Coho Water Resources
Integrated Water Resource Management
Geochemistry
Coho’s in-depth understanding of chemistry covers all facets of water resources. We prepare focused analytical plans to minimize cost and maximize the value of the data. We develop lab specifications, secure services, and conduct data validation. We provide Quality Assurance and Quality Control (QA/QC) and prepare Quality Assurance Project Plans (QAPPs). The range of services we cover includes:
Drinking Water:
- Primary standards for human health
- Secondary standards for esthetics (e.g., Fe/Mn)
- System operational considerations (e.g., corrosion control)
- Predictive modeling
- Attenuation rates in the subsurface
- Mixing different source waters (e.g., in distribution systems, or ASR)
- Fingerprinting to identify sources, flow paths, and interactions
- Age-dating (e.g., carbon-14) and ultratrace analysis (e.g., CFCs)
- Micro-Particulate Analysis (MPA) for groundwater under the influence of surface water.
We communicate complex processes clearly for understanding by a variety of audiences.
