Surface water
The text below is based on the chapter Surface water published in yearbook Prague Environment 2006
The water quality assessment is every year performed according to the Czech Standard ČSN 75 7221 “Classification of Surface Water Quality”. The standard was made more exact on the basis of practical experience and at the same time it was closer harmonised with the surface water classification, which is in use in the EU Member States. The standard is focused on a uniform determination of quality classes of flowing surface water – the classification, which serves for benchmarking of water quality at various locations and in various times. Surface water is classified into five classes based on quality. Water quality is classified on the basis of check results acquired over a longer continuous period. The shortest period assessed is one year. It is recommended, at monitoring frequency of 12 samples taken per a year, to make the classification of the check results for a two-year period in order to have 24 values measured (1999–2000) at least for the characteristic value calculations. If there are less than 11 values – results of water quality checks – the classification pursuant to the standard mentioned cannot be carried out. Water quality is assessed for separately in every single indicator. The assessment indicators evaluated are sorted into five groups. The indicator of the worst quality determines the entire group value. Then the group of the indicators of the worst classification value determines the overall classification of quality of water in a particular watercourse.

Evaluation of hydrometric profiles of the national network located on the City of Prague territory and in its nearest vicinity
In 2005 there were in total 333 hydrometric profiles monitored within the National Monitoring Network of Water Quality in Watercourses.
In Prague and in its closest vicinity there are four hydrometric profiles of the National Network monitored located on the Vltava River – Vrané, Podolí, and Libčice, and one located on the Berounka River – Lahovice. The measurements of selected indicators have been performed continuously since 1963. In 2005 the numbers of substances measured at the profile Vltava River – Vrané were 106, at the profile Vltava River – Libčice 105, at the profile Vltava – Podolí 82, and at the profile Berounka River – Lahovice, 57, respectively. Sampling frequency was twelve times per year and for the indicator AOX six times per year.
According to the Czech Standard ČSN 75 7221 the classification in chlorophyll was the worst evaluated indicator at all the profiles. It reached class V at Berounka River – Lahovice, at Vltava River – Podolí and Vltava River – Libčice class IV. The best evaluation of class III was detected at the Vltava River – Vrané profile. Also total phosphorus fell into class III at all the profiles.
At the Vltava River – Vrané nad Vltavou was the best evaluated profile because more than a half of 38 indicators measured reached merely class I, 11 substances fell into class II, five substances were in class III, and none of the indicators was classified class IV and V.
At the Vltava River – Podolí 20 indicators of 38 measured fell into class I, 14 indicators reached class II, and three indicators attained class III. Besides the aforementioned total phosphorus also BOD5 and CODCr. The only indicator falling into class IV was chlorophyll.
At the Vltava River – Libčice 18 indicators out of 38 were classified class I, 13 substances reached the limit values for class II, five for class III – total phosphorus, AOX, VOC, CODCr, BOD5, chlorophyll and faecal coliform bacteria were classified class IV and no indicator fell in class V.
At the Berounka River – Lahovice similar substances were classified falling inot higher classes as at three profiles at the Vltava River. Besides chlorophyll in class V, these were IM 105 °C, BOD5, TOC, and total iron in class IV, AOX, CODCr, CODMn, total phosphorus, coliform bacteria, and lead falling into class III.
Pursuant to the Order of the Government of the Czech Republic No. 61/2003 Code out of the substances enlisted in the Order the numbers measured at respective profiles were 62 at the profile Vltava – Libčice and the profile Berounka – Lahovice, 60 at the profile Vltava – Vrané and at the profile Vltava – Podolí. While assessing profiles pursuant to the Order at every profile the immission standards for surface water were exceeded at total phosphorus, IM 105 °C, and pH. The highest frequency of exceedance was recorded at the profile Vltava – Libčice, for 10 indicators out of 62 measured, including faecal bacteria and faecal-coliform bacteria. The cleanest profile of the mentioned ones was the profile Vltava – Podolí where solely 6 measured substances did not meet the required immission standards, that is 10 %.
