This charge is for water samples submitted for base water chemistry analysis that require filtration, due to large amounts of suspended silt and clay particules, prior to running the sample.

If this is not paid prior to sample submission and the water sample requires filtration, an additional filtering charge of $15.00 will be invoiced prior to conducting any analysis. This charge is to offset addtional employee labor and filtering costs. If you already know you will incur a filtering charge, please go ahead and add it to your cart.
