Water Analysis to Determine River Tees Chemical Composition

There are many factors that affect the chemical properties of both fresh and sea water, such as pollution, natural occurrences (e.g Algae blooms) and acid rain, and it is imperative that constant monitoring of our water systems is undertaken to be able to act proactively and swiftly to any changes.The pH values of both the fresh water and sea water samples analysed all fell within close proximity to each other and within the parameters of normal surface water of pH>6.5 – pH<8.5, (Environment Agency, 2014) as shown in table 1. .One such example of where water analysis has been instrumental is after the recent floods in the UK where overflow from sewers, rivers and run off from industrial sites has allowed chemicals to enter into wat...

Oedometer Laboratory Testing Report

The soil becomes more tightly packed and there are less voids for water to travel through, thus reducing the permeability of the soil.The aim of this experiment was to investigate the consolidation and swelling process of a sample of clay by using a simple odometer test to gather settlement data and then using it to calculate parameters such as voids ratio, consolidation parameters, constrained modulus, permeability and the consolidation coefficient of the soil.Consolidation occurs due to the generation of an excess pore water pressure.A number of significant relationships between these parameters were identified.* Water was added to the water jacket to prevent drying of the soil sample.

Eutrophication Process Steps

In a given situation, if the primary use or uses of a waterbody is hindered by existing water quality, or else requires water quality or trophic conditions not being met in the waterbody, this signals the need for remedial or control programmes to achieve the necessary in-lake conditions.Obviously, there are water quality conditions to be avoided because of their interference with water uses.Ideally, for example, a lake or reservoir used as a drinking water supply should have water quality as close to an oligotrophy state as possible, since this would insure that only a minimum amount of pre-treatment would be necessary to yield a water suitable for human consumption.Further, in areas with extremely limited water resources, virtually all...
