Necessity: A Sustainable Science Podcast

Necessity
1. The state of being required
2. An indispensable thing

Welcome to our page dedicated to the NESSE podcast – Necessity. If you would like to make a podcast for NESSE, either about your own research, your experiences of being an early sustainable scientist or any general topic then please email communications@sustainablescientists.org with your idea. If you would like to present a research question to NESSE members, then email research@sustainablescientists.org. If you would like to read some guidelines at how to get started – then read our blog post Podcasting for Dummies!

1. Research Question – Hybrid Water Treatment Unit in Lusaka, Zambia

Hybrid Water Treatment Unit (Low-Cost Nitrate Removal and Disinfection Unit) in Lusaka, ZambiaPic1

Nitrate and microbial contamination of groundwater in the city of Lusaka, Zambia’s capital has continued to escalate far much beyond the stipulated WHO guidelines and Zambia Standards of 50 mg NO3/l and 0 cfu/100ml. In fact, as high as 250 mgNO3/l and 1000 cfu/100ml of E. coli has been reported in the recent studies undertake. The common sources of nitrate pollution are the poorly designed septic tanks, solid waste dumping site and pit-latrines. Unfortunately, most parts of the city more especially peri-urban areas are using groundwater as their source of drinking water. Microbiological contamination has resulted in increased incidences of water borne diseases (including cholera) in peri-urban areas while nitrate poses danger to children and pregnant mother because of the blue-baby syndrome disease associated with nitrates in new born babies. Hence the need to find a low-cost solution in removing nitrates in groundwater before water can be supplied to communities.

Envaros is calling on NESSE members to collaborate in finding a sustainable solution for the provision of safe clean water to affected communities in Lusaka. If you would like to contribute to this solution, or have an idea at how to get it started then please email Daniel at research@sustainablescientists.org
