Together, we can create a safer, cleaner environment for your community and future generations. ## What are PFAS, and why do people call them forever chemicals? PFAS are man-made chemicals used for decades because they resist heat, oil and water. They break down very slowly, so they stay in soil, groundwater and people. That is why they are called [forever chemicals](https://aes.multisites.ai/glossary/forever-chemicals). Our page on [what PFAS are](https://aes.multisites.ai/what-are-pfas) gives the background, and the glossary has an entry for [PFAS](https://aes.multisites.ai/glossary/pfas). Two compounds drive most rules and lab reports: [PFOA](https://aes.multisites.ai/glossary/pfoa) and [PFOS](https://aes.multisites.ai/glossary/pfos). Lab results come in [parts per trillion](https://aes.multisites.ai/glossary/parts-per-trillion-ppt). The numbers are tiny, so sampling and lab method both matter. ## Where do PFAS contamination sources show up? PFAS show up near places that made, used or burned PFAS products. AES lists industrial discharge, landfill leachate and firefighting foam as the main ways PFAS reach the environment. Once released, they move easily through soil and groundwater and can reach drinking water sources and farmland.

Our page on [PFAS contamination](https://aes.multisites.ai/pfas-contamination) explains how PFAS spread, and [PFAS drinking water](https://aes.multisites.ai/pfas-drinking-water) covers how they reach taps. ## What does the EPA drinking water rule require now? As of October 30, 2026, EPA’s drinking water page lists a limit of 4.0 parts per trillion for PFOA and PFOS, plus limits for PFHxS, PFNA and GenX. EPA also announced two proposals on May 18, 2026. One gives water systems a chance to request more time. The other would remove limits for three PFAS and the mixture rule. We read this from the EPA page itself, last updated May 18, 2026. Rules in this area change often, so always check the [EPA PFAS drinking water page](https://www.epa.gov/sdwa/and-polyfluoroalkyl-substances-pfas) before you rely on a date or a number. Item What EPA’s page says (as of October 30, 2026) PFOA limit Maximum Contaminant Level of 4.0 ppt PFOS limit Maximum Contaminant Level of 4.0 ppt PFHxS, PFNA, HFPO-DA (GenX) 10 ppt each, listed in the final rule table Mixtures of two or more of PFHxS, PFNA, HFPO-DA and PFBS Hazard Index of 1 Initial monitoring Three years, by 2027 Reduce levels if over the limit Five years, by 2029 Proposal 1 (May 18, 2026) Keep PFOA and PFOS limits, with an option to request two more years, to 2031 Proposal 2 (May 18, 2026) Rescind rules for PFHxS, PFNA, HFPO-DA and the Hazard Index Both proposals were open for public comment when EPA published them. A proposal is not a final rule. Until EPA acts, the page’s description of the final rule is what it lists. Read the [MCL](https://aes.multisites.ai/glossary/mcl-maximum-contaminant-level) entry in the glossary for what these limits mean. Our own explainers go deeper: the guide on the [PFAS drinking water rule explained](https://aes.multisites.ai/guides/pfas-drinking-water-rule-explained) and the post on the [2031 proposal](https://aes.multisites.ai/blog/epa-pfas-drinking-water-rule-2031-proposal). Our [PFAS regulations](https://aes.multisites.ai/pfas-regulations) page tracks the wider picture. The drinking water rule binds public water systems. Other rules may apply to your well, your plant or your soil. Ask your regulator which ones. ## How is PFAS tested and sampled? AES says the only reliable way to detect PFAS is professional environmental testing. Crews collect samples of soil, groundwater and drinking water and send them to a laboratory for analysis. At parts-per-trillion levels, how you collect the sample matters as much as the lab method. A typical testing path: 1. **Site assessment.** Review the history of the site and where PFAS may have been used. See [PFAS assessment](https://aes.multisites.ai/pfas-assessment). 2. **Sampling plan.** Choose points, depths and sample types. See [PFAS sampling](https://aes.multisites.ai/pfas-sampling). 3. **Collection.** Trained staff collect samples with a chain of custody record. 4. **Lab analysis.** The lab reports results by compound. 5. **Report.