US groundwater protection regulations `not comprehensive enough`
Groundwater protection is the responsibility of everyone including the chemical industry. An energetic group of state and federal groundwater agencies, industry, environmentalists and other stakeholders, however, has made it a key area of their focus. The Ground Water Protection Council (GWPC) is a nonprofit Section 501(c)(6) organization dedicated to promoting and ensuring the use of best ...

The Federal Interim Groundwater Quality Guidelines
The Federal Interim Groundwater Quality Guidelines was developed by federal authorities to facilitate the assessment, remediation and risk management of federal contaminated sites which are under the funding of the Federal Contaminated Sites Action Plan (FCSAP). The guidelines are applicable in Canada until the time when groundwater guidelines will be developed. FCSAP was established to identify ...

Oman: Guidelines for groundwater abstraction
Groundwater is a precious resource in Oman, which is designated “National Wealth” by Royal Decree. The concession agreement between Petroleum Development Oman (PDO) and the government gives PDO the right to explore and use groundwater. So far PDO has used groundwater only for maintaining camp operations. As the field is maturing, PDO is moving to enhanced oil recovery techniques, such ...

Regulatory Aspects of Direct Potable Reuse in California
Introduction California's water supplies are derived from a variety of sources, including local and imported surface water, groundwater, desalinated seawater, and recycled water. Water resources are becoming limited due to population increases, droughts, and reductions in imported water allocations. Furthermore, global climate change may exacerbate the problem in the future. Water recycling for ...

Study: Coal-Fired Power Plants Are Polluting Groundwater
Environmental groups are pushing for tighter regulation and enforcement of EPA rules A new study shows that of the 265 coal-burning power plants it studied in the United States, 241 have dangerous levels of toxic metals in the groundwater around them, based on Environmental Protection Agency (EPA) standards. The figure, which comes to 91% of the plants, was derived only from plants that must ...

Statistische Aspekte bei der Auswertung von Grundwasserqualitätsdaten nach den Vorgaben der EU-Wasserrahmenrichtlinie (WRRL)
Abstract On 22. December 2000, directive 2000/60/EC, the Water Framework Directive, entered into force by being published in the official journal of the European Communities. Apart from comprehensive regulations in the field of water policy, this directive inlcudes provisions for the evaluation of groundwater quality data. The directive stipulates that data should be aggregated so that the ...

Groundwater governance: explaining regulatory non-compliance
This paper explores the non-compliance of water users through a case study of groundwater resources in the Gulf Islands (British Columbia (BC)) and the San Juan Islands (Washington). The research challenges two assumptions: that local regulations can easily incorporate scientific research, which in turn leads to sound on-the-ground management; that sound on-the-ground management translates into ...

Common Treatment Train for Inorganics
A treatment train is the combination of different treatment technologies. A system diagram of a common treatment train for inorganics is illustrated below. Metal contaminated soil is treated using the combination of electrokinetics and phytoremediation. Electrokinetics is used to remove metals from deep soil and ground water. A low density direct current is applied to mobilize charged species, ...

Evolutionary network flow models for obtaining operation rules in multi-reservoir water systems
Obtaining operation rules (OR) for multi-reservoir water systems through optimization and simulation processes has been an intensely studied topic. However, an innovative approach for the integration of two approaches – network flow simulation models and evolutionary multi-objective optimization (EMO) – is proposed for obtaining the operation rules for integrated water resource ...

Who Owns Groundwater?
California’s drought underscores the need to improve how the state - and the rest of us - divvy up a resource in demand. Grapevines march across wires strung along rolling hills, their little trunks improbably supporting heavy black fruit. Cindy Steinbeck’s family has been farming this land since 1920. They grow Zinfandel, Viognier, Cabernet, Merlot, and Petite Syrah grapes but are ...

Pennsylvania's US Environmental Standards on Vapor Intrusion
Vapor intrusion occurs due to volatile substances found in groundwater or soil, and they find their way into buildings inhabited by human beings. Vapor phase intrusion of the volatile substances is a threat to human health. The Pennsylvania Department of Environmental Protection (PADEP) provides guidelines and standards used for the evaluation of vapor intrusion under site-specific standard (SSS) ...

Development of recreational water spray ground design regulations in New York State, an engineering approach
The New York State Department of Health developed regulations for the design and operation of spray grounds to address the potential for recreational water illnesses associated with this type of venue. The water treatment component of the new regulation was based on a first-principles approach to address the unique challenges of spray grounds. The regulation departs from traditional ...

EPA Releases Interpretive Statement on whether CWA NPDES Permit Program Applies to Releases of a Pollutant from a Point Source to Groundwater
On April 23, 2019, the U.S. Environmental Protection Agency (EPA) announced it was making available its Interpretive Statement addressing whether the Clean Water Act’s (CWA) National Pollutant Discharge Elimination System (NPDES) permit program applies to releases of a pollutant from a point source to groundwater (Interpretive Statement) for comment. 84 Fed. Reg. 16810. EPA is issuing the ...

In Situ Physical/Chemical Treatment for Ground Water and Leachate
The main advantage of in situ treatments is that they allow ground water to be treated without being brought to the surface, resulting in significant cost savings. In situ processes, however, generally require longer time periods, and there is less certainty about the uniformity of treatment because of the variability in aquifer characteristics and because the efficacy of the process is more ...

CL-Out Completes Remediation After Stalled Natural Attenuation
Investigation of an industrial dry cleaners near Philadelphia, Pennsylvania found concentrations of breakdown products of PCE in the soil and ground water. The parent PCE presumably was reductively dechlorinated to TCE, DCE and vinyl chloride. However, since the daughter products DCE and vinyl chloride are more readily degraded under aerobic conditions, the breakdown was incomplete and natural ...

North Carolina Groundwater Standards
The North Carolina Groundwater Standards defines the maximum permissible contaminant concentration in groundwater that does not cause harm to humans. Exceeding such specified concentrations poses a threat to human health. Therefore, it serves to prevent contamination of North Carolina's groundwater, protect public health, and allow for the proper management of the state's groundwater. These ...

Sustainability of Arizona’s few remaining perennial streams.
Mother Nature made water simple. In general, water comprises a continuum in whatever phase or phases it may occur. If you take some here, you have less somewhere else. Arizona law does not readily account for this simple concept; rather it arbitrarily divides water into different classes to be regulated as if the classes were somehow distinct and separable. This creation of different classes of ...

Alberta Tier 2 Soil and Groundwater Remediation Guidelines
The Alberta Tier 2 guidelines for soil and groundwater remediation are used when considering site-specific conditions implemented through modifying Tier 1 remediation guidelines. It is also applied to remove exposure pathways that do not apply to specific sites. Compared to Tier 2 remediation guidelines, a lot of information about a site is needed to implement Tier 2 guidelines. The required ...
