Heavy rainfall and landslides in Kenya have forced nearly 200,000 people from their homes and killed more than 100.

The Lead
Researchers in Sri Lanka are investigating why a growing number of people are suffering from cases of “chronic kidney disease of unknown etiology,” known as CKDu, Al Jazeera reports. In regional hotspots across the country, as many as 23 percent of residents have been diagnosed with the affliction, which has no obvious causes.
It is likely, however, that toxic agrochemicals are playing a role, scientists hypothesize. They have found geographic links between disease hotspots and irrigation water, and it is mainly men — who tend fields of rice paddies and other crops, and rely on aquaculture and fishing — who are experiencing symptoms of back pain, swelling, and aches.
In farming communities, those who are able switch from drinking groundwater to filtered water, though few have the financial means to do so consistently. Others are still using groundwater to cook and clean. An economic downturn has also forced community members to ignore their own health, taking pain-killers while continuing to work in polluted conditions.
Meanwhile, chronic dehydration amid rising temperatures across Sri Lanka is worsening poor health. Among fishermen, the tradition of drinking liquor to quell seasickness compounds the negative health effects.
Some families are opting to boil their groundwater, which experts say helps to remove bacteria but not toxic concentrations of pollutants, which include calcium and fluoride. More education is needed, scientists urge, to institute healthier practices, though they acknowledge that it is difficult to affect lifestyle changes without financial freedom.
This Week’s Top Water Stories, Told In Numbers

Percent of voters in Arizona “who believe the state is running out of water,” according to a survey by Noble Predictive Insights, the New York Times reports. This anxiety has prompted Democrats to seize on water rights and access as major talking points ahead of the 2024 U.S. elections, particularly in small and rural counties where groundwater pumping to irrigate crops has in some instances caused entire towns to sink some five or more feet. For those whose wells are going dry and have witnessed private landowners — including foreign-owned companies — control or attempt to control part of the region’s water supply, candidates’ stances on water may influence voting this November.

Average inches of rainfall per year in the lower Rio Grande, compared to the 50 inches of water, at least, sugarcane fields need to grow, the Guardian reports. As a result of this discrepancy, made worse by a megadrought in the south Texas borderlands and Mexico, the state’s final sugar mill has closed. Even with irrigation, water needs across the 34,000-acre Texan co-op couldn’t be met. Obligated by a 1944 treaty to deliver 1.75 million acre-feet of water to the U.S. in a five-year cycle, Mexico, plagued by drought, couldn’t deliver either. “It’s not that Mexico is holding the water because they are bad neighbors,” Texas A&M agricultural economist Luis Ribera tells the Guardian. “They’re using it.”

On the Radar
The 300-year-old Filipino town of Pantabangan, submerged in the 1970s to construct a reservoir, has re-emerged amid prolonged dry conditions and extremely low water levels, BBC reports. Nearly half of the Philippines is currently experiencing drought, and the town — which draws visitors whenever visible and has come to be a symbol of water scarcity — has never been above water for this long. From a normal level of 221 meters, the water level is sitting at 50 meters, officials say. Temperatures in excess of 113 degrees Fahrenheit in the country and across Myanmar, Thailand, and Bangladesh have so far killed dozens of people this year.
