Question: There is a city that a prominent adult contemporary band from this period, along with the Eagles and the person who said the results were racist, was named after. How close is Wrigley Field to the source of drinking water for this city?

historically, philadelphia sourced its water by the fairmount water works, the nation's first major urban water supply system. in 1909, water works was decommissioned as the city transitioned to modern sand filtration methods. today, the philadelphia water department (pwd) provides drinking water, wastewater collection, and stormwater services for philadelphia, as well as surrounding counties. pwd draws about 57 percent of its drinking water from the delaware river and the balance from the schuylkill river. the public wastewater system consists of three water pollution control plants, 21 pumping stations, and about 3,657 miles of sewers. a 2007 investigation by the environmental protection agency found elevated levels of iodine-131 in the city's potable water. [citation needed] in 2012, the epa's readings discovered that the city had the highest readings of i-131 in the nation. the city campaigned against an associated press report that the high levels of i-131 were the results of local gas drilling in the upper delaware river. [citation needed] <SEP> The Hot 100 and Easy Listening charts became more similar again toward the end of the 1960s and into the early and mid-1970s, when the texture of much of the music played on Top 40 radio once more began to soften. The adult contemporary format began evolving into the sound that later defined it, with rock-oriented acts as Chicago, The Eagles, and Elton John becoming associated with the format. <SEP> Much media attention on the season had been focused on the three black singers, Fantasia Barrino, LaToya London, and Jennifer Hudson, dubbed the Three Divas. All three unexpectedly landed on the bottom three on the top seven result show, with Hudson controversially eliminated. The prolonged stays of John Stevens and Jasmine Trias in the finals, despite negative comments from the judges, had aroused resentment, so much so that John Stevens reportedly received a death threat, which he dismissed as a joke 'blown out of proportion'. Elton John, who was one of the mentors that season, called the results of the votes "incredibly racist". <SEP> the curious location on catalina island stemmed from cubs owner william wrigley jr.'s then-majority interest in the island in 1919. wrigley constructed a ballpark on the island to house the cubs in spring training: it was built to the same dimensions as wrigley field. (the ballpark is long gone, but a clubhouse built by wrigley to house the cubs exists as the catalina county club.) however, by 1951 the team chose to leave catalina island and spring training was shifted to mesa, arizona. the cubs' 30-year association with catalina is chronicled in the book, the cubs on catalina, by jim vitti . . . which was named international 'book of the year' by the sporting news. <SEP> Water is collected and transported through tunnels located close to 200 feet beneath the lake, varying in shape from circular to oval, and ranging in diameter from 10 to 20 feet. The tunnels lead from the cribs to one of two water purification plants located onshore, the Jardine Water Purification Plant (the world's largest) and the Eugene Sawyer Water Purification Plant, where the water is then treated before being pumped to all parts of the city as well as 118 suburbs. The water cribs in Chicago are structures built to house and protect offshore water intakes used to supply the City of Chicago with drinking water from Lake Michigan. <SEP> In the summer, however, or on any warm and breezy day, the wind often comes from the south and the southwest, which means the wind is`` blowing out'' and has the potential to turn normally harmless fly balls into home runs. A third variety is the cross-wind, which typically runs from the left field corner to the right field corner and causes all sorts of havoc. In April and May the wind often comes off Lake Michigan (less than a mile to the east), which means a northeast wind ``blowing in ''to knock down potential home runs and turn them into outs. Depending on the direction of the wind, Wrigley can either be one of the friendliest parks in the major leagues for pitchers or among the worst. This makes Wrigley one of the most unpredictable parks in the Major Leagues.
