Temporal Variation Of Municipal Water Quality

Introduction: The purpose of this research is to determine whether there has been a change in the overall water quality of the Lake Tarpon Basin, and if so, whether the quality has improved or worsened. The variables that will determine whether the quality has changed are: nutrients (phosphates and nitrates) and dissolved oxygen (DO). The expected changes are lower dissolved oxygen levels (from the already low levels), higher nitrogen levels (from the already high nitrogen levels), and the state qualifications still are not met for nutrients and dissolved oxygen (Levy, Flock, Burnes, Myers, Weed, River 2010). This topic relates to environmental management because the changes in water quality would be due to pollution, which relates to the question “How does human activity lead to the pollution of water stores?” The hypothesis that will be tested is that Lake Tarpon’s water quality will have worsened since the last measurements by Levy, Flock, Burnes, Myers, Weed, and Rivera in 2010.

San Diego is a great place to live due to the climate and employment and education opportunities, overall a health conscious city. Areas that need improvement include decreasing the need for food stamps, assisting the homeless in obtaining necessary shelter, improve the drinking water quality, and improve the awareness of the emergency plans amongst San Diego residents. Based on the information San Diego is essentially a lively city in need of a few improvements. The most important issue that needs address is the homeless situation. Being a city with many military bases/agencies, and having the largest number of homeless veterans in the nation, San Diego needs to reach out to these individuals and offer assistance so these folks can get the training needed to be successful in life. Also, drinking water quality must be improved. The governing agencies should implement efforts to address better regulation of water quality. Addressing the increasing number of people requiring food stamps would be a high priority also. Having a well-nourished community will promote good health and is the number one defense against illness. Of minor note is the need to improve the awareness of the emergency preparedness plans present in San Diego County. Planned community will be able to survive any natural disasters.

Descriptive: How has the agricultural industry in America’s Heartland shifted over time? What kind of legislation exists surrounding nonpoint source nutrient loading to the Mississippi, as compared to legislation in other countries such as China and Egypt? How does water quality in the Mississippi River compare with that of similar sized rivers, and how do these different levels of water degradation impact societies?

"If we paid as much for tap water as we do for bottled water, most people would have a monthly water bill of over $9,000." - -Andrew C. Revkin - The New York Times

Experiments were done on the water quality and the contamination of groundwater. First, I observed the effects that different pollutants had on groundwater. I predicted that the experiments with the oil and vinegar would create the most contaminations to the water. When the laundry detergent were mixed with the groundwater, it created a light green color with a pleasant smell. The second water treatment experiment were about filtering techniques to remove contaminants from water. I predicted to drain the water by removing all the contaminants

My lab report was based on how ground water could be affected by contaminants that surround us everyday. “ Access to safe drinking water depends not only on the quality of water at source but also on contamination throughout it's way to the user and practices related to purification and sanitation” ( Mishra, S., & Nandeshwar, S. 2013).I was very surprised that the detergent contaminated the water. I thought that the detergent would stay in the soil but it ended up going through the soil into the water. Which then left the water bubbly and dark. These labs may show that we may need to look into more

In the United States we often take our tap water for granted and we seriously shouldn’t. In 2001 a study called What’s on Tap? was released by the Natural Resources Defense Council (NRDC) , a carefully researched, well-documented, and peer-reviewed study of 19 U.S cities. Alarming results found that pollution and deteriorating out-of-date plumbing are sometimes delivering unsafe drinking water to the population.

All around the world, countries are fighting to keep their drinking water clean. Whether it’s streams, rivers, or lakes, countries have taken great measures to maintain high quality drinking water for both human consumption and animal consumption. Countries must first understand the sources of the polltion, then determine the best methods to eliminate the pollution. Clean drinking water is a valuable resource and a the key to human survival. Plants and animals also depend on water for their growth, so all water must be kept clean. The major contributors to water pollution can be classified in three categories, industrial, agricultural and municipal.

Non-point source pollution is pollution that cannot easily be tracked back to its original source. Since it cannot be easily tracked, like industrial sources, it is very difficult to prevent. Non-point source pollution can be from agricultural fields, cars, construction sites or the dust particles in the rain. (Farrell-Poe 1995) The pollution is usually introduced into the bodies of water through run-offs, rain, melting snow or drainage from ditches. It is often like this because when construction is planned, the affects it might have on the ecosystems around it are rarely thought of.

Body Paragraph #1 - Background: Humans use about 75 gallons of water a day for activities, such as cooking, cleaning, bathing, and laundry. Not only do we use water for our own well-being but we also use water to keep animals that we eat healthy and maintain vehicles that we drive on an everyday basis. Only three percent of the water on earth is suitable for drinking, where two percent of water is found only in glaciers and ice and one percent of the world’s water is accessible and drinkable. The majority of the human body is compromised of water. “An adequate supply of safe drinking water is one of the major prerequisites for a healthy life…(Fawell and Nieuwenhuijsen 2003) The quality of drinking water and possible associated health risks vary throughout the world with some regions showing, for example, high levels of arsenic, fluoride or contamination of drinking water by pathogens, whereas elsewhere these are very low and no problem.”

The next summer olympics is scheduled to be held at Tokyo, Japan in 2020. However, on Wednesday, the water quality tests taken had results for having E. Coli bacteria 20 times higher than the accepted levels that were agreed upon for the venue used for aquatic sports. Tests that were run for 26 days between July and September showed results that the international federation set the water quality standards that could be used for ten days during the Olympics. In fact, the quantity of the E. Coli bacteria were as high as 5, 300 per 10 ml, being above the limit set by the International Swimming Federation which was 1,000 per 10 ml. The E. Coli bacteria came from human and animal waste, and may cause illness or diarrhea. The organizers have

The city of Long Beach has approximately 7 miles of public beaches all through out the city. Due to the mild climate thousands of residents and tourists visit the beaches and bays. The beaches are one of the cities most popular attractions; so this raises the concern of what the water quality is like at the beaches and bays. Roughly every week the Health Department’s Environmental Health Water Quality Monitoring Program collects samples of water and analyzes them to determine the quality of the water. Many different factors effect the water quality in Long Beach, the geographical location of the city, the man made structures, the urban runoff, and the Port of Long Beach. All of these things change and or make the water quality worse in Long Beach but there are ways in which it can be improved.

Water quality is a complex term to evaluate. The health of a water ecosystem depends on so many variables. These parameters are each intertwined and connected. For simplicity there are several mainstream parameters that are used in conjunction with each other to determine the water s quality. These include: alkalinity, ammonia content, carbon dioxide, chlorine, nitrates, dissolved oxygen, phosphates, temperature, and turbidity. The most visible sign of poor water quality is reduced animal populations. Almost all animals will suffer if pollutants are in the water supply. There are several ways to lower pollution levels in water.

Water quality of springs in Lebanon varies from location to another. In this report, the location has been set to be in Western Lebanese Mountains, at 500 m altitude. Based on study done by May A.Massoud (faculty of health and sciences, AUB) on Damour River, which reflects similar circumstances of this report study ,the water quality index(WQI) has been calculated over 10 sampling sites during 5 years (2005-2009) and the results are shown in the following table:

In this changing global world, urban water systems are the most essential, valuable and sensitive part of public infrastructure. Different utilities and municipalities are dealing with this infrastructure with high responsibility for proper management and expansion for present and future generations (2). Rising population, growth in development, climate change all these issues are going to increase the demand of water in the future. According to United Nations Department of Economy And Social Affairs (UNDESA), the global water demand is projected to increase by 55% by 2050(3), and the world will face a 40% global shortfall between forecast demand and available supply by 2030(World Economic Forum,2014).
