  • A Regulatory Perspective on Maintenance of Disinfection Systems

    ABSTRACTThe Clean Water Act contains requirements to set water quality standards for all contaminants, including bacterial contaminants, in surface waters. Wastewater treatment cannot be expected to remove all of the bacterial contaminants, and as a result, many organisms remain in the waste stream. Therefore, disinfection of treated wastewaters is designed to reduce bacterial numbers to a safe ...

  • PPCPs: Preparing for an uncertain regulatory future

  • Common Regulatory Practices in Onsite Wastewater Programs: A Willing Suspension of Disbelief

    The phrase “a willing suspension of disbelief,” coined by Samuel Taylor Coleridge in his Biographia Literaria published in 1817, refers to the willingness of a person to accept as true the premises of a work of fiction, even if those premises are fantastic or impossible. Prescriptive codes regulating onsite wastewater often carry forward the relics of previous generations even as new ...

  • Biodosimetry of a full-scale uv disinfection system to achieve regulatory approval for wastewater reuse

    In order to respond to the stringent disinfection requirements for reclaimed wastewater in the United States, Ozonia North America (ONA) undertook a bioassay validation study of a lowpressure nvery high-output (LPVHO) ultraviolet (UV) disinfection system. The disinfection performance of this process technology was verified via biodosimetry in accordance with the Ultraviolet Disinfection ...

  • Clearing Regulatory & Financing Hurdles a Border Town Success Story

    ABSTRACT:Construction and operation of the new City of Somerton (the City) Wastewater Treatment Plant (WWTP) supports the City’s economic development, assists the City with continued growth, and resolves specific human health and environmental issues. The old lagoon treatment facility frequently discharged less than optimal effluent as a result of overload at peak flow rates. With a series of ...

  • Is there mercury in your industrial wastewater discharge?

    An assessment of sampling locations for three industrial wastewater effluent piping systems is presented. The assessments provided demonstrate that by installing sampling ports at the appropriate location along an effluent stream’s piping system, truly representative samples can be collected. These real and accurate results scientifically prove that a specific industrial wastewater ...

  • Regulatory Aspects of Direct Potable Reuse in California

    Introduction California's water supplies are derived from a variety of sources, including local and imported surface water, groundwater, desalinated seawater, and recycled water. Water resources are becoming limited due to population increases, droughts, and reductions in imported water allocations. Furthermore, global climate change may exacerbate the problem in the future. Water ...

  • Treatment of industrial wastewater

    All industries produce some type of waste product, either from production, maintanance or both. These hazardous and non-hazardous wastes need to be properly stored, treated and discharged to a sewer system or otherwise disposed of.

  • Maintaining regulatory method compliance while automating oil and grease analysis

    Regulatory compliance is at the heart of environmental analyses throughout the world. While some regulatory systems provide more flexibility in the methodology used for measuring contaminants, the goal is to gain reliable information that can be used for decision-making. Oil and grease measurement is a simple and important measurement of water quality, but time consuming1. Methods such as US EPA ...

    Arsenic in industrial wastewater effluents is attracting greater regulatory attention. Depending on factors such as total maximum daily loads (TMDLs), the National Pollutant Discharge Elimination System (NPDES) discharge permit levels for arsenic may even be less than the drinking water standard of 10 µg/L. One of the industries affected by stringent arsenic discharge limits is coal-fired power ...

  • Matching Oil in Water Analyses with Regulatory Methods - Case study

    When analyzing oil and grease in water while out in the field, it is important to use an EPA approved method and equipment.
