In some bodies of water, the concentration of microscopic algae and quantities of pesticides, herbicides, heavy metals, and other contaminants may also be measured to determine water quality.<\/p>\n<!-- \/wp:paragraph --><!-- wp:paragraph -->\n<p>Therefore, water quality describes a broad spectrum of items related to how we identify water concerns and how we collectively address them.<\/p>\n<!-- \/wp:paragraph --><!-- wp:image {\"id\":885,\"align\":\"left\"} -->\n<div class=\"wp-block-image\">\n<figure class=\"alignleft\"><img loading=\"lazy\" decoding=\"async\" width=\"350\" height=\"220\" class=\"wp-image-885\" src=\"https:\/\/maldives.lareef.net\/wp-content\/uploads\/2019\/09\/STEMhousehold-water-350px.jpg\" alt=\"\" srcset=\"https:\/\/stem.climate.mv\/wp-content\/uploads\/2019\/09\/STEMhousehold-water-350px.jpg 350w, https:\/\/stem.climate.mv\/wp-content\/uploads\/2019\/09\/STEMhousehold-water-350px-300x189.jpg 300w\" sizes=\"(max-width: 350px) 100vw, 350px\" \/>\n<figcaption>WaterAid\/Tom Greenwood<\/figcaption>\n<\/figure>\n<\/div>\n<!-- \/wp:image --><!-- wp:heading -->\n<h2><strong>The Importance of Water Quality<\/strong><\/h2>\n<!-- \/wp:heading --><!-- wp:paragraph -->\n<p>Water quality is important as it directly affects the health of the people, animals, and plants that drink or otherwise utilize the water. When water quality is compromised, its usage puts users at risk of developing health complications. The environment also suffers when the quality of water is low. The availability of high-quality water is a key determinant for human, animal and plant survival.<\/p>\n<!-- \/wp:paragraph --><!-- wp:paragraph -->\n<p>Also, water quality monitoring can help predict and learn from natural processes in the environment and determine human impacts on an ecosystem.

It may be due to eroded soil caused by dredging or due to the growth of micro-organisms. High turbidity makes filtration expensive. If sewage solids are present, pathogens may be encased in the particles and escape the action of chlorine during disinfection.<\/p>\n<!-- \/wp:paragraph --><!-- wp:paragraph -->\n<p><strong>Total Dissolved Solids (TDS) <\/strong>are the total amount of mobile charged ions, including minerals, salts or metals dissolved in a given volume of water.

Common waterborne diseases are intestinal infections, dysentery, hepatitis, typhoid fever, and cholera. Testing water for pathogenic microbes is impractical as disease causing microbes are present in small numbers and they are difficult to be detected. Therefore, Coliform tests are carried out for water. Coliform bacteria are present in the intestines of animals and are released in large numbers with wastes from the body. Presence of Coliform bacteria in water indicates contamination of animal waste and presence of pathogenic micro-organisms and is not suitable for human consumption.\u00a0 Thus, it is important to test water for Coliform bacteria and make sure that there are none.<\/p>\n<!-- \/wp:paragraph --><!-- wp:heading -->\n<h2><span style=\"color: #0068ac;\"><strong>References<\/strong><\/span><\/h2>\n<!-- \/wp:heading --><!-- wp:paragraph -->\n<p>FAO, (1999).
