Geary County rural water district 4 gets the red out!
Geary County RWD 4 is a public water system located approximately three miles northwest of Junction City, on the east side of Milford Reservoir. The system is supplied with water from two wells located in the Rolling Meadows Golf Course at the south end of the district. The district currently has about 320 meters and produces approximately 70,000 gallons per day during colder months and about ...

Case study - Ozone sparging closure of an industrial VOC spill site adjacent to a water supply well site
Description An undocumented surface spill at an active manufacturing facility located adjacent to a public water supply well field released chlorinated volatile organic compounds (PCE, and its breakdown products: TCE, c-DCE, and VC) into soils and groundwater. The driver for site cleanup was three water supply wells located 200 feet downgradient of the site bounds. The chosen endpoint ...

MP 1 pump indispensable when measuring water quality - Case Study
Good surface and groundwater quality means sustainable development of plants, animals, and reliable drinking water. To guarantee this quality, a policy has been formulated in the Water Framework Directive which must be observed by all EU Member States. Due to the integration of various European water quality directives, the European countries are on the same page in terms of water-related issues, ...

Elisabeth orphanage "kinderen van India" - Case Study
The Dutch based foundation "Kinderen van India" has set up an orphanage in 1989 in Pendra Road in the province Chhattisgarh (central India). The last two years the number of cases of waterborn diseases increased sharply. In particular the number of infectious diseases such as typhoid fever has risen sharply. The drinking water is extracted from a well located on the property. This source should ...

Quantitative analysis of microbial contamination in private drinking water supply systems
Over one million households rely on private water supplies (e.g. well, spring, cistern) in the Commonwealth of Virginia, USA. The present study tested 538 private wells and springs in 20 Virginia counties for total coliforms (TCs) and Escherichia coli along with a suite of chemical contaminants. A logistic regression analysis was used to investigate potential correlations between TC ...

Condition assessment survey of onsite sewage disposal systems (OSDSs) in Hawaii
Onsite sewage disposal systems (OSDSs) are the third leading cause of groundwater contamination in the USA. The existing condition of OSDSs in the State of Hawaii was investigated to determine whether a mandatory management program should be implemented. Based on observed conditions, OSDSs were differentiated into four categories: ‘pass’, ‘sludge scum’, ...

Why You Should Monitor Groundwater?
What is groundwater? Groundwater is water that is stored below the earth’s surface. When rain or other sources of water come into contact with the ground, the majority of it travels below the surface. Though much of this moisture is then absorbed by plants or returned to the atmosphere (through infiltration), some water will travel deeper beneath the surface – where it reaches and ...

Water penetration problems
Water penetration problems effect one out of every five acres in California (about 20 percent of the farm land) and it’s estimated that this costs growers $20 to $1,200 per acre. This problem is definitely worth taking a close look at since its quiet common in the central San Joaquin Valley. A more appropriate term to describe water entering the soil at the surface is infiltration. ...

Design Considerations for Multilevel Monitoring Wells
Untitled Document ABSTRACT Much has been written about the advantages of multilevel (multiport) monitoring wells over clustered or nested monitoring wells, however, there is little published information that provides helpful hints and 'dos and don'ts' for planning successful multilevel well projects. This paper discusses the differences in both design and construction ...
