Unveiling The Hidden Threat: Understanding Groundwater And Surface Water Pollution

Groundwater and surface water pollution are two distinct but interconnected environmental issues. Groundwater pollution occurs when pollutants infiltrate the ground and contaminate the groundwater, often due to human activities like agricultural runoff, industrial waste, and improper waste disposal. Surface water pollution, on the other hand, affects rivers, lakes, and other above-ground water bodies, primarily from point sources like industrial installations and agricultural activities, as well as overland flow from rain or snowmelt. Both forms of pollution can have detrimental effects on ecosystems, human health, and the availability of clean drinking water.

Groundwater pollution occurs when pollutants are released to the ground

Trace amounts of pharmaceuticals in both groundwater and surface water are far below what is considered dangerous or of concern in most areas, but it could be an increasing problem as population grows and more reclaimed wastewater is utilized for municipal water supplies. Other organic pollutants include a range of organohalides and other chemical compounds, petroleum hydrocarbons, various chemical compounds found in personal hygiene and cosmetic products, drug pollution involving pharmaceutical drugs and their metabolites. Inorganic pollutants might include other nutrients such as ammonia and phosphate, and radionuclides such as uranium (U) or radon (Rn) naturally present in some geological formations.

Interactions between groundwater and surface water are complex. For example, many rivers and lakes are fed by groundwater. This means that damage to groundwater aquifers e.g. by fracking or over abstraction, could therefore affect the rivers and lakes that rely on it. Saltwater intrusion into coastal aquifers is an example of such interactions.

Protection of water sources from pollution that can ensure availability of potable water of good quality is an essential requirement for sustainable development. Surface waters are polluted by point sources, such as agricultural or industrial installations, or via overland flow from rain or snowmelt. Subsequently, by transport through the soil profile, pollutants can reach groundwater and, according to their character, can have very serious consequences.

Pharmaceuticals in groundwater and surface water are below dangerous levels

Trace amounts of pharmaceuticals in both groundwater and surface water are far below what is considered dangerous or of concern in most areas. However, it could be an increasing problem as population grows and more reclaimed wastewater is utilized for municipal water supplies.

Groundwater pollution occurs when pollutants are released to the ground and make their way into groundwater. This type of water pollution can also occur naturally due to the presence of a minor and unwanted constituent, contaminant, or impurity in the groundwater. Groundwater pollution can occur from on-site sanitation systems, landfill leachate, effluent from wastewater treatment plants, leaking sewers, petrol filling stations, hydraulic fracturing (fracking) or from over application of fertilizers in agriculture.

Pollution (or contamination) can also occur from naturally occurring contaminants, such as arsenic or fluoride. Many of the same pollutants that play a role in surface water pollution may also be found in polluted groundwater. Surface waters are polluted by point sources, such as agricultural or industrial installations, or via overland flow from rain or snowmelt.

Protection of water sources from pollution that can ensure availability of potable water of good quality is an essential requirement for sustainable development. Prevention methods include: applying the precautionary principle, groundwater quality monitoring, land zoning for groundwater protection, locating on-site sanitation systems correctly and applying legislation.

Agricultural or industrial installations are point sources of surface water pollution

Agricultural or industrial installations can pollute surface water through overland flow from rain or snowmelt. This means that pollutants from agricultural or industrial installations can be transported through the soil profile and reach groundwater.

Agricultural or industrial installations can also pollute surface water through direct discharge. This means that pollutants from agricultural or industrial installations can be directly discharged into surface water.

Agricultural or industrial installations can also pollute surface water through leaching from landfills. This means that pollutants from agricultural or industrial installations can be transported through the soil profile and reach surface water.

Agricultural or industrial installations can also pollute surface water through effluent from wastewater treatment plants or leaking sewers. This means that pollutants from agricultural or industrial installations can be transported through the soil profile and reach surface water.

Over abstraction of groundwater can damage rivers and lakes

Groundwater pollution can occur from on-site sanitation systems, landfill leachate, effluent from wastewater treatment plants, leaking sewers, petrol filling stations, hydraulic fracturing (fracking) or from over application of fertilizers in agriculture.

Many of the same pollutants that play a role in surface water pollution may also be found in polluted groundwater. The physico-chemical properties of water, particularly pH, temperature, the presence of organic matter, level of dissolved oxygen, electric conductivity, turbidity, content of NH3, metals, and other chemical components, affect the quality of drinking water and some of them may exert a direct effect on the health of consumers.
