Most UK dairy farms ignoring pollution rules as manure spews into rivers

Exclusive: 80% of Welsh dairy farms inspected, 69% of English ones, 60% in Scotland and 50% in Northern Ireland breaching regulations

The majority of UK dairy farms are breaking pollution rules, with vast amounts of cow manure being spilled into rivers.

When animal waste enters the river, it causes a buildup of the nutrients found in the effluent, such as nitrates and phosphates. These cause algal blooms, which deplete the waterway of oxygen and block sunlight, choking fish and other aquatic life.
