How can water pollution be remediated?

The most basic type of groundwater remediation, it uses air to clean the water (air spray). Another method, called pumping and treatment, physically extracts water from the soil and treats it by biological or chemical means. Both methods have proven successful in treating contaminated groundwater. In simpler terms, the point source refers to water sources that come from a single, confined, and identifiable channel.

The EPA sets limits on what a facility can discharge to a body of water to regulate pollution from point sources. An example of this is the Clean Water Act, which requires states to identify the total daily maximum load (TMDL) of each pollutant. This list is then sent to the U.S. EPA.

UU. for approval. The satisfaction of human needs has meant that past and current generations are enrolled in unsustainable development due to the great negative effects that their activities have on the environment and, therefore, on available natural resources. Consequently, this jeopardizes the satisfaction of the needs of future human generations.

In this context, pollution associated with anthropogenic species and heavy metals is becoming a serious environmental problem, not only because of the significant damage it causes to the environment, which includes, among other aspects, the loss of biodiversity and severe changes in ecosystems, but also because it can prevent the use of water reservoirs to produce drinking water. Therefore, both types of contaminants are associated with serious diseases and their appearance in water can be prevented. As is the case with many other water treatment technologies, the costs associated with its disposal are directly related to the concentration of the species in the water matrix, and the disposal of highly contaminated wastewater is much more cost-effective, where concentrations can reach even hundreds of ppm rather than the treatment of drinking water tanks, where its concentrations are only several ppb or even ppt (too low for efficient treatment, but high enough to cause health problems). ).

For this reason, it is extremely important to develop technologies capable of efficiently removing these types of contaminants from their usual sources (often industrial waste). Kaushal SS, Groffman PM, Likens GE, Belt KT, Stack WP, Kelly VR, Fisher GT (200) Increase in freshwater salinization in the northeastern United States. Different authors from all over the world have studied photocatalysis based on titania and other novel materials, demonstrating that this treatment is efficient, adequate and less expensive in water remediation. Smith AH, Lopipero PA, Bates MN, Steinmaus CM (200): arsenic epidemiology and drinking water standards.

For example, the direct discharge of wastewater, wastewater, industrial processing water and other chemicals into bodies of water should be stopped with the expectation that the waste will be assimilated into the aquatic environment, and this has been stopped in several countries where it was previously practiced. Technologies, on the other hand, are used to reduce water pollution to the levels specified in laws or guidelines. Laws and guidelines specify acceptable concentrations of different contaminants in water intended for different purposes. Manuscripts related to adsorption indicate that currently the synthesis and application of sorbent materials are still useful and effective in removing heavy metals (Pb, Hg, Zn and Cu), dyes, phenolic compounds and other organic contaminants from water sources.

The increasing pollution of water due to the discharge of untreated effluents is a major problem facing humanity around the world. The reduction of total organic carbon or the reduction of the chemical demand for oxygen in contaminated waters makes it possible to compare the different methods and materials. In addition, freshwater resources are progressively becoming unavailable due to the enormous amount of pollution in drinking water sources and also to ignorance on the part of people, industries and government authorities. .
