ADA WATER POSES NO THREAT |

There have been complaints from residents of Keseve-Ada of a sudden salty taste in their pipe-borne water, which have led to concerns about the health of consumers.
The “salty taste” in the water is caused when sea-water flows upstream to the location of the Ghana Water Company treatment plant, as a result of high tides.
“But there's no risk to consumers because AVRL treats and filters the raw water; the salinity is also monitored to ensure that approved standards are met,” according to Mr. Evans Balaara, AVRL's Water Quality and Laboratory Manager.
The Ghana Raw Water Criteria and Guidelines require that the amount of chloride (salt) in pipe-borne water be within a range of 200 to 600 milligrammes per litre (mg/litre).
Salt content in raw water samples taken at Keseve-Ada in mid-September was 402.5 mg/litre. After treatment this was reduced to 378.0 mg/litre, which is within the allowable range.
“This level of chloride would give the water a salty taste but it has no adverse health effect,” Mr. Evans Balaara said.
Additionally, this unusual situation occurs only occasionally. The last such occurrence was in 2003. Under usual circumstances, salt content per litre does not exceed 250 mg. In the meantime, AVRL continues to monitor the situation.
