The 3M Co. and other major manufacturers of firefighting foams that have contaminated drinking water near military bases should have known they were making and selling products that presented a health risk, according to a suit filed Friday in U.S. District Court in Philadelphia against six foam makers. The foam - known as Aqueous Film Forming Foam or AFFF - was sold to the military and used at two naval air bases in Warminster and Horsham Townships, among hundreds of sites nationwide.

The Air Force said last week that it would stop using the potentially dangerous firefighting foam that over years contaminated some local water supplies, but no other military branch has a public plan to ban the foam at its bases. Since 2014, 16 wells have been closed in Bucks and Montgomery Counties after they were found to be tainted with PFOA and PFOS, chemicals linked to cancer that leached into local water supplies from firefighting foam used at two now-closed naval air bases.

You couldn't pay Chris Salazar to go out on a North Philadelphia roof Monday in the 90-degree heat. But he would do it free. Salazar, an executive for a New Jersey roof-coating manufacturer, and about two dozen other volunteers scaled 32-foot ladders Monday to apply reflective layers of acrylic to the roofs of 20 rowhouses, capping a major energy retrofit on the 1200 block of West Seltzer Street. Most of the volunteers were attending the four-day International Roof Coatings Conference, which opened Monday at the Sonesta Hotel Philadelphia.

The long : Last week, the Please Touch Museum blocked out 1,100 square feet between River Adventures and the carousel by filling three soft, holey foam walls with hundreds of oversize blue foam bricks and noodles and plastic balls. The short : Get it? Blocked out? The demo : Three and up. (No fun for crawlers or new walkers.) The philosophy : "Unstructured play" continues to trend. The idea, says a museum rep: "Allow [children] to use their imaginations and creativity and to also develop fine and gross motor skills.

Question: I had our attic spray-foamed in 2010. Our HVAC contractor recently did a semiannual service. The technician came down from the attic, where he was checking the air handler, and he was wringing wet with sweat. Another technician said we needed an energy consultant to check the spray-foam job since leaks in the foam were likely allowing hot, humid air into the attic. The consultant suggested removing all the batt insulation in the ceiling and redoing the spray foam to totally encapsulate the attic.

Two Cape May Point homeowners are exploring the economics of building at the Shore using energy-efficient design. But they also have geared the house for graceful aging when they retire. The first thing Ed Barnhart and fiancee Anne Downey, both 55, did was plan for a first-floor bedroom and bathroom with wider doors and no thresholds. Situated near the southernmost tip of New Jersey, the house totals 2,132 square feet and was completed in May 2012 at a cost of $566,000. With it, Barnhart, an architect by training, faced a challenge: He wanted to create something state-of-the-art that would stand the test of time and that also availed itself of Energy Star technology and a modern construction and design interpretation.

Coroner: Teen in Asiana crash killed by vehicle SAN MATEO, Calif. - As the wreckage of Asiana Flight 214 burned, Ye Meng Yuan was lying on the ground just 30 feet away, buried by the firefighting foam rescue workers were spraying to douse the flames. No one knows exactly how the 16-year-old Chinese student got to that spot, but officials say one thing is clear now: She somehow survived the crash. And in the chaotic moments that followed - flames devouring the fuselage, those aboard escaping by emergency slides, flight attendants frantically cutting away seat belts to free passengers - a fire truck ran over Yuan, killing her. The new details - released yesterday by the coroner's office - compounded the tragedy for her family and confirmed the growing suspicions that emergency workers have had since soon after the July 6 crash: One of the three who died did so by rescuers' actions.

W E DON'T pay much attention to bubbles in our beer, unless they're foaming over the coffee table. When it comes to beer pleasure, though, bubbles are right up there with color, aroma, flavor, body and buzz. So, with the help of West Chester University chemistry professor Roger Barth, Ph.D., author of The Chemistry of Beer (Owl's Nest Publishing); Marty Nachel, whose second edition of Beer for Dummies (Wiley) was just released; and the draft beer gurus at Anheuser-Busch, here are 16 things to know about foam.

Question: What causes my urine to have a lot of foam? Is it serious? Answer: Have you ever had lemon meringue pie? Those tall peaks of frothy white that make up meringue are made from two simple ingredients: sugar and egg whites. When whipped, egg whites will at first foam, and then stiffen into white peaks with continued beating. That's a result of the unique properties of the albumin protein of egg whites. It's normal to have a trace of protein in standing urine, which foams like meringue as the urine mixes with the water in the toilet.
