Hon DAVID PARKER: Well, in respect of the effect on drinking-water sources, that's an issue that falls to the Associate Minister for the Environment, Minister Allan. In respect of whether that breaches standards for consumption of drinking water, that's a matter for the Associate Minister of Health. In respect of the broader issues as to whether there are environmental consequences from intensive dairying in parts of the country that still need to improve, then, yes, I agree with that.
