Acid
mine drainage is the flow, or seepage, of polluted water from old mining areas.
Depending on the area, the water may contain toxic heavy metals and radioactive
particles. These are dangerous for people’s health, as well as plants and
animals. Acid mine drainage on the

3.2.1 Background
and Context
Grootvlei Proprietary Mines Limited is situated in the
district of Springs and falls within the Upper Vaal Water Management Area. The mine
has a metallurgical operation that extracts gold from underground mined ore.
The mine is at present operated by Aurora Gold East
3.2.2
Findings
The committee was informed that Aurora Mining has
taken over the management of the Grootvlei Mine. On the day of the visit, the
committee was briefed by the mining management on the status of the mine before
being taken to shaft 3, where the actual treatment of water occurs. The current
situation in the
The mine can no longer keep up with the discharge
standards as per their water use licence; and this is attributed to financial problems
that have overwhelmed the mine. The mine claimed it had not received the Department
of Mineral Resource’s (DMR) subsidy of R5 million since October 2009; and as a
result, the mine covers pumping costs out of working costs. It was brought to
the attention of the committee that the mine would lose the shaft within 5 days
if they stopped pumping. Furthermore, treatment has been non-continuous, for
example they would treat for few days and stopped the treatment. To date, the
mine has incurred over R100 million worth of water pumping costs, which could
have been used for other operations.
The discharging of untreated or partially treated
water is severely affecting the health of the neighbouring Ramsar wetland.
It is acknowledged that the Department of Water
Affairs is pursuing a criminal charge against the mine for the discharge of
partially treated water into the surrounding water course.

3.3.1
Background
and Context
The eMalahleni Mine Water Treatment Plant was built to
recover potable water from acid mine drainage from several mines in the
eMalahleni (Witbank) area. The plant was commissioned in September 2007 and has
been since operating successfully. It was designed to treat 25Ml/d of
3.3.2
Findings
The plant was found to be fully automatic, while human
intervention was required for chemical change-over, monitoring and maintenance.
The committee established that the plant is able to treat 20 – 25 Ml/day of
water dependent on pH and salt concentrations. Of the 25 Ml/day, 20 Ml/day is
sold to the eMalahleni
Anglo Coal SA
has approved building of houses for its employees through the production of
gypsum (solid waste - a by-product of the Emahlakleni purification process).
The committee found that the chief characteristic of the plant; was the use of
Reverse Osmosis to concentrate the water and produce supersaturated brine from
which the salts could be released in a simple precipitation process. The results of such a process were high
recovery of water, low operating costs and minimum waste. The plant has about
35 employees, each being actively involved in maintaining the plant operability.
A permanent training officer has been employed to ensure that there is no lapse
in skills amongst the staff and to deal with matters of high turnover as and
when such arises.
4. DAY TWO:
28 JULY 2010
4.1 SITE
VISIT TO
Lancaster Dam is a pollution control dam. All the
water that flows into it is not supposed to flow out onto the other side. The
main problem at the dam was radio active particles attached to the sediment.
4.1.1
Findings
When the committee visited the Lancaster Dam, it found
an area which appeared to have been filled with slimes that had recently been
mined. The dam was characterised (another word) by heavy equipment which made
it possible for the acidic slimes water and fine slimes to drain into the pond
and wetland below the dam. Downstream of
the dam, an orange pool of settled slimes, filled with acidic mine drainage
water was evident. Dry slimes were observed blowing throughout the Lancaster Dam
site.
The committee was concerned about the RDP houses that
had recently been established around the dam. The community drank and baptised
from acidic mine water. The population groups around the area were said to be
vulnerable, poor, uninformed and therefore needed to be ‘workshopped’ on a
regular basis on the dangers of the acid mine water. The main pollutants are
suspected to be acidic water and associated toxic metals arising from oxidation
of sulphides such as iron sulphide. Two children had recently drowned in two
pollution control dams and this was due to the dams not being fenced off. Enforcing
the fencing of mine dams should be undertaken by the Department of Mineral
Resources (DMR).

Rand Uranium is a 2 year old company. It has operated
the water treatment operations to maximum capacity. Despite exhaustive
engagement with government and proposal on possible solutions placed on the
table, it felt the delay by the state in responding did not help the situation.
The current system was such that the plant that they run was a temporary
measure. Acid water is neutralised, but there was no optimal lime utilization
due to insufficient mixing, high lime cost and there was no optimal sulphate

Rand Uranium stated that a consortium of mines had
submitted a proposal to DWA on 14 July 2010 on how, in its opinion, AMD could
be sustainably managed in the short to medium term. They await a response from
government.
4.3 VISITS
TO KRUGERSDORP GAME RESERVE HIPPO DAM
At the time of the visit, the water was decanting at
6ML/day from the neighbouring property. A sludge of radioactive and toxic
metals was observed. The hippos in the Hippo Dam were coated in sludge
containing heavy metals. There is anecdotal evidence that at least one of the
hippos is now partially sighted due to the pollution.

