  • Effect-based trigger values for in vitro and in vivo bioassays performed on surface water extracts supporting the environmental quality standards (EQS) of the European Water Framework Directive

    Abstract Effect-based methods including cell-based bioassays, reporter gene assays and whole-organism assays have been applied for decades in water quality monitoring and testing of enriched solid-phase extracts. There is no common EU-wide agreement on what level of bioassay response in water extracts is acceptable. At present, bioassay results are only benchmarked against each other but not ...

  • Why You Should Monitor Groundwater?

    What is groundwater? Groundwater is water that is stored below the earth’s surface. When rain or other sources of water come into contact with the ground, the majority of it travels below the surface. Though much of this moisture is then absorbed by plants or returned to the atmosphere (through infiltration), some water will travel deeper beneath the surface – where it ...

  • Surface Water Monitoring - Case Study

    Safe operation of a Water Treatment Plant (WTP) requires careful monitoring of the water supply influent to the plant, as a guard for any substances entering the treatment works that could negatively impact treated water quality in the distribution system. One aspect of water quality that has recently garnered more attention from authorities and utilities is Natural Organic Matter (NOM), which ...

  • Why Interactive Ultrasonic Programs are Important to Effectively Control Algae

    Many different algal types can bloom in a water body. Some of these algae are plant cells, while others are bacteria. Algae may vary in size, shape and cell characteristics. Typically, the type of algae that blooms depends on water temperature and sun hours. As a result, algal types may change several times during a season. To effectively  ...

  • Validation of Salt Water Disposal Well Treatment Plants with Handheld Oil in Water Sample Analyzer

    Salt Water Disposal (SWD) well operators often dispose a substantial volume of oil inadvertently when injecting salt water, thereby losing the opportunity to sell the oil on the market and potentially reducing the ability to inject water in the well. Injection facilities are typically operated with minimal instrumentation or system optimization, which means the operators don't know how much, or ...
