Summary: The widespread use of pesticides leads to contamination of groundwater, which has negative impacts on the environment and poses a threat to life. A study conducted in 15 districts of the Punjab province in Pakistan revealed the presence of chemical residues from major pesticide groups in the water samples. Highly contaminated groundwater was found in districts with intensive pesticide use, while districts with lower pesticide usage had lower levels of contamination. This issue highlights the importance of implementing integrated pest management and non-chemical pest control strategies.

Summary: This study presents machine learning predictions of customers' service line materials in Pittsburgh, PA and discusses their impact on improving municipal lead programming. The predictions are based on a combination of property characteristics, administrative spatial data, and tap water quality samples. The study also uses photographs of service line materials taken at the curb box as labels to boost predictions. However, the precision of the predictions declines when applied to a larger customer base, limiting their ability to estimate system-wide inventories and inform regulatory decisions.

Summary: In order to ensure public safety and health, it is necessary to develop a quick analytical technique to monitor the quality of filter plants and bottled water. This study analyzed the spectra of different water samples and found that poor quality water showed high intensity fluorescence emission in the blue green region and low intensity water Raman peak, while pure water exhibited an intense water Raman peak when excited at 365 nm. The emission intensity in the blue green region and water Raman peak can be used as markers for quick screening of water quality.

Summary: This study evaluates the sources and controlling factors of groundwater contaminants in an agroeconomic region of the Lower Ganga Basin. The findings indicate that the dissolution of fluoride-bearing minerals and semi-arid climate regulate fluoride concentrations in groundwater, while the extensive use of inorganic nitrogenous fertilizers and livestock manure contribute to elevated nitrate levels. The health risk analysis reveals that fluoride exposure is more prevalent in residents of all age groups compared to nitrate, and both contaminants pose higher non-carcinogenic health risks to infants and children.

Summary: The use of primitive techniques in recycling electronic waste has resulted in severe soil pollution. Remediation techniques such as spray tower, electronic precipitation, photocatalysis, and phytoremediation using suitable plants and microbes are recommended to decontaminate soil, sediment, and water contaminated by toxic metals and persistent organic pollutants. Proper vegetation can also extract, stabilize, and degrade pollutants, restoring soil functions and health.

Summary: Residents may lose trust in drinking water systems and turn to alternative water sources when encountering water-quality issues. The erosion of trust can be caused by breakdowns in communication, poor handling of issues, or misconceptions about water quality. This study found that trust is related to individuals' actions and interactions with the water system.

Summary: A large building with recurrent leaks in the hot water recirculating line was investigated. The leaks occurred on the top half of heavily coated pipes. Under-deposit corrosion was ruled out as the cause, while a chemistry-related hot water pitting mechanism was hypothesized. The hypothesis was verified by conducting macrocell experiments, which showed that copper or stainless steel coated with manganese oxides exhibited high cathodic tendencies, leading to pitting corrosion.

Summary: Water utilities dose phosphates to potable water for reducing aesthetic problems, inhibiting scale formation, and reducing corrosion. However, there are significant gaps in understanding due to proprietary nature of some phosphate chemicals. This article summarizes the current state of the science, provides operational guidance, and identifies knowledge gaps to improve phosphate chemical performance and avoid unintended consequences.

Summary: Distribution of reclaimed water poses unique challenges for pathogen control in comparison to conventional potable water. Elevated temperatures in arid regions can worsen these challenges by accelerating disinfectant decay and promoting microbial growth. A study was conducted to assess the effectiveness of microbiological control treatments at different temperatures by analyzing six simulated reclaimed water distribution systems. The results showed that certain treatment methods were less effective at higher temperatures, indicating the need for further research to control specific pathogens under elevated temperature conditions.

Summary: This study investigates the effects of copper on the microbial community in hot water plumbing systems. The results show that even low doses of copper can have an impact on the broader microbial community and that opportunistic pathogens in the system are highly copper tolerant. The addition of orthophosphate can reduce the bioavailability of copper. Functional gene analysis suggests that membrane damage and interruption of nucleic acid replication may be involved in the copper inactivation mechanisms.

Summary: The quantitative evaluation of the chemical stability of cement mortar lining (CML) in cement mortar lined iron pipes under different drinking water conditions is still lacking. This study investigated the leaching of pipe material into water and changes in surface properties using pipe reactors. Results showed that water with hardness and alkalinity higher than 30 mg/L can significantly decrease the release of CML material by forming a calcium carbonate layer. The formation of the calcium carbonate layer can occur even if the initial water calcium carbonate precipitation potential (CCPP) is negative.

Summary: There are uncertainties regarding the factors influencing Legionnaires' disease outbreaks in Flint, MI after a change in water source and interruption of corrosion control. The incidence of LD associated with residential exposure in summer 2015 was lower compared to 2014. A bench-scale study revealed that Legionella pneumophila grew extensively in the presence of cross-linked polyethylene pipes, but at lower levels with copper pipes. The addition of phosphate to copper pipes decreased copper levels and increased L. pneumophila to levels comparable with PEX pipes.
