The nitrate content of drinking water is rising at an alarming rate
in several regions of NATO countries and elsewhere in the world.
The increase is due to lack of proper sewage treatment, and
primarily to excess fertilizer application. Also, eutrophication in
several coastal areas is triggered by high nitrate concentrations.
The main purpose of this book is to integrate scientific knowledge
related to exposure assessment, health consequences and control of
nitrate contamination in water. The motivation is related to the
magnitude, the possible adverse health effects, and the high cost
of control ling nitrate contamination. Future research tasks are
defined by an interaction among hydro logists, toxicologists and
environmental engineers in an integrated framework for nitrate risk
management. The target readership of this book is a mix of
university colleagues, practitioners from both the private and
public sectors and advanced graduate students working with the
hydrological, health science or environmental engineering aspects
of nitrate contamination. The main conclusions include: 1. For risk
assessment purposes, knowledge and sufficiently accurate models are
available to predict nitrate load and its fate in water under
changes in land use. 2. Once agricultural exposure controls are
implemented, the response times in ground water may be so long as
to make controls unrealistic. 3. It is still unknown whether
agricultural best management practice is a compromise between
nitrate risk reduction and agricultural revenue. 4. The current
drinking water guidelines of 10 mg/L NOrN need not be changed.
