1 00:00:00,200 --> 00:00:03,760 Speaker 1: The Water Services Authority has been notified of increase levels 2 00:00:03,760 --> 00:00:06,720 Speaker 1: of arsenic in the Waikato River, which feeds into the 3 00:00:06,720 --> 00:00:09,480 Speaker 1: Auckland and Hamilton water supply. The agency says there is 4 00:00:09,640 --> 00:00:14,080 Speaker 1: no health risk in drinking the water, but the maximum 5 00:00:14,200 --> 00:00:18,160 Speaker 1: acceptable value for arsenic is zero point zero one milligrams elater, 6 00:00:18,360 --> 00:00:21,480 Speaker 1: an incredibly low amount apparently, but they have seen levels 7 00:00:21,480 --> 00:00:24,560 Speaker 1: between zero points zero one one milligram and zero point 8 00:00:24,880 --> 00:00:29,280 Speaker 1: zero one five milligrams, which is quote marginally above the 9 00:00:29,400 --> 00:00:33,080 Speaker 1: acceptable value for drinking water. Steve Taylor is the head 10 00:00:33,120 --> 00:00:36,840 Speaker 1: of operations at Water Services Authority, needs with us this morning. Steve, 11 00:00:36,840 --> 00:00:39,040 Speaker 1: good morning, welcome to the show. Have you had any 12 00:00:39,320 --> 00:00:42,440 Speaker 1: new results in overnight since since you last spoke? 13 00:00:43,560 --> 00:00:45,440 Speaker 2: No, I haven't. There's been a number of samples that 14 00:00:45,479 --> 00:00:48,400 Speaker 2: were taken, yes, just to can fill what those levels 15 00:00:48,440 --> 00:00:50,839 Speaker 2: are in fact that there's been any decrease as a 16 00:00:50,840 --> 00:00:53,960 Speaker 2: result of the actions that water Care has taken over 17 00:00:54,000 --> 00:00:58,040 Speaker 2: the last few hours. That are expecting those results this morning? 18 00:00:58,520 --> 00:00:59,480 Speaker 1: What time this morning? 19 00:01:01,120 --> 00:01:04,319 Speaker 2: Well, I have to check of the laboratory, but I 20 00:01:04,440 --> 00:01:08,440 Speaker 2: understand they've been prioritized with haste, so we'd expect setos 21 00:01:08,520 --> 00:01:09,440 Speaker 2: sons are available. 22 00:01:09,959 --> 00:01:12,759 Speaker 1: How can you say that it's safe to drink even 23 00:01:12,800 --> 00:01:16,240 Speaker 1: though it's above the acceptable value for drinking? 24 00:01:17,480 --> 00:01:21,520 Speaker 2: Yes, acceptable value for a drinking water is designed for 25 00:01:21,680 --> 00:01:24,440 Speaker 2: long term exposure. So in other words, that someone was 26 00:01:24,560 --> 00:01:29,640 Speaker 2: drinking amount of water over forty fifty years, and we 27 00:01:29,760 --> 00:01:33,000 Speaker 2: might expect to see some health effects. That's up here 28 00:01:33,280 --> 00:01:37,720 Speaker 2: after forty or fifty years. So prolonged extensive drinking at 29 00:01:37,840 --> 00:01:41,720 Speaker 2: levels above and makes them acceptable value. What we've got 30 00:01:41,720 --> 00:01:46,119 Speaker 2: here is a marginal increase above acceptable value that would 31 00:01:46,160 --> 00:01:50,600 Speaker 2: expect to see reduced overcoming days. 32 00:01:51,080 --> 00:01:53,480 Speaker 1: When did you so, how long is it? When did 33 00:01:53,480 --> 00:01:54,960 Speaker 1: you first find out about the result. 34 00:01:55,960 --> 00:02:01,320 Speaker 2: So we found out about these results yesterday yesterday morning. 35 00:02:02,320 --> 00:02:06,160 Speaker 2: Bear in mind that the Whitecatta River naturally has underlying 36 00:02:06,240 --> 00:02:10,040 Speaker 2: levels of arsenic inner and the treatment plants for both 37 00:02:10,120 --> 00:02:14,120 Speaker 2: Auckland City and Hamilton City do that arsenic. So they 38 00:02:14,200 --> 00:02:17,239 Speaker 2: removed the arsenic before it's put into the drinking water. 39 00:02:17,280 --> 00:02:20,400 Speaker 2: That's an important part of their treatment. And we know 40 00:02:20,600 --> 00:02:26,600 Speaker 2: from what these activities. Immediately after receiving these notifications, they 41 00:02:26,600 --> 00:02:31,080 Speaker 2: are changing their treatment process to extally ensure the increased 42 00:02:31,160 --> 00:02:33,519 Speaker 2: levels of the arsenic areagely removed from the water. 43 00:02:34,240 --> 00:02:37,000 Speaker 1: So did both you as a regulator and water Care 44 00:02:37,040 --> 00:02:39,000 Speaker 1: both only found out about this yesterday. 45 00:02:40,840 --> 00:02:43,400 Speaker 2: Yes, that's great, but because Hamilton. 46 00:02:43,080 --> 00:02:46,079 Speaker 1: City Council said that they testing during a stage of 47 00:02:46,120 --> 00:02:49,280 Speaker 1: the treatment process on the nineteenth and twentieth of November 48 00:02:49,440 --> 00:02:51,919 Speaker 1: recorded results that were elevated. 