** The report compares results to the limits that apply and recommends next steps. AES says it follows EPA and state-approved testing protocols. Our [PFAS testing](https://aes.multisites.ai/pfas-testing) page has more. Public utilities test too. The City of St. Louis Water Division says it has performed periodic voluntary PFAS sampling since 2020 and takes part in EPA’s fifth Unregulated Contaminant Monitoring Rule, which tests for 29 PFAS. It reports that June 2024 samples at both treatment plants showed all PFAS levels below detection limits. That is one system. Your own well, plant or soil needs its own results. If you hold a lab report and want to read it, the post on [how to read a PFAS lab report](https://aes.multisites.ai/blog/how-to-read-a-pfas-lab-report) explains the columns, and the guide on [PFAS testing for property owners](https://aes.multisites.ai/guides/pfas-testing-for-property-owners) explains what to sample first. ## What treatment technologies remove PFAS from water and soil? AES lists granular activated carbon, ion exchange, reverse osmosis and thermal destruction. Carbon and ion exchange pull PFAS out of water, reverse osmosis separates them physically, and thermal destruction handles concentrated waste. Soil may be excavated or treated in place. No single method fits every site. Method How it works Where AES says it fits [Granular activated carbon (GAC)](https://aes.multisites.ai/glossary/granular-activated-carbon-gac) Water passes through carbon that holds PFAS Removes long-chain PFAS [Ion exchange](https://aes.multisites.ai/glossary/ion-exchange) Resin captures PFAS from water Captures long and short chain PFAS Reverse osmosis A membrane separates PFAS from water Physically separates PFAS from water Thermal destruction High heat breaks down concentrated waste Destroys concentrated PFAS waste Excavation or in-situ treatment Remove soil, or treat it where it sits Soil, per AES’s pages on [PFAS soil treatment](https://aes.multisites.ai/pfas-soil-treatment) Choose a method after the assessment, not before. The PFAS present, the flow of water, the budget and the discharge rules all change the answer. Our page on [PFAS treatment technologies](https://aes.multisites.ai/pfas-treatment-technologies) compares them, [PFAS water treatment](https://aes.multisites.ai/pfas-water-treatment) covers water systems, and [contaminated groundwater treatment](https://aes.multisites.ai/contaminated-groundwater-treatment) covers groundwater. For the soil side, the glossary entry on [soil remediation](https://aes.multisites.ai/glossary/soil-remediation) gives the basics. ## How is PFAS waste handled and disposed of? Treatment creates waste: spent carbon, used resin, concentrated liquids and contaminated soil. These need safe handling and a lawful disposal route. AES says it manages PFAS waste removal and off-site disposal in line with the latest environmental safety requirements, plus long-term monitoring to check that systems keep working. What to settle before a cleanup starts: - Where the spent media will go after it leaves your site - Who signs the paperwork and holds the records - How long monitoring will run after treatment - Whether the waste counts as [hazardous waste](https://aes.multisites.ai/glossary/hazardous-waste) under the rules that apply to you Treatment without a disposal plan only moves the problem. Read more on [PFAS waste disposal](https://aes.multisites.ai/pfas-waste-disposal) and on [hazardous waste disposal](https://aes.multisites.ai/hazardous-waste-disposal). ## Which clients and sites does AES serve? AES says it serves municipalities, industrial facilities and property owners with PFAS testing, removal and remediation. Each audience has its own page: municipal water, industrial and manufacturing sites, airports, landfills, schools, farms and military bases. AES says its work covers Missouri and the Midwest. Different sites need different proof. A water utility needs compliance data. A factory may need a source investigation. A school needs results it can explain to families. A farm needs soil and irrigation water results. Start from the page that matches your site in the table above, then talk to AES about the scope. For general questions, the [PFAS FAQs](https://aes.multisites.ai/pfas-faqs) page answers the common ones, and [health effects of PFAS](https://aes.multisites.ai/health-effects-of-pfas) covers what the studies say. ## What happens in an emergency PFAS spill? Call right away. AES says its team is available 24/7 for urgent cleanup needs and can typically be on-site within hours of receiving a call, depending on location. The first goal is to contain the release before it reaches soil, storm drains or groundwater. If you are the person on scene: 1. Keep people away from the spill. 