The Uk

Some 1% of the UK population derives their potable water from 140,000 private water supplies (PWSs) regulated by Local Authorities. The overwhelming majority of these are very small domestic supplies serving a single property or a small number of properties. Treatment for such supplies is rudimentary or non-existent and their microbiological quality has been shown to be poor in every published study to date. Private water supplies serving commercial enterprises such as hotels, restaurants, food production premises and factories are more frequently treated and subject to closer regulation in the United Kingdom. As a result, it has been assumed that these larger commercial supplies are less likely to experience elevated faecal indicator and pathogen concentrations at the consumer tap which have been observed at small domestic supplies. This paper reports on intensive monitoring at seven commercial private water supplies (six of which were treated) spread throughout the UK serving hotels, holiday parks and food production enterprises. Daily sampling of ‘potable’ water, both at the consumer tap and using large volume filtration for Giardia and Cryptosporidium spp. was conducted over two six week periods in the spring and autumn of 2000. This allowed the effects of short term episodic peaks in faecal indicator and pathogen concentration to be quantified. All the supplies experienced intermittent pathogen presence and only one, a chlorinated deep borehole supply, fully complied with UK water quality regulations during both periods of sampling. Poor microbiological water quality typically followed periods of heavy rainfall. This suggests that the design and installation of such systems should be undertaken only after the likely range of raw water quality has been characterised, which requires a thorough understanding of the effects of flow and seasonality on raw water quality. There is no reason to suspect that the monitored sites are uncharacteristic of other commercial supplies and the results reinforce public health concerns related to domestic supplies. Furthermore, the pattern of contamination is highly episodic, commonly lasting only a few days. Thus, the relatively infrequent regulatory monitoring of such supplies would be unlikely to identify the poor water quality episodes and does not provide the data necessary for public health protection. Although some statistical relationship was found between faecal indicator organisms and the presence of pathogens, the use of FIOs in assessments of regulatory compliance may not always provide a reliable measure of public health risk, i.e. indicator absence does not preclude pathogen presence. The results of this study suggest that a risk assessment system similar to the WHO ‘Water Safety Planning’ approach might offer a more appropriate regulatory paradigm for private water supplies.

With 80% of Florida’s residents living within 10 miles of the coast, Florida’s aquatic resources are directly affected by urbanization. The intent of this new 6-page publication of the UF/IFAS Department of Soil and Water Sciences is to describe the urban nitrogen cycle for a non-technical audience. Ultimately, this document is intended for individuals working in urban environments and concerned about nutrient pollution and water quality issues, but do not have a technical background and want to improve their understanding of nitrogen cycling.

Sustainable Food Production

The agricultural community has a challenge of increasing food production by more than 70% to meet demand from the global population increase by the mid-21st century. Sustainable food production involves the sustained availability of resources, such as water and energy, to agriculture. The key challenges to sustainable food production are population increase, increasing demands for food, climate change, and climate variability, decreasing per capita land and water resources. To discuss more details on (a) the challenges for sustainable food production and (b) mitigation options available, a special issue on “Water Management for Sustainable Food Production” was assembled. The special issue focused on issues such as irrigation using brackish water, virtual water trade, allocation of water resources, consequences of excess precipitation on crop yields, strategies to increase water productivity, rainwater harvesting, irrigation water management, deficit irrigation, and fertilization, environmental and socio-economic impacts, and irrigation water quality. Articles covered several water-related issues across the U.S., Asia, Middle-East, Africa, and Pakistan for sustainable food production. The articles in the special issue highlight the substantial impacts on agricultural production, water availability, and water quality in the face of increasing demands for food and energy.

The Impact

The food–energy–water (FEW) nexus is, by definition, a “wicked problem” in that potential solutions in one sector may inadvertently create perverse effects in another. For example, rapid population growth in conjunction with increasing urbanization will add additional stress to current pressures on the world’s FEW resources. Water scarcity will increase challenges in providing plentiful foods, as well as clean, potable water. Water is also critical to energy production—and conversely—energy is needed to deliver clean, safe water. Extant and projected demand for FEW creates an intertwined problem of supply and demand and new policy considerations for managing the nexus. This study examines the FEW policy tradeoff preferences of the public in California, Idaho, Oregon and Washington states, using survey data collected in 2018. More specifically, this study examines the impact of demographic control variables, FEW knowledge, and environmental values and beliefs on hypothetical tradeoffs between FEW policy preferences. Findings suggest that those respondents that believe in human-caused climate change and with higher new ecological paradigm (NEP) scores were more supportive of water quality issues versus hydroelectric energy production, rural solar energy development versus limiting rural solar development for food production, and water quality over food production for a growing population.

AbstractThe North Carolina Agriculture Survey was designed to estimate the willingness to pay for agricultural research and extension programs. We find that North Carolina households are willing to pay between $218 and $401 million for food production programs and between $251 and $698 million for water quality programs annually. We find evidence of divergent validity and differences in the willingness to pay estimates from the single-bound and multiple-bound data.
