The lack of clean water distribution by local water service (PDAM) of Palangka Raya city is the major reason for people around the final processing site/landfill (Tempat Pemrosesan Akhir) at Km 14 to use groundwater for their daily life. The landfill may cause pollution over groundwater known as leachate, which commonly unnoticed by its users. This study aims at assessing the quality of groundwater in that area. The groundwater was taken at different distances from the site in three rainless-days. The physical, chemical and biology parameters of groundwater are observed in the field (in situ) and analyzed in the laboratory, refers to water quality standard of Class I, according to Government Regulation No. 82 of 2001 and Minister of Health Regulation No. 32 of 2017. Public opinion on that issue is cached through interview. The results showed that the groundwater around the landfill in three rainless-days was harmless to be consumed as drinking water, and did not exceed the water quality standards stipulated by government in term of odorless, tasteless, and colorless. Some indicators also show that the groundwater meets the specified quality standards, i.e. TDS (17-68.14 mg/L), DHL (17,15-69.39 ?s), turbidity (0.11-2.50 mg/L), iron (0.227-0.71 mg/L), manganese (<0.0123-0.02 mg/L), coliform (<1.8-280 MPN/100 ml), while Pb and H2S were not detected. From community side, there are no any health complaints arise as long as they use the water.

Scioto River

<i>Abstract</i>.—A 37-year series of standardized fish assessments in the Scioto River (Ohio, USA) since 1979 coupled with historical information documents a near complete recovery from heavily polluted conditions in the late 19th and early to mid-20th centuries. Nearly 100 fish species were extirpated downstream from the city of Columbus (Ohio, USA) by sewage and industrial pollution. The 1972 amendments to the Federal Water Pollution Control Act (Clean Water Act) mandated the control of sewage and industrial pollution. Reductions in loadings of untreated or poorly treated sewage were incremental. Full recovery to near-prepollution composition and abundance took more than two decades after advanced wastewater treatment was achieved. Unpolluted tributaries served as recolonization sources for populations of extirpated species. These positive changes extended across all fish assemblage members as evidenced by increased values of the Ohio index of biotic integrity; modified index of well-being; native species richness, density, and biomass; and the reduced incidence of external anomalies on fish. These restoration successes and their documentation were facilitated by the Clean Water Act that set forth the goals for water quality standards and treatment technology for reducing water pollution and conducting baseline and follow-up monitoring. An important lesson learned was that serious doubts that existed in the 1970s about the feasibility of advanced wastewater treatment technology and the attainability of water quality standards in an effluent dominated river were completely erased by the demonstrated improvements in the fish and macroinvertebrate assemblages in the Scioto River. The extent of improvements in recreational opportunities have tracked that of the biota by an increased use for fishing, canoeing, kayaking, and related forms of recreation. However, maintaining these improvements will require continuation of high levels of wastewater treatment and water quality standards. A growing human population that is forecast to increase by one-half million persons by 2050 makes maintaining the currently high levels of biological integrity a continuing challenge. Given the lessons learned with the mosaic of stressors in the Scioto River over the past 150 years, we believe this challenge can be met successfully.

The determination of water quality status was needed as a reference to monitor water pollution. The purpose of this study was to determine the concentration of ammonia, nitrate, and phosphate in Depapre waters, Jayapura Regency. Sampling was carried out in October 2017 across five research stations, then the results were compared with water quality standards based on KEPMEN-LH No. 51 Tahun 2004 for marine biotas. Based on the analysis of water quality in Depapre waters obtained the following results are the ammonia content ranges from 0.8 to 11.6 mg/L, the content of nitrate ranged from 0.009 to 0.54 mg/L, and the phosphate content ranged from 0.016 to 1.19 mg/L. These results indicate that the ammonia, nitrate and phosphate concentration in Depapre Waters have exceeded the water quality standard. The concentration of ammonia, nitrate, and phosphate is high enough and endanger the lives of marine biotas.

Abstract Kampar River, Siak River, and Rokan River have different watersheds, and the water from these rivers is not interconnected. The results of this study can be used as a basis for managing aquatic resources in the Kampar River, Siak River, and Rokan River, Riau Province, Indonesia. This research was conducted in April 2017 – March 2018. The collection and measurement of water quality for each river consisted of three stations which were carried out based on SNI through the survey method twice, namely in the dry season and rainy season. The observed water quality parameters include physical, chemical, and biological parameters. The results of the next analysis are calculated using the STORET method using a value system from the United State-Environmental Protection Agency (US-EPA) which is adjusted to the Class III Water Quality Standard based on PP. 22 of 2021. The results of the analysis of the rain index value in the highest dry season is a score of -44 on the Rokan River, classified as class D with a score of -31 heavily polluted. The STORET score in the Kampar River and Siak River obtained -24, each classified as Class C, is included in the moderately polluted category. Meanwhile, in the rainy season the pollution index with the same pattern is highest in the Rokan River -40, then Kampar River, and Siak River each -20. The water quality standard used in this study is class III because it still supports fish farming activities. Based on Government Regulation Number 22 of 2021 concerning water quality standards, class III is water whose designation can be used for freshwater fish aquaculture, animal husbandry, and gardens irrigation. The Storet method is carried out by collecting water quality data and measuring data from each water parameter compared to the value of class III water quality standards.

The quality of ground water for drinking water needs is based on physical, chemical and biological parameters of Romang Polong. The researcher took 5 kinds of water as samples based on land use by applying the Storet method. The water sample was tested in the field and analyzed in the laboratory. The results obtained are compared with the specified based on criteria of water quality which indicated that groundwater in the Romang Polong is suitable to be used as drinking water quality standards at the point 2, 3, and 4. However, at the point 1 and 5 are not feasible to be used as drinking water quality standards. But, it is still feasible to use for household needs such as bathing and washing. It might be happened because the physical, chemical, and biological parameters exceeded the maximum permissible threshold based on the drinking water quality standard according to Minister of Health of the Republic of Indonesia No. 492 / MENKES / PER / IV / 2010.
