The U.S. Environmental Protection Agency’s (EPA) is proposing a revised Lead and Copper Rule to be implemented in 2024, or later. Revisions to the rule include modifications in sample collection for those sample sites with Lead Service Lines versus those without Lead Service Lines. A Lead Service Line is a lead pipe that connects tap-water service between a water main and house or building….
Biosolids: The Ultimate Recycling Success Story
In the wastewater treatment world, biosolids are often seen as the ultimate recycling success story. Biosolids are the nutrient-rich organic byproducts resulting from wastewater treatment and over 60% of biosolids produced nationally in the U.S. are land applied. They are used in agriculture, landscaping, forestry, and even by homeowners on lawns and gardens. Although biosolids are under scrutiny once again due to the source of their composition—human and industrial waste—preliminary evidence suggests that the beneficial use of biosolids rests on solid ground.
To learn more about the future of biosolids, new Babcock staff member, Colleen Thompson, interviewed Greg Kester, Director of Renewable Resource Programs at the California Association of Sanitation Agencies (CASA). Greg is the subject matter expert when it comes to emerging issues regarding all renewable energy, recycled water, biosolids, and climate change mitigation. “Biosolids have a plethora of benefits, they assist in creating healthy soils which help crop growth, they are significant mitigators of climate change, reduce irrigation use, offset the use of inorganic fertilizers, and essentially are the best example of recycling,” said Kester. In fact, many agricultural areas depend on biosolids to help…
A Quick Year in Review:2020
To Grab or to Composite...That is the PFAS Question!
The debate regarding the most appropriate method to collect non-potable liquids—specifically POTW influents and effluents—continues. Last month California State Water Quality Control Board (SWQCB) staff appeared to walk back parts of the original Phase III PFAS monitoring orders, directing the responsibility for making decisions regarding sampling techniques back to the agency and their laboratory. October is upon us and water treatment professionals are wondering…

When the Smoke Clears: Aftereffects of Wildfires on Communities’ Water Quality
It is impossible to overstate the tragedy of the Camp and Woolsey fires. The road to recovery will be a long, expensive, and painful one and, unfortunately, rebuilding is only the first of many costs. In addition to the obvious aftermath of a wildfire, there is a subtle yet salient issue these communities will now face: tainted water quality.
