The document discusses elevated levels of ammonia in drinking water sources in parts of the United States, including Iowa. While ammonia itself is not harmful, its conversion to nitrite and nitrate through nitrification can cause water quality issues. An innovative biological treatment process was developed using a patented aeration contactor design. A pilot study of this process in Palo, Iowa successfully reduced ammonia levels from an average of 3.3 mg/L to nondetectable levels. This led to the construction of a full-scale treatment plant in Palo to document the process. The plant includes monitoring and additions of phosphate to enhance biological activity based on pilot study results.
Water is a unique natural resource among all sources available on earth. It plays an important role in economic development and the general well-being of the country. This study aimed at using the application of water quality index in evaluating the ground water quality innorth-east area of Jaipur in pre and post monsoon for public usage. Total eleven physico–chemical characteristics; total dissolved solids, total hardness,chloride, nitrate, electrical conductance, sodium, fluorideand potassium, pH, turbidity, temperature) were analyzed and observed values were compared with standard values recommended by Indian standard and World Health Organization. Most of parameter show higher value than permissible limit in pre and post monsoon. Water quality index study showed that drinking water in Amer (221.58,277.70), Lalawas (362.74,396.67), Jaisinghpura area (286.00,273.78) were found to be highly contaminated due to high value of total dissolved solids, electrical conductance, total hardness, chloride, nitrate and sodium.Saipura (122.52, 131.00), Naila (120.25, 239.86), Galta (160.9, 204.1) were found to be moderately contaminated for both monsoons. People dependent on this water may prone to health hazard. Therefore some effective measures are urgently required to enhance the quality of water in these areas.

CHARACTERIZATION OF LEACHATE FROM MUNCIPAL LANDFILL AND ITS EFFECT ON SURROUN...Dr. Naveen BP
Percolating water passing through waste becomes contaminated and will have dissolved soluble organic and inorganic compounds as well as suspended particles. Also the pore fluid of the waste is often released and mixes with this water. The entire contaminated fluid is called leachate. There are many factors that affect leachate production like annual precipitation, runoff, infiltration, evaporation, transpiration, and freezing, mean ambient temperature, waste composition, waste density, initial moisture content, and depth of the waste fill. The production of leachate reduces when a landfill is closed. The decomposition of waste in presence of water can be separated into two different phases of degradation viz., initial aerobic and subsequent anaerobic. Generally, the leachate undergoes natural chemical changes over time that reduces its toxicity. Some of the soluble contaminants enrich the water table, or the saturated zone. Some of remaining molecules naturally adsorbed to the clay liner particles. The paper discusses the characteristics of leachate generated from municipal solid waste landfill and its effect on surrounding water bodies near Mavallipura landfill area in Bangalore. Two samples of water from the nearby pond and well were collected from downstream of Mavallipura landfill site. Physico-chemical characterization of leachate has shown that the leachate contains high concentrations of organic and inorganic constituents beyond the permissible limits. While the heavy metals concentration was in traces as the waste is dumped in the landfill is mainly domestic in nature. The pH of the leachate is marginally alkaline as the pH is 7.4. The results also showed that the highest metal concentration that exists in the leachate was Iron which is about of 11.16 ppm. BOD5 and COD of the leachate are 1500 mg/l and 10400 mg/l, respectively. The leachate characteristics indicate favorable growth of algae in natural water contaminated with leachate with the alkaline condition and with the presence of magnesium as nutrient, which has been confirmed in the nearby surface pond. Knowledge of leachate quality will be useful in planning and providing remedial measures to protect surface and ground water quality in the area.