LOCAL MUNICIPALITY COUNCIL CHAMBERS
4.4.1 Briefing
on Water Provision in Madibeng
The households of about 102, 060 in Madibeng Local
Municipality (
What remains a challenge in this municipality is the
rapid growth in development which has led to the demand of water exceeding
supply. The sanitation system comprises of an aging infrastructure and thus
poses operational and maintenance challenges. The Water Purification Plant that
supplies Brits and environs also requires an expansion by an additional 40-mega
litres per day and it is envisaged to be completed in phases. The municipality
had requested the Department of Water Affairs to take over the implementation
of the RBIG project (upgrading of WWTP). An amount of about R20 million has
been made available for 2010/11 for the implementation of the project. Magalies
Water was recommended to manage the project.
5. DAY THREE
5.1 SITE
VISIT TO MADIBENG WWTW (Waste Water Treatment Works)
The municipality has a newly upgraded plant which
processes 6Ml/day and the old one which used to process 8Ml/day. The old plant
has deteriorated due to negligence and the principal consultant allegedly ill
advised the Municipality. The sludge lagoons were not working to capacity, and
were at the point of breaking and had not been emptied for the past 30 years.
Some of the problems associated with the plant which were identified were,
amongst others, non compliance to standards, staffing levels acutely
inadequate, no maintenance plans and effluent monitoring needed to be
increased. None of the pump stations were working, and of the average of
12Ml/day that should come to the plant, only 3Ml/day were treated and the rest
(about 9Ml/day) went to the streets.
The municipality was however, committed to urgently
source funding for the refurbishment of Water and Sanitation Infrastructure,
recruitment of critical positions in the Water and Sanitation department.
5.2 BRIEFING:
ADDRESSING THE CHALLENGES OF WWTW AS IT ADDS TO THE EUTROPHICATION OF THE
HARTBEESPOORT DAM
The Hartbeespoort Dam is the most significant dam in
the economic hub of the Crocodile West Marico Water Management Area for
domestic, agricultural, industrial and recreational purposes. The dam is in a hyper-eutrophic
state, meaning it is trapped with excessive nutrients. For many years, the Crocodile
River has been pouring an increasing load of phosphorus into Hartbeespoort Dam.
This had led to high levels of nutrients and eutrophication of the water.
It was brought to the attention of the committee that
about 9 wastewater treatment works discharge their 620 million liters per day
of purified effluent into the Crocodile River, with very high loads of waste
water effluents. These intensify the occurrence of blue-green algae or
cyanobacteria. There is however, a remediation programme of the Hartbeespoort
Dam in place. It focuses on management of phosphate through natural uptake in a
food chain and re-establishing a biological balance within the dam waters using
among other things, floating islands and removal of certain fish types.
The Hartbeespoort Dam is an invaluable water resource
with a major economy around recreation and tourism attractions. People and
business are moving into the area, thus contributing to its economic growth.
The remediation programme has been in existence for
almost 5 years but a determination of its effectiveness has not been
undertaken. The project manager was able to provide outcomes achieved, but
there is no analysis of how any particular outcomes are affecting the actual
health of the dam.
In consultation with stakeholders from local resident
organisations and environmental organisations, there was a mixed response to
the success of the remediation programme. There was general appreciation that
something was being done to remediate the dam. There was a dominant feeling
that the managers of the remediation programme were not sufficiently including
local organisations in consultations, especially considering that many
organisations financially support efforts to remediate the dam themselves. It is noted that a number of people donate
their skills free of charge to the remediation of the dam.

RECOMMENDATIONS
·
The Department of Water
Affairs (DWA) should produce a business plan on how it intends to tackle the
·
DWA should engage
with DMR about ensuring the safety of mining dams.
·
DWA should offer
full cooperation with regards to any investigation by the NPA to prosecute the
owners of Grootvlei mine following the criminal charge laid by the department.
·
DWA should engage
with DMR about ensuring the implementation of the Regional Mine Closure
Strategy.
·
DWA should urgently
increase its response to the current decant of AMD on the West Rand, noting
that due to the upcoming rainy season, it is highly likely that the decant will
increase.
·
DWA should issue a
directive to responsible mines in the West Rand for the remediation of the Hippo
Dam in the Krugersdorp Game Reserve.
·
DWA should ensure
that skilled staff of the department constantly monitors the remediation of the
Brits WWTW. DWA should ensure strict timelines on the complete refurbishment of
the plant.
·
DWA should complete
a financial and skills audit of the Hartbeespoort Dam remediation programme now
that it has been in existence for almost 5 years to determine whether it is
effective, and whether the protocols and methodologies used to measure the
state of health of the dam are adequate.
·
DWA should ensure
that the Remediation Programme improves its efforts to engage with local
stakeholders.
·
DWA needs to
clarify the role of Rand Water as the implementing agent of the remediation
project in relation to the involvement of local officials of DWA. In addition
it should be clarified who has specific signing powers for services procured.
·
DWA should ensure
that there is a wider system implemented to monitor the health of freshwater
dams and reservoirs across South Africa.
