The Zambia Environmental Management Agency (ZEMA) has completed its investigation on seven mining firms on the Copperbelt over last week's pollution of the Kafue River.

ZEMA Northern Region Manager Gift Sikaundi says the investigations team finished collecting samples from all suspicious sites and handed them over to three separate laboratories.

"We have handed over the samples to the Water Resources Management Authority laboratory in Lusaka, the Alfred Knight laboratory in Kitwe and the Nkana Water and Sewerage Company laboratory in Kitwe. We expect the results after seven days," said Mr Sikaundi during an interview at his Ndola office.

He has disclosed that during the investigation, ZEMA inspectors collected samples from various dams, reservoirs and streams in Chingola and Mufulira.

On Thursday last week, ZEMA launched investigations against the seven mining firms after sulphate was detected in the Kafue River the source of water supply to Kitwe, Kalulushi and Chambeshi.

The seven mining firms all discharge water into the Mwambashi stream which eventually ends up in the Kafue river.

The companies being investigated are Konkola Copper Mines, Mopani Copper Mines, NFC Africa Mining, Chambeshi Copper Smelter, Chambeshi Metals, Sino Metals and Bollore Africa Mining.

The investigations team took four days to collect samples from all water reservoirs and dams where the firms dispose off their effluents.

The discovery of the sulphate on Monday last week forced Nkana Water and Sewerage Company to shutdown its water supply to its customers for two days, leaving Kitwe's over 500,000 residents without clean running water.

The supply was only restored after the utility neutralised the sulphate.

The pollution is believed to have happened in the Mwambashi stream in Chingola District.

The investigators further believe that the contaminated water flowed from the Mwambashi stream to the Kafue river where Nkana Water and Sewerage Company detected it.

Zambia Investigates Seven Major Mining Firms For Pollution

Zambia's environment watchdog has launched investigations on seven major multi-national mining firms following the polluting of Kafue river, the source of drinking water for the country's second largest city Kitwe.

Four of the seven companies being investigated are Chinese owned.

The largest mining investor in Zambia, Konkola Copper Mines (KCM) a subsidiary of London-listed Vedanta Resources PLC, Mopani Copper Mines a subsidiary of the Anglo-Swiss multi-national Glencore, Chinese owned NFC Africa Mining PLC, Chambeshi Metals, Chambeshi Copper Smelter, Sino Metals and Bollore Mining Limited are all under investigation.

On Monday, the Kafue river and its tributary Mwambashi were polluted with sulphate which forced the Nkana Water and Sewerage Company to shut down its operations, leaving the  over 500,000 residents of Kitwe without running water for 48 hours.

On Thursday, the Zambia Environmental Management Agency (ZEMA) launched the investigations on the seven mining firms because they all discharge their effluent into the Mwambashi stream which was the source of the pollution.

In the past three days, ZEMA inspectors have been testing water at Muntimpa Tailings Dam in the mining town of Chingola where KCM discharges its effluent before it flows into the Mwambashi stream which eventually offloads its water into the Kafue river.

The lead investigator in the exercise Gift Sikaundi says results of the tests carried out at Muntimpa Tailings Dam are expected to be made public next week on Monday.

"We have collected samples from Muntimpa Tailings Dam and we are analysing them in the laboratory right now. We are hoping to get a conclusive result on Monday," said Mr Sikaundi who is also ZEMA's Manager for the Northern Region of Zambia.

He also revealed that the institution wrote letters to all the seven multinational companies demanding that they hand over their test results from their respective discharge for the past 30 days but only four of them have complied.

"So far, only KCM, NFC Africa Mining, Chambeshi Copper Smelter and Mopani Copper Mines have submitted their reports. The remaining three didn't submit by yesterday's deadline. Despite that, we will conduct our own investigation and catch the firm which polluted the water."

Zambia's water regulator the Water Resources Management Authority (WRMA) has also joined the probe.

Inspectors from WRMA today joined their counterparts from ZEMA during their investigations in the mining town of Chingola.

ZEMA is a government agency under the Ministry of Environment and Natural Resources while WAMA is under the Ministry of Energy and Water Development.

Of the seven being investigated, KCM has more allegations of pollution than the remaining six.

In the past, the Indian-owned mining giant has been tried, convicted and fined by the Zambian courts for pollution.

The firm and its Indian parent company Vedanta Resources PLC are currently sued in London for polluting over 1,800 Zambian citizens.

And a Kitwe-based environmental activist Lovemore Muma says ZEMA needs to be more proactive when dealing with pollution cases in the mining sector.

"The current case where ZEMA is investigating the pollution of the Kafue river shows that ZEMA is reactive and not proactive. Imagine if Nkana Water and Sewerage Company did not detect the sulphate in the river, was ZEMA going to detect it? What is happening to other rivers which are not tapped by water utilities? This is worrying," said Mr Muma who is the Executive Director of The Earth Organisation, a civil society organisation which campaigns for the environment.

He further says ZEMA must be strengthened by being transformed into an authority which will have powers to prosecute environmental offenders as opposed to just investigating and publishing its findings.

This case has received considerable media attention in the country.
