SGS is advancing environmental testing innovation with the implementation of Reduced Sample Volume (RSV) methods for water analysis at our Dayton, New Jersey laboratory, effective December 1st, 2025. These changes are applicable as permitted by regulatory program requirements.
This initiative reflects SGS’s ongoing commitment to method development that improves efficiency, reduces environmental impact, and supports compliance with New Jersey Groundwater Quality Standards. Clients will now benefit from smaller sample volumes, reduced from 250mL to as little as 60mL, while maintaining the same high-quality, defensible data that SGS is known for.
Key Advantages of Reduced Sample Volume Technology
Environmental and Safety Benefits
The transition to smaller sample volumes results in a 75% or greater reduction in waste and organic solvent use, with certain methods eliminating dichloromethane (DCM). This significantly reduces solvent exposure for laboratory and field personnel, aligning with our focus on environmental stewardship and workplace safety.
Improved Field Efficiency
Smaller bottles mean less time collecting samples and lighter coolers that are easier to transport and store. This offers substantial savings in time, effort, and field logistics.
Maintained Data Integrity
All RSV methods provide equivalent reporting limits and sensitivities to traditional larger-volume methods and are validated under applicable regulatory programs.
| AQ Analysis | Previous Bottle Size | Reduced Bottle Size | Green Benefits |
| 8082 PCB | 1L (method 3510) | 60ml (method 3511) | completely eliminates DCM |
| 8081 Pest | 1L (method 3510) | 60ml (method 3511) | completely eliminates DCM |
| 608Pest/PCB | 1L (method 3510) | 250ml (method 3510 RVE) | Reduces DCM from 180mls to 45mls = 75% reduction |
| 8270/625 SVOC | 1L (method 3510) | 250ml (method 3510 RVE) | Reduces DCM from 360ml to 90mls = 75% reduction |
| BCTTPH | 1L (method 3510) | 60ml (method 3511) | completely eliminates DCM |
| NJ EPH CAT 1 | 1L (method 3510) | 60ml (method 3511) | completely eliminates DCM |
| 8015 DRO | 1L (method 3510) | 60ml (method 3511) | completely eliminates DCM |
| 8151 HERB | 1L (method 3510) | 250ml (method 3510 RVE) | reduces Ether solvent from 270ml to 70ml = 74.1% reduction |
Implementation and Support
These Reduced Sample Volume methods will become standard at the SGS Dayton, NJ laboratory effective Monday, December 1st, 2025, applicable where regulatory programs allow.
