Poland
97%
of the population in 2023 was supplied
with drinking water in line with the EU legislation
High quality, safe and sufficient drinking water is essential for public health and well-being. The Directive EU 2020/2184 (recast Drinking Water Directive - DWD) is the EU’s main law regulating the access to and the quality of water intended for human consumption.
Is the drinking water supplied to the population of Poland compliant with the minimum water quality requirements of the EU legislation?
In 2023, 97% of the total population of Poland was supplied with drinking water meeting the minimum water quality standards set out by the recast Drinking Water Directive.

How many exceedances of drinking water quality standards were reported? What were the causes?
In 2023, 639 exceedances of drinking water quality standards were reported in Poland. The key causes of these exceedances are shown in Figure 2.

How many incidents related to drinking water are reported? What were the causes?
In 2023, 991 incidents related to drinking water, which lasted more than 10 consecutive days and affected at least 1,000 people, were reported in Poland. The key causes of these incidents for different sizes of water supply zones are shown in Figure 5.

Number of incidents
In 2023, 2.96% of Poland's population, corresponding to 36.7 million people, was affected by incidents. The share and number of the population affected for different size groups of water supply zones are shown in Table 1.

How many derogations from the established water quality standards were granted in Poland? On what grounds?
In 2023, 13 derogations from established drinking water quality standards were reported in Poland and 0.6% of the total population was affected by these derogations (~227,600 people), this is above the EU average of 0.13%. The derogations granted in 2023 were based on the grounds shown in Figure 7.

Notes
*The affected population by exceedances / incidents is reported by countries for unique combinations of water supply zone, parameter, period (end date - start date) and cause. Therefore, double-counting is theoretically possible if countries have reported the same population exposed to an exceedance or incident for multiple parameters, overlapping periods andmultiple causes. Therefore, the calculation considers only the maximum population that was affected in each WSZ by any exceedance / incident for all relevant parameters, periods and causes. This is a conservative method to capture the potential reach of the most significant events that occurred over the reporting period in each WSZ. The affected population is expected to be underestimated in cases where countries report similar types of exceedances / incidents (i.e. same parameter, period and cause) for different locations / sub-areas of the same WSZ, because such spatial separation within the WSZ cannot be known in advance and captured from the reporting results. The affected population in each country is the aggregation (sum) of the maximum affected population from all water supply zones in the country. The affected population in the EU is the aggregation (sum) of the affected population from all countries in the previous step.
