POLLUTION caused by a spillage from an overturned tanker carrying fertlizer has killed 100 fish in the River Witham, according to the Environment Agency.
The tanker spilled 3,000 litres of diluted ammonia into the water system when it overturned in Church Street, North Witham, last Tuesday.
The chemical has made its way into the River Witham where it has killed various species of fish in a stretch between Colsterworth and Little Ponton.
An Environment Agency spokesman said officers are monitoring the ammonia levels.
