Water pollution Water pollution is the contamination of water bodies . Mostly water pollution occurs in lakes‚ rivers‚ oceans‚ aquifers and groundwater. Water pollution occurs when pollutants are directly or indirectly discharged into water bodies without adequate treatmentto remove harmful compounds. Type of water pollutions There are many types of water pollution because water comes from many sources. Here are a few types of water pollution: 1. Nutrients Pollution Some wastewater‚ fertilizers

I enjoyed doing the virtual lab. I treat water as an occupation so I understood how and what to add to treat the water. If you have a low (acidic) pH then you should add sodium hydroxide. If you have total coliforms‚ you should chlorinate before and after treatment. Often‚ we test houses for total coliforms and e. coli. If the bacteria is positive‚ then we chlorinate the well. After we make sure all the chlorine is throughout the house‚ we let it sit for 24 hours to disinfect the pipes and

Bohnenberger Professor Van Doorn ENVS 150-002 2 March 2015 Water Quality Lab Report Introduction: When people are asked about how water is characterized‚ they usually will think of saltwater‚ freshwater‚ safe-to-drink freshwater‚ and tap water. Only a few people understand that water and its quality are characterized in several other ways beyond salt‚ fresh‚ and tap water. In 1967‚ the Water Quality Act‚ which was an amendment of the Federal Water Pollution Control Act‚ was passed. The Act required

Nitrate on Pond Water By Claudia Phillips September 6‚ 2014 Block Two INTRODUCTION This lab was designed to study and observe the effects of phosphate and nitrate applied to pond water (1). Phosphorous‚ commonly used in fertilizers‚ is a necessary and vital element for life but can enhance the effects of eutrophication (the over-enrichment of nutrients in water) (2). Nitrate is a common source of food for most algae‚ but too much can make living conditions in water harsh (3). They are

Kaileah Diaz November 10‚2017 Period: 3 Weathering Lab Report Water erosion is usually caused by rainfall and runoff on a slope‚ and the magnitude of water erosion depends on the type of soil. This can occur on river banks‚ seashores‚ streams‚ or even seaside cliffs. Muddy water is also a sign of erosion. There are brown hue results from the suspension of rock and soil particles inside the water. Water erosion usually happens in the springtime because there is usually a lot more rainfall and

This will allow it to absorb some carbon dioxide from the atmosphere and lower its pH from a level of about 7 to about 5.8. The distilled water will act as a model for "normal" rainwater‚ which has a pH of about

The intention of the “Foul Water” lab was to purify a sample of sewage water and conserve as much as possible. The water should be clean enough to wash your hands with. My hypothesis is that the water will be cleaner than the initial water sample‚ but not to the standard that I would wash my hands with. Significant terms to know include purification‚ filtration‚ adsorption‚ volume‚ clarity‚ dissolved‚ filtrate‚ impurities‚ pipette‚ clay triangle‚ funnel cone‚ iron ring‚ beaker‚ and Erlenmeyer flask

Introduction: This lab investigates the question‚ what is the water quality of the U-High creek based on micro invertebrates found in the creek? There are many factors that affect the quality of water such as phosphorus and nitrogen levels‚ dissolved oxygen‚ and pH. Phosphorus and nitrogen in water can increase the growth of aquatic plants and algae‚ leading to the decomposition of dead plant material and the removal of dissolved oxygen from water. The total nitrogen concentrations for freshwater

of purified water again. Due to the people of the United States drinking billions of gallons of water daily‚ the amount of purified water we drink is starting to run out which is causing a problem already. Psychological studies have shown humans still don’t accept water being reused even after knowing the water is purified and perfectly clean. Advocates are still against ultraviolet machines being used to clean and purify water. While some people believe that drinking recycled water is both repulsive

Without water‚ life as we know it would cease. Water is all around us and covers at least 70% of the earth’s surface. Fresh water supply is however not so easy to come by much to the extent that in some areas it lacks completely. One of the ways filter press machine of availing clean water for use is by purifying water. This is done by processing water by chemicals which rid it of dirt‚ harmful bacteria and rust among others. "Hard water" is that which contains mainly magnesium and calcium ions
