Physical And Chemical Properties Of Water In El Mansouriya Stream

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.

Codi noticed an irregularity in the river when her biology students and herself tested the pH of the river and found that it was very acidic. The Environmental

The health of the Susquehanna River and Chesapeake Bay was found based on Biological (macroinvertebrates and wildlife) and Chemicals characteristics (pH, dissolved oxygen, phosphates, nitrates, etc.) as well as physical observations (amount of forested buffers, wetlands, etc.) Overall it was concluded that the health of the water was good to excellent. What was found was that many of the macroinvertebrates found in the water were sensitive or facultative, meaning the water quality was good enough for them to live in. Also, the level of ph, temperature, dissolved oxygen, phosphates, nitrates, and turbidity showed that the water quality was good. Finally, while we were canoeing down the Susquehanna River, observations were made on the land

Through our research we aimed to determine if there were any differences in water quality of both the north and south forks of Strawberry Creek. As time progresses and the environment changes it is important to keep track of how certain species are being impacted by these features, and how they cope with change. We hypothesized that due to the lack of pollution, the south fork will promote a greater diversity of macroinvertebrates. This was due to the fact that there was less runoff and trash that could be introduced to the water in the south fork, than there was in the north fork. We gathered data by analyzing the different organisms living in both forks. We collected a total of fifty vials composed of five organisms from each fork, and inspected them under microscopic view. After gathering data and identifying the different kinds of organisms living in the different forks we assessed whether the organisms from the samples could live in high or low resolution water. We also took a t-test to assess the probability of these differences being due to relevant factors or by chance. Our major findings suggest that organisms in the south fork showed a higher demand to living in cleaner water indicating that our hypothesis was correct.

Government agencies carefully monitor water quality and its effect on wetlands (Reference: Environment Protection Agency Wetland Report EPA 832-R-93-005). Of particular concern is the concentration of nitrogen in water draining from fertilized lands. Too much nitrogen can kill fish and wildlife. Twenty-eight samples of water were taken at random from a lake. The nitrogen concentration (milligrams of nitrogen per liter of water) was determined for each sample. The variable in this information is nitrogen concentration (mg nitrogen/l water).

Overall, the more macroinvertebrates in the water, the healthier the stream. pH is a measure of how acidic or basic water is. It is measured on a scale from 0-14. 0 is the most acidic, 14 is the most basic, and 7 is neutral. It is the measure of the relative amount of free hydrogen and hydroxide ions in the water. Acidic water has more hydrogen ions, and basic water has more hydroxide ions. When water’s pH is around neutral (7), that is a suitable and healthy living environment for fish, and indicates a healthy stream. If the water is too acidic or too basic, it can be harmful to the aquatic life. Dissolved oxygen is a measure of how much oxygen is dissolved in the water. As the amount of dissolved oxygen drops below normal levels in water bodies, the water quality is harmed and creatures begin to die off as a result of eutrophication. The higher the level of dissolved oxygen, the healthier the stream. When there is a lot of dissolved oxygen present it makes for a safe environment for fish to live and reproduce. Having all this healthy fish can provide us with food, so overall the more dissolved oxygen, the better. Nitrates are a compound found in fertilizers that is used to help plants grow. It is what is given off as a result of the use of nitrogen in water. The organisms in the soil eat the nitrates and it helps the metabolism and the health of organisms. Plants, such as Algae use nitrates as a source

The first piece of evidence supporting this statement is a water quality index of 48. The 7 pollution sensitive organisms in the creek are worth three points each on the water quality index, plus the 10 moderately tolerant organisms each 2 points and the 7 tolerant organisms each 1 point add up to get the 48 water quality index. The water quality level is considered excellent if it is 23 or above. The water quality in the U-High creek is more than twice that. There were many different types of organisms found in the creek including 7 pollution intolerant micro invertebrates. The total number of organisms including the 88 pollution intolerant Caddis fly larvae point to a low pollution level in the creek. The 10 moderately tolerant micro invertebrates also point to low polluted creek. There were also a high number of midges and aquatic worms. The water in the creek was also very clear and did not have a smell. There were many small fish and plants growing in and around it concluding a low pollution level in the

On October 6th 2015, the students of Mattawan’s AP Environmental class took a trip to the local stream of the Mattawan Consolidated Schools area. The purpose of this trip was to conduct a stream study to determine the health, conditions, and pollution levels of this small body of water. A multitude of factors came into play when making a judgement on the stream’s health, and making sure to take all of these essential points was crucial to the study. A variety of thorough experiments were conducted to help make this overlying conclusion, as many students adopted many roles in the study. Students used a physical survey form, water test data sheet, and taxa recording sheet to record their findings. Teamwork was essential in making sure all of this information could be found accurately and efficiently. The combination of all of the final results allowed the class to make a judgement of the stream’s state.

