This document discusses various types and causes of water pollution. It defines water pollution as the contamination of water sources by substances that make water unusable for human activities. The main types of water pollution are groundwater, surface water, and ocean water pollution. Groundwater pollution can be caused by untreated waste discharge and lead to diseases. Surface water pollution occurs when pollutants are carried by rainwater runoff from urban and agricultural areas. Ocean pollution involves human waste and chemicals affecting the ocean. The document also outlines key pollutants like agriculture, sewage, radioactive materials, and oil spills and their effects on water supplies and human health. Prevention methods include treating industrial waste before discharge and properly disposing of trash.
The Presentation briefly consists about what is water pollution,It's Sources, It's effects, Precautions, etc...
There is also a video about the some examples of the effects of Water Pollution on Humans,Animals and birds.
Water pollution affects plants and organisms living in these bodies of water; and, in almost all cases the effect is damaging either to individual species and populations, but also to the natural biological communities.

Water pollution is an appalling problem, powerful enough to lead the world on a path of destruction. Water is an easy solvent, enabling most pollutants to dissolve in it easily and contaminate it. The most basic effect of water pollution is directly suffered by the organisms and vegetation that survive in water, including amphibians. On a human level, several people die each day due to consumption of polluted and infected water.
Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.
Sachpazis:Terzaghi Bearing Capacity Estimation in simple terms with Calculati...Dr.Costas Sachpazis
Terzaghi's soil bearing capacity theory, developed by Karl Terzaghi, is a fundamental principle in geotechnical engineering used to determine the bearing capacity of shallow foundations. This theory provides a method to calculate the ultimate bearing capacity of soil, which is the maximum load per unit area that the soil can support without undergoing shear failure. The Calculation HTML Code included.

Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.
3. WHAT IS WATER
POLLUTION ?
Water pollution is the contamination of water sources by
substances which make the water unusable for drinking,
cooking, cleaning, swimming, and other activities. Pollutants
include chemicals, trash, bacteria, and parasites. All forms of
pollution eventually make their way to water.

5. GROUND WATER
POLLUTION
Groundwater pollution can be caused by untreated
waste discharge leading to diseases like skin lesions,
bloody diarrhea and dermatitis. This is more common
in locations having limited wastewater treatment
infrastructure, or where there are systematic
failures of the on-site sewage disposal system.

6. SURFACE WATER POLLUTION
Surface water pollution is the pollution of aquatic
systems that are above ground, such as streams,
lakes and rivers. These waters become polluted
when rainwater runoff carries pollutants into the
water. The pollutants transported by runoff are
things like salts and chemicals from city and
highway roads and nutrients and fertilizers from
farms and lawns.
7. OCEAN WATER POLLUTION
Ocean pollution occurs when substances used or spread by humans, such as industrial, agricultural
and residential waste, particles, noise, excess carbon dioxide or invasive organisms enter the ocean
and cause harmful effects there

9. AGRICULTURAL
Agricultural sector is the biggest consumer of global freshwater resources, with farming and livestock
production using about 70 percent of the earth’s surface water supplies, but it’s also a serious water polluter.
Around the world, agriculture is the leading cause of water degradation. Pesticides and fertilizers used in
agriculture can contaminate both groundwater and surface water, as can organic livestock wastes, antibiotics,
silage effluents, and processing wastes from plantation crops.
10. SEWAGE
Contamination of drinking water sources by sewage can
occur from raw sewage overflow, septic tanks, leaking
sewer lines, land application of sludge and partially treated
wastewater. Sewage itself is a complex mixture and can
contain many types of contaminants.
11. RADIOACTIVE
Radioactivity is the phenomenon of spontaneous emission of particles or waves from the unstable nuclei of
some elements. Radioactive contamination is more prevalent in groundwater as compared to surface water
since it is much exposed to radioactive elements found in the rocks. Sometimes, magma also releases
radioactive gases into the environment.
12. OIL SPILL
An oil spill is the release of a liquid petroleum hydrocarbon into the environment, especially the marine
ecosystem, due to human activity, and is a form of pollution. The term is usually given to marine oil spills, where
oil is released into the ocean or coastal waters, but spills may also occur on land.
13. EFFECTS OF WATER
POLLUTION
Human contact with polluted water through drinking, skin
contact or even consumption of food that is grown or
prepared using polluted water poses a significant danger
to health. Pollutants in water may directly cause disease
or act as poisons.
