Designing monitoring programs for chemicals of emerging concern in potable reuse – what to include and what not to include?
This study discussed a proposed process to prioritize chemicals for reclaimed water monitoring programs, selection of analytical methods required for their quantification, toxicological relevance of chemicals of emerging concern regarding human health, and related issues. Given that thousands of chemicals are potentially present in reclaimed water and that information about those chemicals is ...

Project - Lake Association Monitoring
Our ColiPlate water testing system has been a popular choice amongst Lake and Cottage Associations who run volunteer water monitoring programs. Coliplate test kits are ideal for these community-based monitoring programs as these kits are user-friendly, may be used by inexperienced/non-technical individuals and can be employed in remote areas as they do not require laboratory facilities, enabling ...

A Framework for Assessing Cumulative Effects in Watersheds: An Introduction to Canadian Case Studies
From 2008 to 2013, a series of studies supported by the Canadian Water Network were conducted in Canadian watersheds in an effort to improve methods to assess cumulative effects. These studies fit under a common framework for watershed cumulative effects assessment (CEA). This paper presents an introduction to the Special Series on Watershed CEA in Integrated Environmental Assessment and ...

EQuIS milestone
EQuIS now contains over 15 million chemical/physical discrete monitoring results after the recent completion of the EDMS (Closed Landfills) database migration. Growth for other MPCA Remediation and Solid Waste programs will depend on the rate that labs and contractors adopt the new standard lab and field EDD submittal formats and on associated location establishment. Groundwater and surface water ...

Water quality assessment using multivariate statistical techniques in Río Tercero Reservoir, Argentina
Water quality monitoring programs generate complex multidimensional data sets. In this study, multivariate statistical techniques were employed as an effective tool for the analysis and interpretation of these water quality data sets. Principal component analysis (PCA) and cluster analysis (CA) were applied to evaluate spatial and temporal variation of water quality in Río Tercero ...

Aminomethylphosphonic acid (AMPA) has low chronic toxicity to Daphnia magna and Pimephales promelas
Aminomethylphosphonic acid (AMPA) is the simplest member of a class of compounds known as aminomethylenephosphonates and the only environmental metabolite measured in significant amounts during the degradation of the herbicide glyphosate in soil. However, there are additional sources of AMPA in the environment, originating from organic phosphonates which are used in water treatment to inhibit ...

Supply system factors associated with microbiological drinking water safety in regional New South Wales, Australia, 2001–2007
Aim: To determine factors associated with microbiological safety of public drinking water systems in regional New South Wales (NSW), Australia. Method: We analysed 107,000 end-user drinking water samples for an association between detection of Escherichia coli and drinking water system features, sample year and season using NSW Health Drinking Water Monitoring Program data, 2001–2007. We used ...

NPS, Eastern River and Mountains Network - Case Study
Overview Since 1999, the National Park Service has conducted long-term ecological monitoring designed to identify and monitor conditions of their highest priority natural resources. The Eastern Rivers and Mountains Network is one of 32 networks formed to implement this integrated monitoring program which is tailored to specific needs of parks located in similar environmental settings. Due to its ...

Cyto- and genotoxic profile of groundwater used as drinking water supply before and after disinfection
The assessment of the toxicological properties of raw groundwater may be useful to predict the type and quality of tap water. Contaminants in groundwater are known to be able to affect the disinfection process, resulting in the formation of substances that are cytotoxic and/or genotoxic. Though the European directive (98/83/EC, which establishes maximum levels for contaminants in raw water ...

Application of water pollution detector
Background: The (nitrate) link between agriculture and water quality is nutrient abundance - I've always thought the main issue was with fertilizers. Excessive nutrient loss often leads to eutrophication of surface waters. This condition can lead to harmful algal blooms (HAB), which produce dangerous toxins and cause a drop in dissolved oxygen, killing fish in both marine and freshwater ...

Water recycling in Western Australia: analysis of 2003–2009 water quality monitoring programme
Water-recycling schemes have been in operation in Western Australia since 1960. As a requirement of the regulatory framework for wastewater reuse, periodic water quality monitoring has been implemented to demonstrate microbial compliance for the intended end-use. For this study, we originally planned to analyse the compliance of the 92 water recycling schemes in the database over a 7 year ...

The Effectiveness of Intrawell ground water monitoring statistics
Abstract The reality of the new statistical evaluation requirements for ground water at Subtitle D facilities are being felt nationwide. All too often these requirements are resulting in unnecessary increases in ground water monitoring costs and erroneous indications of facility impacts. For example, a common situation faced by many older facilities is that there is statistically significant ...
