Compliance with the Washington State Department of Agriculture (WSDA) fertilizer regulations requires analysis of heavy metals and nutrients in order to sell in the State of Washington. Our analytical packages provide results that are acceptable to WSDA and we are able to assist you with completion of the fertilizer characterization forms and selection of the analytical package. Please provide an MSDS with order form so that analysts can proceed safely with analysis.

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! biosolids_truck
