Foundry Waste Characterization


Davy Laboratories provides waste characterization for all types of foundry sand, slag, and ash. Detection levels are maintained to insure compliance with Parts B and C of the related DNR codes. All material sampling, bulk chemical analysis, and elutriate samples analyses are conducted using approved methods as found in EPA SW-846. Davy Laboratories uses methods that are appropriate to meet or exceed the required method detection levels.

To ensure sample integrity, we provide sampling instructions and guidance on how to obtain a representative sample. We use all of the collected samples and partition them so that a representative, homogeneous sample is obtained prior to analysis. The results reported are representative of the sample(s) received.

Classification as to whether or not a waste is hazardous is very important, primarily due to the cost of disposal. For example, it is much more cost-effective to send a non-hazardous waste to a local landfill, rather than an improperly-classified hazardous waste to a specialized landfill.

We provide services (as required) for bulk chemical analysis, leachability of the waste (leachate analysis), and physical characteristics of the waste analysis.
