Quality Control (or lack of it)

Risks from Polluted Rivers.   The UK is consistently ranked as one of the worst countries in Europe for water quality, over three quarters of our rivers fail to meet required health standards and face multiple threats. Water pollutants can cause disease or act as poisons. Bacteria and parasites in poorly treated sewage may enter drinking water supplies and cause digestive problems. Contaminated waters are linked to transmission of diseases such as, diarrhea, dysentery, hepatitis A, typhoid, and polio. Absent, inadequate, or poorly managed water and sanitation services expose individuals to preventable health risks. In Wales and England, 38% of fish health checks fail due to disease caused by pollution.
