Erratum to: Environ Monit Assess DOI 10.1007/s10661-010-1399-2 The original version of this article unfortunately contained a mistake in Table 1 and Eqs. 1 and 5. The corrected Table 1 and equations are given below:   cations − anions  × 100 E=  cations + anions SSP = 

Na+ Na+ + