Water pollution is the contamination of water bodies, very often by human activities. Water can be polluted by various ways; Industry and agriculture are the main source of water pollution. At present polluted water cause very harmful effect to the environment. However, treatment of water reduces some portion of this harmful effect, but this might involve high cost. As a results many industries in our country does not abide by the rules of Government environmental policy and through their waste water into the river. The discharge of wastewater into the environment poses a serious threat. This results environment pollution and causes harmful effect on animal lived in water (e.g. fish) as well as for human beings. But it is also a huge opportunity for ecological health, social wellbeing and green employment. If, high value product is obtained from this polluted industrial waste water, then it might be used by the Industries and environment will be less toxic. These studies show some useful application of industrial waste water to get high value products and services.

4. Biological pollutants such as bacteria, viruses, parasites, and algae.
Heavy metals and toxic compounds from industrial waste pollute nearby water bodies, harming aquatic life and disrupting food chains. Microbial pollutants from sewage cause infectious diseases in aquatic and terrestrial life. Excess nutrients from sewage and fertilizer runoff lead to algal blooms that deplete oxygen and suffocate fish. Atmospheric deposition and global warming raise water temperatures, damaging marine habitats. Case studies on bottled water in India found pesticide residues from contaminated groundwater sources, and oil spills from tanker accidents cause long-lasting damage by coating and killing wildlife.
testing of soil and varoius pollutant in water (punjab)surajdeepa
The document summarizes the current status of a student project testing soil and studying groundwater pollutants. It describes how the students determined the pH, organic matter, available phosphorus, and electrical conductivity of samples from two locations. The results found the pH of both samples to be alkaline, low levels of organic carbon and salt, and medium available phosphorus. The next objectives of the project are outlined, which include determining additional soil properties and studying water pollutants.
Water pollution is any change in water quality that harms living organisms or makes water unsuitable for use. It causes over 14,000 daily deaths worldwide. Pollution can come from natural sources like volcanoes or human sources like factories and cities. Increased nutrients cause eutrophication and hypoxia, reducing oxygen levels and harming marine life. Many pollutants accumulate up the food chain. Water quality is measured through tests of bacteria, oxygen levels, and chemical concentrations. Proper management is needed to address this global public health and environmental issue.

A forest ecosystem is a terrestrial unit consisting of interacting living organisms and their environment. Forests occupy 40% of the world's land area and provide many resources, but face problems. Deforestation worsens global warming by reducing carbon absorption. It also impacts ecosystems, water, soils, plants, and wildlife. Tropical rainforests contain half the world's species, so their destruction causes massive biodiversity loss and extinction. Solutions include corporate anti-deforestation policies, government reforestation and policy support for conservation, and individual choices to recycle and buy recycled products.

The document provides an overview of various types of water pollution including pathogens, organic waste, chemical pollutants, sediments, and nutrients. It discusses key topics like eutrophication, anoxic waters known as "dead zones", sewage treatment, and important acts like the Clean Water Act. The hydrologic cycle and watershed concepts are important frameworks for understanding how pollution spreads through the environment. Organic waste from sources like factory farming can deplete oxygen in water and spread pathogens. Excess nutrients can cause algal blooms and eutrophication.
This document discusses various types of water pollution including their sources, environmental and health effects. It begins by asking overview questions about what pollutes water, major pollution problems in streams/lakes/oceans, and how pollution can be prevented or reduced. It then defines different pollutants such as sediments, sewage, disease-causing agents, and discusses their causes and effects. The document also covers eutrophication, pollution of streams, and figures related to dissolved oxygen levels.
The document outlines Indian drinking water quality standards that specify permissible limits of various chemical and microbiological parameters in drinking water. It provides desirable and permissible limits according to IS 10500 for parameters like pH, turbidity, iron, arsenic, lead, total coliform and E.coli. It also describes potential health risks of exceeding limits for each parameter such as gastrointestinal illnesses, neurological effects, and cancer. Sources of contamination and recommended treatment methods to reduce the parameters are mentioned.
This document discusses India's environmental impact assessment (EIA) process. It provides an overview of the key stages of EIA including screening, scoping, preparation of the EIA report, public consultation, appraisal, and decision making. It notes that EIA was made mandatory in 1994 under environmental protection laws. However, it also outlines several loopholes and deficiencies in the current EIA process, including limited public participation and transparency at certain stages, exemptions that allow projects to bypass EIA, and tight timelines that limit thorough assessments. Overall, the document analyzes India's EIA procedure while pointing out weaknesses that could be addressed to strengthen environmental review and public involvement.
endemic freshwater fishes in the philippinescmsavanag4399
The dwarf pygmy gobi is one of the smallest fish in the world, with mature males reaching only 1.1cm and females 1.5cm on average. The Manila sea catfish is a species of marine catfish found in Luzon, Philippines that was first described in 1840 by French zoologist Achille Valenciennes. By the 1990s, the sinarapan fish was overfished and nearing extinction in its native Philippines, though conservation efforts helped some populations recover through transfers to safer lakes.

Water is uniquely vulnerable to pollution. Known as a “universal solvent,” water is able to dissolve more substances than any other liquid on earth. It’s the reason we have Kool-Aid and brilliant blue waterfalls. It’s also why water is so easily polluted. Toxic substances from farms, towns, and factories readily dissolve into and mix with it, causing water pollution.

The effects of water pollution are outlined as harm to aquatic life and ecosystems. Solutions discussed include environmental laws, education, and preventative measures individuals can take to reduce water pollution.
Water pollution comes from a variety of sources and takes many forms. Major categories of water pollutants include infectious agents from human and animal waste, oxygen-demanding waste from sewage and industry, inorganic chemicals from various sources, plant nutrients from fertilizers, and organic chemicals from industry and households. Groundwater pollution can persist due to slow flows and lack of dilution. Lakes are also vulnerable as pollution is less diluted and stratification hinders dispersal. Ocean pollution results from land runoff and dumping and can damage ecosystems and economies, though some pollutants will degrade and dilute in the oceans.
The document discusses water pollution from the textile industry. It notes that textile production requires large amounts of water, especially for wet processing like dyeing and printing. This wastewater contains various pollutants like dyes, chemicals, and suspended solids. If discharged untreated, it can harm the environment and human health. The document then examines the specific processes that generate different types of wastewater and the pollutants they contain. It also discusses effluent treatment plants (ETPs) that use various biological, chemical, and physical processes to treat wastewater before discharge or reuse. Properly designed ETPs can reduce pollutants to meet regulatory standards, though complete color removal remains a challenge.
Water and noise pollution pose threats to human and environmental health. Water pollution occurs when harmful substances are directly or indirectly discharged into bodies of water. It has various sources like industrial and agricultural runoff. This causes issues like algal blooms and eutrophication that deplete oxygen and endanger aquatic life. Noise pollution is unwanted sound that disturbs humans and wildlife. Major sources are transportation, construction, and industrial activities. Both can negatively impact health, concentration, and hearing if not properly controlled through laws, public awareness, and green infrastructure.
The document discusses different types of pollution including air, water, noise, and their causes and effects. It defines air pollution as the presence of unwanted particles and gases in the air that can harm humans, plants, and structures. Various air pollutants are classified based on their origin, state of matter, and presence indoors or outdoors. Water pollution occurs when contaminants are discharged into water bodies, harming aquatic life and humans. Noise pollution refers to unwanted sound that disrupts daily life and can impact physical and mental health. Solutions to different types of pollution include reducing waste, proper city planning, and increasing awareness.
Water is essential for life on Earth and covers 70% of the planet's surface. It is used for agriculture, drinking, cooking, and industrial purposes.

• These physical pollutants interfere mainly with
the usability and/or aesthetic appeal of the
water. In certain cases, thermal pollution can kill
fish.
17. Making earth little softer
Water pollutants
• Industrial Effluents - This waste water may
contain acids, alkalis, salts, poisons, oils and in
some cases harmful bacteria.
• Mining and Agricultural Wastes Mines,
especially gold and coal mines, are responsible
for large quantities of acid water.
• Agricultural pesticides, fertilizers and herbicides
may wash into rivers and stagnant water bodies.
• Sewage Disposal and Domestic Wastes
Sewage as well as domestic and farm wastes
were often allowed to pollute rivers and dams.
18. Making earth little softer
Pollutants : Unsewered Towns
• Wastewaters and pollutants from unsewered
Towns
• 22% of wastewater (Class I cities) and 14% of
wastewater (Class II cities) is collected through
sewerage.
• Most cities / towns do not have sewerage
system.
19. Making earth little softer
Pollutant – Sewage & sullage

