Farmer's slurry in the nearby fields could fall in and pollute the
river. The slurry could cover any vegetation in the river, not
allowing them photosynthesise. Bacteria can reproduce rapidly and can
double once every 20 minutes. The fungi and bacteria can also break
down the plant and they need oxygen to live, so they take it from the
water. This then starves the other animals and plants in the water.
There are two types of sewage: Foul Sewage and Storm sewage. Storm
sewage is the water which washes up anything on the road's surface
such as oil, dog faeces and food. This then goes down the storm
drains. Further down the pipe it will join up with the foul sewage and
if it has been raining heavily it will overflow and go into the river.
Foul sewage is from the toilets and dirty dishwasher water.
If there is a mine near the river, then it can have some bad effects
on the river. If iron is present in the water then the river will look
orange and murky. Iron cannot dissolve in water so the solid covers
the riverbed. This stops the plants from photosynthesising.
Indicators of poor river quality are the animals that live there.
The Afon Llwyd is situated in South Wales. In its lower courses it
joins the river Usk before joining the mouth of the Severn. I decided
to do this topic, as I am curious as to why the river quality varies
along the Afon Llwyd. I expect it will be very interesting to find
out. I did this as part of group.
We looked at four specific sites along the Afon Llwyd. These are some
of the questions that I am hoping to answer.
· How do the aesthetics vary at the different sites?
· How does the oxygen levels vary at the different sites?
· How does the temperature vary at the different sites?
· How does the different species of invertebrates vary at the
different sites?
· How does the pH at the river vary at the different sites?

Most of the rivers are the one being used by large communities like drinking water supply and for the farmers in their produce. The State of Department put together a commission of knowledgeable people and carried out an investigation about the risk and consequences of this project. Some of the conclusion about the spills were, for example, that: “A million of gallons of tar soil war poured into the Kalamazoo River in Michigan… 40 miles of this river still are contaminated to this day”. Another example of spills affecting communities, is the one in 2013, caused by a twenty foot crack in a pipeline, causing a huge spill of oil, damaging the residential neighborhoods and the Lake Conway in Arkansas. This spills and oil “accidents” are affecting not only the lives of people but also the wildlife, the ecosystems and the quality of air and water

Before learning about photosynthesis, I thought this was just a way for plants to grow, not knowing the full detail that goes on inside the plant for it to grow. So, after learning about what photosynthesis is and how it truly works, it is something that is remarkable and how plants are really the only living thing that uses this process. Photosynthesis is the process of taking in carbon dioxide (CO2), which is a gas that is exhaled from animals and goes into the air and is absorbed into a plant, water (H2O) which is absorbed through the roots of a plant or known as capillary action, sunlight is absorbed through chloroplasts which contain chlorophyll or better known as the leaves of the plant. With the photosynthesis process, the plant can create a by-product known as oxygen gas which is released through the little pores into the atmosphere (Simon, Dickey, Hogan & Reece, n.d.).
product and glucose levels. Plants trap the energy in sunlight using chlorophyll, a light trapping pigment found in leaf plant cells. It then uses carbon dioxide which enters the plant through small holes found. on the underside of the leaf called stoma and water which enters the
About 80% of the State’s surveyed freshwater rivers and streams have good water quality that fully supports aquatic life uses, 17% have fair water quality that partially supports aquatic life uses, and 3% have poor water quality that does not support aquatic life uses. Ten percent of the surveyed rivers do not fully support swimming. The major sources of impairment are agriculture (responsible for 53% of the impaired river miles), urban runoff (responsible for 16%), and construction (responsible for 13%). These sources generate siltation, bacteria, and organic wastes that deplete disssolved opxygen.
A river or “stream, ribbons of water confined to channels, or troughs, cut into the land,” (Marshak, 2009) is formed from a drainage network or “the array of interconnecting streams” that form tributaries. (Marshak, 2009). The amount of water that flows down a stream is its discharge. The discharge measurement takes the width and depths or cross sectional area of a river as well as the downstream velocity to get a numeric value for amount of water moving down stream. (Marshak, 2009)
Yet, there is no such thing as “clean hydro power,” with the exception of very small-scale hydropower dams at the individual or neighborhood level. Hydro powered dams can cause major fluctuations in downstream flows, and even dewater the stream channel, leading to direct death of fish and other species. The main effects of a dam on a river is that it disrupts flows, lowers water quality, blocks the movement of rivers vital nutrients and sediment, destroys fish and wildlife habitat, and eliminates recreational opportunities. Reservoirs slow and broaden rivers, making them warmer, reducing water quality, and harboring destructive nonnative species that scatter throughout the watershed and prey on and compete with native wildlife. The environmental, economic, and social impacts of a dam and reservoir may run the entire length of the river from the highest mountain peaks that feed the headwaters to the river’s outlet at the ocean according to
Currently, the Grand River is experiencing problems with toxic chemicals that continue to kill off fish and other underwater wildlife. The majority of these chemicals are released by the Eckert Power Plant located within Moores River Park. Mark Nixon, The Communications Director for The Board of Water and Light, explains that the plant releases enormous amounts of “mercury, sulfur and nitrogen compounds” (15). The Board of Water and Light is working on trying to make the river cleaner in addition to reducing emissions of these harmful chemicals while in the process of moving towards natural gas over coal. An editor for the Physicians of Social Responsibility in the article “Coal Ash” explains that the use of coal is danger...
...hroughout the Eelgrass. Excess water in the form of vapor is disposed of through stomata on the leaves. The gas exchange, root, and shoot systems are used in this exchange because the stomata release the excess water in the form of water vapor, which was first absorbed by the roots in the root system, then transported through the xylem in the shoot system throughout the eelgrass. Another exchange that goes on in Eelgrass is nutrients to plant cells. Again the gas exchange, root, and shoot systems are used. Nutrients are absorbed by the roots and made through photosynthesis; stomata take in carbon dioxide which is used along with light, water, and other nutrients previously stored to make more. Nutrients are carried throughout the plant to plant cells by the phloem. Homeostasis is the balance of systems in organisms and it’s very important to keep them in balance.
Today's waters are constantly being treated like sewage dumps or trash cans. We use them as garbage cans every day polluting the water more and more. "Pollution is often by way of rivers, drains and outflow pipes." Causing an outflow of sewage into our ocean waters. This is not only affecting the community but also the marine life and other sea creatures living in the ocean." This pollution includes human sewage and domestic waste water, factory outflows of acids and poisonous metals, engine oil from roadside drains and garages, farm chemicals washed off the land by rain, building-site rubble, nuclear waste from power plants, and oil from wells, refineries, and tankers." Stating that most of today's waste is from factory or factory ran products that shouldn't be polluting the water
There are many types of pollution. The main types of pollution are water, air, soil, thermal, radioactive, noise, and light. The topic for this experiment is Water Pollution. Water Pollution became a problem in the 1900’s when water started being treated like sewage. Earth Day was founded by United States Senator Gaylord Nelson on April 22, 1970 because of 1900’s pollution. Water Pollution also affects humans and animals. There was a Cholera outbreak in 1854, before water pollution became a problem, and a Typhoid outbreak in New York from 1900 to 1915. There are multiple possible causes to Water Pollution. Humans let out chemicals into the environment, and when some of those chemicals
