We measure important substances of concern based on the chemical oxygen demand in water (see 303-2). The identification of areas with water stress occurred as part of the annual risk analysis. The classification of areas with water stress is based on the Verisk Maplecroft risk assessment. This currently affects our sites in Mexico, India, Singapore and Egypt.
