Warming winters lead to more nitrate pollution in the drinking water near farms

When pollution gets bad enough in the rivers supplying Iowa's largest city with drinking water, it costs Des Moines around $16,000 a day to run a special system to filter out dangerous nitrates. It's a fact of life in the agriculture-dependent state—and climate change is making the water quality problem even worse.

Pollution aux nitrates: des syndicats dénoncent la « mutation forcée » d’une fonctionnaire

Des syndicats de la Direction régionale de l’Environnement (DREAL) de Bretagne ont dénoncé jeudi la « mutation forcée » d’une collègue chargée du dossier des nitrates, alors que la région souffre d’une pollution des eaux liée à l’agriculture intensive.

Last month Greenpeace stuck a dead eye on Rakaia's big fish and the locals cried "vandalism!"

Well, Rakaia held it's famous fishing competition over the weekend. Four hundred people entered, and not a single fish was caught. It's the first time that's happened in the 40 years that the competition's been running.

The problem is mainly dairy, of course. Oversized water take permits reduce water flow, which increases water temperature, which kills fish. Gotta feed those pivot irrigators. Cram the fields with cows and the resulting nitrate pollution leaching into most of our waterways does the rest.

They. Didn't. Catch. One. Fish!

Canterbury fishing comp gives out $60K in prizes despite no fish caught

For the first time in 40 years, no fish were weighed in at the Rakaia Fishing Competition due to woefully low numbers of salmon in the river. But ...

Southland has a drinking water crisis on its hands, caused by dairy industry pollution

Only 1% of domestic wells mapped were in areas predicted to have nitrate concentrations below 1mg/L and almost half (49%) were in areas predicted to have concentrations within a range of 3.5 to 8.5mg/L, with a further 5% predicted to exceed 8.5mg/L, with some of these above 11.3mg/L.

The maximum allowable nitrate in drinking water is 11.3mg/L, but the National College of Midwives has warned pregnant women about levels exceeding 5mg/L risking preterm birth and low birthweights and public health academics have said levels below this may be a concern, including as a cause of colorectal cancer.

Ms Prickett said any level above 3.5mg/L was indicative of “serious degradation of environmental health let alone public health”.
