Proper collection and handling of samples are important to ensure an accurate and complete analysis is performed. In addition to these general guidelines, we've provided detailed instructions for collecting microbiology and radiochemistry samples.
The Florida Department of Health has provided these instructions for Initial Water Quality Water Clearance for 64E-8.006 governed water supplies.
Obtain 1 water sample from the source prior to any treatment for bacteriological analysis (Total Coliform). Fill out the "Drinking Water Analysis" form with details of the sampling event. Not all blanks need to be filled out - only what applies to your water supply.
Complete the Bacteriological Analysis form and the 64E-8 Chemical Analysis form. These forms will be included with the sample containers KNL will provide to you.
There are 2 protocols to follow for radiochemical analysis. The protocol you follow will be based on which analyse are being tested.
KNL uses EPA Method 900.0 Rev. 1(equivalent to Std. Methods method 7110B) for measurement of Gross Alpha particle activity in water samples. Although this method is the "standard" for the measurement of Gross Alpha in all types of water, it has its limitations. More specifically, samples with high solids content experience severe alpha self-absorption, leading directly to high detection limits and high 95% confidence level calculations. The EPA Eastern Environmental Radiation Facility has developed an alternative method for Gross Alpha that addresses these limitations, permitting lower detection limits for high-solids samples. This method has full EPA approval (EERF:00-02). Analyses by this method are slightly more expensive than by method 900.0 Rev. 1
If you are interested in having your high-solids samples analyzed using this alternate method, please indicate this on your analysis request documentation.
