pH is a determined value based on a defined scale. This scale ranges from 1-14. The lower the number is the more acidic the water is, and the higher the number the more basic it is. If water or a substance has a pH of 7, then it is considered neutral. Both, natural and man-made factors can change pH levels in water and other substances. If the pH levels in water are too high or too low, living things in the water will die. pH can also affect the solubility and toxicity of chemicals in the water. (pH of water). Only 2.5 percent of the world’s water is fresh water (Water).
Nitrate is an inorganic compound that can happen under different conditions in the environment. Nitrate has one atom of nitrogen, and three atoms of oxygen. Nitrates

This is mainly for infants (PSEP). Nitrate concentrations are watched in water supplies and foods to make sure that people are not exposed to the potential harmful effects of high levels of nitrates. Nitrates are soluble. For some people, they get their drinking water from wells, which could be contaminated with nitrates. Nitrates are colorless and odorless, so knowing if they’re in the water cannot be determined without the use of special testing equipment. Nitrates can interfere with the ability of people’s red blood cells to carry oxygen. Infants are more at risk of nitrate poisoning than older children or adults. People who use wells for drinking water should monitor the levels of nitrates before drinking it. Infants who drink water that has high nitrate levels may turn a blue color and could have difficulty breathing. This is because their bodies cannot receive enough oxygen. Both, natural causes and human causes can determine the amount of nitrates in water. A body of water could naturally be high in nitrates or have elevated nitrate levels as a result of careless human actions (Menu). Methemoglobinemia is the most significant health problem associated with nitrate in drinking water. Your …show more content…
Phosphorus is needed for plant life, but when there is too much of it in water, it can speed up eutrophication. This is the reduction of dissolved oxygen in water bodies that is caused by an increase of mineral and organic nutrients. This can happen in rivers and lakes. Soil erosion is also a major contributor to phosphorus in streams. Bank erosion that can occur during floods can transport a lot of phosphorous from rivers and close land into streams. Phosphorus gets into water in both urban and agricultural settings. Phosphorus tends to attach to soil, and moves into bodies of water from a runoff. A USGS study showed that phosphorus could also migrate when groundwater flows. Since groundwater often runs into surface water (through streams and rivers) there is a concern about phosphorus concentrations in groundwater affecting the water quality (Phosphorus and
The Eutrophication test determines the amount of nutrients there are in a stream, creek, or most bodies of water. When we did the Eutrophication test we got a lot of low numbers. For the Phosphate test they were mostly a 0 with a .1. When we did the nitrate test we got .25, .75, 1, 1.2, 1.5, 1.3, and a .9. for the dissolved oxygen tests they were all mostly high results.
According to Harrison Eutrophication is the excessive production of algae and higher plants through the enrichment of waters by nitrogen and phosphorus. Phosphorus in the form of phosphate is the limiting nutrient as the amount of biologically available phosphorus is small in relation to the amount needed for algal growth. Harrison states that sources of nutrients can be discrete, (sewage), or diffuse, (farmland fertilizers).
Eutrophication is the excessive nutrients in a lake or body of water, frequently due to runoff from the land, which causes a dense growth of a plant life and death of animal life from lack of oxygen. We tested for phosphate, nitrate, and dissolved oxygen. Phosphates and Nitrates are found in fertilizers, laundry detergents, and sewage treatments. Dissolved oxygen is microscopic bubbles of gaseous oxygen that are mixed in water and aailable to aquatic organisms for respiration. We found that there was a phosphate average of 0.1 parts per million (ppm).
The same is true for the nitrate levels. The location of Commons Stream could be the reason the nitrate level is higher. Commons Stream is near the UMBC parking lot. This in turn has both a heavy student and traffic population. Due to this the nitrates may be contaminated by the excess litter and trash found in the
All organisms need oxygen to survive and when their is not enough oxygen, it leaves plants and animals to die. The area of water where there is a low count of oxygen are often called a dead zones. Also, an increase of the pH level in the water can be created because of algae blooms. The toxic killing algae can make humans sick. For the aquatic animals, these toxins attack mainly the organisms liver and nervous system (Nitrogen and
Nutrient-loading will increase the dissolved oxygen, which high levels will harm aquatic life and affect the water quality. Fish and other species will
Farmers began to grow their crops in San Joaquin Valley for more than 100 years. Farms in the valley produce mostly vegetables, fruits, nuts, and dairy and they are the main manufacturers in international markets and major suppliers in the United States (Hanak & Arnold, 2017). Farmers are using polluted groundwater to grow their crops and harming the environment by drying rivers and causing people to get health problems. The reason that there are pesticides in nitrates in groundwater in San Joaquin Valley may be the fact that there is a long history of farming and irrigation and generally permeable sediments (Burow & Dubrowvsky, 2014). The first organization that noticed the growth of nitrates in groundwater is the Regional Aquifier System Analyses Program.
On page 117 paragraph 4 it says “ Phosphorous is found in fertilizer. In 1986, when detriment levels of phosphorous were discovered, water management becomes primary.” Since the sugarcane crop is grown so close to the Everglades the phosphorous found in fertilizer is getting into the
Oil, grease, and toxic chemicals from human use are also examples of NPS pollution. Bacteria and nutrients from livestock and pet wastes and faulty septic systems are also considered NPS pollution. NPS pollution is a very important issue because it is very damaging to the earth and is the leading cause of water quality problems.
Nitrates should be greater than or equal to one parts per million (ppm), phosphates should be less than or equal to .1 ppm, and the pH values should be about equal to seven. The dissolved oxygen in the river depends on the temperature, if the temperature is cooler than the dissolved oxygen levels will be higher, but the recommended amount of dissolved oxygen should be greater than or equal to five. For a healthy river the turbidity levels should be 120 centimeters
Eutrophication, which is excessive richness of nutrients in any form of body of water, frequently due to runoff from the land, which causes a dense growth of plant life and death of animal life from lack of oxygen, is another reason why the creek could be polluted. Fertilizers are used in farming to provide crops with nutrients, but they also play a big role in the Eutrophication process. If too much fertilizer is used, it leaches from the soil in
Tucson water Tucson, Arizona is a city of 526,116 people and they are all supplied water from the same organization Tucson water. The water has restrictions on what contaminants can be inside the water, but what are the effects of the contaminants which they do not have restrictions on. If they have a mixture of Nitrate-N, Sodium, and Fluoride inside the water then it will cause harm to Caenorhabditis Elegans (C elegans) because the possible large amounts inside the water. C elegans are very similar to humans cellular wise and they are often being used in medical testing and research before moving onto larger subjects.
Drinking water sources have been contaminated with explosive methane, as well as other dangerous substances, such as benzene and arsenic, that can cause cancer and other serious illnesses. Toxic chemicals, as well as erosion and runoff from drilling operations, have fouled
Acids are proton donors in chemical reactions which increase the number of hydrogen ions in a solution while bases are proton acceptors in reactions which reduce the number of hydrogen ions in a solution. Therefore, an acidic solution has more hydrogen ions than a basic solution; and basic solution has more hydroxide ions than an acidic solution. Acid substances taste sour. They have a pH lower than 7 and turns blue litmus paper into red. Meanwhile, bases are slippery and taste bitter.
Strong acids and strong bases are strong electrolytes and are assumed to ionize completely in the presence of water. Weak acids however, only ionize to a limited extend in water. Any weak or strong acids when in contact with any weak or strong alkali will start to undergo neutralization regardless of their volume. When an indicator which is present in the acid-base mixture and have experienced colour change, it indicates that the mixture is in right proportions to neutralize each other and is also known as the equivalence point.
