Identifying potentially induced seismicity and assessing statistical significance in Oklahoma and California [PDF]
JGR Solid Earth 2017, 2016 We develop a statistical method for identifying induced seismicity from large datasets and apply the method to decades of wastewater disposal and seismicity data in California and Oklahoma. The method is robust against a variety of potential pitfalls. The study regions are divided into gridblocks.

Defining the lead time of wastewater-based epidemiology for COVID-19 [PDF]
arXiv, 2021 Individuals infected with SARS-CoV-2, the virus that causes COVID-19, may shed the virus in stool before developing symptoms, suggesting that measurements of SARS-CoV-2 concentrations in wastewater could be a "leading indicator" of COVID-19 prevalence.

International Journal of Contemporary Research and Review, 2017 Waste water generation is one of the major complex causing water pollution. Water a natural resource is used by different sectors of society for various activities like drinking, diluting wastes, manufacturing goods, food production, energy generation and usage and so on to fulfil national demands. Generation of wastewater is highly unavoidable, in the

Natural pigments from microalgae grown in industrial wastewater [PDF]
Bioresource Technology 303, 122894 (2020), 2020 The aim of this study was to investigate the cultivation of Nostoc sp., Arthrospira platensis and Porphyridium purpureum in industrial wastewater to produce phycobiliproteins. Initially, light intensity and growth medium composition were optimized, indicating that light conditions influenced the phycobiliproteins production more than the medium ...
