It forms when iron in soil and groundwater reacts under favourable conditions. <\/p>\n\n          <p> Deposits may appear viscous or gelatinous and accumulate in foundation drains, sump pits and around pumps. <\/p>\n\n          <div class=\"lab-ocre-subtopic lab-analysis-subtopic\">\n\n            <h4> Chemical and biological formation <\/h4>\n\n            <p> Iron ochre can form through a chemical process, a biological process or a combination of both. <\/p>\n\n            <p> The chemical process involves the oxidation of iron dissolved in water, causing deposits to form. The biological process involves iron bacteria naturally present in the environment. <\/p>\n\n            <p> These bacteria can accelerate deposit formation and contribute to larger accumulations. <\/p>\n\n          <\/div>\n\n          <div class=\"lab-ocre-subtopic lab-analysis-subtopic\">\n\n            <h4> Possible effects on drainage <\/h4>\n\n            <p> A significant buildup of iron ochre can reduce water drainage capacity and contribute to clogged drains. <\/p>\n\n            <p> The resulting water infiltration and excessive moisture can create conditions favourable to mould growth. <\/p>\n\n            <p> Iron ochre itself is not considered a health hazard.
