Dr Louise Weaver (ESR)

Senior scientist Dr Louise Weaver is a member of ESR’s Water, Waste and Social Systems Group. She has been involved on a number of groundwater research projects that support both the Our Land and Water and the New Zealand’s Biological Heritage National Science Challenges. Her groundwater research is focused on identifying how land use, such as farming and waste disposal, affects groundwater quality. Her work frequently assists local councils and communities in developing strategies to reduce or eliminate contaminants in their water systems.

Rupert Craggs (NIWA)

Principal Scientist - Aquatic Pollution

Rupert is a Principal Scientist and Manager of NIWA's Aquatic Pollution Group based in Hamilton, New Zealand. He has specialized in resource (energy, nutrient and water) recovery from wastewater using natural wastewater treatment systems. His research has involved: evaluation, optimisation, design, engineering and construction of ponds, raceways, filters, and scrubbers for wastewater treatment; optimising natural nutrient removal and disinfection processes; and control of midge nuisance and odour release from conventional wastewater treatment ponds. His energy related research has developed Covered Anaerobic Ponds for enhanced biogas production in simple, cost-effective ponds; and wastewater treatment High Rate Algal Ponds with CO2 addition for production of algal biomass for use as fertiliser, feed, or conversion to biofuel. Rupert currently leads two MSI research programmes on energy recovery and biofuel production using enhanced wastewater treatment ponds.
