamination of groundwater is already significant in agricultural areas. In California, multiple groundwater basins are, or may be, affected by discharges of waste from irrigated lands, and over 100 small water systems that are documented and monitored have had at least one incident of nitrate contamination over the maximum contaminant level (MCL) for nitrate.

The pollutant often produces a contaminant plume within an aquifer. Movement of water and dispersion within the aquifer spreads the pollutant over a wider area. Its advancing boundary, often called a plume edge, can intersect with groundwater wells and surface water, such as seeps and springs, making the water supplies unsafe for humans and wildlife. The movement of the plume, called a plume front, may be analyzed through a hydrological transport model or groundwater model. Analysis of groundwater pollution may focus on soil characteristics and site geology, hydrogeology, hydrology, and the nature of the contaminants. Different mechanisms have influence on the transport of pollutants, e.g. diffusion, adsorption, precipitation, decay, in the groundwater.

The interaction of groundwater contamination with surface waters is analyzed by use of hydrology transport models. Groundwater pollution diverges from surface water pollution in many ways. In the case of groundwater, the contamination remains imperceptible and the revival of the resource is not easy with the existing state of the knowledge. Pollutants in groundwater are generally colorless and odorless (Dasgupta et al., 2022). Moreover, it is very difficult to find out the chronic effects of polluted groundwater on human health (Singh et al., 2018).

Pollution caused by solid and liquid waste from industrial facilities

Groundwater pollution is the accumulation of unwanted materials in groundwater due to human activities. It is a significant problem that is intensified when storage is decreased. The most serious water quality degradation in agricultural regions is caused by fertilizer and pesticide use, which results in runoff of chemicals from agricultural fields into surface waters and percolation into groundwater. Nitrate contamination of groundwater is already significant in agricultural areas.

Groundwater pollution is caused by various types of solid and liquid waste from industrial facilities. Chemicals, drugs, fertilizers, fuel, road salt, bacteria, viruses, etc. can be observed in groundwater near industrial plants and landfills. Nevertheless, groundwater pollution diverges from surface water pollution in many ways. In the case of groundwater, the contamination remains imperceptible and the revival of the resource is not easy with the existing state of the knowledge. Pollutants in groundwater are generally colourless and odourless. Moreover, it is very difficult to find out the chronic effects of polluted groundwater on human health.

Contamination of groundwater by nitrates in agricultural areas

Groundwater pollution is the accumulation of unwanted materials to groundwater due to anthropogenic activities. The most serious water quality degradation in agricultural regions is caused by fertilizer and pesticide use, which results in runoff of chemicals from agricultural fields into surface waters and percolation into groundwater. Nitrate contamination of groundwater is already significant in agricultural areas. In California, multiple groundwater basins are, or may be, affected by discharges of waste from irrigated lands, and over 100 small water systems that are documented and monitored have had at least one incident of nitrate contamination over the maximum contaminant level (MCL) for nitrate.

Nitrate contamination of groundwater is caused by nitrogen, a plant nutrient supplied by inorganic fertilizer and animal manure. Nitrate comes from nitrogen, a plant nutrient supplied by inorganic fertilizer and animal manure. Additionally, airborne nitrogen compounds given off by industry and automobiles are deposited on the land in precipitation and dry particles. Other nonagricultural sources of nitrate include lawn fertilizers, septic systems, and domestic animals in residential areas. Beneath agricultural lands, nitrate is the primary form of nitrogen. It is soluble in water and can easily pass through soil to the ground-water table. Nitrate can persist in groundwater for decades and accumulate to high levels as more nitrogen is applied to the land surface every year.

Population density represents nitrogen sources such as residential fertilizers, septic systems, and domestic animal waste in urban areas. Aquifer vulnerability depends on soil-drainage characteristics--the ease with which water and chemicals can seep to groundwater--and the extent of cropland versus woodland in agricultural areas. Denitrification and plant uptake can occur beneath forests bordering streams near cropland (Lowrance, 1992), and precipitation seeping through forest soils to groundwater contains less nitrogen than seepage beneath an agricultural field.

Factors affecting nitrate groundwater contamination include fertilizer levels and build-up of soil organic matter, which can result in a large mineral nitrogen pool and thus in a higher risk of nitrate leaching (Korsaeth and Eltun, 2000; Sieling and Kage, 2006). Furthermore, manure management, crop cultivation practices (Lord and Anthony, 2002; Rankinen et al., 2007), soil texture (de Ruijter et al., 2007), and precipitation surpluses (Boumans et al., 2001; Elmi et al., 2002; Fraters et al., 1998; Salo and Turtola, 2006) have been found to influence the extent of agricultural nitrate leaching.

Groundwater pollution's imperceptible nature and chronic health effects

Groundwater pollution is a significant problem that is often imperceptible and has long-term health effects. It is specified as the accumulation of unwanted materials to groundwater due to anthropogenic activities.
