  • Standardizing defluoridation of community waters using bone char

    Different bone char (BC) preparation methods affect the physical chemical properties and therefore the capacity to remove fluoride. Fluoride removal capacities of BC prepared at three controlled temperatures, with particle grain sizes of 250–500 μm, 500–1,000 μm and 1,000–1,800 μm were determined in column experiments with an initial fluoride concentration of 8.55 mg/L. The sorbent was ...

  • Ultrapure water – The standard for resistivity measurements of Ultrapure water - Case Study

    Abstract For years, resistivity/conductivity2 instrumentation has been used as a reliable indicator of ionic water quality, especially for ultrapure water (UPW). Traditionally, the instrumentation is procured, installed, powered up, and perhaps connected to a PLC, strip chart recorder, or a LAN. After that, the instrument and sensor receive no attention until a problem arises. Today, ...

  • Standard Chlorine of Delaware Remediation

    By designing a 70-foot deep barrier wall, Black & Veatch was able to cut off contaminant source areas from a creek near New Castle, Delaware. The groundwater treatment system that Black & Veatch designed prevents site contamination from reaching the underlying drinking water aquifer. The Standard Chlorine of Delaware Site is a 65 acre area including an abandoned chlorobenzene ...

  • Types of Environmental Standards

    Different kinds of environmental standards can serve quite different purposes in environmental policy. This note outlines these differences Ambient Standards Ambient standards set maximum allowable levels of a pollutant in the receiving medium (air, water and soil). Ambient standards can offer a simple method of establishing priorities since areas (or stream lengths) which ...


  • Emission standards versus immission standards for assessing the impact of urban drainage on ephemeral receiving water bodies

    In the past, emission standard indicators have been adopted by environmental regulation authorities in order to preserve the quality of a receiving water body. Such indicators are based on the frequency or magnitude of a polluted discharge that may be continuous or intermittent. In order to properly maintain the quality of receiving waters, the Water Framework Directive, following the basic ideas ...

  • Asbestos in water? How to address ‘non-standard’ samples of industrial and other effluents

    Biohazards and other interferences complicate the employment of off-the-shelf asbestos in water methods by traditional TEM techniques. Laboratories must implement creative strategies to prepare and analyze these samples to produce meaningful analytical data. Laboratory and personnel safety have to be considered before sample handling. The interferences also greatly diminished any reasonable ...

  • Derivation of water quality standards for carbamazepine, metoprolol and metformin and comparison with monitoring data

    Environmental quality standards (EQSs) for three pharmaceuticals in surface water were derived: carbamazepine (epilepsy), metoprolol (heart failure) and metformin (diabetes). During the past years, these pharmaceuticals have been detected frequently in Dutch surface waters. The proposed standards are based on ecotoxicity data from national and European authorisation dossiers and additional ...
