Recreational Water
The water quality at more than 80 popular coastal, river and lake recreation sites in the region is monitored by Environment Bay of Plenty and Environment Waikato from November to March each year.
The waters are tested for bacteria and toxin forming algae species. If a recreational water site is found to be significantly contaminated, with risk to public health, Toi Te Ora Public Health Service informs the public by issuing a health warning and the local council erects warning signs.
If you swim in or drink contaminated water, you risk getting sick.
Water can be contaminated with toxic algae (blue-green algae/cyanobacteria) or animal faeces from rural or urban run-off.
What to look for
- If you notice the water in your local lake, river or beach is murky or has a musty smell, go somewhere else.
- Avoid swimming for up to 48 hours (two days) or until the water looks clear after heavy or prolonged rain.
Health risks
Toxic Algae
Toxic algae, also known as blue-green algae and cyanobacteria, are capable of producing toxins that are harmful to humans and animals, whether swallowed or exposed to skin during swimming, kayaking or water-skiing.
Symptoms include fever, headaches, dizziness, skin rashes, stomach cramps and aggravated hay fever and asthma and damage to the nervous system.

Sewer Overflows
In built up areas such as Tauranga Harbour there is a possibility of sewage discharge from the reticulated sewage system. This can lead to contaminated water. Should this occur, the local authority would advise the public that an unplanned sewer overflow has occurred and remedy the affected area.
For more information about sewer overflows, contact your local council.
Other contaminants
Water contaminated with animal and human faeces can lead to gastrointestinal illnesses (tummy bugs) such as Salmonella, Giardia, Campylobacter and Cryptosporidium.
People can also experience cold and flu-like symptoms and skin, eye and ear infections.
