The authorities have closed the Ankkuri beach in Lahti following detection of contaminated water in the area.

The authorities found E. coli bacteria in the water, resulting in the temporary closure of the beach to public, reported the national broadcaster Yle.

As the water sample taken on July 18 from the Ankkuri beach was found to have increased concentration of E. coli bacteria which may cause abdominal cramps and diarrhoea if ingested so the health authorities instructed people not to swim in the beach water.

The authorities also took new samples on Thursday from the beach area to re-examine the water condition and the results are expected to be ready on Saturday, said the Yle report.

“We will try to get the information as soon as possible,” the environmental health inspector of the area Sami Niemelä told Yle.

The authorities also have hoisted signal at the beach to limit contamination.

Earlier, on July 14, the authorities imposed a ban on swimming in Nallikari and Pateniemi beaches in Oulu, suspecting possible water contamination.

The ban, however, was withdrawn after examination of a sample was proven fee of any contamination and safe.

The water of Lappeenranta area was also suspected to have possibly contamination on July 13 after three million litres of wastewater reportedly entered into the Saimaa waterways recently.

Later it was proved that the water was not dangerous for swimming.
