RIO DE JANEIRO -- At these Olympics, its not always the grass thats greener on the other side. Antawn Jamison Jersey .Its the diving pool.Think Rio officials were embarrassed they had to hire helicopters and spotters to try and keep sewage out of sailing waters? Now they cant seem to get the green out of the diving pool water.That led to some unusual television Friday as underwater cameras tried to focus on amoebae-like shapes that seemed more sea creature than human diver. In the stands, fans cheered when their favorite diver would suddenly emerge from what looked like green slop.It looked bad, though Rio officials insisted it was not really all that bad. Neither, they said, was the chlorine used in the adjacent water polo pool to make it a lighter shade of green for Fridays play.Still, this isnt exactly what they had in mind when promising the Olympics would go green.It doesnt take a genius to know what they did to the pool, U.S. water polo captain Tony Azevedo said. But it doesnt matter. Play in green water, play in chlorinated water, I mean Im an American. All our water is over-chlorinated, so it doesnt really matter.Friday marked three days since the once blue water began turning green, and two days since Olympic officials insisted it was getting better. So much better that the pool was closed for practice Friday as they frantically tried to clean things up before the womens 3-meter springboard preliminary.It didnt work, although the pool did smell somewhat better than it did in the morning when two German divers posted a picture on Facebook showing themselves covering their noses after practice was cancelled.Olympic officials werent exactly forthcoming on what made the water turn green, though those who clean swimming pools quickly identified it as algae. The officials also werent terribly clear on how algae was somehow allowed to grow in a pool being used for the biggest sporting event in the world.We first learned that chemistry is not an exact science, said Rio 2016 spokesman Mario Andrada.That might come as somewhat of a surprise to actual scientists, who say keeping a swimming pool clean and blue isnt that difficult if certain procedures are followed.To them, its easy not being green.There is some imprecision in maintaining chemistry in a large body of water, said Tom Lachocki, executive director of the National Swimming Pool Foundation in Colorado Springs, Colo. However, maintaining disinfectant in water has been the largest public health advance in the last century. The basic principles of maintaining disinfectant, proper pH, and circulation and filtration are scientifically sound and well established.Lachocki, a chemist himself, said making the pool blue again involves a combination of algaecide, chlorine and the proper pH levels.You get algaecide and proper chlorine and youll see that pool clearing up overnight, he said. Within 12-14 hours youll get cleaner water.Rio organizers can only hope that is true. Theyve battled water issues since being awarded the Olympics seven years ago with the promise they would clean up Guanabara Bay, the sailing venue that remains the collection area for much of the citys untreated waste.Theyve already had to deal with a Belgian woman who won a 2012 bronze medal falling ill after sailing the polluted waters of Guanabara Bay. The last thing they need is for pictures of divers doing flips and twists into green water to be iconic images of these games.We certainly could have done better in the beginning to prevent the water from turning green, Andrada admitted. Once it turned green, we again made another bit of a mistake.Its a mistake that made more than a few divers wary, including Britains Tom Daley, who tweeted after finding the pool closed for practice Friday that Hopefully that means we havent been diving in anything too bad the last couple of days!Hopefully not, because the worst case scenario is always that the water is as nasty as it looks.And no one wants to see divers turn green with anything other than envy.----Tim Dahlberg is a national sports columnist for The Associated Press.

The mixed zone is not a place to make friends. BRISTOL, Tenn. -- Kevin Harvick wasnt worried about his poor qualifying at Bristol Motor Speedway. In fact, starting 24th gave Harvick exactly what he wanted to win at Bristol Motor Speedway.It kind of motivates me, Harvick said Sunday. I think its exciting. I like to pass cars.Harvick made the biggest pass with 70 laps to go, sweeping by Denny Hamlin and holding on to take the rain-delayed race at the half-mile concrete track.The victory was Harvicks second of the season and second at Bristol -- his first in 11 years. It also moved him atop the points standings and gave his program a jolt with only three races left until NASCARs Chase starts.Harvick had 13 top-10 finishes in the 18 races since winning at Phoenix in March.Its been one of those deals where things have just not gone exactly right, said Harvick, who led 128 laps. But to have the win now and just try to get that momentum before we get into the Chase and get things rolling is really what we needed.Fittingly for a race halted because of Saturday night storms, Harvick had to sit out one last rain delay before easily pulling away on the restart and cruising to victory.Thank you, thank you, thank you, Harvick said over the radio as he crossed the line.Harvick enticed his car owner -- and retiring driver -- Tony Stewart to do burnouts with him to celebrate the three-time champions last race at Bristol. He wanted Stewart to share the victory lap, but Tony and I arent very good at sign language from one seat to another, he said.Ricky Stenhouse Jr. was second, followed by Hamlin, Austin Dillon and Chris Buescher.Kyle Busch, who led 256 laps, clearly had the strongest car, leading a race-high 256 laps. But he spun on Lap 358 when a part broke and Justin Allgaier, driving in relief of Michael Arnett, hit the No. 18 car flush to end the defending series champs race.Busch was angered by his equipment failure and said the race shop was going to hear about it Tuesday. He also blasted Allgaier and his spotter, saying they shouldve seen Buschs spin and moved clear instead of hitting him. I dont know. Frustrating day. Lets go home, Busch said.Allgaier apologized to Busch. That is the worrst possibly scenario when the leader spins out and you hit them, Allgaier said. Stitched Warriors Jerseys. That was the sentiment of many at Bristol. The end was a welcome relief for race teams, track officials and those who came back out after last nights soaking rains.It was the second time in three races -- Poconos Sunday race ended on a Monday three weeks ago -- that rain impacted a Sprint Cup race and only a fraction of the 160,000 in the stands Saturday night returned for the conclusion.The finish also meant Bristol could begin the massive conversion of its race track to a football field for No. 9 Tennessee vs. Virginia Tech, an event that track GM Jerry Caldwell expects will draw in excess of 155,000 fans.WHOS HOT: Austin Dillon, the surprise winner of the Xfinity race here Friday night, found himself competing for the victory on the final restart with 51 laps to go. He got as high as second before finishing fourth. The result was a boost to Dillons Chase chances, too, who came in as one of the drivers qualifying on points and left with that intact.WHOS NOT: Tony Stewart was hoping to lock up his Chase spot -- hes got a win but stands 27th in points -- with a strong Bristol finish. Instead, he went behind the wall with a vibration just past the halfway point. Stewart finished 30th.THEY SAID IT: The person thats really the biggest moron out there is the spotter of the 46 and driver of the 46 (Justin Allgaier). Ive been wrecking half a lap and they just come up and clean us out. Thats stupid, said Kyle Busch, who wrecked on lap 373 after leading 258 laps.THE BIG ONE: It came on lap 373 on a restart after Kyle Busch was knocked out by an accident. Kurt Busch slid up and was hit by Brad Keselowski, touching off a 10-car wreck that caught up contenders Kyle Larson, Blaney, Chase Elliott and Matt Kenseth. Keselowski said Kurt Busch got loose and by the time I saw it, I was already making contact. It was one of those Bristol things.UP NEXT: Michigan International Speedway, Aug. 28. Matt Kenseth is the defending champion. ' ' '
