“Going into the future, we commit ourselves to testing our drinking water sources every three years. We are obligating ourselves to do that,” superintendent Marion Martinez said last week, according to the Press & Sun Bulletin of Binghamton. She said that while there was no legal testing requirement from New York state or the federal government, “we have a moral requirement”. … [Read more...] about Alarm over lead found in drinking water at US schools

That fact sheet said that the department asks residents to flush lines before a six-hour test period but doesn’t ask them to flush lines before filling sample bottles, something it felt the Guardian did not effectively explain in a January story. The water department also said federal compliance testing is only a “small fraction” of overall lead testing, that it “educates customers in high-risk areas” about ways to reduce lead exposure. … [Read more...] about Water departments to change lead-testing methods after investigation
Several cities do correctly follow EPA guidance on testing, according to documents provided to the Guardian, including: Cincinnati, Ohio; Jacksonville, Florida; Louisville, Kentucky; and Mobile, Alabama. Several said they intend to change protocols when they next test, including Mount Pleasant, South Carolina; Buffalo, New York; Worcester and Boston, Massachusetts; Lewiston, Maine; and the Rhode Island and Maine health departments. Chicago stopped aerator removal and pre-flushing by 2012. … [Read more...] about At least 33 US cities used water testing ‘cheats’ over lead concerns
Alice fell down- down- down- deep into the earth, following the white rabbit. Curiouser and curiouser she thought, in this underground wonderland the walls are made of sparkly gypsum - CaSO4.2H2O (with apologies to Lewis Carroll). It has been suggested that the author’s vision of Alice falling down a deep vertical hole into an underground land was inspired by natural geological events, notably subsidence at Ripon in North Yorkshire. There is a connection between the author, the city of Ripon, and dramatic subsidence that occurred at Ure Lodge, where the alleged model for the published ‘Alice’ illustrations used to live. Beneath this area, the gypsum has a water-filled cave system within it, but gypsum dissolves quickly so that the caves enlarge and commonly collapse. Collapse at Ure Lodge has continued to the present day. It recently caused the destruction of four modern garages and the evacuation of several houses, including the Lodge itself. Subsidence in Ripon, and … [Read more...] about Are humans causing more sinkholes?
Elsewhere in the US, sinkholes are common in Texas, Alabama, Missouri, Kentucky, Tennessee and Pennsylvania. In Britain, the BGS says the carboniferous limestone of the Mendip Hills, the north of the South Wales coalfield, the Peak District, the Yorkshire Dales, the northern Pennines and the edges of the Lake District all host well-developed karst landscapes. Karstic features are also common in the UK on the chalk of south-east England, on salt in the centre and north-east of the country, and particularly on the gypsum that underlies parts of eastern and north-eastern England, especially around Ripon and Darlington, and in the Vale of Eden. … [Read more...] about What are sinkholes and what causes them?
