1. Long-term threats, legacy of mining
- Unstable old salt mines below Stassfurt that have to be monitored and water flows have to be management to prevent ground movement
- so far, more than 800 buildings, including an 500-year old church had to be demolished. Currently, ground movement is under control
- 27 waste heaps and contaminted sites within the city that contain many very hazadous chemical compunds. They were never properly cleaned up

2. Long-term threats, ongoing causes
- by-products of salt mining and refining are collected in large landfills that leak salt into sorrounding areas. There are no plans how these landfills can be remediated, they have to be mananged indenfinitely
- soil erosion of arable land around the city by high intensity farming of crops for livestock production and bioenergy
- toxic waste produced by waste incarceration plant is pumped into former salt mining caves where it solidifies and becomes impossible to recover

3. Short term threats
- explosion in bionenergy plant in 2020
- leakage of ammonia at public street in 2014
- pollution of river bode with ammonia and chloride by CHIECH Soda, massive fish kills every summer
- air pollution, cause unknown, probably mostly by metalworks industry

Staßfurt is a small city in the East German Bundesland Saxony-Anhalt with about 24 thousand inhabitants. Like many cities and villages in the area, it faces huge demographic problems: The population is shrinking rapidly, consists mostly of older people, unemployment is high, percentage of highly educated people is low. The city has a long history of salt mining that goes back to the 13th century. Many inhabitants proudly refer to Staßfurt as the "Cradle of potash-mining" ("Wiege des Kalibergbaus"). Unfilled salt mining shafts that were flooded by groundwater had to be abandoned and started to cave in. Over 800 buildings in the city center had to be demolished because of instabilities, among them a 500-year old church. Nevertheless, salt mining and a metallic industry that developed alongside it is still the largest economic sector in Staßfurt. The city is still permeated by an old mining culture that becomes visible in traditional festivals, clubs (Bergmannsverein e.V. Staßfurt) and the playing of traditional miner's song on offical occasions (Steigerlied).

The authors offer a review of themes within occupational health and environmental public health surveillance over the past decade. In reviewing the history of public health surveillance, the authors highlight key acts of Congress in the 1970s that have made the development of “modern” occupational health and environmental health surveillance possible—but which also failed to develop into a cohesive and well-connected data management systems across federal agencies. Separate agencies were tasked with different data collection, management and intervention tasks in ways that fragmented the surveillance system to the point of ineffectiveness.

The authors argue that effective surveillance for occupational and environmental health demands development of a clear purpose for collecting data and having the data available to make meaningful analysis possible. They turn to the CDC’s childhood lead prevention program to demonstrate these points.

Training in programming skills takes a new prominence as an area of tech-for-good: previously, there was a great deal of focus on k-12 and university education to teach programming skills in order to increase social mobility and access to high-paying jobs, or just because STEM education is a good in some stories, or to increse diversity in tech fields as an end unto itself. 

Now re-skilling, in this case through a private corporation's CSR and advertisement campagin for new paying membership, is taking on new significance as massive layoffs and furloughing has left people at home, responsibilized to find a new job. Meanwhile, the tech industry is in quite a few cases hiring as reliance on digital connectivity for things that were once done in-person has increased with quarantining. 

By matching purchases of Pro Membership of their programming training with five donation subscriptions, this private business is casting itself as socially responsible. They are re-skiling people who have been furloughed or laid off during the pandemic and this allows them to be competitive for jobs that are still in demand as programmers. Programming and tech industries are the most resilient in a situation of social distancing, as everyone more or less fully relies on digital connectivity for interaction, and this company is capitalizing on that situation to increase its paying membership while boosting its image of social responsibility. 

As a purchaser of Pro Membership, I'm doing a good because I'm "unlocking" the donations to 5 people who get the opportunity to receive training in a new skill through a premium version of a free platform, and this might get them employment.
