ST. LOUIS 鈥 For the first time in roughly 40 years, the Environmental Protection Agency used its emergency authority to halt the sale of a weed-killing pesticide that harms the development of unborn babies.
Officials took the rare step this week because the pesticide DCPA, or Dacthal, could cause irreversible damage to fetuses, including impaired brain development and low birthweight.
The agency struggled to obtain vital health data from the pesticide鈥檚 manufacturer on time and decided it was not safe to allow continued sale, the EPA announced Tuesday.
鈥淚n this case, pregnant women who may never know they were exposed could give birth to babies that experience irreversible lifelong health problems,鈥 said Michal Freedhoff, assistant administrator for EPA鈥檚 Office of Chemical Safety and Pollution Prevention.

DCPA is mostly used on broccoli, cabbage and certain other crops, with about 84,000 pounds used on average in 2018 and 2020, officials said.
In 2023, the EPA assessed the pesticide鈥檚 risks and found it was dangerous even if a worker wore personal protective equipment. The manufacturer instructed people to stay off fields where the pesticide was applied for 12 hours, but agency officials said it could linger at dangerous levels for more than 25 days.
The pesticide is made by AMVAC Chemical Corp. The company did not immediately return a request for comment late Wednesday.
In comments to the EPA earlier this year, the company said new protocols could help keep people safe. It proposed longer waiting periods before workers enter fields where the pesticide was applied and limits on how much of the chemical could be handled.
Federal officials said the company鈥檚 proposed changes weren鈥檛 enough. The emergency order was necessary because the normal review process would take too long and leave people at risk, according to the agency鈥檚 statement.
States That You Should Think Twice About Swimming In
Finding clean lakes and rivers

For many Americans, lakes and rivers provide a much-needed escape鈥攁 place to cool off on a hot day, relax with loved ones, or simply enjoy the beauty of nature. However, water quality remains a major public health concern across large portions of the United States. According to data from the Environmental Protection Agency (EPA), over 70% of freshwater lakes, ponds, reservoirs, and wetlands (by acreage) and over 42% of creeks, rivers, and streams (by mileage) are considered too polluted for primary contact recreation such as swimming.
To help monitor and protect U.S. waterways from harmful contaminants, the Federal Water Pollution Control Act was significantly reorganized and expanded in 1972 to become known as the . These amendments made it unlawful to discharge pollutants into most waters without a permit, empowered the EPA to implement pollution control programs, and funded the construction of sewage treatment plants.
While these actions are tangible progress towards protecting U.S. water quality, several challenges remain. One of the biggest hurdles faced today is nonpoint source pollution鈥攃ontaminants that originate from many diffuse sources and collect in America鈥檚 waters鈥攚hich is difficult to trace and therefore thinly regulated by the CWA. Major obstacles like nonpoint source pollution, particularly , highlight the need for continued efforts to ensure clean water for all.

Top Causes of Recreational Waterborne Disease Outbreak

On average, there are nearly 35,000 waterborne illness cases caused by recreational water use in the U.S. every year. 聽from sewage spills, animal waste, fecal incidents, water runoff after heavy rain, and naturally-occurring organisms can all contribute to water pollution, leading to health risks for swimmers ranging from gastrointestinal discomfort and skin rashes to more emergent health problems like respiratory complications, and even death.
鈥攁 highly-contagious virus that causes vomiting, diarrhea, and stomach pain鈥攊s the most commonly acquired illness from recreational water disease outbreaks in untreated waters. With an average of over 18,000 cases reported annually from 1971 through 2021, it accounts for over 55% of diseases linked to primary contact water recreation鈥攚here the potential for ingestion of water is likely, such as swimming, diving, or surfing. A more dangerous cause of illness is 鈥攁 bacteria sometimes found in contaminated water. While it is responsible for an average of just 232 cases per year from water recreation, if left untreated, a 鈥渟taph鈥 infection can cause sepsis or can even be fatal.
Recreational-Use Water Assessment Progress by State
Only 19 states have assessed a majority of their recreational-use lake and river waters for impairments

Despite being established in 1972, the CWA has fallen short of its goal to make 100% of U.S. waters 鈥渇ishable and swimmable鈥 in large part due to inefficient and insufficient water quality monitoring. Just 19 states have recently assessed a majority of their recreational-use lakes and rivers for impairments, with Rhode Island being the only state to completely assess all of its recreational-use water bodies. Perhaps surprisingly, Wyoming, a state known for its natural beauty and outdoor recreation, has yet to sufficiently assess any of its several lakes and reservoirs designated for primary water contact use, and has evaluated just 5.7% of its creeks, rivers, and streams.
A major roadblock to water quality monitoring is the 聽by the EPA. Instead, the EPA relies heavily on state environmental agencies to regulate themselves, but without proper oversight and inadequate funding, some states are forced to make tough decisions such as only prioritizing perennial waterways or dedicating a disproportionate amount of resources on their most polluted water bodies. Lenient runoff pollution regulations, inefficient government enforcement of permit requirements, and weak management of interstate water pollution also contribute in creating a significant blind spot in water quality monitoring.
Methodology

The data used in this analysis is from the U.S. Environmental Protection Agency鈥檚 (EPA) 聽data. In order to determine the states with the worst water quality for swimming, researchers calculated the percentage of total acreage or mileage of assessed, untreated waters that were impaired for primary water contact. Impaired waters are bodies of water polluted by various sources such as industrial waste, sewage, or agricultural runoff, which makes them unsuitable for their designated uses. Under the mandate of the Clean Water Act, states are required to identify these polluted waters every two years and to take actions towards reducing this pollution. In some cases, broader recreational-use categories were used in states where primary water contact is not distinguished, and only waters designated with sufficient information were considered assessed. Untreated recreational-use waters, unlike chlorinated swimming pools, contain water that has not undergone a disinfection or treatment process to maintain good microbiological quality for recreation.
For clarity, acreage-based water bodies were grouped together, including: lakes, ponds, reservoirs, and wetlands, while mileage-based water bodies such as creeks, rivers, and streams were analyzed collectively. Further, the latest organizational submission data for each state was used, and other water bodies鈥攕uch as oceans, Great Lakes, beaches, and bays鈥攚ere excluded due to state-to-state data inconsistencies in categorization and reporting. For additional context, the percentage of primary-contact-use waters assessed, total assessed primary-contact-use waters impaired, total primary-contact-use waters assessed, and total primary-contact-use waters not assessed were calculated for both acreage- and mileage-based water bodies.
