Note from the test report (in the German original): Stadtwerke Lich · Gesamthärte je Ortsnetz aus den Trinkwasseranalysen Mai 2026, deshalb ist nur der Monat angegeben. Dieser Wert gilt für das Ortsnetz Lich. Die anderen Ortsnetze laut gleicher Quelle: Arnsburg/Muschenheim 10,2 °dH, Bettenhausen 21,8 °dH, Birklar 6,2 °dH, Eberstadt 22,6 °dH, Langsdorf 7,2 °dH, Nieder-/Ober-Bessingen 8,3 °dH. Die Stadtwerke veröffentlichen hier nur die Härte in mmol/l; °dH ist daraus umgerechnet (1 mmol/l = 5,6 °dH). Weitere Stoffe nennt diese Quelle nicht.

Water at your own tap: The values describe the water the supplier delivers – not automatically the water at your tap. The water supplier is responsible up to the service connection (Hausanschluss); the building owner is responsible for the pipes beyond it. Lead can dissolve from lead pipes, leaded solder joints or old brass fittings, especially when water has stood in the pipes for a long time (stagnant water); this mainly affects buildings constructed before about 1973. If water has stood in the pipes for several hours, let it run until it comes out cool. If you suspect lead pipes, a lead analysis of the stagnant water by an accredited laboratory will help.

Background on household plumbing, not a measurement: in Lich, 48 % of buildings with living space were built before 1970, and a further 14 % between 1970 and 1979 (Zensus 2022, Statistisches Bundesamt, dl-de/by-2-0). (Zensus 2022) According to the German Environment Agency (Umweltbundesamt), lead pipes exist at most in houses built before 1973 – and by no means in all of them. Whether there are any in your house is known to the owner or a plumber. (UBA)

Water hardness in Lich in everyday life

At 9.5 °dH, Lich is in the hardness range “medium” (soft: below 8.4 °dH, medium: 8.4–14 °dH, hard: above 14 °dH).

Dose detergent for the hardness range “medium”.
As a rule of thumb, descale the kettle about every four to six weeks and the coffee machine as the manufacturer recommends.
A limescale protection device is not a must at medium hardness; regular descaling is often enough.

Frequently asked questions about tap water in Lich

Can you drink the tap water in Lich?

For Lich we have no values with a legal limit that we could compare. Stadtwerke Lich can give you reliable information.

How hard is the water in Lich?

The total hardness is 9.5 °dH – hardness range “medium”. Dose detergent for the hardness range “medium”.

Is there PFAS in the tap water in Lich?

The published analysis by Stadtwerke Lich that we evaluated gives no PFAS value. This does not mean there is no PFAS in the water; there is simply no figure for it. Since 12 January 2026, a limit of 0.1 µg/l has applied to the sum of PFAS-20. The supplier can tell you whether PFAS was measured and with what result.

Do I need to filter my tap water in Lich?

Based on the verified supplier values, a filter is not necessary. It can make sense if you do not like the taste. If you suspect lead pipes in an old building, a filter does not help; a laboratory analysis at the tap does – that is a question of the household plumbing, not of the water leaving the works.

WaterScore

Total (provisional)81 / 100
Data timeliness100 / 100
Data quality66.7 / 100

Data coverage: 0 of 7 core parameters. Not in the test report: Nitrate, Nitrite, Lead, Copper, Arsenic, Uranium and PFAS (sum). Missing parameters are neither estimated nor counted as harmless: the score is based only on the values available and is therefore provisional. It is not a health assessment and says nothing about the water beyond the service connection. Methodology v4: how we calculate the WaterScore.
