Emerging substances in the watercycleEmerging substances enter the water cycle through point sources
such as effluent discharges from wastewater treatment plants and
industries, and from diffuse sources as agriculture and urban storm
water runoff. The diffuse sources are through their nature difficult to
monitor and control. In the TAPES project the control and management
of emerging substances is addressed through a concerted action. Key
players responsible for surface water and groundwater bodies, those
responsible for the treatment of wastewater and those responsible for
the production of drinking water work together to jointly address the
control of emerging substances.

DDDID approachTAPES partners operate on the basis of the DDDID approach: design,
develop, decide, implement and disseminate. A short list of substances,
to be studied in TAPES, was developed on the basis of their relevance
for the participating regions in TAPES and their representativeness for
groups of emerging substances (human pharmaceuticals, personal care
and life style products , pesticides, herbicides X-ray contrast media and
flame retardants). Secondly the DDDID was used to jointly decide on
the research issues and develop the research program.
Research on the short-listed emerging substances is carried out by the
different players in the water cycle and results are entered in the TAPES
decision support system (DSS). The DSS will use existing and newly
generated knowledge on sources of emerging substances (sources),
fate of emerging substances in the water cycle (pathways) and on
the potential impact on human health and on the aquatic environment
(receptors). The DSS will support problem-owners/end-users in their
decision-making process on where in the water cycle to most efficiently
and effectively address the problem of emerging substances.
Research on wastewater treatment Research is carried out on the occurrence and monitoring of emerging
substances in surface water and wastewater as well as the removal of
such substances in various wastewater treatment processes. Fourth step
technologies in wastewater treatment include amongst others: one step
total effluent polishing filter, removal of micro-pollutants through the
use of retention soil filters and dissolved air flotation (DAF) as pre-treat-
ment. The positive effects of the advanced treatment processes on the
water quality in the catchment areas are determined with the DWA wa-
ter quality model.

Research on drinking water productionResearch on the control of emerging substances in drinking water focusses
on both new analytical methods for the detection and quantification of
emerging substances (organic micro-pollutants) and on advanced re-
moval processes. The removal processes studied and improved are new
and innovative adsorbents, affinity adsorption, ion-exchange, advanced
oxidation processes
in combination with
activated carbon,
and membrane fil-
tration.
