 Hall Environmental Analysis Laboratory (HEAL) performs analysis on drinking water, wastewater, solid wastes, soils, oils, and air. All samples received at HEAL are entered into the state of the art laboratory information management system. Samples are then distributed to the appropriate section of the laboratory (metals, inorganics, semivolatile organics, and volatile organics). Each of these sections are separated from each other to prevent any type of cross contamination. HEAL is continually striving to meet all of our customers needs. New tests are added every year to keep up with changing markets. Below is a list of standard tests performed by HEAL in-house. HEAL offers many additional tests not listed here. For questions regarding your individual needs, please call our staff.
