Quality and degree of pollution of groundwater, using PIG from a rural part of Telangana State, India

Abstract

Impacts of geogenic and anthropogenic sources change seriously quality of groundwater. Inferior groundwater quality directly affects the human health, agricultural output and industrial sector. The aim of the present study is to evaluate the groundwater quality for drinking purpose and also to identify the pollutants responsible for variation of chemical quality of groundwater, using pollution index of groundwater (PIG). Groundwater samples collected from a rural part of Telangana State, India, were analyzed for pH, total dissolved solids (TDS), calcium (Ca 2+), magnesium (Mg 2+), sodium (Na +), potassium (K +), bicarbonate (HCO − 3), chloride (Cl −), sulfate (SO 2− 4), nitrate (NO − 3) and fluoride (F −). The groundwater is characterized by Na + and HCO − 3 ions. The values of TDS

An integrated indexical investigation of selected heavy metals in drinking water resources from a coastal plain aquifer in Nigeria

“…In PIG evaluation, an overall chemical quality of groundwater (Ow) greater than 0.1 indicates a contribution of about 10% value of 1.0 of the final PIG, thereby depicting the actual influence of different parameters in the pollution of the groundwater [12,[14][15][16]. In this current study, the Ow of pH and all the heavy metals were below 0.1, except for Cu and Ni in sample 6 ( Table 3).…”

“…The pollution index of groundwater (PIG) was developed by Subba Rao [12] and has been successfully used in researches for the monitoring and assessment of drinking water quality [14][15][16]. The final PIG values express the contributions of all analyzed quality variables of groundwater samples.…”

“…where W p is the weight parameter for each of the water quality variables; R w , relative weight of a parameter; S c , the status of concentration; C, analyzed water quality variables' content in each water sample; D s , the respective water quality standard limit of parameter, as described by NIS [23] and WHO [24]; O w , overall quality of the groundwater sample [12,[14][15][16].…”

“…Such methods which are currently being adopted in water quality assessments include pollution index of groundwater (PIG), synthetic pollution index (SPI), integrated water quality index (IWQI), overall index of pollution (OIP), and hierarchical cluster analysis (HCA). Over time, these quality indexing tools have proven to be very useful in categorizing the water quality of different areas in a simple manner [1,2,6,7,[12][13][14][15][16][17]. These tools reflect the pollution statuses of different sources of drinking water, thereby providing insights for sustainable water management.…”

“…Life cannot be sustained more than few days without water, while an inadequate supply of water may change the pattern of distribution of organisms as well as of human beings. But due to anthropogenic activities, the water necessary for our survival is becoming hazardous every day (Rao et al, 2018).…”
