Lazne Petrov - mineralni pramen
V Petrove u Straznice byla sirna mineralni voda (obsah H2S > 2 mg/l) pro lecebne ucely vyuzivana jiz ve stredoveku, kdy se o petrovske mineralni vode zminuje Tomas Jordan v publikaci "Kniha o vodach hojitedlnych neb teplicech moravskych" z roku 1580. Lazne byly oblibene jeste v 70. letech dvacateho stoleti. K jejich upadku a postupnemu zaniku doslo v souvislosti se vznikem lazenskeho provozu v Hodonine (oba provozy spadaly pod OUNZ Hodonin). V soucasnosti patri pozemek byvalych lazni, ve kterem je i lazenska studna, obci Petrov u Straznice. Mimo lazenskou studnu byl sirovodik zjisten i v dalsich studnach v obci (napr. studna u sklepu v Plzich, studna u hrbitova).
Lazenska studna ("pramen Petrov") je situovana ve fluvialnich sedimentech udolni nivy Moravy. Puvod sirovodiku v teto mineralni vode neni uspokojive vysvetlen. Predpoklad, ze jde o dusledek redukcni cinnosti desulfurikacnich bakterii, ktere redukuji sirany z podzemni vody za pritomnosti organicke hmoty ve fluvialnich sedimentech, se vzhledem k stabilite a stari zdroje jevi jako neprilis pravdepodobny.
Mineralni voda "pramene Petrov" byla jimana v arealu lazni studnou o prumeru 1,2 m a hloubce 3 m. Jeji vydatnost neni presne znama. Podle maximalni denni spotreby mineralni vody pri realizaci 100 az 120 koupeli po 250 l (tj. 30 000 l) a osmihodinovem provozu, lze predpokladat, ze vydatnost studny se blizila hodnote 1 l/s.
Z analyzy ze dne 22. 10. 1972 vyplyva, ze voda ma mineralizaci 760 mg/l, je Ca-HCO3-SO4 typu. Obsah sulfanu (sirovodiku) cinil 8 mg/l. Mineralni voda je studena (T = 12°C). V analyzach z roku 2000 byl stanoven obsah sulfanu na 1,90, resp. 2,30 mg/l, pricemz celkova mineralizace vzrostla na 986 mg/l. Voda byla stejneho chemickeho typu. Voda je tedy dle vyhlasky 423/2001 Sb., prrl. 1, sirna, stredne mineralizovana.
V roce 1961 byl "pramen Petrov" vyhlasen za prirodni lecivy zdroj mineralni vody. V soucasne dobe ma statut osvedceneho prirodniho leciveho zdroje mineralnich vod, vhodneho pro leceni nemoci jako revmatismus, ischias, zanety nervu a ekzemy, ktere lze lecit koupelemi, pitnou kuru by bylo mozne aplikovat pro nemoci zaludecni (jde pouze o udaje orientacni).

Petrov Spa - Mineral Spring
In Petrov by Straznice was sulfur mineral water (content H2S > 2 mg/l) used for therapeutical purposes in the Middle Ages, when Thomas Jordan refers to the Petrov's mineral water in his book from 1580. Spa was still popular in the 70th of the twentieth century. Its decline and gradual disappearance was linked to the opening of spa in Hodonin (both spas fall under OUNZ Hodonin). The land where the former spa and well were located currently belongs to the village of Petrov by Straznice. Beside the spa well has been hydrogen sulfide detected in other wells in the village (e.g. well in the vine cellars Plze and well at the cemetery). The Spa well is located in the fluvial sediments of the bottom land of Moravia.
Mineral water "Petrov spring" was accumulated in the spa area, well with a diameter of 1.2 m and depth of 3 m. According to the maximum daily consumption of mineral water 100 - 120 baths 250 l per bath (i.e. 30,000 liters) and an eight hour operation, we can assume that the capacity of the well is close to 1 l/s.
A study from 1972 says that water mineralization is 760 mg/l, Ca-HCO3-SO4 type. Content of hydrogen sulfide is 8 mg/l. Mineral water is cold (T = 12°C). The analysis from 2000 hydrogen sulfide content was determined at 1.90, respectively. 2.30 mg/l, the total mineralization increased to 986 mg/l. Water was of the same chemical type. Water is therefore sulfur, medium-mineralized.
In 1961 was "Petrov spring" declared a natural source of medicinal mineral water. Currently it has a proven status of resource of natural therapeutic mineral water, suitable for treating diseases such as rheumatism, sciatica, neuritis, and eczema, which can be treated with baths, drinking cure could be applied for gastric diseases.
