Where does San Jose, California get its Water?
Introduction
The Earth is a huge planet this is covered by 70 percent water. Astonishingly from this 70 percent the human population can only use 1 percent of the world’s water the rest of it is salt water, frozen, or in some way unattainable (Santa Clara Valley Water District, 2016). Humans have found many different ways to obtain this 1 percent of fresh water they need, but the techniques vary depending on location. In San Jose, California we obtain our water from 3 major sources: groundwater, imported surface water, and local mountain surface water. These 3 sources contribute different amounts of water to the San Jose community. Imported surface water composes about 50 percent of our water supply, while ground water composes roughly 40 percent, and local mountain surface water composes approximately 10 percent (Santa Jose Water Company, 2016). However, these percentages can change due to factors such as weather and global warming.
Groundwater
Groundwater is water that seeps through the ground and gets stored in aquifers. The supply of groundwater is always changing because it is constantly used and replenished. The groundwater supply replenishes and grows due to rain and snow melt and can decrease due to things like droughts and heavy usage. Depending on the type of surface of the ground as much as 20 percent of the rain and snow melt can seep into the ground or as little as 5 percent (Raymond, 1988). Areas where as much as

We all love water, but don’t know much about it. What I mean is that a lot of us don’t even know where our water comes from. That answer varies; for example, the city of Camarillo California gets its’ water in Camrosa Water District. It’s official website, “Camrosa Water District building Water Self- Reliance” provides information like what their purpose is, and as well as water conservation, building self-reliance, and other public information. This website states that Camrosa is currently in a state two water supply shortage. This means that there are restrictions on water use and a call for a voluntary fifteen percent reduction on the amount of water consumption. Also, according to Camrosa “Agricultural Water Management Plan”, water is being
Undoubtedly, Groundwater plays a significant role in California water supply. During a normal year, 30% of the state 's water supply comes from groundwater. In times of extreme drought, groundwater consumption can rise to 60% or more. Even though groundwater is more evenly distributed, over half of the groundwater is unable to be extracted due to the high pumping cost. The largest groundwater reservoirs are found in the Central Valley, with the majority of the supply existing as runoff that seeps into the aquifer.
Water is all around us. This substance is of high importance to every living thing which is on planet earth. As much as we consider water to be life and the most important substance, still we don’t seem to appreciate it very much, as it is being wasted in such great amounts. Everyone believes that water will always be around but not taking into account that the majority of the water on planet earth are not for human consumption. Human beings can only survive on consuming fresh water. The percentage of
From a wider scope of things, water usage is important for more reasons than solely the drought in California. As the world’s population nears 7.4 billion people, more people are born each day compared to how many pass away. Looking at the world’s total volume of water, only 2.5% of it is drinkable fresh water. Furthermore, 70% of that freshwater is frozen. With an every increase population like the one we have today, it is likely that water will become the most important resource to mankind. The problem lies in the way the fresh water is
440). The main way for most aquifers to be recharged is through surface runoff. The rainfall sinks into the ground and percolates or accumulates to a common place (usually an aquifer). Yet this process takes lots of time. Scientists believe it may take centuries to refill some of the deeper aquifers. Water travels especially slow underground. It could take water up to 500 years to travel 15 meters. Aquifers are depended on for roughly 40% of California’s water supply. This number can escalate to 60% during droughts such as the one that just occurred.
Agriculture, probably more than any other human enterprise, is responsible for destabilizing our planet’s water supply. California and their emergency crisis on their low levels of water ultimately having a national controversial impact on the production of the agricultural industry.
For centuries, various civilizations have developed several methods to redirect water from its source to a specified locations. Early Egyptians used a shaduf to lift buckets of water from rivers and as the need to divert water further away from groundwater sources, the more sophisticated the methods became. The Romans built extensive quanats to deliver a fresh water supply while providing a sewage system. Ounce urbanization ensued, the demand for water would require this resource to travel hundreds of miles to reach its destination. Aqueducts, canals, ditches, and dams are all used today to transport water from areas who have an abundance of potable water to areas that lack drinkable water. This was exemplified in the short film “Water on the Edge”. The film addresses the many problems California faces after decades of using various methods for water diversion. Some of the problems include outdated watering systems, maintaining the health of natural systems, and providing water throughout the state while in a drought.
Water sustainability is an ever-growing problem because of the increase in population, and over consumption used by agriculture, industry, and domestic which are using more water than we are able to supply. According to CBS News, California’s water shortage has been a big issue since 2011. Climate change has a lot to do with the amount of water we have available to us because the amount we need does not cut out to the amount needed to satisfy the population. Therefore, conservation is key; we must take into consideration the amount we use in a daily basis. Both you and I can easily save water we have, directly and indirectly like what we consume with what we eat, buy and use, which would overall improve water sustainability.
Over the past 4 years the water crisis has been rearing its mean head not only across the globe, but here in our home country, in the state of California. The citizens in California have moved having a normal lawn of grass into the luxury category. Not only have lakes and rivers dried up, but reservoirs that provide water for the entire state have dropped to hazardous levels. In Calaveras County, home of the state’s fourth largest reservoir, levels of water have dropped to only 20% capacity.
Based on a study more than 17,000 will be losing their jobs, which means their money and we will be losing our fresh food and milk. As a result, groundwater is used for irrigation to grow crops.
Water may be a renewable resource, but the world’s supply of drinkable fresh water is being consumed more rapidly than ever before, and most importantly, more rapidly than it can be replenished. Only 2.5% of water on Earth is fresh
Water covers 70% of our planet, and it is easy to think that it will always be plentiful. However, freshwater, what we drink, bathe in, irrigate our farm fields with makes up only 3% of the world’s water, and two-thirds of that is stored in frozen glaciers or unavailable for our use. Many of the water systems that keep ecosystems thriving and feed a growing human population have become stressed. Rivers, lakes and aquifers are drying up or becoming too polluted to use. Already, 80 countries suffer from water shortages that threaten health and economies while 40 percent of the world—more than 2 billion people—does not have access to clean water or sanitation
Water is the main source of life on the Earth. It is vital for normal existence and functioning of organisms. Earth is sometimes called “water planet.” But, in fact, the number of freshwater is limited. “Only about 2 percent of the planet's water is fresh.” (How much water is there on Earth?) This water is not enough even to meet daily needs of mankind. According to World Health Organization, “a lack of water to meet daily needs is a reality today for one in three people around the world.” (2009) In the Middle East the situation is especially hard. This region is thought to be one of the droughtiest places in the world, most of it’s territory is deserted. Freshwater accounts to 1 percent of the world’s supplies, while the population comes
Groundwater is an important resource in regard to both its quality and quantity. In arid regions where rivers and streams may be less frequent, groundwater represents a sustainable source of water and it is important to determine if specific sites represent a renewable or a minable resource. Groundwater age at a specific site is useful in determining the rate of groundwater recharge or an acceptable rate of water harvesting in order to not completely deplete an aquifer.
