Data on water quality index development for groundwater quality assessment from Obulavaripalli Mandal, YSR district, A.P India

Data in Brief
M PrasadM Ramakrishna Reddy


Groundwater is a vital resource for most developmental activities. Demand for groundwater is increasing due to paucity of surface water and recurrent failures of monsoons. Increasing demand for groundwater causes water level to decline and water quality to deteriorate. This data article is aimed to investigate the quality of drinking water of Obulavaripalli Mandal YSR district based on water quality Index (WQI). To evaluate WQI in the study area, twenty groundwater samples were collected and different physico-chemical parameters viz., pH, EC, TDS, TH, total alkalinity (TA), calcium (Ca2+), magnesium (Mg2+), chloride (Cl-), sulphate (SO42-) and fluoride (F-) were analyzed. WQI data for groundwater samples indicated that 30% of the samples fall under excellent rating, 40% of the samples fall under good category and another 30% of the groundwater is under poor category. Overall groundwater quality is not suitable for drinking purpose.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule.
