A continuous, in-situ, near-time fluorescence sensor coupled with a machine learning model for detection of fecal contamination risk in drinking water

We designed and validated a sensitive, continuous, in-situ, remotely reporting tryptophan-like fluorescence sensor and coupled it with a machine learning model to predict high-risk fecal contamination in water (10 colony forming units (CFU)/100mL E. coli). We characterized the sensor’s response to multiple fluorescence interferents with benchtop analysis. The sensor’s minimum detection limit (MDL) of tryptophan…

Virridy partners with Kenyan government, NASA, USAID, Millennium Water Alliance, CU Boulder to strengthen water security

Millions of people living in the drought prone Horn of Africa face persistent threat from a lack of safe, reliable and affordable water year-round. The arid regions of Kenya are experiencing increasing frequency and severity of drought conditions. Virridy’s satellite connected sensors are monitoring millions of people’s water supplies in the region on a daily…

Virridy to develop soil carbon sensors and models

We are developing an entirely new sensor-based approach to the monitoring of soil carbon changes. The current state of the science, products and market relies on expensive and unreliable field measurements that are difficult to scale and/or modeling approaches that are partially to wholly abstracted from real-world changes in field conditions. Our new soil carbon…

Virridy contracted by the World Bank to partner with WaterAid Nigeria

Recently, IoT technologies have been used to monitor critical infrastructure in remote settings. Prior research has supported active O&M campaigns, quantified groundwater extraction rates, and evaluated service delivery approaches. In this study, continuous data collection was used to examine the operating characteristics of rural water infrastructure. Three research questions motivated this work: (1) What are…

Using in-field data to achieve groundwater sustainability

Groundwater, water held underground in the soil or rock, is one of California’s most precious and contentious resources. Due to California’s climate and long-lasting droughts, roughly 85% of California’s population and much of its $50 billion agriculture industry rely on groundwater, as opposed to surface water, as their main water source. In an attempt to…
