Field water quality instruments for borehole, safe water and WASH carbon projects — covering the parameters Gold Standard and Verra require for co-benefit evidence.
Water access projects — boreholes, safe water systems and water purification — require baseline and monitoring water quality data. Gold Standard and Verra both require evidence of improved water quality as a co-benefit, and some methodologies require quantified health outcome data. Water quality testing in the field provides evidence that the project's intervention is delivering safe water to beneficiaries.
The field standard for professional water quality measurement. Measures pH, dissolved oxygen, conductivity, turbidity and temperature with laboratory-grade accuracy in a rugged, IP67 field meter. Stores 5,000 data points with GPS coordinates if connected to a compatible device. Probe swap system means one meter covers all parameters. Used by water quality consultants and NGOs worldwide.
Gold Standard's Safe Water Co-benefit requires measured turbidity and microbial contamination data before and after project intervention. The Hach HQ40d covers the physical parameters; pair with a portable incubator for coliform testing.
Specifically designed for drinking water quality assessment in developing world contexts — the exact use case for borehole and safe water carbon projects. Tests faecal coliform, turbidity, pH, chlorine residual and conductivity. Used by WaterAid, UNICEF and MSF in field conditions. Portable case, no power required for most tests, results in 24 hours for microbial testing.
Faecal coliform data is the primary evidence that a borehole or water treatment project is delivering safe water. This is a Gold Standard co-benefit requirement and directly supports the social impact narrative for premium credit pricing.
Extracting a representative water sample from a borehole for quality testing requires a dedicated sampling pump — you can't use a bucket. The MP1 is a lightweight, portable submersible pump for borehole and well sampling. Stainless steel construction prevents sample contamination. Used by hydrogeological consultants for baseline and monitoring sampling.
Borehole water samples must be representative of the aquifer, not the standing water in the casing. A dedicated submersible pump with 3–5 casing volumes purged before sampling is standard practice for defensible water quality data.
