Of the samples tested, 84% were above 1 mg\/L \u2013 the level associated with an increased risk of bowel cancer, and 16% of samples were above 5 mg\/L \u2013 the level associated with an increased risk of preterm birth.<\/p>\n\n<p><strong>Greenpeace freshwater campaigner Will Appelbe<\/strong> says, \u201cWe\u2019re encouraging everyone who is on a private bore, or is concerned about the safety of their drinking water, to come down to Lumsden tomorrow and get their water tested for nitrate.\u201d<\/p>\n\n<p>\u201cToday we\u2019ve spoken to parents, grandparents, and families who are on the frontlines of Southland\u2019s nitrate crisis. Environment Southland\u2019s own reports have identified that this is a growing issue for the region. And the trends show that nitrate contamination will likely get worse across 71% of groundwater monitoring sites.<\/p>\n\n<p>\u201cThe cause of this nitrate contamination is&nbsp; the intensive dairy industry, and its overuse of synthetic nitrogen fertiliser. Rural New Zealand is being poisoned by dirty dairy pollution, which means the&nbsp; agricultural sector must be regulated and move towards&nbsp; ecological, regenerative farming practices. This needs to start now.\u201d<\/p>\n\n<p>Greenpeace says that while the town supply in \u014ctautau is low in nitrate contamination, it\u2019s still higher than the nitrate level for most people in Aotearoa.<\/p>\n\n<p>\u201c80% of New Zealanders are drinking water at levels of nitrate under 1 mg\/L. That\u2019s important because long-term exposure to levels of nitrate as low as 1 mg\/L is associated with an increased risk of bowel cancer.\u201d<\/p>\n\n<p>The organisation will be at the Lumsden Memorial Hall from 10am-3pm tomorrow. It is asking the public to bring in 200 mL of their drinking water in a clean container to get it tested.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Greenpeace says that while \u014ctautau
