Lake Rotorua debate

Document

In 1969 a visiting US sanitary engineer, T. P. Moellendorf, caused controversy when he compared Lake Rotorua to an unflushed toilet. Raw sewage was being discharged into the lake, and rapidly spreading weeds made some parts unusable. Although the city of Rotorua soon began treating sewage, there is a still a problem of excess nutrients from the surrounding farmland. In 2006 the state of the lake was much worse than in 1969.
