Water Quality
At JBA, we are able to present to you a full picture of ecological status with summaries of environmental metrics useful for strategic and detailed decision making.
With the Water Framework Directive (WFD), there will be a need to tie together all aspects impinging on the health of our water environment. Whilst we can use strategic chemical water quality sampling and modelling to understand the chemical health of a river, this does not tell the whole story of the health of our aquatic and riparian ecosystems. To understand this, the long-term influences on habitat (including geomorphology, climate change, low and high flow regimes, land management and diffuse pollution) all need to be considered. Measures of biological health are clearly the only true measure that can give the full picture of ecological good status for the Water Framework Directive.
We are able to assist with bringing together all these different elements to understand the health of our aquatic environment. For example, we supplied the Scottish Environment Protection Agency (SEPA) with a strategic tool that combined biological and chemical data to inform consenting decisions, and our understanding in flow processes and mixing has recently helped calibrate part of the Mersey-Ribble Basin Simulated Catchment (SIMCAT) model.
JBA also has experience in providing commercial operators with desktop studies of background water quality potentially affected by a development. We are able to carry out the fieldwork required to collect water quality sampling from a range of water environments which are analysed by the Environment Agency’s National Laboratory Service and presented in a laboratory report. A wide range of determinants testing can be provided or more specific chemical components can be targeted within a water environment.
Our Geographical Information System (GIS) tools help describe geomorphological typology in the form of the Watershed Toolbox and we undertake the design and build of GIS tools for clients that manipulate and query raster and vector data to provide robust solutions for particular problems. Coupled with this, we offer a rich suite of statistical tools honed for the river environment, for example, time series analysis, interpolation of probability along networks and frequency analysis of spatial data.
To see how we can help you with your water quality needs, please contact Barry Hankin or Mark Tywang.
