Water sampling
Water is essential for life, but for many people the quality of water available may be poor. Analysis of a water supply may be required to find out whether the water is safe to drink or whether it needs to be treated before consumption. Methods of analysing the quality of water are discussed in other films in this series. It is just as important, however, to ensure that the samples of water tested are representative of the water supply as a whole. Water sampling is therefore as important an activity as the process of water analysis and is the subject of this film.

Membrane filtration to test for faecal contamination of water samples
Thermotolerant faecal coliforms are indicator bacteria, which can form colonies at 44 degrees centigrade and can provide evidence of faecal contamination of water. Membrane filtration is a means of testing the quality of water. This film presents an overview of the process. Water is filtered though a membrane having pore sizes smaller than the size of a bacterium. As water is filtered, bacteria are collected on the surface of the membrane. The bacteria can then be incubated to produce visible colonies suitable for analysis.

ASBC Microbiological Control 1a: Aseptic sampling of beer in process
The American Society of Brewing Chemists (ASBC) and Brewers Association (BA) are collaborating to produce a series of videos that demonstrate fundamental methods related to brewing microbiology. Aseptic sampling technique is an essential skill for attaining a sample from a tank or process point that is representative of the beer or wort to be evaluated. This video demonstrates the ASBC Methods of Analysis aseptic sampling technique, applied to wort stability testing.

A water sample is treated with a solution capable to do a coupling reaction due to the nitrites content. The pink or red color resulted after the diazotization reaction suggests the presence of the nitrites in the sample. This color is analyzed with a spectrophotometer, the results being given in ppm.

Analysis of lysimeter water samples from my tankage research project
For my masters degree research project at the University of Hawaii at Manoa I'm examining tankage, a locally made organic fertilizer, on corn. Corn was selected because it shows good response to nitrogen fertilizers so we can easily see results. We are applying tankage at 5 different rates 0, 100, 200, 300 and 400 lbs/N per acre to see the optimal application rate. In this video I am measuring nitrogen leachate, or runoff, that has been collected in lysimeters installed in the field. Lysimeters collect soil water which I can analyze with the use of a Nitrate and Ammonium selective electrode. Other data collected from the water samples is pH and EC.

Drilling for soil samples
Before a structure or building can be constructed, geotechnical engineers conduct environmental site assessments on the land where the construction will take place. These assessments include soil tests in the areas proposed for development. The engineers examine soil samples to learn about the underground composition of the soils in the area, and make predictions about the long-term effects the soil at the site might have on the walls, foundation, septic system or any other components of the proposed structure. Some soils, such as clays, have a tendency to shrink and swell when their water content changes. This expansive property can put pressure on structure and foundation walls and cause them damage. Other soils are poor at settling or sinking under weight, causing uneven ground. Foundations that are built on these soils are at risk for cracking or bending.
