    Notes: [Auszug] MY attention has been directed to a letter in NATURE of November 24 over the signature of Prof. J. Wilson. He disputes the accuracy of certain extractions from “The General Stud Book”, which originally appeared in The Veterinary Record, in my paper on the inheritance of dun coat-colour. Prof. ...

    Notes: Abstract Many states within the United States as well as many other countries have promulgated regulations addressing public health, consumer protection, and truthin-labeling aspects of the extraction, bottling, and labeling of commercially bottled springwater intended for public consumption. Many of these regulations are inconsistent, suggesting a need for more uniform standards in acceptable extraction methods and legal/technical definitions of “spring” and “springwater.” An objective of the extraction or collection method is protecting the quality and integrity of the springwater, especially against microbial contamination. A summary of microbiological issues associated with groundwater and springwater is presented. Acceptable extraction methods can be either surface collection boxes/houses at the discharge point of the spring or a subsurface borehole or gallery interception system. Although extraction wells can provide total protective isolation of the water, a potential concern with that method is providing assurance that the extracted water is in fact the same water that feeds the adjacent spring. Criteria for testing this requirement are suggested in the paper.

    Notes: Because branched-chain alkyl benzene sulfonate (ABS) is well known to create water pollution problems in surface water and ground water, a study was made on the biodegradation of this surfactant along with other anionic and nonionic surfactants in detergents by water bacteria. Biodegradation was evaluated by the conventional river die-away test employing the methylene-blue method or surface-tension techniques as analytical tools. Under anaerobic conditions, sugar detergents (sucrose esters) seem to be an ultimate solution to water problems created by branched-chain ABS; in aerated water, straight-chain ABS, sulfo tallow methyl esters, and nonionic surfactants are preferable to branched-chain ABS to improve water problems.
