Neglect plagues city's water filtration plants
Where the supply of water remains an incessant woe, plaguing the peace of locals in Karachi, it appears that even the measly quantity of water supplied to the residents is not fit for consumption.
Most of the water filtration plants of the Karachi Water and Sewerage Corporation (KW&SC) have been in disrepair in the city for many years. As a result, due to an inadequate amount of chlorine mixed in the water, many diseases, especially the deadly Naegleria, risk spreading among the local population.
Talking to The Express Tribune, General Secretary of the People's Labour Union Mohsin Raza disclosed that the Karachi Water and Sewerage Corporation (KW&SC) has nine filter plants, out of which only three are in working condition while the remaining six have been in disrepair for many years.
'As a result, forty percent less chlorine is being added to the water supply in Karachi. Hence, the water reaching all districts across the city is not disinfected and is causing various types of diseases among the citizens. Due to the negligence of the top officials of the Water Corporation, the required amount of chlorine cylinders has not been available for a long time. At some places, the staff adds the right amount of chlorine during the day but at night, chlorine is mixed in less quantity. Approximately, 645 million gallons of water is being supplied daily to the city. For this amount of water, 240 cylinders of chlorine should be available per month; however, only 150 cylinders are being supplied,' revealed Raza.
On the other hand, a spokesperson for the KW&SC while talking to The Express Tribune claimed that all nine filter plants with 32 chlorinators located across six different locations were functional. 'Chlorine tablets are being added to all water tankers going from the government hydrants of the Water Corporation. Apart from this, water samples are being analyzed on a regular basis in various laboratories of the Water Corporation,' claimed the spokesperson.
The on-ground reality, however, proves otherwise. Last year, the Health Department of Sindh obtained more than 50 water samples from different districts of the city before testing them at the Karachi Water and Sewerage Board (KWSB's) laboratory. The results confirmed the presence of several contaminants including pathogenic bacteria like Vibrio cholerae, E. coli and total coliforms, all of which culminated into a diarrhoea outbreak, which affected at least 20,000 children between April to September last year.
Similarly, Naegleria fowleri, which grows in contaminated water and is activated at 35 degrees Celsius, claimed four lives last year in Karachi. Just recently, a woman died of Naegleria in the Gulshan-e-Iqbal area of District East. Hence, it is expected that the amoeba will cause several casualties during the upcoming harsh summer months.
Cardiologist and health expert Dr Muhammad Akram Sultan revealed that if there is excess chlorine in water and it is used continuously, it will cause eye irritation, difficulty in breathing, coughing, vomiting, itching and stomach pain. "Water that has a high chlorine content and is used for a long time can also cause bladder and anal cancer," informed Dr Sultan.
While commenting on the precautionary measures needed to control the spread of Naegleria, the KW&SC spokesperson advised citizens to clean the overhead and underground tanks storing water on a monthly basis and avoid bathing in swimming pools, ponds and reservoirs with unchlorinated water. 'Apart from this, citizens should use one chlorine tablet in a 1,000-gallon water tank, which is enough for 15 days. People should use boiled or chlorinated water while performing ablution and bathing or for cleaning the nose in general,' emphasized the official.

Eight years on, Dr Ruth Pfau's legacy still touches thousands
Eight years after her passing, the legacy of Dr Ruth Pfau — the German-born physician who dedicated her life to eradicating leprosy in Pakistan — continues to inspire and serve thousands nationwide. Known as Pakistan's "Mother Teresa", Dr Pfau devoted more than five decades to the care of those shunned by society. Born on September 9, 1929, in Leipzig, Germany, she lived through World War II before moving to West Germany to study medicine at the University of Mainz. In 1960, en route to India, she was stranded in Karachi due to visa complications. The plight of leprosy patients she encountered here changed the course of her life. In 1963, she established Pakistan's first leprosy treatment centre on McLeod Road in Karachi, which evolved into the Marie Adelaide Leprosy Centre (MALC). Today, MALC operates 157 centres nationwide, offering treatment to more than 57,000 patients. Over the years, its services have expanded to maternal and child health, tuberculosis care, and support for the visually impaired and physically challenged. Colleagues recall that Dr Pfau's compassion extended beyond medical treatment. She would personally visit remote areas, sit and eat with lepers, and even inspect their kitchens to understand their economic conditions, often arranging financial help for housing or small businesses. "She never felt repulsed," said MALC CEO Maron Lobo, recalling how Dr Pfau would share tea and biscuits with the same hands that had dressed infected wounds. Her humility was legendary. She travelled in vans, walked to church, and eschewed official protocol. She was on the front lines during the 2005 earthquake, 2010 floods, and drought relief efforts in Balochistan. Her humanitarian work earned her several national honours, including the Hilal-e-Pakistan and Hilal-e-Imtiaz. Germany awarded her the BAMBI Award in 2012, where she reminded the audience: "At this moment, it's midnight in Pakistan, and many children will go to sleep hungry. Your world is not my world." Dr Pfau passed away on August 10, 2017, after a prolonged illness, becoming the first non-Muslim woman in Pakistan to be buried with state honours. Karachi's Civil Hospital now bears her name, and her former residence has been turned into a museum. For the patients she embraced when no one else would, and for the nation she chose as home, Dr Ruth Pfau remains a beacon of selfless service — a legacy that lives far beyond her years.

