Promoting better quality of life for people by improving water systems. Doing it through data, code, utility management, and public policy.

About 80-90% of #PFAS exposure is from sources other than water - consumer goods, household products, food, etc.

Why isn't there an aggressive effort to address those sources?

Is the burden disproportionately being placed on #water utilities?

Women, Wages, and Bottled Water

Despite its high price, bottled water consumption is greatest among the poor & working class. Turns out that the relationship between income & bottled water is distinctly gendered.

"65% of voters support extending SNAP benefits to cover water bills. This includes 83% of Democrats, 61% of Independents, and 50% of Republicans. Voters who live in a SNAP household are especially supportive of this proposal."

Stopping children from dying: one of humanity's greatest achievements.

Dramatic progress has been made across the world.

One example:
In 1970, 1-in-3 newborns in Malawi died before the age of five.

In 1990, this was 1-in-4.

Today it's 1-in-24.

In our @awwa paper, we discuss the drawbacks of regulating HAAs as a group. MCLs related to a group of DBPs weights each one by its conc. But often DBPs with the lowest conc have the highest toxicity.

What's the best path forward?

Today @Interior and @usbr announced the launch of a new large-scale water recycling program and made $180 million from @POTUS' Bipartisan Infrastructure Law available to create new water supplies that are less vulnerable to drought and climate change.

“In the past, society has benefited from making unnecessary exposure to lead and other contaminants unacceptable, but at some level, harms arising from a nocebo effect for trace contaminant exposures may also be considered unacceptable.”

Considering some negative implications of reducing the @CDC blood lead threshold indefinitely and using "no safe level" messaging indiscriminately wrt environmental contaminants. 130+ years of combined clinical/research experience behind this ES&T article: https://t.co/bttASdHdaW

Meet an especially graceful satellite mission: GRACE! 🛰️

GRACE is a pair of satellites that follow each other. They use Earth’s gravity to measure changes in things like ice sheets, glaciers, and even groundwater. The bigger the object, the more it tugs on the satellites.

[California Water Boards @CaWaterBoards]

To address an anticipated 10% reduction in water supply by 2040 due to hotter & drier conditions, the State Water Board has developed a draft report on expediting permitting for seawater desalination plants. Public can comment on report thru noon.

Interesting development we heard today regarding the Grand Ethiopian Renaissance Dam (#GERD) planned activity through a joint press release by #Ethiopia and #Egypt. I got few questions to explain this.
