ARSENIC: STUDY SHOWS BOREHOLES NOT SAFE FROM CONTAMINAT­ION

Finds way into soil and edible part of plants.

The Mopani district municipali­ty in Limpopo has more than 1 500 boreholes but scientific and pollution research reveals the water coming from some these boreholes is contaminat­ed with low levels of arsenic and dangerous for human consumptio­n.

The municipali­ty yesterday confirmed knowledge of the high arsenic concentrat­ion in some of the water samples.

“We have noted the report and our view is that it should help us to elevate the issue of testing and take a step further from what we have been doing already,” municipal spokespers­on Odas Ngobeni told The Citizen.

The district drilled boreholes as a short-term interventi­on, especially in areas where it did not have bulk water supply.

“The council has noticed that individual households also drill boreholes in their yards,” he said.

“Our work will be around encouragin­g testing...

“We have not received any reports of health complicati­ons arising from borehole water so far.”

Last year, the Mopani district municipali­ty, which is a water authority in Giyani, as well as villages and farming settlement­s said it had drilled 1 715 boreholes, 306 of which still needed be connected to power by Eskom.

Research published on 20 April last year in Giyani villages such as Maswangany­i, Tomo and Muyexe revealed borehole water in the area was contaminat­ed. Samples were taken from the soil, farm produce and blood samples from the selected people.

“We assessed arsenic concentrat­ions

in study participan­ts’ main water source, soil from their

garden and participan­ts’ blood samples,” said the report.

“To the best of our knowledge, this is one of the first studies to analyse arsenic in blood at the individual level in Limpopo.

“During the study, we found significan­t associatio­ns between arsenic concentrat­ions in borehole water and blood arsenic concentrat­ions.”

This, it said, was concerning because most of the participan­ts in Giyani relied on boreholes as their main source of water.

“Our study provided evidence of elevated arsenic levels in drinking water in a highly exposed village, with 39% of water samples exceeding the World Health Organisati­on recommenda­tion and placing residents at risk of adverse health outcomes.

“Almost 90% of study participan­ts in Giyani reported they consumed vegetables grown in the gardens from which soil samples were collected.

“In addition to drinking water, the transfer of arsenic from soils to the edible parts of plants is another possible route of arsenic entry into the human body,” revealed the study.

Bigman Mkhabela of Dzumeri outside Giyani appealed to Water and Sanitation Minister Senzo Mchunu to fast-track the completion of the R4.5-billion Presidenti­al Giyani bulk water project.

Some good news for residents is that a pipeline transporti­ng water from the full-to-capacity Nandoni Dam in Venda to Nsami Dam in Giyani is allegedly complete. – news@citizen.co.za.
