Drinking water standards specify the desired quality standards for water used for drinking purposes. The Drinking-water Standards for New Zealand (DWSNZ) is reinforced by Section 69A of the Health Act 1986 which advocates for the provision of potable drinking water…
The Chemical Abstract Service (CAS) is part of the American Chemical Society, and it is used to maintain a database of chemical compounds, substances, and alloys. The CAS database contains over 100 million different chemical compounds. Each CAS entry is…
The Federal Interim Groundwater Quality Guidelines was developed by federal authorities to facilitate the assessment, remediation and risk management of federal contaminated sites which are under the funding of the Federal Contaminated Sites Action Plan (FCSAP). The guidelines are applicable…
The availability of safe drinking water is an essential requirement for all New Zealanders, irrespective of their status. The NZ Drinking Water Standards, as set by the Ministry of Health, provide requirements for drinking water safety by stipulating; (1) maximum amounts…
The Mann Kendall Trend Test is sometimes also named as Kendall’s tau test or Mann Kendell Test (or M-K test). This test is utilized for the analysis of data that is collected for a sufficient period for representing a continuous increasing or…
Environmental concerns necessitate the need for policies which serves to sustain human health, protect plant and animal life as well as prevent damage to the environment. In addition to other natural resources, the Natural Resources Management Act 2004 (NRM Act) is responsible…
The Environment Protection (Water Quality) Policy 2003 (Water Quality Policy) is a policy that safeguards South Australian water resources from pollution. For a long period, the discrepancies surrounding the South Australian laws protecting the State’s water resources from pollution, have lowered…
The Schoeller diagram is used to illustrate the relative concentrations of anions and cations. These concentrations are usually expressed in milliequivalents per litre. A Schoeller diagram can be used to compare concentrations from different water sources. An example is whereby…
The Department of Environment adopted the National Health and Medical Research Council (NHMRC) Guidelines for Managing Risks in Recreational Waters (NHMRC 2008), Climate Change and Water (DECCW) to enforce the protection of human health. Human health protection is spearheaded through…
Soil Generic Assessment Criteria for Human Health Risk Assessment is a technique used to examine the dangers which result from the release of pollutants into the land. The risks are identified and the likely impact of damage determined. Generic Assessment…
Assessment levels for Soil and Sediment in Western Australia were adopted by the Department of Environment and Conservation (DEC) to provide measures which are used in determining whether sites are contaminated. The assessment covers substances which threaten human health and…
The Government of Western Australia through its Department of Water and Environmental Regulation has the authority and mandate to measure the quality of groundwater and surface water across the country. The primary objective of carrying out an assessment of water…
Geotechnical Borehole LoggingGeotechnical borehole logging involves the use of boreholes to perform investigations on materials from deep underground for geotechnical designs. The approach is applied for obtaining information on ground movements, groundwater levels, material strengths, permeability, and pore pressures. Geotechnical…
The Canadian Council of Ministers of the Environment (CCME) is responsible for the provision of Canadian environmental quality guidelines aimed at the protection of aquatic and terrestrial ecosystems as well as human health. CCME established the “Recommended Canadian Soil Quality…
Arthur M. Piper introduced Piper diagrams in 1994. It is used for studying water chemistry and quality. The Piper diagram helps to segregate analytical data necessary for determining the sources of the constituents dissolved in water. The procedure’s applicability is possible due…
Linear regression refers to an analysis technique which involves modelling a relationship between two variables (one being an independent variable and the other a dependent variable) and integrating a linear equation to the data. Through linear regression analysis, we can make…
