MEP informed the media about the state of the environment in China in the first six months. 
According to Luo Yi, Director General of Environmental Monitoring Department under MEP, the national environmental monitoring network continued to monitor various environmental factors in the first six months of the year, which included ambient air, acid rain, surface water, centralized drinking water sources, nearshore sea areas, and urban noise. Air quality was monitored in a total of 1,436 sites under national monitoring program in 338 cities at prefectural level and above (including the seats of prefectures, autonomous prefectures, and leagues); acid rain was monitored in 1,011 sites in 470 cities (districts, counties); surface water quality was monitored in 956 sections (sites) under national monitoring program in the seven major waters, and rivers in southwest and northwest regions as well as Zhejiang and Fujian provinces; the quality of centralized drinking water sources was monitored in 325 cities at the prefectural level and above; seawater quality was monitored in 301 sites in the nearshore sea areas; and acoustic environment quality was monitored in the functional areas of 291 cities. 
Luo said that in accordance with Ambient Air Quality Standard (GB3095-2012), the ratio of attainment days ranged between 5.5% and 100% and averaged out at 72.7% in 338 domestic cities at the prefectural level and above (including the seats of prefectures, autonomous prefectures, and leagues). The ratio of nonattainment days averaged out at 27.3%, including 18.7% of days with records of slight pollution, 5.2% of days with moderate pollution, 2.7% of days with heavy pollution, and 0.7% of days with severe pollution. The main pollutant was PM2.5. 
The ratio of attainment days ranged between 21.1% and 98.9% and averaged out at 68.0% (up 6.9 percentage points year on year) among the 74 cities scheduled to implement the new air quality standards in Phase I, including cities in Beijing-Tianjin-Hebei region, Yangtze River delta, and Pearl River delta as well as other municipality directly under the Central government, provincial capital cities, and cities separately listed in State plans (hereinafter referred to as the 74 cities). The main pollutant was PM2.5 in most of the nonattainment days, and then O3 in less nonattainment days. The air quality of Beijing-Tianjin-Hebei region, Yangtze River delta, and Pearl River delta turned better compared with the same period last year. The last 10 cities in the ranking of the 74 cities by air quality (74th to 65th) were Baoding, Xingtai, Zhengzhou, Tangshan, Shijiazhuang, Hengshui, Jinan, Handan, Shenyang, and Taiyuan. The top 10 cities in the ranking by air quality (1st to 10th) were Haikou, Lhasa, Huizhou, Zhoushan, Xiamen, Zhongshan, Zhuhai, Shenzhen, Kunming, and Fuzhou. 
One hundred and sixty-four cities out of the 470 domestic cities which monitor acid rain actually observed acid rain in the first six months. The ratio of cities with records of average acid rain (mean pH value<5.6), of cities with records of fairly serious acid rain (mean pH value<5.0), and of cities with records of serious acid rain (mean pH value<4.5) dropped 4.5, 5.8 and 3.2 percentage points respectively from the same period last year. The nation-wide acid rain pollution was mitigated in general. Acid rain was distributed mainly to the south of the middle and lower reaches of Yangtze River, which include the majority of Zhejiang, Jiangxi, Fujian, and Hunan provinces, southwestern part of Chongqing Municipality, the Yangtze River delta, and Pearl River delta. The acid rain distribution area accounted for about 7.6% of the national territory. Specifically, the distribution area of fairly serious acid rain accounted for 1.6%. Either area shrank 2.4 percentage points year on year. The acid rain frequency averaged out at 14.8% on a national scale. The main type of acid rain was still caused by sulfuric acid. 
In the first six months, of the 956 sections monitored under national surface water monitoring program, 2.7% attained Grade I national standard, down 1.1 percentage points year on year; 31.2% attained Grade II standard, up 3.2 percentage points year on year; 30.2% attained Grade III standard, down 0.8 percentage point year on year; 18.9% attained Grade IV standard, down 2.0 percentage points year on year; 6.7% attained Grade V standard, up 1.1 percentage points year on year; and 10.3% failed Grade V standard, down 0.4 percentage point year on year. The main pollutants were CODCr, TP and NH3-N. Excessive heavy metals were recorded in eight sections (sites) under national surface water monitoring program on 18 occasions. The main pollutants were arsenic and mercury. The eight sections were distributed in Yunnan (2), Jilin (2), Guangdong (1), Jiangsu (1), Fujian (1), and Sichuan (1).
From January to June, 17.19 bn. t of raw water was taken from centralized drinking water sources in 325 cities at prefectural level and above, providing drinking water for 326 mil. populations. Of those, 16.719 bn. t attained water quality standard, accounting for 97.3% of the total. Of the 898 centralized drinking water sources, 558 were surface water sources, of which 534 attained water quality standard, accounting for 95.7%. The main pollutants were TP, NH3-N, and Mn. The remaining 340 were groundwater sources, of which 296 attained water quality standard, accounting for 87.1%. The main pollutants were Fe, Mn, and NH3-N. 
In the first six months, of the monitoring sites in nearshore sea areas, 35.9% attained Grade I national standard for seawater quality, 31.2% attained Grade II standard, 7.6% attained Grade III standard, 8.0% attained Grade IV standard, and 17.3% failed Grade IV standard. The ratio of sea areas attaining Grade I and II standards went up 0.3 percentage point year on year, that of sea areas attaining Grade III and IV standards went up 2.7 percentage points, and that of sea areas failing Grade IV standard dropped 3.0 percentage points. The main pollutants were inorganic nitrogen and active phosphate. 
In the first six months, of the 291 cities which monitor the acoustic environment quality of functional areas, the daytime attainment rate of all sorts of functional areas averaged out at 92.7%, and the nighttime attainment rate of them averaged out at 74.3%. Compared with the same period last year, both of the rates were improved in most cities stated above, and the acoustic environment quality of functional areas in provincial capital cities was below the national average.
