Groups across Mississippi rallied Wednesday to support Jackson in beating the sweltering August heat amid the city’s ongoing water crisis, and the federal government is also lending a hand.

Mayor Chokwe Antar Lumumba said at an afternoon news briefing that he had received a pledge of support from President Joe Biden, who the previous night approved Mississippi’s emergency declaration, freeing up federal resources to bolster the state’s response.

Lumumba said both Biden and Vice President Kamala Harris “assured me that the eyes of Washington are watching the city of Jackson,” and that their commitment to solve the water crisis extends beyond the immediate needs and toward finding a long-range solution.

White House Press Secretary Karine Jean-Pierre said the Environmental Protection Agency would send an expert to Jackson to assess its water treatment plants and expedite repairs.

As the Mississippi Emergency Management Agency and National Guard worked to get drinkable and non-drinking water to more than 150,000 Jackson residents throughout the week, other local organizations stepped in to help.

On an “uncomfortably humid” day when temperatures were expected to reach 92 degrees, according to AccuWeather, YMCAs across the city offered free showers to local college students, WAPT-TV reported.

Excessive rainfall had doused Jackson and central Mississippi throughout August, and recent flooding on the Pearl River caused pumps to fail at a Jackson water treatment plant, officials said.

Here’s what to know about the response to Jackson’s water shortage and who’s impacted:

Water from the faucets still not drinkable

Lumumba said residents of the capital city still need to boil water for drinking, washing dishes and other activities, like brushing their teeth.

An emergency pump was installed Wednesday at the O.B. Curtis Water Treatment Plant to restore water pressure, and Lumumba said city dwellers should notice improvement in that regard by Wednesday evening. But tests Tuesday night showed issues with the water chemistry, leading to a drop in output and water pressure, and a requirement to boil water for certain uses remained in effect.
