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).

WHAT (& WHAT FOR): Lead is a metal often found in pipes, and in old paint (before it was banned in paint in the late 1970s). Before 1996, lead also found in vehicle fuel resulting in  soil contamination in many communities from both paint dust and vehicle pollution. 

HEALTH IMPACT: Lead is a neurotoxin and is known to have no safe blood lead level in children. 

Has been linked to:

1. Brain swelling, anemia, seizures, renal failure, reduced IQ, and ADHD

2. Damages brain development in children

3. Connected to behavioral problems like aggression and bullying, and internalizing problems such as depression and anxiety 

LOCAL IMPACT: Recent research in Santa Ana has shown that there is a disproportionately impact of solid lead contamination crisis on lower income, people of color communities. 

POSSIBLE RESPONSES: There are many ways to respond to lead contamination:

1. Providing special health care for children with high blood lead levels, and investigating possible sources of lead exposure in homes, daycares and school, playground, etc.

2. Implement strict housing policies where landlord and city housing officials are required to have lead inspections of homes for lead paint hazards (especially in low income, people of color communities)

3. Requiring a minimum reduction standard for lead paint in older homes 

4. Requiring blood lead level test as part of the routine check up for children (extremely important for children in low-income housing)

WHAT (& WHAT FOR): PFOAS are a group of large manufactured chemicals that are widely used in various everyday items. Often used in waterproof items and nonstick pans among other products.  They are used in a number of industrial processes. Improper disposal of the chemicals from industrial manufacturing has resulted in PFAS seeping down into the ground and into the water supply.  These chemicals are known to be forever chemicals that  do not degrade in the environment. 

HEALTH IMPACT: PFAS are known to be forever chemicals that cause weakened immune systems, increased cholesterol level, increased risk of testicular and kidney cancers, and decreased vaccine response in children. EPA has concluded that exposure to PFOA and PFOS over certain levels may result in developmental effects to fetuses during pregnancy (low birth weight) or breastfed infants (accelerated puberty, skeletal variations). 

LOCAL IMPACT: Both the State Water Board and the Santa Ana Water Board have initiated investigations. The PFAS investigation done by State of California Regional Water Quality Control Board reveals results that show PFAS concentrations above the current Notification Levels for drinking water. Santa Ana Water Board staff is currently working to identify potential sources of the contamination in the groundwater. 

POSSIBLE RESPONSES: 

1. Conduct wellhead treatment to treat PFAS impacted drinking water to levels below state-established PFOA/PFOS notification levels.

2.  Obtain a more comprehensive monitoring information on potential sources of PFAS

3. Set Effluent guidelines, develop analytical methods and issue water quality criteria for PFAS
