Abstract: Groundwater is one of the earth’s most widely distributed and most important natural resources. Groundwater exists, wherever water penetrates beneath the surface. The rocks beneath the surface are permeable enough to transmit water, and at places, the rate of infiltration is so sufficient that the rocks are saturated to an appreciable thickness. This water may be fresh or brackish in quality. As the fresh water constitutes very little quantity of the total water available, we must think as to how best we can exploit it, and utilize it. With the growth of population, today in many of the places water has become a critical source. In many places it is dwindling both in quality and quantity, creating problems for the communities involved. Water Quality Index indicates the quality of drinking water by assessing physical, chemical and biological parameters of water. India had the most studies, with 177 articles, followed by China, Brazil and the United States. This four countries together published 57% of studies on WQI. Groundwater quality implies the level of concentration of different constituents of water which is ultimately described if it is suitable or not for drinking or other purpose such as irrigation. There are mainly three types of constituents or parameters for describing quality of groundwater as physiological, chemical and biological parameters. These parameters are described below: EC ,TDS, K, Na, Ca ,Mg ,TH, Co3, HCO3, Cl, SO4 ,and also we determine some trace element such as Copper (Cu) ,Lead (Pb), Manganese (Mn) ,Nickel (Ni) ,Iron (Fe), Zinc (Zn).

The quality of ground water for drinking water needs is based on physical, chemical and biological parameters of Romang Polong. The researcher took 5 kinds of water as samples based on land use by applying the Storet method. The water sample was tested in the field and analyzed in the laboratory. The results obtained are compared with the specified based on criteria of water quality which indicated that groundwater in the Romang Polong is suitable to be used as drinking water quality standards at the point 2, 3, and 4. However, at the point 1 and 5 are not feasible to be used as drinking water quality standards. But, it is still feasible to use for household needs such as bathing and washing. It might be happened because the physical, chemical, and biological parameters exceeded the maximum permissible threshold based on the drinking water quality standard according to Minister of Health of the Republic of Indonesia No. 492 / MENKES / PER / IV / 2010.

Source water quality is of major concern to all drinking water utilities. The accidental introduction of contaminants to their source water is a constant threat to utilities withdrawing water from navigable or industrialized rivers. The events of 11 September, 2001 in the United States have heightened concern for drinking water utility security as their source water and finished water may be targets for terrorist acts. Efforts are underway in several parts of the United States to strengthen early warning capabilities. This paper will focus on those efforts in the Ohio River Valley Basin.

Diyala River

Diyala River is a tributary of Tigris River, it is one of the important rivers in Iraq. It covers a total distance of 445 km (275 miles). 32600 km2 is the area that drains by Diyala River between Iraqi-Iranian borders. This research aims to evaluate the water quality index WQI of Diyala River, where three stations were chosen along the river. These stations are D12 at Jalawlaa City at the beginning of Diyala River, the second station is D15 at Baaquba City at the mid distance of the river, and the third station is D17 which is the last station before the confluence of Diyala River with Tigris River at Baghdad city. Bhargava method was used in order to evaluate the water quality index for both irrigation and drinking uses. The results indicated that Diyala river water quality at its beginning was excellent for irrigation and good for drinking, while at the mid distance of the river, it was good for irrigation but heavily polluted and unsafe for drinking. Water quality of the river at the third site was acceptable for irrigation but again severely polluted and unsafe for drinking.

The University Center of Biological and Agricultural Sciences (CUCBA) of the University of Guadalajara receives approximately 5700 students, and 1500 of the academic, administrative and visiting staff. The CUCBA is research oriented, therefore, large amount of chemical waste and microbial load is generated by health services. There are two sources of water supply that provide quality drinking water to the student population and two water treatment plants that process the wastewater produced. The objective of this study was to evaluate the physical chemical and bacteriological quality of the water from the sources of supply, storage tanks, distribution network and principals points of use as an area of food and drinkers, as well as the wastewater emitted in triplicate. The water quality index was calculated, and regular values of the water quality of the 10 sampled points were found, and it is noted that, the sampling points with the lowest quality index were the water that leaves the plants of Water treatment, therefore, is not being accomplished with proper water purification.

