In this research work, three moments are analyzed in the reduction of contamination of the waters of the interior bay of Lake Titicaca, the first is the mechanical harvesting of duckweed, a second aspect is the bottom aeration in two control stations and the third refers to the monitoring of water quality based on the methodology of the National Water Authority. The water quality sampling was carried out in two zones and during the period from 2008 to 2017, being analyzed in the water quality laboratories of the Special Binational Lake Titicaca PELT Project. Physicochemical and microbiological parameters were analyzed using EPA and APHA guidelines, nutrients were determined using spectrophotometry. The main objective is to evaluate the reduction of water pollution, through the process of aeration and mechanical harvesting of lentil in the interior bay of Lake Titicaca in Puno. The aeration system allowed improvements in dissolved oxygen concentration levels, reaching levels up to 8.2 mg / l, which allowed reducing the organic load progressively from 2008 to 2013 (aeration period) and achieving its moderate control at from 2014 to 2017 (period without aeration), the turbidity conditions were controlled by increasing the appearance of the body of water with better visibility, reduction of odors and increased birdlife and the return of aquatic species. The lentil harvest has allowed better surface aeration, reducing production in 2007 was 12,683 m3 / year and in 2011 with 1,352 m3 / year. The water quality monitoring pH during aeration was 9.54 and after 10.25; dissolved oxygen (DO) before aeration was 1 mg / l. during aeration 8.20 mg / l and after aeration 4.94 mg / l; the average nitrate before aeration was 1.13 mg / l and after it was 6.13 mg / l, compared to the maximum standard of 13 mg / l, without exceeding the range; the BOD5 before the project was 27 mg / l, then 11.61 mg / l, all the values exceed the average range; and the thermotolerant coliforms during the process were 1645 NMP / 100 ml and afterwards it was 1716 NMP / 100 ml; the average dissolved oxygen (DO) during the process was 8.20 mg / l and after without aeration it was reduced to 4.94 mg / l, it is acceptable; nitrate before aeration 1.13 mg / l and after 6.13 mg / l.