Natural radioactivity in drinking water and associated agedependent dose in L...IOSRJAP
The presence of Ra in drinking water may sometimes make important contribution to natural background radiation exposures. The paper describes the study of 226Ra and 228Ra content in drinking water of Luxor, a famous tourist city in Egypt. A total of thirty-five water samples were analyzed for 226Ra and 228Ra by gamma ray spectrometry with HPGe detector setup, coaxial type and 8192 channels MCA. The concentration of 226Ra was found in the range from 16 to 181 with arithmetic mean 85.6 mBq·L -1 and the concentration of 228Ra ranged from 8 to 98.4 mBq·L -1 with arithmetic mean 48.6 mBq·L -1 .The committed effective dose for the different age groups has been estimated and found to be not more than 0.038 mSv·yr -1 for adults and 0.149 mSv·yr -1 for critical age group (12-17 years old), for 226Ra. While it is not more than 0.05 mSv·yr -1 for adults and 0.29 mSv·yr -1 for critical age group, for 228Ra. The values obtained were compared with the reference values accepted for drinking water and doses resulting from consumption of these waters, due to their 226Ra and 228Ra contents, were calculated. The study showed that 226Ra content for investigated categories of waters is below the levels at which any unacceptable dose due to ingestion would arise
INFLUENCE OF LEACHATE MIGRATION ON GROUND WATER QUALITY Dr. Naveen BP
In this paper, the concept of leachate pollution index, a tool for quantifying the leachate pollution potential and water quality index for surrounding water bodies of Mavallipura landfill site in Bangalore has been applied. It has been found that the leachate generated from the Mavallipura landfill site has high contamination potential to the surrounding water bodies. The results revealed that quality of ground water resources in Mavallipura landfill is deteriorating largely, as a result of the poor practice of solid waste management. Hence, an effective remedial plan needs to be prepared for the sustainable water quality maintenance of the area.

Trace Metals Concentration in Shallow Well Water in Enugu Metropolispaperpublications3
Abstract: This work assesses the concentration of heavy metals in Enugu Municipal well-water considering the fact that some Enugu inhabitants depend on well-water as their major source of water supply. Water from twenty four (24) different hand dug wells from six locations were investigated for Zn, Cu, Pb, Mn, Cd, and Fe using Atomic Absorption Spectroscopy (AAS). The result of the study expressed as the means and standard deviations were compared to WHO and EU standards for drinking water, and it was found that well waters from Iva-Valley and Uwani areas suffer from Cd and Mn pollution. The remaining four locations (Emene, Asata, Abakpa Nike and Achara Layout) were all free from Cd and Mn pollution. Cu, Zn, Fe and Pb concentrations were either completely absent or below world threshold limits at all the locations.
ABSTRACT- A study was carried out to assess the pollution load in river Yamuna at Mathura (U.P.) and its impact on
population size of some aquatic microbes. The key indicators of sewage waste load were Coliform count (MPN), BOD,
sulphates, chloride and ammonia. The susceptible microbes that were analysed included Ulothrix, Paramecium spp.
Difflugia sp. and species of Cyclops. The study revealed that the river is very badly polluted especially with sewage,
garbage and effluents from city and local industries. The population of Coliform bacteria and Ulothrix (algal organisms)
was found very high in those areas, where organic pollutants were very high in amount. But other organisms like,
Paramecium spp. Difflugia spp. and Cyclops exhibited a severe decline in population count, indicating heavy pollution
load, especially during summer months.

Environmental risk assessment of Macabalan creek water in Cagayan de Oro, Phi...Innspub Net
Creek water carries both domestic and commercial wastewater consequently draining organic and inorganic pollutants to coastal water. The present study dealt on the environmental risk assessment of creek water stretching in Macabalan-Cagayan de Oro, Philippines. Selected physicochemical analyses of water samples were carried in both temporal and spatial variations. Risk quotient (RQ), water quality index (WQI), and brine shrimp lethality test (BSL) was employed to draw environmental risk estimate. Overall, dissolved oxygen (DO) concentrations were below the standard set regardless of temporal and spatial variations. Both RQ and WQI showed good statuses on creek water quality despite the low DO. The BSLT similarly indicated a higher concentration for LC50 to be established. The study was preliminary and further monitoring may be essential.

