Drinking Water Reports Samples For Students

Uranium (U) element was discovered by a German chemist, Heinrich Klaproth, in 1789. Uranium is a radioactive element with an atomic weight of 238.02891 and an atomic number of 92. The uranium element initially discovered by Heinrich was an oxide, uranium oxide. A French chemist, Eugène-Melchoir Péligot, was the first person to produce pure uranium by reacting it with potassium in a heated platinum crucible. The element’s radioactive properties were established in 1896 by a French physicist known as Antoine Henri Becquerel. Currently, uranium can be extracted from various ores such as carnotite (K2(UO2)2VO4· ...

Dear Client,

This has reference to your revision request. All the questions (except for one) have been answered. I have made the answers obvious and done and added a few words here and there to make the answers more prominent. Everything is marked in the two pages of the ‘copy of the report’ which follows this letter. Please go through the same and tell me if you still think the paper needs revision, after reading it. In case you want a revision, I’ll be happy to do it for you but you have to tell me what needs to be revised exactly.

Development of the drinking water standards for arsenic since the year 2000

Exposure to Arsenic has become a considerable global environmental health concern as contact through contaminated drinking water leads to cases of several medical conditions and ailments as well as human reproduction and development effects. The source of arsenic in drinking water consists of natural supplies such as rocks, soil and from human activities for instance in preservatives, paints, and agricultural activities. There are increased levels of arsenic in the ground water sources as compared to surface water and this makes people who rely on ground water to be vulnerable to water that is contaminated.
In the U.S. the mean ...

Report on Arsenic-Free Water Filters

Introduction

Arsenic concentration in water varies depending on the source. This report is based on the discussion of the measures of reducing the levels of arsenic in the tube-well water. In this case, three criterions are selected for the study. Each of the methods chosen will enumerate its merits and demerits that suit the application.

Problem

Arsenic is semi-metal element found in the periodic table. It is an odorless, tasteless element that occurs naturally in water, rocks and soils, air, plants and animals.
Arsenic poisoning from various water sources such as well present a significant problem across the globe. The ...

Abstract

Access and availability of portable water supplies in arid and semi-arid areas of the world is quickly becoming a large problem. Notably, these semi-arid and arid regions only have the least amount of annual precipitation and account for 2% of the entire global runoff. Water is and will always be the most important resource in the world. This report will investigate the feasibility of different techniques for providing fresh water in the arid and semi arid regions of Liberia.

Introduction

This is well documented that the chemical composition of water affects the taste, color, odor, and so forth. Some of these salts also pose a threat to human health. The chemical composition of water is based on different dissolved solids. Total dissolved solids are referred to matters in tap water or water bodies that left in a container as residue after evaporation and drying of a water sample. WHO and EPA recommended that it should be below 500 mg/L (Broséus et al., 2009; EPA, 2013).

Classification of Dissolved Solids

The dissolved solids comprised of various salt contents present in the water as well as other ...

NITROGEN AND COPPER DOPED SOLAR LIGHT ACTIVE TIO2 PHOTOCATALYSTS FOR WATER DECONTAMINATION

Abstract:
A new category of photocatalytic coating that can degrade chemical as well as bacterial contaminants under visible sunlight wavelengths was generated by the deposition of a stable photocatalytic TiO2 film over the internal lumen of glass bottles by means of a sol–gel technique. Such a coating was produced either in doped or undoped form. This coating used copper and/ or nitrogen for producing visible light-active TiO2 films that were normalized or annealed at 600 ◦C and were characterized by Raman and X-ray photoelectron spectroscopy. The degradation of methylene blue was seen to accelerate with doped and undoped TiO2 films ...

The term known as "Code of ethics" explains the rules and regulations that are formulated within an organization or team.As per Thomas Edison , "Non-violence leads to the highest ethics, which is the goal of all evolution. Until we stop harming all other living beings, we are still savages.”
The term ethical code encompasses different parameter and may be elaborated as “A guide of principles designed to help professionals conduct business honestly and with integrity. A code of ethics document may outline the mission and values of the business or organization, how professionals are supposed to approach problems, the ...

Abstract

Application of the nanofiltration (NF) and ultrafiltration (UF) processes is applied in the handling of water that is produced raw. The application has been investigated in the current day through various studies (Wang 14). The experiment of the processes of both nanofiltration and ultrafiltration is conducted in the laboratory unit which is operated in a pattern of cross flow (Ashaghi, Ebrahimi, & Czermak, 46). The study that was conducted in Oilfield of North Sea using the process of membranes of ultrafiltration (UF) and microfiltration (MF) indicated that the content of hydrocarbon decreased from 50 mg/l to 2 mg/l which recorded ...

The objective of this experiment was to prepare Beer-Lambert calibration curves for different forms of nitrogen and to determine the concentration of nitrate, nitrite, and ammonia ions in different water samples from the Biscayne Bay.

Introduction

Nitrogen is the most abundant element in the Earth atmosphere. In is not surprising that it is one of the most crucial elements not only to human life but all life on our planet. The chemistry of nitrogen is rather diverse because it can exist in different oxidation levels – from +3 to -5. Due to its large impact on the biosphere, the circulation of ...

In general, Kenya is a dry country; about four-fifths of the land is considered arid or semi-arid. The land considered useful for agriculture only occupies about 17 percent of the nation’s area; throughout the country, average yearly rainfall ranges from 200 mm (in the north) to over 1,800 mm on the sides of Mt. Kenya (The Encyclopedia of Earth, 2008). Ironically, the economy of the country centers around the agricultural part of the country; agricultural products bring in about 30 percent of the nation’s income. When droughts come, they can send Kenya’s economy into severe ...

Carbohydrates play a major role in maintaining and promoting human health: from the provision of energy to maintenance of the microbial composition of the gastrointestinal tract. Some of the functions of carbohydrates in the diet include the following: provision of energy, formation of various body structures, and sparing of other structural proteins from being used to obtain energy.
However, sometimes there is a need to reduce consumption of carbohydrates. For instance, whenever there is a need to reduce weight or to control blood sugar level, people often resort to the use of non-caloric artificial sweeteners. The sweeteners replace glucose in the ...

Introduction

Water is one the most valuable resources in the whole world. For every country to be able to support ecosystem and for a successful socio-economic development, there must exist water. Countries in arid land such as Kuwait find it very difficult to get this most valuable resource and have to go the extra mile to get water (Howard, 2014). The most common method of water provision in Kuwait is through the underground water and desalination process. This paper is set to analyzing the two provision methods to find out what impact they have in terms of cost and how they ...

1.0 Introduction
Water is undoubtedly one of the most abundant elements on our planet. It is present in all areas of the world either as liquid, solid or gas. It does not diminish the fact, however, that fresh water is relatively rare, and its shortage in certain areas may have long-lasting negative economic, social and ecological consequences. Human body may survive without food for up to sixty days, yet absence of water may lead to death from dehydration within 6 days, in certain arid and hot areas – within just 2 days, and lack of peoper drinking water may ...
