Differences
In everyday language, minimal difference. In technical plumbing contexts, 'blackwater' is understood but UK professionals may also use 'foul water' or 'sewage'. The US is more likely to use 'blackwater' in security/military discourse due to the company's prominence in US foreign policy.
Connotations
UK: Slightly more likely to evoke the natural/landscape meaning (e.g., 'blackwater rivers' in peatlands). US: Stronger immediate association with the private military company due to extensive media coverage.
Frequency
Very low frequency in general English. Much higher frequency in US political/security journalism (2004-2010) and in specific technical fields (environmental science, plumbing).
