Although phosphorus (P) is an essential nutrient for biological productivity, it can cause
freshwater degradation when present at fairly low concentrations. Monitoring studies using …

The validity of load estimates from intermittent, instantaneous grab sampling is dependent
on adequate spatial coverage by monitoring networks and a sampling frequency that reflects …

This paper examines two hydrochemical time-series derived from stream samples taken in
the Upper Hafren catchment, Plynlimon, Wales. One time-series comprises data collected at …

This review considers enhanced approaches to river water quality monitoring in north-
western Europe following a series of study visits (11 sites in 7 countries). Based on the …

A small scale and temporally limited CO 2 injection test was performed in a shallow aquifer
to investigate the geochemical impact of CO 2 upon such aquifers and to apply and verify …

Enhanced knowledge of water and solute pathways in catchments would improve the
understanding of dynamics in water quality and would support the selection of appropriate …

The suitability of passive samplers (Chemcatcher) as an alternative to grab sampling in
estimating time-weighted average (TWA) concentrations and total loads of herbicides was …

Nutrient enrichment and loadings of pharmaceuticals and agrochemicals into freshwater
systems are common concerns, especially for water bodies receiving wastewater inputs. In …

The retention of phosphorus in surface waters through co-precipitation of phosphate with Fe-
oxyhydroxides during exfiltration of anaerobic Fe (II) rich groundwater is not well …
