Water and cooling water samples should be analysed as soon as possible, preferably within a week, after sampling. Some of the properties/compounds (pH, sulphates and iron for example) of the water may react or precipitate in

All detections of MCHM from the Elk River, from other a ected downstream rivers, and in tap water samples were below levels of concern established by health agencies. The USGS traced the chemicals over 630 kilometers downstream from the spill site.

archive.epa.govWater samples should be collected in the field or prepared in the lab by placing the water in a glass bottle. Typically, a 60-mL serum bottle is used. Add the water down the side of the bottle so as not to agitate the sample. Fill to the top and cap using a butyl rubber Teflon faced septum and the appropriate size aluminum crimp cap.

web.pdx.eduin drinking water supplies is an important public health issue. Atomic emission spectroscopy (AES) is a convenient method for the determination of alkali metals in water samples. These metals are easily excited in flames and consequently can be determined at low concentrations by flame emission.
