Water pollution

large companies of contamination into the water well, that had sicken or lead to death of the residential children. Stated in the Anderson V. WR Grace & Co.case, the plaintiffs’ seek to recover from witnessing the death of the children. Three of the plaintiff had also contacted leukemia from the water, and were either in remission or treatment. The other twenty five plaintiffs that had not contacted leukemia, allege that the exposure of the contaminated water caused the illness and other damage…

The beach has three major parts: beach face, berm and back beach. The area above the water, including the intertidal zone, is known as the beach berm. Beach berm can include vegetation, such as trees, shrubs, or grasses. The most familiar characteristic of a beach berm is its type of sand or rock (Marinebio.net, 2014). Along the backshore, accumulations of wind-blown sand may form sand dunes, and when these are sufficiently stable they become consolidated by a characteristic dune vegetation, for…

During the early nineteenth century Indians in Southeast Texas told the tale of a “Fire King” that lived under a small lake on the site now known as Sour Lake. The waters of the lake released spouts of gas and if lit they would burn a blue color across the top of the water. These flames are most likely what brought about the legend of the “Fire King.” The people of Texas recited this legend long after the Native Americans were removed from the area. The native oral tradition told that the…

The Sea Lamprey is a dangerous and destructive fish for the great lakes ecosystem. This species feeds on a great lake fish and needs to be put under control in order to save fish populations in the great lakes and it needs to be stopped. One of the biggest problems with Sea Lamprey is that “Sea lamprey acts as parasitic and invasive species in each new habitat. It attacks and decreases the population of native fish and disturbs the natural balance of the ecosystem”(Softschools.com). An…

area of Gowrie Creek to the northern boundary of the Toowoomba City is approximately 51 km2. These catchments are very steep and they respond quickly to heavy rainfalls and the water level rise in its waterways. East and West Creeks have been heavily modified with concrete and grass lined channels, on-line detention basins, water features, and drop structures. Impact of Urbanisation: Most of the catchment of Gowrie Creek has been urbanised, for residential and commercial purposes which…

For the Ecology I laboratory, Lake Wheeler was used to collect water samples and determine what organisms were present in each specific lake depth. Lakes have four different zones: littoral, trophogenic, tropholytic, and profundal (the last three zones create the limnetic zone). The littoral zone is the most shallow part of the lake and closest to the shore. It also contains the highest amount of dissolved oxygen and sunlight. The trophogenic and tropholytic zones contain phytoplankton and…

Evaluating overall results compiled by practical investigations, the water sample showed very positive results with very minimal flaws in its purity. Observing the physical properties of the sample it had no turbidity and looked relevantly clear. Data shown here may be inaccurate due to many varied factors in the lab testing. Most of the testing heavily relied on the judgment of the human eye to compare charts colours possibly resulting in human error. A low 5 m/L’s was tested each time when…

Algae, a form of biomass, help lakes, but they do need the right environment with the correct pH and different light conditions in order to aid the lake’s health. Algae use sunlight to make food for themselves and give themselves energy through the process known as photosynthesis by using chlorophyll. They also absorbs carbon dioxide, turning it into energy, which would take place more in the nighttime when it’s dark. In this longer-term experiment, I will be evaluating the sun or lack of sun’s…

The ancestors of the current Gitga’at people used to live in Laxgal’tsap (Old Town) in Kitikiata Inlet, an area on the northwestern side of the Douglas Channel. They lived in this area during the winter months, but used several other camps along the coastline during the warmer months. The Gitga’at had their first encounter with the Europeans in the 1870s. Their relationship remained economical until the arrival of two missionaries: Thomas Crosby and William Duncan. Many of the Gitga’at joined…

The reading material and lecture discuss several theories about ways that agnostids live. The writer presents several theories including free-swimming predators, seafloor dwellers and parasites. However, the professor put forward three reasons that directly contradict the theories and effectively prove that they are not persuadsive and somewhat inaccurate. First of all, the writer suggests that agnostids can swim freely in the ocean. By contrast, in accordance with the professor, this veiw is…
