Considerations for Addressing Problematic Compounds in Vapor Intrusion Evaluations

Remediation Journal, Volume 36, Issue 4, Autumn 2026.
ABSTRACT Vapor intrusion (VI) investigations involve the performance of environmental assessments for the potential presence of vapor‐forming chemicals in groundwater, soil, exterior and interior (sub‐slab) soil vapor, and indoor air. VI‐decision‐making is generally guided by simple comparisons of detected concentrations to media‐specific screening ...

Survey of the effective factors in the production of HAAs and measuring their concentration in the Tehran outlet water treatment plants in the first half of 2010

سلامت و محیط, 2014
Background and Objectives:Chlorination is the most common method of water disinfection. Chlorine reaction with natural organic compounds nor removed completely during treatment process would result in forming disinfection byproducts.

Investigation into Trihalomethanes in Lager Beers Brewed in Ghana [PDF]

, 2017
Water is a vital ingredient in beer constituting 91-98% of the content. In Ghana, the main source of water for the two major breweries in the city of Accra is from the Ghana Water Company which takes its source from the Weija Dam and the quality of the ...

Estimating Operational Costs of Activated Carbon for Water Treatment Plants by Predicting the Rise of Harmful Algal Blooms Under Climate Change in Korea Using Machine Learning

Water Environment Research, Volume 98, Issue 3, March 2026.
This study investigated future operational costs in water treatment (WT) plants. Random forest modeling projected 3–5 times more abundant cyanobacteria by 2100 due to climate change. Increased microcystins demanded substantially more activated carbon and, as a result, WT costs could rise to $6–22/household/month.

A Software System for Predicting Trihalomethanes Species in Water Distribution Networks Using Online Networked Water Sensors

, 2020
Drinking water chlorination reduces the risk of pathogenic infection, but it may be harmful to human health because of trihalomethanes formation. At present, trihalomethanes concentrations are periodically monitored in fixed points along the water ...

Fenton Treatment of Filter Backwash Water for Recycling in DWTP

Water Environment Research, Volume 98, Issue 3, March 2026.
The graphical abstract illustrates the treatment and recycling pathway of filter backwash water (FBW) generated in drinking water treatment plants. The proposed treatment innovatively applies the Fenton advanced oxidation process, using the iron naturally present in the FBW, with a sedimentation step for effective clarification. ABSTRACT Drinking water

Ships’ Ballast Water Treatment by Chlorination Can Generate Toxic Trihalomethanes [PDF]

, 2017
The International Maritime Organization (IMO) will enforce a new abundance-based performance standard for ballast water in September, 2017. Strong oxidants, like chlorine, have been proposed as a method for achieving this standard.

Interactions of chlorine with tropical aquatic fulvic acids and formation of intermediates observed by fluorescence spectroscopy

Journal of the Brazilian Chemical Society, 2004
The interactions of tropical aquatic fulvic acids (AFA) with chlorine and formation of trihalomethanes were characterized by fluorescence spectroscopy. The aquatic humic substances (AHS) were isolated from a dark-brown stream (located in a environmental ...
