Members of Congress have redirected roughly $2.3 billion in federal water funds toward political pet projects over the past two years, cutting at times into the money that could have been made available for poorer, needier communities. As a result, 38 states and territories have been shortchanged about $660 million in federal water aid, according to data obtained and analyzed by The Washington Post. The problem is expected to worsen in the coming fiscal year, as House Republicans eye a $1.7 billion cut to the overall funding that Washington sends states for their water needs.
