Sierra Streams Institute laboratory services include nutrient analysis, bacteria analysis and benthic macroinvertebrate sampling and identification. Duplicate sampling by local and state government laboratories in the course of several collaborative studies has confirmed the validity and consistent reliability of our laboratory data. We also sell copies of our Bug Book, a comprehensive guide to macro invertebrates in the region.
Nutrient Analysis
We analyze our water samples for nutrients including:
- Total Phosphate
- Reactive Phosphate
- Nitrates
- Ammonia
- Iron
Bacteria Testing
We analyze our water quality samples for the following bacteria:
- Total Coliform
- E. Coli
Heavy Metals Analysis
We measure point concentrations of heavy metals such as cadmium, arsenic, and lead in solid materials such as soils. NOTE: this analysis is subject to a briefing by staff regarding variability in soil metals and how to interpret measurements. This service does not provide human health guidelines or data that should be used in applying any health guidelines.
Benthic Macroinvertebrate Identification
We provide Benthic Macroinvertebrate (BMI) sample processing. Samples are identified to family level following SWAMP protocol and appropriate QC proceedures. Additionally, we have published “The Bug Book” that is available for sale below.
