How often does the WQI change in ground water due to seasonal variations?
Best insight from top research papers
Seasonal variations impact the Water Quality Index (WQI) of groundwater differently across studies. In Yavatmal District, India, the WQI ranged from 73.0 to 80.2 during pre-monsoon and 68.7 to 72.4 in post-monsoon seasons, showing slight seasonal variation . Similarly, a study on groundwater samples from different seasons revealed that none of the samples were unfit for drinking based on WQI, but all were categorized as moderately polluted by the Synthetic Pollution Index (SPI) during both pre and post-monsoon periods . On the other hand, a study on the Shitalakshya River near Haripur power station found that the WQI values varied significantly over five years, classifying the water as poor in quality based on different assessment methods . These variations highlight the importance of monitoring and assessing groundwater quality across different seasons.

Does the seasonal variation in temperature have a significant impact on sinkhole events?5 answersSeasonal temperature variations do have a significant impact on sinkhole events. Research in Florida and Italy shows that climatic patterns, including temperature changes, correlate with sinkhole formation. In Florida, colder temperatures during frost-freeze events lead to groundwater level drops, increasing sinkhole development risks. In Italy, intense rainfall events during specific seasons trigger sinkholes, highlighting the influence of seasonal weather patterns on sinkhole occurrences. Additionally, studies emphasize the role of temperature in controlling gas concentrations in caves, impacting karstification processes and speleothem formation. These findings underscore the importance of considering seasonal temperature variations in assessing and predicting sinkhole events.
How does the seasonal variation of temperature impact the rate of sinkhole formation and collapse?4 answersSeasonal temperature variation significantly impacts sinkhole formation and collapse rates. Studies show that in Florida, sinkholes are more likely to occur when temperatures are low and precipitation is also low, especially in winter months like January. Additionally, the seasonal variation of rainfall and groundwater levels plays a crucial role in sinkhole occurrence, with sinkholes most likely to form when the local-scale head difference remains constant at a peak value after a sharp increase over a short period of time. Furthermore, the mechanism of sinkhole formation is influenced by karst development and groundwater fluctuation, where soil caves progressively develop until a sinkhole event occurs. These findings highlight the intricate relationship between seasonal temperature changes, precipitation, and groundwater levels in driving sinkhole formation and collapse.
Does the presence of certain chemicals or pollutants in wastewater affect the correlation between bacterial growth and season?5 answersThe presence of certain chemicals or pollutants in wastewater can affect the correlation between bacterial growth and season. Studies have shown that wastewater treatment plants (WWTPs) can release chemicals of emerging concern (CECs) into the receiving water, which can impact microbial biomass and bacterial metabolic diversity. Additionally, the composition of microorganisms in activated sludge (AS) used in wastewater treatment can be influenced by the raw sewage composition, technological solutions, and temperature of the wastewater. Environmental factors such as dissolved oxygen concentration and pH can also affect microbial communities and interactions in WWTPs. Furthermore, the fate and transport mechanisms of fecal bacteria in surface water can vary with seasonal hydrologic conditions. Overall, the presence of certain chemicals or pollutants in wastewater can alter the microbial composition and activity, potentially affecting the correlation between bacterial growth and season.
Why As Amopunt is high in dry season groundwater?5 answersThe high amount of arsenic (As) in dry season groundwater can be attributed to the prevalence of illegal artisanal mining in the area, as mentioned in. This mining activity has polluted streams and rivers, which are the main sources of groundwater for drinking. The study found that 5% of the groundwater samples were classified as very poor for domestic use due to high levels of arsenic. Additionally, the computed non-carcinogenic and carcinogenic risks of arsenic ingestion showed that children were more vulnerable to potential cancer risk than adults. However, it is important to note that the abstracts do not provide specific details on the reasons behind the high arsenic levels in dry season groundwater.
What are the factors that contribute to seasonal variation of PM?5 answersThe factors that contribute to seasonal variation of PM include temperature, absolute humidity, biomass burning, photochemical reactions, and anthropogenic activities. Temperature and absolute humidity influence the reversible reaction of NH₄NO₃, leading to a unique seasonal distribution pattern of NO₃-. Burning biomass during autumn and winter increases the amount of organic carbon (OC) and elemental carbon (EC) in PM, while WSOC and the ratio of char-EC/soot-EC show a similar pattern. Photochemical reactions during summer lead to the formation of secondary organic carbon (SOC) and higher levels of WSOC. Anthropogenic activities and biomass burning contribute to higher concentrations of black carbon (BC) and PM during winter. In addition, traffic, mineral dust, industry, combustion, and microbial components from Gram-positive and -negative bacteria are identified as sources of PM, with their contributions varying seasonally.
How do seasonal temperature variations affect residential heat??5 answersSeasonal temperature variations have a significant impact on residential heat. In the summer, positive human activity signals (HAS) lead to higher weekday temperatures during daytime hours, especially in downtown office and mixed-building districts. On the other hand, in the winter, negative HAS cause lower weekday temperatures throughout all districts during daytime hours, with the maximum negative values occurring between 1200 and 1500 h. The increase in heat pump air-conditioning is a major factor contributing to the negative HAS in winter daytime hours. Additionally, in winter, there is a night-time positive HAS, particularly in inland residential districts, due to the gradual ventilation of heated indoor air and outgoing sensible heat transfer from the walls of buildings with heating systems. These seasonal variations in temperature affect the energy consumption and thermal comfort in residential buildings.
