A scientific report of water quality of Sample A and B of 1500 words , should be organised to sections:-
References you should do some statistical analysis of the data by Excel or R
Report should not be more than 1500 words In the Introduction to your report, you should focus on factors that affect the chemical composition of rivers . For the Methods section, the procedural aspects of what you did (e.g., calibration of the flame photometer, drawing the calibration graph, rinsing/drying of the conductivity probe) are standard good practice features of laboratory work, so you do not need to mention these details (you can assume your reader knows about them), but you do need to state what instrumentation was used. So, you used a VWR EC300 conductivity probe and meter, a Corning 410 Flame Photometer for the calcium, and a Merck 1.14661.0001 field testing kit for phosphate.
Introduction The interest in and concern about river water quality is motivated by a number of factors. It has a profound impact on ecological processes and the ecological value of freshwater habitats, and it determines the suitability of stretches of river for designated uses such as fisheries and bathing. Deriving from this, the Environment Agency have a statutory responsibility to monitor inland waters, which includes identifying and responding to pollution incidents. From a global perspective, rivers are also important in biogeochemical cycling, and for many elements river transport from the land surface to the sea is the largest single flux in the global cycle. The principal factors that affect the composition and concentration of chemical constituents in river water are catchment geology and the influence that has on the products of chemical weathering, land-use (particularly agriculture), direct discharges from human activities (e.g., sewage treatment works), biological processes, and the precipitation rate (i.e., how much it rains). Aims In this exercise, you will be analysing two river water samples from contrasting catchments, and, taken together with some additional data provided for these samples, you will be:
identifying where there are statistically significant differences;
deducing some of the characteristics of the catchments (e.g., geology, land-use);
writing up the investigation as a full scientific report. Useful References Library Texts: Hammerton, D. (1996) An Introduction to Water Quality in Rivers, Coastal Waters and Estuaries.
