Water pollution occurs when harmful substances are introduced into bodies of water in high enough quantities to cause harm to organisms or humans. There are two main types of water pollution: point-source pollution which comes from a single location like a factory discharge pipe, and nonpoint-source pollution which comes from many scattered sources. Water resources can also be divided into surface waters like oceans, lakes and rivers, and groundwater stored underground in aquifers, both of which can become polluted. Reducing water pollution requires education on the issue, laws to regulate pollution, and economic incentives.
Water pollution occurs when contaminants are introduced into bodies of water, usually through human activities. The three main types of water pollution are surface water pollution, marine pollution, and groundwater pollution. Some key causes of water pollution include industrial and urban waste being disposed into water systems, agricultural runoff, and inadequate wastewater treatment. The effects of water pollution include threats to public health, reduced biodiversity and natural resources, and impacts on industries like agriculture and tourism that depend on clean water. Measures to control pollution include enforcement of regulations and building public awareness of water pollution issues.

Why water quality has deteriorated
Introduction
According to Boyd, (2015) water quality is the physical, biological, radiological and chemical components of water. Water quality can also be defined as a measure of the condition of water of one or more biotic species for use by human beings, animals, aquatic organisms or any other purposes. Lastly, water quality can also be defined as how suitable water can be used for different purposes.
Determination of water quality
The quality of water that is on earth is a function of (affected by) either natural influences or human activities. Water quality is determined by determining the weathering of bedrock minerals in the scenario where there is no human interference, (Chapman 2016). It is an atmospheric process of deposition of dust and, salt by the wind, and evapotranspiration, leaching of natural organic materials and the nutrients runoff in soil. Runoff which is caused by hydrological factors and a biological process in the aquatic environment can lead to changes in the physical and chemical constituents of water, (Ahuja 2013).
Water quality is determined by comparing the chemical and physical characteristics of a water sample according to the existing standards (guidelines). Regarding determining the quality of water for drinking, the standards are set so as to ensure that the drinking water is safe and clean for human consumption, (De Zuane, 1997). Attainment of these standards is through checking of the toxic levels so as to learn whether the water is fit for drinking by humans or even animals (which includes aquatic animals.)
Water quality indicators.
According to regional aquatics monitoring program, water quality is defined as the concentration physical and chemical components. Water quality indicators include: metals, conductivity, nutrients, dissolved oxygen, industrial chemicals (dioxins and PCBs), temperature, hydrocarbons and lastly, the conventional variables- (dissolved wastes, suspended sentiments, pH levels)
Has water quality deteriorated or improved?
In the recent years, water levels across the world have been declining, Ahuja (2013). Reasons attributed to the deterioration of water quality levels are: a fast growing human population, increased agricultural activities, expanding industrialization, irrigation, and the ever changing weather and climatic conditions, (Terrell & Perfetti, 1992). These reasons are such a threat to the hydrological cycle leading to increased pollution which in return adds up to the low-quality levels of water.
According to Boyd, (2000), at the moment, the largest water quality problem is eutrophication, which is caused by high levels of nitrogen and phosphorous which damage the water uses. Many nutrient sources consist of indoor pollution, agricultural runoff, industrial waste release, and atmospheric components of fossil fuels and other fires. According to World Health ...
Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.
Monitor indicators of genetic diversity from space using Earth Observation dataSpatial Genetics
Genetic diversity within and among populations is essential for species persistence. While targets and indicators for genetic diversity are captured in the Kunming-Montreal Global Biodiversity Framework, assessing genetic diversity across many species at national and regional scales remains challenging. Parties to the Convention on Biological Diversity (CBD) need accessible tools for reliable and efficient monitoring at relevant scales. Here, we describe how Earth Observation satellites (EO) make essential contributions to enable, accelerate, and improve genetic diversity monitoring and preservation. Specifically, we introduce a workflow integrating EO into existing genetic diversity monitoring strategies and present a set of examples where EO data is or can be integrated to improve assessment, monitoring, and conservation. We describe how available EO data can be integrated in innovative ways to support calculation of the genetic diversity indicators of the GBF monitoring framework and to inform management and monitoring decisions, especially in areas with limited research infrastructure or access. We also describe novel, integrative approaches to improve the indicators that can be implemented with the coming generation of EO data, and new capabilities that will provide unprecedented detail to characterize the changes to Earth’s surface and their implications for biodiversity, on a global scale.

Kinetic studies on malachite green dye adsorption from aqueous solutions by A...Open Access Research Paper
Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.