(mercury as a fungicide; lead used in batteries),
Hydrocarbons & Chromium, in rivers and seas
• The metal oxides and other products of the
pharmaceutical industry.
• Hydrocarbons toxic (used to make insecticides -
DDT or processing of plastics and paints)
22. Making earth little softer
Pollutants : Industrial
• Industrial pollutants from large industries
• Installed Treatment and disposal
• Treated effluents having some pollutants get
leached and causes pollution.
• Waste dumping, ash-ponds, sludge-pits, etc.
23. Making earth little softer
Water pollutants
• Major water pollutants :
• Pesticides and biocides like BHC, DDT,
Alluminium phosphide, chlor benzilate, lindane,
nicotine sulphate which are highly pollutant so
such pesticide are restricted in India.
24. Making earth little softer
Water pollutants
• Cadmium and its compounds are used in
various industry they are cadmium acetate,
cadmium sulphide, cadmium oxide, cadmium
carbonate etc.
• The sulphate, chloride and acetate of cadmium
are soluble in water which leads toxicity.
• Floride is universally present in varing amount in
soil and water atmosphere, vegetation and
animal tissue.
• Toxic substance like cyanide, phenol, heavy
metals like mercury, lead, arsenic cause
damage to flora and fauna
25. Making earth little softer
Water pollutants-Heavy metal
• They are present in all the phase of
environment-air, water and land
• Metal pollutant is include copper, lead, zinc,
chromium, nickel, cadmium, mercury and
selenium.
• Lead is one of the heavy metal pollutant of both
atmosphere and ocean, which is mainly derived
from vehicle burning fuel.
• Mercury is the another very toxic pollutant
26. Making earth little softer
Water pollutants
• These pollutants enter waterways through
untreated sewage, storm drains, septic tanks,
runoff from farms, and particularly boats that
dump sewage.
• Though microscopic, these pollutants have a
tremendous effect evidenced by their ability to
cause sickness.
27. Making earth little softer
Water pollutants : Detergents
• Stories about particular pollutant forms:
Detergents
• The nitrates in fertilizers promote excessive
growth of algae and larger aquatic plants,
causing offensive algae blooms and driving out
sport fish.
• Phosphates are often thought to culprit, nitrogen
is the “limiting factor” in most aquatic systems.
28. Making earth little softer
Pollutant : Thermal pollution
• 26% of all water in U.S. is affected by this
• Up to a point of adding heated water, you can
get thermal enrichment
Adding more heat, You get
• Thermal pollution
29. Making earth little softer
Non-persistent (degradable)
• These compounds can be broken down by
chemical reactions or by natural bacteria into
simple, non-polluting substances such as
carbon dioxide and nitrogen.
• if the pollution load is high, this process can
lead to low oxygen levels and eutrophication.
• This damage is reversible.
30. Making earth little softer
Persistent Water pollutants
• Some pesticides (e.g., DDT, dieldrin)
• Some leachate components from landfill sites
(municipal, industrial)
• Petroleum and petroleum products
• PCBs, dioxins, polyaromatic hydrocarbons
(PAHs)
• Radioactive materials such as strontium-90,
cesium-137, radium-226, and uranium
• Metals such as lead, mercury, cadmium
31. Making earth little softer
Persistent Water pollutants
• This is the most rapidly growing type of pollution
• This includes substances that degrade very
slowly or cannot be broken down at all;
• They may remain in the aquatic environment
for years or longer periods of time.
• The damage they cause is either irreversible or
repairable only over decades or centuries
32. Making earth little softer
Pollutant : Detergents
• The nitrates in fertilizers promote excessive
growth of algae and larger aquatic plants,
causing offensive algae blooms and driving out
sport fish.
• Phosphates are often thought to culprit, nitrogen
is the “limiting factor” in most aquatic systems.
33. Making earth little softer
Pollutant : Sediments
• The largest form of water pollution
• Erosion is source – we’ve sped up rate of
erosion, e.g. during urban construction can lose
up to 43 tons of topsoil/acre/year
• Natural rates of erosion: leads to aquatic
succession
34. Making earth little softer
Organic Pollutants
• Three classes of compounds
• Pesticides and Herbicides
• Materials for common household and industrial
use
• Materials for industrial use
35. Making earth little softer
Inorganic Pollutants
• Examples:
• Pb in gasoline
• Radionuclides
• Phosphorus, nitrogen (Great Lakes)
• Other heavy metals
36. Making earth little softer
Inorganic Pollutants
• 3 groups
• 1) Produce no heavlth effects until a threshold
concentration is exceeded—e.g., NO3 –ook at ,
50mg/liter; at higher levels:
methaemoglobinaemia
• 2) No threshold—e.g.—genotoxic substances:
some natural and synthetic organic compounds,
microorganic compunds, some pesticides,
arsenic
• 3) Essential to diets: F, I, Se—absence causes
problems, but too much also causes problems
37. Making earth little softer
Inorganic trace contaminants
• Mercury—methyl Hg and dimethyl Hg in fish—
probably most significant path to humans—
Minamata Bay, Japan, 1950’s
• Rhine River drains 185,000 sq km—heavily
polluted by 1970’s

oxygen depletion, Lake Erie…1972 phosphate
management plant…$7.6 billion
• Nitrates—sewage and fertilizers
40. Making earth little softer
Pesticides
• Pesticides are one of the most significant
causes of water pollution.
• Farmers spraying large crop fields with chemical
pesticides

apply to their home lawns results in a higher
pollution per square foot than the farms
• In-ability to remove specific pesticide
contaminants in the water purification process
41. Making earth little softer

than those used in 1050’s
• About 25% of pesticide use in US is in houses,
gardens, lawns, parks, swimming pools, and
golf courses

Editor's Notes
Pesticides are one of the most significant causes of water pollution. Many think this only applies to farmers whom spray large crop fields with chemical pesticides. The reality is, the lawn products that everyday suburban residents apply to their home lawns results in a higher pollution per square foot than the farms. In some regions, the ability to remove specific pesticide contaminants in the water purification process is an investment that can cost hundreds of millions of dollars per year.
