Moderately-rapid assessment of alkaline desiccation environmental systems
… lower than the 1000 MPN/g United States Environmental Protection Agency (USEPA) limit. Alkalinity, not pH, was determined to be the limiting factor in some waste samples, resulting in the need to dilute the waste with local soils. Designs were developed to reduce the unnecessarily long …
