Wastewater service charges vary considerably across EPA regions and States. That’s one of the key findings from the National Association of Clean Water Agencies’ (NACWA) Cost of Clean Water Index. If you live in Montana, Wyoming or the Dakotas (EPA Region 8), your average service charge of $261 a year is considerably less than the $884 your fellow Americans up in New England (EPA Region 1) are paying. As you can imagine, much of the difference is to do with population size and geography.
Iron, manganese, arsenic and hydrogen sulfide are indigenous to numerous groundwater aquifers. With the exception of arsenic, these constituents are more prevalent in deeper aquifers that are devoid of dissolved oxygen. This report summarizes the results and conclusions of a groundwater treatment pilot test program. This pilot test program was undertaken to determine the removal performance for arsenic, manganese and iron at the City of Merced’s Well 20 site. Chemical treatment processes required were also studied.

There is little doubt about the importance of taking turbidity readings as part of drinking water treatment. However, there are certain misperceptions about the associated requirements and procedures needed to confirm the validity of those readings. The major points of confusion seem to revolve around perception of the terms “approved,” “calibration,” and “validation.” Here is a quick synopsis on what you really need to know about meeting U.S. EPA Method 180.1: Determination of Turbidity by Nephelometry for accurate turbidity readings.
If A Pipe Leaks In A Forest, Does It Make A Sound? (Part I) addressed condition assessment and leak detection from the perspective of surprises that can arise when “hidden” problems are revealed by acoustic technology. This article introduces several more eye-opening experiences with permanent and mobile acoustic leak detection equipment, plus examples of just how expensive undetected leaks can become when they turn into full-blown water main breaks.
Traditionally when it comes to analysis, there have been two ways to measure pH. The first is the inexpensive method of using test strips, which requires little time or training. The second requires the use of a pH electrode or probe and because it requires more training, time, and equipment, is far more expensive. However, a hybrid application is now available that brings together the ease of use of test strips with technology to ensure preciseness.
