A spatially intensive approach to water quality monitoring in the Rous River catchment, NSW, Australia

Article Abstract:

Water quality monitoring gives enables managers to identify the key causes of poor water quality in a system. Water quality in the Rouse River catchment northern New South Wales, Australia, has been identified as poor. It was used as a case study to test a spatially intensive water quality monitoring method and to evaluate the quality of information provided. The method was found to be rapid, cost-effective and robust, despite some limitations. Management efforts in the area must be aimed at reducing point source inputs as well as non-point source inputs, and reducing direct cattle access to streams.

Time series analysis of historical surface water quality data of the River Glen catchment, U.K

Article Abstract:

The methodology using multiple regression analyses is better than the traditional time series analyses, to study the total oxidized nitrogen (TON) concentration trends. The model is also functional for data with gaps. Solute concentration increases in winters and decreases in summers. TON levels in U.K. have risen by 50-400% over twenty years. The global median nitrogen concentration excluding Europe is 0.25 mg. The European level is 4.5 mg. Many rivers have solute levels equal to or above World Health Organization and European Community drinking limits.

Residents' perceptions of water quality improvements following remediation work in the Pymme's Brook catchment, north London, UK

Article Abstract:

The article examines results of a survey used to assess public opinion on the efficacy of urban runoff bioremediation in a London, UK neighborhood, and then assesses the reliability of the survey itself. While public opinion overall was found to be positive concerning the results of bioremediation, parameter subdivisions revealed variances in responses, indicating that public opinion surveys used to quantify benefits can be problematic.
