Surface Water

The measurement of trace metals under the Clean Water Act can be extremely difficult as the concentrations necessary to meet water quality criteria can be several orders of magnitude below those achievable by most commercial laboratories.

Although a select few laboratories can now detect lower concentration of trace metals instrumentally, many still do not have the expertise or ability to ensure reliable low-level measurements from sample collection to analysis.

We specifically clean and test sampling equipment (sample bottles, tubing, and field filtration units) to ensure that all equipment used for sample collection will allow for the measurement of trace elements a concentrations required for most surface water criteria. These cleaning and testing procedures are critical to successfully monitoring ambient concentrations of trace metals in surface water and one major component of EPA Method 1669, Sampling Ambient Water for Trace Metals at EPA Water Quality Criteria Levels.
