Water Quality Equipment

Water quality testing for carbon project monitoring

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.

Top Pick
Tap-Fed Treatment Setups
BRITA ON TAP Pro

A practical, directly purchasable Amazon option for teams prototyping household point-of-use water treatment or demonstrating tap-fed filtration workflows. It is not a replacement for full lab testing equipment, but it is a useful piece of client-facing hardware when showcasing low-friction household water treatment options.

For early demonstrations, pilot homes, or community engagement work, a visible treatment device can be more useful than abstract spec sheets alone. It helps bridge the gap between project concept and end-user experience.

Drinking Water Field Testing
DelAgua Field Testing Kit

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.

Borehole Sampling
Portable Water Filtration
Alpkit Hippo Filter Kit Mini

A lightweight portable filter kit for field teams needing safer water access while travelling to remote sites. This is not a borehole sampling pump, but it is useful operational kit for teams working away from trusted treated water sources and wanting a simple personal water-treatment option in the field.

Portable water filter1L per minute flow3,000L lifespanLightweightNo power needed

Field operations are smoother when teams can stay mobile without depending on bottled water or ad hoc local arrangements. A compact filter kit is a simple operational upgrade for remote surveys and longer field days.

Common questions

What water quality parameters does Gold Standard require for water projects?
Gold Standard's Safe and Clean Cooking and Water Access indicators typically require turbidity (<1 NTU for safe water), faecal coliform (0 CFU/100ml for safe water) and pH (6.5–8.5). Some methodologies also require conductivity and arsenic testing depending on the aquifer type. Check the specific version of your methodology and the relevant SDG indicators.
How often do borehole water quality tests need repeating?
Baseline testing is required before project registration. Monitoring frequency varies by methodology — typically annually for the first few years, moving to every 2–3 years once stable baseline is established. More frequent testing may be required after maintenance or any reported water quality issues.
Can I send samples to a local lab instead of testing in the field?
Yes, and for some parameters (arsenic, nitrates, heavy metals) laboratory analysis is required regardless. Field testing covers the parameters needed for initial triage and routine monitoring. Always document chain of custody for samples sent to a laboratory — date, time, sample ID, person responsible, storage conditions.