KP establishes modern food testing lab
PESHAWAR: The provincial government of Khyber Pakhtunkhwa established first state-of-the-art Food Testing Laboratory and Centre for Research at Hayatabad. Established at a cost of Rs 905 million, the facility is the first of its kind static food testing laboratory in the province, equipped with advanced machinery and modern testing capabilities. Officials stated that the laboratory will provide scientific analysis of food quality and detect adulteration using cutting-edge equipment. The lab encompasses specialized sections in food microbiology, food chemistry and nutritional analysis, pesticide residue detection, and mycotoxin analysis. It also includes capabilities for heavy metal analysis, dairy, meat, and edible oil testing, as well as sensory evaluation. Designed under one roof, the facility comprises eight dedicated sub-laboratories and is integrated with an online reporting system and a modern Management Information System (MIS). The lab has the capacity to test nearly 1,500 parameters across more than 100 food items and meets international ISO standards. It can detect harmful chemicals like aflatoxins and formalin, and microbial contaminants including salmonella, listeria, E. coli, and mold. Additionally, it allows testing for heavy metals in water and beverages, and performs comprehensive nutritional profiling including fat, protein, moisture, ash content, and calorific value. Speaking to the media on the occasion, the Chief Minister said the facility aligns with the vision of Imran Khan, under which the provincial government is committed to delivering quality public services and improving public health. He added that the lab is capable of identifying antibiotic residues in dairy and meat products and offers halal certification services. This includes verification of halal meat and detection of harmful or prohibited animal sources. Over 20 Food Authority offices across the province will serve as sample collection points, while a digital traceability system will allow easier public access and transparency. The Chief Minister lauded the timely completion of the project and directed authorities to ensure that the lab's systems are regularly updated and aligned with emerging technological trends. He stressed that food adulteration is a serious crime and those involved are enemies of public health, warning that no leniency will be shown in this regard. He said that only food items approved by this laboratory would be allowed for sale in the market, adding that other departments and government agencies would also benefit from the facility's services.

Rising mercury exposes gaps in hospital systems
Over the past few years, Khyber Pakhtunkhwa (K-P) has faced a dual climate crisis, with intermittent rainfall in some areas, and an unrelenting heatwave in others, leading to a surge in heatstroke and waterborne illnesses. Despite the worsening situation, authorities have yet to take meaningful preventative steps or establish dedicated heatwave response mechanisms in hospitals. From Peshawar to Dera Ismail Khan, Lakki Marwat to Mardan, temperatures are soaring dangerously. The Pakistan Meteorological Department has warned of more heat in the coming days, with temperatures expected to reach as high as 50 degrees Celsius in Peshawar; a level of heat that health experts believe is life-threatening, especially for children and the elderly. "There has been a clear rise in climate-related heat in K-P due to global climate change. Countries that have effectively managed climate challenges must be studied and their strategies should be localized. Infrastructure projects have led to the cutting down of thousands of trees, which were never replaced," noted Professor Dr Muhammad Nafees, Chairman of the Environmental Sciences Department at the University of Peshawar, who believed that unless swift action was taken, the province may see more heatwaves, floods, and natural disasters in the near future. On the other hand, medical staff in the city's major hospitals are now stretched thin. Dr Ahmad Khan, a medical officer at the emergency department of the Khyber Teaching Hospital revealed that they were receiving 10 to 15 heatstroke cases daily; a number that is steadily climbing. "Most patients are either elderly people or children. Along with heatstroke, we are also witnessing a spike in diarrhea and other gastrointestinal infections, which are directly linked to excessive heat," said Dr Ahmad who urged the public to stay indoors during peak heat hours and increase fluid intake. At the Lady Reading Hospital Peshawar, the province's largest public health facility, similar concerns were echoed. Muhammad Asim Khan, the hospital's spokesperson, told The Express Tribune that between 50 to 60 patients affected by heat-related illnesses were being admitted daily. However, there was no dedicated ward for dealing with such cases. "There is no designated facility or cooling center for heatwave patients. We are transferring them to the general emergency medical ward, where doctors and nurses are trying their best to stabilize them. But the volume of patients is increasing fast, and this approach is not sustainable," warned Dr Khan. As K-P struggles with climate unpredictability, the glaring lack of preparedness is putting lives at risk. With no emergency plan in place, no public awareness campaigns launched, and no infrastructure adapted for high temperatures, the province appears to be dangerously lagging in its response to one of the most predictable yet deadly effects of climate change. Experts warn that without long-term climate resilience policies including urban tree plantation, public cooling centers, awareness drives, and hospital preparedness, K-P could face even deadlier summers in the years ahead.
