At times, water can have an unpleasant odour, taste, or appearance. These aesthetic characteristics usually do not pose a public health threat and, in most cases, they do not last long. However, a sudden change in colour, taste or odour of your tap water could indicate changing water characteristics, if you notice taste and odour, flush the cold water tap nearest the water meter. If the taste and odour persist, please contact the Town of Newmarket at 905-895-5193.