The first station we had was counting crustaceans and macroinvertebrates in the water. We found 113 critters that belonged in group 1 which means it is quality water. There were 2 organisms in group 2 which was somewhat quality water. Also, 16 critters in group 3 which means the water is very polluted. Overall, based on the critter

In the North Queensland Resource Planning and Development, the consumption of high quality drinking water has become a major issue. Due to the limited supply of fresh water in other states and South East Queensland, a major re-education of the public on water usage has occurred. The demand for water has increased within the Cairns region, so to provide the extra water needed for the Far North community, the government is considering tapping into the Mulgrave Aquifer. On further investigation, it was seen that this process would be quite expensive to go ahead with. A more viable option would be to source the water directly from the Mulgrave River. The purpose of this report is to analyse and discuss the water quality of four locations along the Mulgrave River.

The water quality of the U-High creek is excellent. However, not all creeks, rivers, or bodies of water have excellent water quality. One way humans pollute water is through the fertilization of crops. Farmers use fertilizers on their plants to help them grow. These fertilizers and pesticides can be washed away from the fields when it rains, causing them to end up in rivers. When large amount of fertilizers end up in a river or creek, the amount of nitrate and phosphate in the water increases. The increases of these chemicals affect algae growth since algae uses these substances to grow. A massive amount of algae growth, which is known as eutrophication, causes pollution. When the algae die and break down, the amount of dissolved oxygen in the water decreases. Algae must use dissolved oxygen in order to break down, thus removing large amount of it from the water.

The question researched was, what is the water quality of the U-High creek based on aquatic invertebrates found in the water? The purpose of the lab was to find out the creek’s water quality. Data collection was done by collecting invertebrates in the U-High creek. Data collection was also done by keeping track of the types and numbers of the invertebrates found. The prediction of the creek water quality was fair. The hypothesis was rejected the water quality was excellent. There were many different types of organisms found in the water including, 6 pollution sensitive organism types, these organisms include Caddisfly larva and a Snipe larva. Therefore the water quality is excellent because pollution sensitive organisms were living in the creek. They were able to live because there weren't any pollutants found in the creek . If there were pollutants found in the creek then the pollution sensitive organisms would most likely die first. Based on

Along Cabbage Tree Creek, four different sites were examined by two year 11 Biology classes to discuss how healthy the waterway is as an entire creek. The whole point of this study was to evaluate what the water quality is and what effect it has on the biotic and abiotic factors of the creek. The four different sites were Aspley High behind the oval, Linkfield Drive, Graham Road and Collins Road where the students examined the water and tested the levels of dissolved oxygen, the temperature, turbidity, salinity, pH, flow rate, the amount of phosphate, nitrate and chlorine to make conclusions on the health of the creek as a whole. The Riparian width, habitat and the number of fish were also recorded in order to have an idea of what fish and other organisms live in certain places in the creek. The first place visited in the creek was the site behind Aspley State High School and had the best habitat rating of 17 out of 24. This is because there wasn’t the same amount of litter as the other sites, the creek seemed to have a good flow rate and there was a good amount of instream cover to cool down the creek. The second place in the creek that was visited was Linkfield Drive and out of all four places was deemed to be the unhealthiest with a habitat rating of 11.5.

Water quality data (fixed-interval sample) collected bi-monthly from 1999-2008 and monthly from 2009-2013 for all 18 monitoring sites within the Reedy Fork and Buffalo Creek basins over a 15-year period was obtained from The City of Greensboro Stormwater Division, North Carolina. The sampled data were grouped in ranges of years from 1999-2002, 2003-2008, 2009-2010 and 2011-2013 so as to obtain a detailed analysis on the data. The sampling sites in the study area were numbered for simplicity of result presentation. Sites 1 to 6 were located at the highly sub-urban and agricultural area and sites 7 to 18 were located in the highly urbanized area of Greensboro. This sites include; Bluff Run (1), Fleming (2), Friendship Church Rd (3), Old Oak Ridge Rd. (4), Pleasant Ridge (5) and Battleground Ave. (6), are located in the Reedy Fork Creek basin (Figure 1). Whereas Aycock (7), North Church St. (8), Fieldcrest Dr. (9), McConnell (10), Merritt Dr. (11), 16th St. (12), Randleman Rd (13), Rankin Mills Rd. (14) West JJ (15), White St. (16), Mcleansville (17), and Summit Ave. (18) sites are located in the Buffalo Creek basin. Twelve water quality parameters were selected for statistical analysis (Total suspended solids (TSS, mg/L), total Kjeldahl nitrogen (TKN, m/L), chemical oxygen demand (COD, mg/L), biochemical oxygen demand (BOD5, mg/L), total dissolved solids (TDS, mg/L), total Phosphorus (TPhos, mg/L),Turbidity (TURB, NTU) nitrite nitrogen (NO2-N, mg/L), nitrate nitrogen (NO3-N,

Benthic macroinvertebrates have been used to assess the health of aquatic environments. Quality analysis involves looking at benthic species composition and organization within the stream (Resh and Unzicke 1975). Different macroinvertebrates have differing sensitivities to pollutant, with some being more susceptible to environmental toxins than others (Metcalfe 1989). Such methods group macroinvertebrates in regards to their tolerance to pollution.