2. Stop the source if you can do so safely. 3. Block storm drains and ditches in the path. 4. Note what was released, how much, and where it went. 5. Call your regulator when the rules require it, and call AES at (314) 865-2662. Details are on the [emergency PFAS cleanup](https://aes.multisites.ai/emergency-pfas-cleanup) page. ## How do I choose a PFAS remediation company? Choose a company that tests, treats and handles waste, and that explains each step in plain terms. AES says a qualified contractor should offer testing, treatment, reporting and compliance support. Ask for sample reports and a clear scope. Avoid anyone who names a treatment method before they see data. Our pages on [PFAS remediation](https://aes.multisites.ai/pfas-remediation), [PFAS removal](https://aes.multisites.ai/pfas-removal), [PFAS remediation services](https://aes.multisites.ai/pfas-remediation-services) and [how to choose a PFAS remediation company](https://aes.multisites.ai/pfas-remediation-company) go through the questions to ask. ## Next step Start with a site assessment so the plan rests on data. Call (314) 865-2662 or use the form at [/contact](https://aes.multisites.ai/contact), and see [PFAS testing](https://aes.multisites.ai/pfas-testing) for what the first visit covers. ## Frequently asked questions ### What is the EPA limit for PFOA and PFOS in drinking water? EPA's drinking water page lists a Maximum Contaminant Level of 4.0 parts per trillion for each of PFOA and PFOS. As of October 30, 2026, EPA has also proposed a compliance extension option to 2031. Check the EPA page for updates, since the rule is in flux. ### Is the PFAS drinking water rule still in effect? EPA's page, last updated May 18, 2026, still lists the limits and describes two proposals that would change parts of the rule. One keeps the PFOA and PFOS limits with an option for more time. The other would rescind limits for PFHxS, PFNA, GenX and the Hazard Index. Proposals are not final rules. ### Can I test my own water for PFAS? The risk is getting a wrong answer. AES says the only reliable way to detect PFAS is professional environmental testing. Trace amounts matter at parts per trillion, and sample bottles, handling and lab method all affect the result. Use a lab and a sampler who follow a recognized method. ### How do you remove PFAS from water? AES lists granular activated carbon, ion exchange, reverse osmosis and thermal destruction for concentrated waste. Carbon removes long-chain PFAS, ion exchange captures long and short chains, and reverse osmosis physically separates PFAS from water. The right mix depends on the site and the PFAS present. ### What do you do with PFAS-contaminated soil? AES says soil options include excavation and in-situ treatment, along with off-site disposal of contaminated material. The choice depends on how deep the PFAS go, how much soil is affected, and what regulators require. A site assessment comes first. ### Do you respond to emergency PFAS spills? AES says its team is available 24/7 for urgent cleanup needs, and that it can typically be on-site within hours of receiving a call, depending on location. For a spill, call (314) 865-2662 and describe what was released and where. ### What is a Hazard Index in PFAS rules? It is a way to add up the combined risk of several PFAS found together. EPA's page says it applies to mixtures containing two or more of PFHxS, PFNA, HFPO-DA (GenX) and PFBS, with a limit of 1 (unitless). EPA has proposed to rescind it. ## Terms on this page - [Granular activated carbon (GAC)](https://aes.multisites.ai/glossary/granular-activated-carbon-gac) - [MCL (maximum contaminant level)](https://aes.multisites.ai/glossary/mcl-maximum-contaminant-level) - [Parts per trillion (ppt)](https://aes.multisites.ai/glossary/parts-per-trillion-ppt) - [Forever chemicals](https://aes.multisites.ai/glossary/forever-chemicals) - [Soil remediation](https://aes.multisites.ai/glossary/soil-remediation) - [Hazardous waste](https://aes.multisites.ai/glossary/hazardous-waste) - [Ion exchange](https://aes.multisites.ai/glossary/ion-exchange) - [PFAS](https://aes.multisites.ai/glossary/pfas) - [PFOA](https://aes.multisites.ai/glossary/pfoa) - [PFOS](https://aes.multisites.ai/glossary/pfos) ## Sources 1.