49 00:02:53,600 --> 00:02:57,880 Speaker 2: Yes, so we're aware that results within the river itself, 50 00:02:58,000 --> 00:03:01,080 Speaker 2: so this is before the point of treatment and vary. 51 00:03:02,320 --> 00:03:08,600 Speaker 2: So we were notified. I'm just not data today Thursday, 52 00:03:08,680 --> 00:03:14,360 Speaker 2: on Thursday morning at the levels within the point network 53 00:03:14,360 --> 00:03:17,960 Speaker 2: in Hamilton or above the acceptable value and at that 54 00:03:18,000 --> 00:03:20,480 Speaker 2: point that's when we've requested ongoing action. 55 00:03:22,040 --> 00:03:25,560 Speaker 1: You've so you found out actually a week ago that 56 00:03:25,639 --> 00:03:31,440 Speaker 1: there were elevated levels of arsenic in the river and. 57 00:03:31,320 --> 00:03:37,200 Speaker 2: You are saying that we were notified on the twenty seventh, 58 00:03:37,320 --> 00:03:40,080 Speaker 2: so that's the last night. 59 00:03:40,200 --> 00:03:46,920 Speaker 3: Sorry, So why is it so Hamilton City Council noted 60 00:03:46,960 --> 00:03:49,880 Speaker 3: that they had elevated levels on the nineteenth and twentieth 61 00:03:49,920 --> 00:03:50,560 Speaker 3: of November. 62 00:03:51,120 --> 00:03:53,880 Speaker 1: That's a week ago, right, So why weren't you told? 63 00:03:55,680 --> 00:03:58,280 Speaker 2: I can't comment on that. We'd expect to be notified 64 00:03:58,320 --> 00:04:04,920 Speaker 2: with any increase and levels above the math and there's 65 00:04:04,960 --> 00:04:07,360 Speaker 2: a requirement that we are notified of those results. 66 00:04:07,840 --> 00:04:10,440 Speaker 1: Okay, So if you weren't, what do you do about it? 67 00:04:11,560 --> 00:04:13,960 Speaker 2: And so I'll be flying up with Hamilton to check 68 00:04:14,040 --> 00:04:17,440 Speaker 2: what the results were the tilling of those results. Again, 69 00:04:17,480 --> 00:04:19,440 Speaker 2: if it's a spike in the source water, we should 70 00:04:19,440 --> 00:04:22,880 Speaker 2: have been notified about that. It's possible that that was 71 00:04:23,720 --> 00:04:25,680 Speaker 2: an issue that's been managed through as part of their 72 00:04:25,680 --> 00:04:30,520 Speaker 2: treatment process. But again it's important that we do receive 73 00:04:30,640 --> 00:04:34,000 Speaker 2: notice of these results so that we can ensure that 74 00:04:34,040 --> 00:04:36,080 Speaker 2: supplies are actually taking the appropriate action. 75 00:04:36,440 --> 00:04:39,240 Speaker 1: When you say how when you say water Care is 76 00:04:39,320 --> 00:04:42,240 Speaker 1: changing or rejigging the way that it processes the water, 77 00:04:42,520 --> 00:04:45,760 Speaker 1: what exactly does that mean and why aren't we doing 78 00:04:45,920 --> 00:04:47,040 Speaker 1: that already? 79 00:04:48,200 --> 00:04:50,120 Speaker 2: Yeah? So what it Care has got the ability as 80 00:04:50,200 --> 00:04:53,719 Speaker 2: part of its natural treatment of water to turn it 81 00:04:53,760 --> 00:04:57,200 Speaker 2: on different treatment plants as part of its day to 82 00:04:57,279 --> 00:05:01,440 Speaker 2: day operations, So it has the ability it can reduce 83 00:05:01,520 --> 00:05:05,240 Speaker 2: the intake from its white cat A treatment and increase 84 00:05:06,560 --> 00:05:09,560 Speaker 2: the amount of that's being supplied from its dams and 85 00:05:09,600 --> 00:05:13,160 Speaker 2: other sources. So it's switched out process on And what 86 00:05:13,200 --> 00:05:15,680 Speaker 2: it means is the water that is coming through the 87 00:05:15,680 --> 00:05:19,000 Speaker 2: way Kato treatment plan has slowed down, which means the 88 00:05:19,040 --> 00:05:21,920 Speaker 2: ability for those folds to remove the arts increase of 89 00:05:22,120 --> 00:05:24,360 Speaker 2: so the slow the water moves through those filters, the 90 00:05:24,480 --> 00:05:26,160 Speaker 2: more efficient the process is. 91 00:05:26,320 --> 00:05:28,960 Speaker 1: All right, Steve, you can guarantee as one hundred percent 92 00:05:28,960 --> 00:05:31,279 Speaker 1: there will be no ill health effects from this, nothing 93 00:05:31,279 --> 00:05:33,760 Speaker 1: for pregnant women, nothing for the elderly, nothing like that. 94 00:05:35,160 --> 00:05:37,719 Speaker 2: So we're confident that these levels are safe to drink, 95 00:05:38,320 --> 00:05:41,320 Speaker 2: but would expect both Hamilton and water Care to be 96 00:05:41,839 --> 00:05:45,200 Speaker 2: acting proactively just to reduce any risk. 97 00:05:45,560 --> 00:05:47,480 Speaker 1: Steve, thanks for your time this morning.
