EPA Announces Over $3 Million in Funding to Small Businesses to Develop Environmental Technologies
EPA announced on December 14 that 30 American small businesses will receive funding to develop novel technologies to address pressing environmental and public health problems such as domestic greywater, microplastics, and lead service lines.

Nutrient Smart Recognition Program
WEF and EPA launched the NutrientSmart (NSmart) program in December to help reduce nutrient loadings in waterways by encouraging the adoption of enhanced nutrient management practices by water utilities and distributing information on tools and methods for lowering nutrients.

Fifth Unregulated Contaminant Monitoring Rule
EPA published the fifth Unregulated Contaminant Monitoring Rule (UCMR 5) on December 27 to better understand the national occurrences and levels of 29 PFAS found in the nation's drinking water systems.

What's on the Drinking Water Radar for the Year Ahead: 2019

Being a small-town water operator is not easy; it is up to you to ensure the quality of your community's water day-in and day-out, often with very limited resources. Let WaterOperator.org help you meet the challenge head-on with this list of tools and resources to put on your radar for the year ahead:

• Have you gotten in the groove yet with the new RTCR requirements? Here are two new documents from the USEPA designed to help small public water systems: Revised Total Coliform Rule Placards and a Revised Total Coliform Rule Sample Siting Plan with Template Manual. Additional compliance help, including public notification templates, a RTCR rule guide, a corrective actions guidance and more can be found here.
• While we know your hands are full just getting the job done, there are new and emerging issues you may have to deal with in the year ahead. For example, this past year many communities have been dealing with PFAS contamination issues. This ITRC website provides PFAS fact sheets that are regularly being updated on PFAS regulations, guidance, advisories and remediation methods. Especially of interest is this excel file that has begun to list the different state standards and guidance values for PFAS in drinking water as they are developed. Be sure to check back often for updates.
• Your utility may also have to adjust to new compliance rules in the coming year. In Michigan, for example, a new Lead and Copper Rule arising from the water crisis in Flint has gone into effect, making it the strictest in the nation. Other states, such as Ohio, have also adopted tougher standards, or are now requiring schools to test for lead. Oregon has established temporary rules that will require drinking water systems in the state using certain surface water sources to routinely test for cyanotoxins and notify the public about the test results.
• With a warming climate, these incidences of harmful algal blooms in surface water are on the increase, causing all sorts of challenges for water systems that now have to treat this contaminant. This cyanotoxin management template from the EPA can help assist you with a plan specific to your location.
• Worker turnover and retirements will still be an issue in 2019. According to this article, the median age for water workers in general (42.8 years) and water treatment operators specifically (46.4 years) are both above the national average across all occupations (42.2 years). You can keep transitions as smooth as possible by using EPA's Knowledge Retention Tool Spreadsheet and/or this Electronic Preventive Maintenance Log.
• New Tech Solutions: A UMass lab focusing on affordable water treatment technologies for small systems will be rolling out its Mobile Water Innovation Laboratory in 2019 for on-site testing. In addition, the facility is testing approaches to help communities address water-quality issues in affordable ways. "Early next year, in the maiden voyage of the mobile water treatment lab, UMass engineer David Reckhow plans to test ferrate, an ion of iron, as a replacement for several water treatments steps in the small town of Gloucester, MA.

But even without all these challenges and new ideas for the future, simply achieving compliance on a day-to-day basis can be tricky - if this sounds familiar, you may want to check out our recent video on how operators can approach the most common drinking water compliance issues.

Featured Video: Using Powdered Activated Carbon to Remove Cyanotoxins

In May of this year, the city of Salem, Oregon discovered the state's first-ever algae breach in finished drinking water. Since then, there has been quite a bit of soul-searching, as well as a third-party assessment of exactly what happened and the effectiveness of the water utility's response after the event. In the end, the assessment concluded that the city was not prepared to deal with the public relations fallout, or the more practical matter of helping citizens access emergency water supplies. 

In the meantime, the Oregon Health Authority responded by creating almost unprecedented new cyanotoxin monitoring regulations for systems across the state, and the city of Salem was left to figure out how to cope with what may turn out to be a long-standing threat.

As an emergency measure, the utility started using powdered activated carbon (see video below from Statesman Journal reporter Dick Hughes) but it can cause clogging of the filtration plant.  The city is now also looking into ozone filtration, as well as other improvements including hazard response and crisis communication planning in order to be better prepared to handle future events.
