The Stewart Environmental Laboratory staff has expertise in chemistry, biology, and microbiology. In addition to our normal routine of compendium analyses, we offer client driven specialty testing and method development. For those situations where EPA methods do not provide what you need, we can tailor analyses to your specific needs. Examples of such methods are phenolic content of phytonutrients, the development of treatment techniques for safe treatment of hazardous waste, and the treatment of wastewater for the removal of manganese.
