Water Pollution Facts, Effects of Water Pollution, Clean Water Act
Clean and plentiful water provides the foundation for prosperous communities. We rely on clean water to survive, yet right now we are heading towards a water crisis. Changing climate patterns are threatening lakes and rivers, and key sources that we tap for drinking water are being overdrawn or tainted with pollution. NRDC experts are helping to secure safe and sufficient water for people and the environment by: Promoting water efficiency strategies to help decrease the amount of water wasted;Protecting our water from pollution by defending the Clean Water Act and advocating for solutions like green infrastructure;Helping prepare cities, counties and states for water-related challenges they will face as a result of climate change; andEnsuring that waterways have enough water to support vibrant aquatic ecosystems. Protecting Clean Water Dirty water is the world's biggest health risk, and continues to threaten both quality of life and public health in the United States.

s National Ocean Service Education: Nonpoint Source Pollution The U.S. Environmental Protection Agency (EPA) defines point source pollution as “any single identifiable source of pollution from which pollutants are discharged, such as a pipe, ditch, ship or factory smokestack” (Hill, 1997). Factories and sewage treatment plants are two common types of point sources. Factories, including oil refineries, pulp and paper mills, and chemical, electronics and automobile manufacturers, typically discharge one or more pollutants in their discharged waters (called effluents). Some factories discharge their effluents directly into a waterbody.

Effects of water pollution 1. Human Health We all drink water that comes from a source: this may be a lake or local river. In countries that have poor screening and purification practices, people often get water-borne disease outbreaks such as cholera and tuberculosis. Every year, there are an estimated 3–5 million cholera cases and 100,000–120,000 deaths due to cholera. (WHO estimates that only 5–10% of cases are officially reported.)

A Little Earth Day Trash Talk By: NOAA Marine Debris Program Staff Let’s kick off this Earth Day celebration, with some “Trash Talk”! The marine debris kind of course. Plastic Pollution in Oceans Environmental Issues > Oceans Main Page > All Oceans Documents The Basics We're treating the oceans like a trash bin: around 80 percent of marine litter originates on land, and most of that is plastic. Plastic that pollutes our oceans and waterways has severe impacts on our environment and our economy. Seabirds, whales, sea turtles and other marine life are eating marine plastic pollution and dying from choking, intestinal blockage and starvation. Chemical Pollution Metals are chemical elements that are typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivity. Metals are toxic if they change the structure and function of proteins and enzymes (GESAMP 2001). Metals found in the ocean that are highly toxic on their own include mercury, cadmium, lead, arsenic, tin, copper, nickel, selenium, and zinc. Mercury, cadmium, and lead can become even more highly toxic in combination with organic compounds. For example, mercury can form neurotoxic compounds such as methylmercury (CH3Hg), when combined with carbon.

Clean Water & Sanitation OIC International’s Clean Water and Sanitation programs aim to make measurable and sustainable improvements in water supply, sanitation, hygiene, and the overall environment in the communities we serve. We recognize that in order to successfully improve health in developing areas, programs must be comprehensive, targeting both the direct and indirect causes of poor health and nutrition. We therefore integrate our water and sanitation projects into our health and nutrition programs, as well as our workforce & enterprise development and food security & agriculture programs. The components of our Clean Water and Sanitation programs are to:

Risks to Oceans There are three main ways that the ocean water quality is at risk. They are: Litter in the oceans Did you know that the litter on land can end up in the oceans? What are the effects of water pollution Effects of water pollution. You will notice in the previous pages that water pollution is very harmful to humans, animals and water life. The effects can be catastrophic, depending on the kind of chemicals, concentrations of the pollutants and where there are polluted. Below, we shall see a summary of the effects of water pollution. (Make sure you see the factsheet page for some very unfortunate incidents of water pollution in recent time)

Mercury poisoning Symptoms typically include sensory impairment (vision, hearing, speech), disturbed sensation and a lack of coordination. The type and degree of symptoms exhibited depend upon the individual toxin, the dose, and the method and duration of exposure. Signs and symptoms[edit] Water pollution: An introduction to causes, effects, solutions by Chris Woodford. Last updated: June 29, 2015. Over two thirds of Earth's surface is covered by water; less than a third is taken up by land. As Earth's population continues to grow, people are putting ever-increasing pressure on the planet's water resources.