High Disease Burden

Today, the quality of drinking water across the globe has become an environmental concern because of its degradation due to urbanization, industrialization, transportation etc. Solan, a rapidly developing district and an industrial hub, in the recent past has faced water borne diarrhoeal disease outbreaks. Therefore, the study was undertaken to assess the water quality of disease burden regions during monsoon and post monsoon seasons. pH of the water sources was in the range of 6.92- 7.43 and was well within normal limits. Electrical conductivity of water ranged from 151.40- 414.65 µS/cm. The water sources of high disease burden regions exhibited higher EC than the prescribed ICMR standards. DO (range 7.43- 8.56 mg/l) was normal in all disease burden regions. BOD (range 12.25- 23.25 mg/l) was higher than the BIS limits in all regions. The COD, TDS and turbidity (range 75.75- 157.50 mg/l, 2.24- 81.01 mg/l and 1.85- 5.05 NTU respectively) were within BIS limits. The concentrations (mg/l) of Ca, Pb, Hg, Zn and Cr was found in the ranges of 37.2- 122.9, 0.17- 0.51, 0.00- 0.03, 0.74- 8.99 and 0.04- 0.10, respectively. The high disease burden regions exhibited relatively higher contents of Ca, Hg and Cr as compared to lower one and the BIS limits. However, contents of Pb and Zn were above BIS limits in all the regions. The concentration (mg/l) of Mg, NO3-, Cl- and As was in the ranges of 14.25- 30.61, 5.10- 9.88, 16.42- 74.96 , 0.001- 0.014 respectively, which were below prescribed standards. Cd was detected (0.001 mg/l) in Solan region only, however it was within BIS limits. Water Quality Index (WQI) computed by using nine parameters varied from 78.58- 219.78 (very poor to unsafe drinking water class). Interestingly, water sources of all the high disease burden regions were unsafe for drinking (WQI: 102.02- 167.04). Water quality deteriorated more in the monsoons. The study therefore warrants remedial actions of water resource protection and conservation for provision of potable water.

Service Areas

Although the United States Safe Drinking Water Act (SDWA) theoretically ensures drinking water quality, recent studies have questioned the reliability and equity associated with community water system (CWS) service. This study aimed to identify SDWA violation differences (i.e., monitoring and reporting (MR) and health-based (HB)) between Virginia CWSs given associated service demographics, rurality, and system characteristics. A novel geospatial methodology delineated CWS service areas at the zip code scale to connect 2000 US Census demographics with 2006–2016 SDWA violations, with significant associations determined via negative binomial regression. The proportion of Black Americans within a service area was positively associated with the likelihood of HB violations. This effort supports the need for further investigation of racial and socioeconomic disparities in access to safe drinking water within the United States in particular and offers a geospatial strategy to explore demographics in other settings where data on infrastructure extents are limited. Further interdisciplinary efforts at multiple scales are necessary to identify the entwined causes for differential risks in adverse drinking water quality exposures and would be substantially strengthened by the mapping of official CWS service boundaries.

Abstract Improper solid waste management in Kano Metropolis, Nigeria has become a serious threat to human health and ground water quality. Groundwater monitoring should be conducted to assess the groundwater contamination, especially originated from leachate generated from the dumpsites. Most of the dumpsites are located nearby water body that subsequently affecting the quality of the water for human purposes. This study aims to investigate the relationships between different physical-chemical and biological parameters during the two seasons (dry and wet seasons) in Kano Metropolis area as well as to identify the sources of variation during the two seasons. The level of some physical-chemical and biological parameters of the groundwater (wells) and dump sites were assessed (i.e. temperature, pH, conductivity, suspended solids, turbidity, hardness colour, e-coli and coliform). Mean concentration of some physical-chemical and biological parameters except that of temperature, colour, pH and total dissolved solids were found to be above the acceptable limit of the National and International standard of drinking water quality, NESREA and WHO. The sources and variations of the samples results were tested using statistical analysis. The water samples show a considerable level of pollution. The analysis of the groundwater and that of dump sites reveals no significant difference in the parameters measured. It is therefore recommended that the water from this source should be monitored and treated properly before consumption.
