Metals & Nutrients
Determination of metals and nutrient loading requirements in municipal or industrial biosolids satisfies compliance requirements for land application to irrigated or non irrigated sites. We are very familiar with these complex matrices and provide prompt turn around time. We use methods established by EPA, AOAC and APHA.
Microbiology (Pathogen Reduction)
7 discrete samples are required in the CFR 503 regulations to characterize the pathogen reduction compliance in biosolids operations. There are certain times of the year when there is a bit of a rush to meet this requirement. Please call ahead and let us know when your samples will be coming in, so we can make sure to get them set up quickly in accordance with the regulations. For more information, see the Deptartment of Ecology biosolids page linked above.
Biosolids for Beneficial Use
Verifying that biosolids from your facility meet criteria for beneficial use is a specialty of ours. Samples can be shipped or delivered in time to meet the hold time for microbiological analysis and the requirements for nutrients and heavy metals data is reliably delivered. Cascade Analytical offers complete CFR 503 analysis for biosolids. Advance notice is always helpful when dealing with biosolids and their short 6 hour hold time. We always appreciate your cooperation that allows us to serve you well!
