South Adams County Water and Sanitation District Takes Proactive Step to Treat PFAS, Safeguard Water Supplies
November 28, 2022 —
Cameron McWilliam – Brown and CaldwellDENVER, Colo., Nov. 15, 2022 — The South Adams Country Water and Sanitation District (District) is enhancing its water treatment process to meet EPA Health Advisory Levels (HALs) for per- and polyfluoroalkyl substances (PFAS) in drinking water supplies.
Deemed “forever chemicals,” PFAS is a group of human-made chemicals used in many applications, including stain- and water-resistant fabrics and carpeting, cleaning products, paints, and firefighting foams. PFAS are resistant to grease, oil, water, and heat and may enter water supplies from landfills, the use of firefighting foam (e.g., at airports, fire training facilities, petroleum fires, etc.), industrial sites, and wastewater treatment plant discharge.
The District’s water supply, serving over 67,000 residents in Commerce City and parts of unincorporated Adams County, comes primarily from 13 groundwater supply wells. As it continues to meet all federal and state drinking water requirements, the District has been proactively pursuing PFAS reduction strategies since it first discovered a low-level presence in its water supply through voluntary testing in 2018. Upon discovery, the District stopped drawing from its most impacted wells and has been purchasing additional treated water to blend into its supply to reduce PFAS levels along with optimizing use of their existing granular activated carbon treatment system.
“Ever since the District first began voluntarily testing for PFAS, we have been monitoring for these compounds and working to reduce their impact on our customers,” said District Manager Abel Moreno. “The EPA has moved the goalposts, and we are taking steps to reduce the presence of PFAS even further. We are committed to finding long-term, sustainable solutions to offer our community high-quality drinking water.”
To tackle the challenge, the District has hired leading environmental and construction services firm Brown and Caldwell to design a new 18 million gallons per day (MGD) ion exchange (IX) process at its Klein Water Treatment Facility. IX treatment is currently the most effective technology in removing PFAS/PFOA, consisting of a highly porous resin that acts as a powerful magnet to adsorb and hold onto the substances. The new system at the Klein facility will consist of seven IX treatment trains, a 375,000-gallon equalization tank, and six vertical turbine pumps to feed the IX trains from the District’s 13 groundwater supply wells.
Furthermore, nine 5-micron cartridge filters will be installed to remove particulate matter in the water before reaching the IX trains, thus increasing the efficacy of the treatment process.
Scheduled for completion by the end of 2026, the new IX treatment facility will provide a peak combined capacity of 26 MGD.

July 31, 2013 —
Tred Eyerly, Insurance Law HawaiiThe Federal District Court in Virginia found that allegations of faulty workmanship could arise from an occurrence. Nautilus Ins. Co. v. Strongwell Corp., 2013 U.S. Dist. LEXIS 79163 (W. D. Va. June 4, 2013).
Strongwell supplied certain fiberglass reinforced plastic materials to a subcontractor of Black & Veatch for a construction project at power plant. Black & Veatch subsequently sued Strongwell, claiming that numerous defects in Strongwell's materials and work were discovered after the project was completed. The complaint further alleged that as a result of the defects, there was widespread property damage to portions of the power plant.
Nautilus defended under a reservation of rights. Nautilus also filed suit for a declaratory judgment that to establish it had no duty to defend or indemnify Strongwell. Strongwell moved to dismiss the complaint insofar as it requested a declaration that there was no duty to defend. Strongwell also filed a motion to stay the coverage action until the underlying case was completed.

Five Reasons to Hire Older Workers—and How to Keep Them
July 06, 2020 —
Charlie Kimmel - Construction ExecutiveThe economic downturn in 2008 created a black hole of talent in the construction industry. As a result, finding project managers between the ages of 28 and 33 and superintendents between the ages of 23 and 30 in today’s market can be difficult, if not impossible in some cases. To make up for this gap in available talent, construction executives are going to have to look to project managers and superintendents in the 58-to-64 age range. Fortunately, there are numerous benefits to hiring older workers.
1. OLDER WORKERS WANT TO MENTOR THE NEXT GENERATION.
This is their most significant benefit: the older generation truly enjoys teaching younger construction workers and passing on skills and knowledge, while also getting to do a job they’re good at. This means investing in one experienced worker today can pay dividends for the quality of a company’s workforce for decades to come, as mentorship programs have proven to increase the skills and loyalty of younger workers. If a company wants someone with deep knowledge and broad experience to help mold the next generation of construction workers, they should hire an older employee.

Scary Movie: Theatre Developer Axed By Court of Appeal In Prevailing Wage Determination Challenge
July 19, 2017 —
Steven M. Cvitanovic & Omar Parra - Haight Brown & Bonesteel LLPThe First Appellate District of the California Court of Appeal recently held that the construction of a movie theater, which was performed in furtherance of a city’s redevelopment agenda, constitutes a “public work” within the meaning of California’s prevailing wage law. Cinema West, LLC v. Christine Baker, No. A144265, (Cal. Ct. App. June 30, 2017).
Like many California cities, the City of Hesperia (the “City”) endeavored to revitalize its downtown. In furtherance of this goal, the City acquired vacant property in its downtown with the hope of turning it into a new city hall, a public library, and “complimentary retail, restaurant, and entertainment establishments.” After completing construction of the civic buildings, the City entered into discussions with Cinema West, LLC (“Cinema West”) for the construction of a “state-of-the-art cinema experience.”
Under the agreement with the City, Cinema West agreed to purchase the property from the City at fair market value, obtain financing for the construction costs, and build and maintain the movie theater. The City, on the other hand, agreed to provide Cinema West with an interest-bearing loan forgivable over ten years, and to construct an adjacent parking lot “for use by Cinema West... as a parking lot for the movie theater.” The City, moreover, agreed to issue Cinema West a one-time payment as consideration for the operating covenant.

What Lies Beneath
April 10, 2023 —
Grace Austin - Construction ExecutiveIndustry experts call it the “Wild Wild West,” and it certainly could be considered a new frontier: private utility locating. While public utility locating is familiar territory, private utility locating is decidedly newer—and already changing rapidly. Public or private, utility location is imperative to safe and cost-effective construction. Hidden utilities can lead to damage, driving up costs and causing unexpected project delays. They can also be dangerous to both workers and the public, causing injuries and even deaths.
The Common Ground Alliance’s 2021 DIRT Report—which compiles information from CGA’s Damage Information Reporting Tool program—found that natural gas and telecommunications were the leading utilities damaged. DIRT received more than 230,000 reports on damages and near-misses in 2021. Clearly, the industry can do better.
CALL BEFORE YOU DIG
Utility location mapping in the United States began in earnest in the mid-20th century, according to GPRS, a private utility-mapping company that was founded in 2001. As postwar development shifted into high gear, the utility industries realized that power, water, gas, phone and other utilities were now being installed in the ground—and there needed to be a better system to prevent service disruptions and accidents.

Homebuilder Confidence Takes a Beating
October 21, 2013 —
CDJ STAFFHomebuilder confidence dropped to fifty-five percent in October, the lowest percentage seen in the last four months. The score had been rising on the strength of renewed home sales. The current slump is attributed to increases in interest rates, which have made home purchases more expensive for prospective buyers, and the uncertainty of the budget struggle in Washington.
John Stumpf, the chairman and CEO of Wells Fargo said that “home price appreciation remains strong and affordability remains excellent.” Mr. Strum has “guarded optimism” over the effects of the budget struggle.
