Drinking Water Analysis Guide
Public Water Systems (PWS), regulated by the United States Environmental Protection Agency (USEPA), provide drinking water to 90% of Americans. Water systems and laboratories testing drinking water for Safe Drinking Water Act (SDWA) compliance must be certified and must use USEPA approved methods, which are developed by the USEPA, other government agencies, universities, consensus method ...

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 ...

Impact of environmentally based chemical hardness on uranium speciation and toxicity in six aquatic species
Treated effluent discharge from uranium (U) mines and mills elevates the concentration of U, calcium (Ca), magnesium (Mg) and sulfate (SO42‐) above natural levels in receiving waters. Many investigations on the effect of hardness on U toxicity were often experiments on the combined effect of changes in hardness, pH and alkalinity which do not represent water chemistry downstream of U mines and ...

Home water treatment by direct filtration with natural coagulant
ABSTRACTSeeds of the plant species Strychnos potatorum and Moringa oleifera contain natural polyelectrolytes which can be used as coagulants to clarify turbid waters. In laboratory tests, direct filtration of a turbid surface water (turbidity 15-25 NTU, heterotrophic bacteria 280-500 cfu ml−1, and fecal coliforms 280-500 MPN 100 ml−1), with seeds of S. potatorum or M. oleifera as ...

Leaching of bisphenol A and F from new and old epoxy coatings: laboratory and field studies
Laboratory tests were carried out with three types of new epoxy resins to assess the release of bisphenol A and F (BPA and BPF) and potential halogenated phenolic by-products. Tests were carried out over a duration of 6 months in the presence and absence of disinfectants (chlorine and chlorine dioxide) at realistic doses and contact times. None of the three systems exhibited Fickian-type ...

Coupling microbiological testing and sanitary surveys in drinking water quality programs: results from Capiz Province, Philippines
Developing countries often struggle to conduct laboratory-based water quality testing programs due to a lack of financial and technical resources. However, inexpensive, accurate, field-based tests are being developed which have the potential to overcome this barrier. This paper provides the results of an initiative by the Provincial Health Office in Capiz, Philippines, to conduct a first-ever, ...

LIMS Essential for H2O Testing
Clean water is a global necessity - essential to our health and well being. Just imagine a day without clean water to drink, to prepare our food, to wash the daily grind from our clothes and bodies. There’s a lot of science behind clean water and a laboratory information management system (LIMS) is a critical component of the sample management, data capture and analysis that is necessary ...

Superior Manufacturing Division, Magnatech Corporation Case study
15 Years of Saving the Environment Some companies seem to always be ahead of their time. Rather than going with the flow, they choose to step out and try something different. That’s what often leads them to success. L&L Products of Romeo, MI, is one of these mastermind companies. The intellectual wheels of Robert Ligon and Eugene Lane started turning in 1958 after realizing a need for ...

4 Benefits of Electrocoagulation for Arsenic Removal from Water
In water and wastewater treatment, arsenic is classfied as a heavy metal. It is well known for its toxicity and it can cause numerous health problems in humans if consumed at high enough doses. Arsenic can affect the skin, liver, kidneys, bladder, and prostate as well as the nervous, respiratory, cardiovascular, immune, and endocrine systems. Due to the many health risks associated with ...

Automated Data Management Helps Labs Meet Regulatory, Reporting Requirements
THE NELAC (National Environmental Accreditation Conference) standards published in 2003 were revised and made available in July 2011 as the new TNI Standard 2009. Implementation of this updated standard, which is based on ISO 17025 guidance, will become a reality in the next year. For water system operators and testing labs, implementation requires not only adherence with ISO 17025 standards but ...

Munox SR Remediates Oil Seepage on Caribbean Island
Munox SR bioaugmentation remediated petroleum seepage on a Caribbean Island by NRG Save of Toronto. For several years on-going surface seepage from a crude petroleum leak was collected in a pit to prevent further surface flow. Recently, Munox SR was added to the pit and to the ground surface. After 6 days the water in the pit was visibly cleaner. After 12 days laboratory tests of the water in ...

Bacterial biofilms formed in arsenic-containing water: biodeterioration of water network materials
The immersion of any material in a water system triggers a surface microbial colonization which simultaneously influences the corrosion behavior of the substratum. The present study was focused on the As(V) influence on the biofilm formation and their consequences on the corrosion behavior of different substrata. Commercial materials used in water distribution networks: alloys based on Fe, Zn ...

Laboratory validation of an ozone device for recreational water treatment
Obtaining an accurate assessment of a treatment system's antimicrobial efficacy in recreational water is difficult given the large scale and high flow rates of the water systems. A laboratory test system was designed to mimic the water conditions and potential microbial contaminants found in swimming pools. This system was utilized to evaluate the performance of an in situ ozone ...
