" Arranging and tracking sub-lab work is about as fun as watching paint dry. It's refreshing to be able to fax over some permit pages to Hydrosphere and say, 'I need to run this.' The kits come within 48 hours, everything is handled accordingly, and the report shows up with a very clear summary page so there is no guessing as to whether the samples passed or failed."

Toxicity Testing

Hydrosphere Research is a state and nationally recognized aquatic toxicity testing laboratory. We routinely conduct tests to satisfy NPDES permits and characterize toxicity problems. Our clients also call upon us to design new and innovative toxicity studies.

Toxicity Identification Evaluations

Hydrosphere Research conducts Phase I, II, & III Toxicity Identification Evaluations (TIE) for clients throughout Florida. These studies have involved both acute and chronic TIE’s with both freshwater and marine species.

Many times, a full phase I TIE is not required. Hydrosphere Research will consult with you to determine a hierarchy of potentially successful treatments based on your experience with your sample and plant operations. Hydrosphere Research’s experience with your sample can prove indispensable when designing a custom TIE.

Endocrine Disruption Testing

Hydrosphere Research is recognized as one of the first commercial labs in the U.S. to be involved with endocrine disruptor studies using aquatic vertebrates and yeast activity based test methods.

We have developed and implemented a suite of tools for assessing the potential reproductive effects of effluents and pure chemicals to aquatic vertebrates. We emphasize endocrine pathways controlled by estrogens and androgens.

Hydrosphere Research works with some of the industry's top researchers at the University of Florida and elsewhere to develop new assays for the detection of endocrine disruptors. We have completed endocrine disruptor projects in the following areas:

  • Rapid screening for endocrine disruptors
  • Fish pathology and histology
  • Laboratory flow through studies on whole compounds
  • Life cycle studies
  • Field evaluations of endocrine disruptors
