DOE detects STP blower valve fault at manufacturing factory amid Sitiawan river pollution probe

The Department of Environment (DOE) is investigating alleged river pollution after dead fish and crabs were found in Sungai Sitiawan.

Industrial effluent samples were collected from a manufacturing factory's final discharge point for comparison with river water samples.

A malfunction at the factory's Sewage Treatment Plant was identified, though sewage samples couldn't be taken due to low flow.

The DOE conducted in-situ testing and is awaiting analysis results from the Chemistry Department Malaysia to determine potential legal action and will continue monitoring the situation.

IPOH, Sept 3 — The Department of Environment (DOE) has collected industrial effluent samples from a manufacturing factory as part of its investigation into alleged river pollution after fish and crabs were found dead in Sungai Sitiawan.

The department said the samples were taken at the premises’ final discharge point to allow investigators to compare them with water samples collected from the river.

“Industrial effluent samples were taken at the final discharge point of the premises. This is to enable the matching of samples from the premises with the river water samples,” it said in a statement today.

During an inspection of the factory, the DOE said its investigation team identified a malfunction involving a blower valve at the factory’s Sewage Treatment Plant (STP).

However, sewage effluent samples could not be collected as the flow rate at the time was very low, at 0.583 cubic metres per hour, it said.

The DOE said it received information about dead fish being discovered in Sungai Sitiawan at 9.57am on Aug 30.

Investigations were subsequently carried out at three locations — Wak Dol Jetty, D’ Chalet accommodation and Tanjung Uda River Resort.

“At the complaint locations, several fish and other aquatic life were found dead and floating on the surface,” the DOE said.

It said small fish were found at Wak Dol Jetty, while larger fish were found dead at the D’ Chalet location.

The department also conducted in-situ testing and collected water samples from all three locations for further analysis by the Chemistry Department Malaysia.

The in-situ tests recorded dissolved oxygen readings of 5.86mg/L at Wak Dol Jetty, 3.79mg/L at D’ Chalet and 1.59mg/L at Tanjung Uda River Resort.

The DOE said it would await the analysis of the river water and industrial effluent samples by the Chemistry Department Malaysia before determining further action.

“Legal action will follow depending on the results of the analysis of the samples by the Chemistry Department Malaysia,” it said.

The department added that it would continue monitoring the situation and conduct enforcement inspections on nearby premises that could potentially be responsible for polluting the river.

在实兆远河发现死鱼和死蟹后，环境部正在调查涉嫌河流污染事件。

从制造工厂的最终排放点采集工业废水样品，与河水样品进行比较。

经查明，该工厂的污水处理厂发生故障，但由于流量低，无法采集污水样本。

美国能源部已进行现场测试，目前正在等待马来西亚化学部门的分析结果，以确定可能采取的法律行动，并将继续监测事态发展。

怡保，9月3日讯——环境部已从一家制造厂采集工业废水样本，作为对涉嫌污染河流事件的调查的一部分。此前，有人在实兆远河发现死鱼和死蟹。

该部门表示，这些样本是在该场所的最终排放点采集的，以便调查人员能够将其与从河中采集的水样进行比较。

“我们在厂区的最终排放点采集了工业废水样本。这是为了将厂区内的样本与河水样本进行比对，”该机构今天在一份声明中表示。

在对该工厂进行检查时，能源部表示，其调查小组发现该工厂污水处理厂 (STP) 的一个鼓风机阀门出现故障。

报告称，由于当时的流量非常低，每小时只有 0.583 立方米，因此无法收集污水排放样本。

环境部表示，8月30日上午9点57分，他们收到消息称在实兆远河发现了死鱼。

随后对三个地点进行了调查——瓦克多尔码头、D' Chalet 住宿和丹绒乌达河度假村。

“在投诉地点，发现多条鱼类和其他水生生物死亡并漂浮在水面上，”美国能源部表示。

报告称，在瓦克多码头发现了小鱼，而在D' Chalet地点发现了大鱼的尸体。

该部门还进行了现场测试，并从这三个地点采集了水样，供马来西亚化学部门进一步分析。

现场测试记录显示，Wak Dol Jetty 的溶解氧读数为 5.86mg/L，D' Chalet 的溶解氧读数为 3.79mg/L，Tanjung Uda River Resort 的溶解氧读数为 1.59mg/L。

能源部表示，将等待马来西亚化学部门对河水和工业废水样本的分析结果，然后再决定采取进一步行动。

“我们将根据马来西亚化学部门对样品的分析结果采取法律行动，”声明中写道。

该部门补充说，将继续监测情况，并对可能造成河流污染的附近场所进行执法检查。
