This dataset was first added to MfE Data Service on 15 Apr 2019.

This dataset measures groundwater quality in New Zealand’s aquifers based on measurements made at monitored sites. Many factors influence the quality of our groundwater. Nitrogen, which occurs naturally in groundwater, can increase in concentrations due to agricultural and urban land use, and infrastructure such as waste treatment plants. High concentrations of nitrate-nitrogen in groundwater can affect human health and the quality of surrounding rivers and lakes that receive inflows from groundwater. Ammoniacal nitrogen can cause an undesirable smell that may make groundwater unsuitable for drinking water. Natural processes in groundwater can convert nitrate-nitrogen into ammoniacal nitrogen or other forms under some chemical conditions. Surplus phosphorus drains (leaches) into groundwater as dissolved reactive phosphorus. Too much nitrate-nitrogen, ammoniacal nitrogen, and phosphorus can lead to excessive plant and algae growth where groundwater flows into surface water. E. coli in groundwater is measured in colony forming units (cfu) and can indicate the presence of pathogens (disease-causing organisms) from animal or human faeces. The pathogens can cause illness for anyone who ingests them.

PM10 (particulate matter less than 10 micrometres in diameter) comprises solid and liquid particles in the air. PM10 can be inhaled and the largest particles in this size fraction are deposited in the upper airways, while the smaller ones can deposit deep in the lungs. Children, the elderly, and people with existing heart or lung problems have a higher risk of health effects from PM10 exposure. Health effects include decreased lung function or heart attack, and mortality.
We report on the modelled number of premature deaths for adults (30+ years), hospitalisations, and restricted activity days for people of all ages for years 2006 and 2016 only. The model only includes impacts that result from exposure to PM10 that comes from human activities.
We focus on PM10 from human activities because these sources can be managed, unlike PM from natural sources such as sea salt.
• Premature deaths are those, often preventable, occurring before a person reaches the age they could be expected to live to.
• Hospitalisations relate to those for respiratory and cardiac illnesses (not including cases leading to premature death).
• Restricted activity days occur when symptoms are sufficient to limit usual activities such as work or study. These days aren’t shared evenly across the population – people with asthma or other respiratory conditions would likely have more restricted activity days.