Abstract
This research's main purpose is to analyze the cost incurred for the nitrate contamination in the drinking water. The study focuses on the detail investigation for the health effect because of contact of nitrates in the underground reserves at “San Joaquin Valley”. This report provides detail information about the far-reaching effect of this contamination on the environmental well-being and economic vitality. The major effect of this issue is one of the low-income populations and Spanish oriented residents. San Joaquin Valley is highly contaminated due to the existence of nitrate. It is observed that most of the Californian” always take it forgiven the potable water is easily accessible. San Joaquin Valley has many communicates and agriculture areas. This nitrate contamination has a strong impact on drinking water as well as agriculture land. It is also observed that the drinking water which is served in the homes and schools is also highly contaminated. This contamination has an adverse impact on the overall health of the population in San Joaquin Valley. At the same time, it will also affect the environment along with agriculture. The nitrate contamination is very high as it leads to bring lots of problems for the infants as well as the older population. The focus of this research is to develop the clean water by using the method of cleaning nitrate contamination the results from each method will be analyzed in order to provide the most relevant method. Introduction
My main interest in research is in “Environmental Engineering”. The reason behind the selection of this field is my interest, i want to provide my services in order to make the planet batter. There are many issues faced by the earth which are still not investigated. Water is one of the basic needs of people. But it is also the fact that many people are getting water even for their drinking purpose. A research conducted by Pacific Institute” titled “The Human Costs of Nitrate-Contaminated Drinking Water in San Joaquin Valley” provides several evidences for the nitrate contaminations in the consumable water. Alone in San Joaquin Valley, 63% of the individuals are not getting water for drinking purposes. The groundwater in San Joaquin Valley is extensively contaminated with nitrate. During recent times, most of the world has been subjected to contaminated drinking water. According to the research contrite by Harter that 63% of the water in the valley is not acceptable for the drinking. The water is not usable for drinking purposes as it containsa large amount of “Pesticides, Arsenic, Nitrate, and Uranium”. At the same time, the communities using this water are also facing lots of health issues.
The nitrate has been developed from the nitrogen compound which is excreted from the industries. Nowadays, industrial waste is one of the common issues faced by the environment. As the airborne nitrogen is given off from the industries as well as the automobile it leads to cause l ...

Case Study
Recently, there have been several complaints concerning high levels of lead in American water, specifically in the City of Newark, New Jersey. The residents of Newark City have opted to use bottled water because of the lead contamination in the tapped water. It is so uncommon to find lead at the sources of water, but it gets into water as a result of corrosion of water pipes. The homes that were built in the year 1986 and before have lead fixtures, pipes, and solders. That, however, does not mean that homes that were built afterward don't face the risk of high lead levels in the water they are using. The pipes that are considered lead free have almost eight percent of lead. Lead is a very major hazard in environmental health. Lead is widely used in different commercial products, such as household paint and lead gas. However, lead is very toxic component that affects the ecosystem as well as the human beings living in the ecosystem, especially the young children whose brains are still developing (Schweitze & Nobler, 2018). In the ecosystem, the lead in water can end up in soils because of the corrosion of the leaded pipes. After the soil is corroded, then the plants are highly affected. Lead can as well get into the environment through exhausts of cars. This case study will explore the problems that lead water has in the ecosystem and the possible solutions to those problems.
Disadvantages of Lead Water to the Ecosystem
The first environmental effect of lead water is that the lead gas usually increases the lead concentration in the environment. Lead ends up in the soils and water through the corrosion of the leaded pipes and leaded paints. Lead cannot be broken down, but instead, it is converted into other forms. There are many families in this City that practices fish farming, and they use lead water to carry out the practice. Hence, these water organism faces health problems caused by the presence of lead in the water that they are surviving into. A high level of lead in water is a major problem in the ecosystem as it reduces the number of organisms that survives in the ecosystem specifically, Newark.
Secondly, phytoplankton is usually disturbed when there is interference by lead. Phytoplankton is a very crucial source of oxygen production. This means that lead pollution through water can really affect global balances. Global imbalance brings about problems to the ecosystem (Pieper et, Al., 2018).
The third disadvantage of lead water is the effect that it has on plants. As mentioned in the introduction part, major sources of lead water are the corrosion of the plumbing system. Therefore, there are many places in Newark City that are not rainy. In such places, irrigation is done for farming to take place. When plants absorb lead from the lead water through irrigation, they absorb the lead metal through their leaves. The consumers of planted foods are hu ...
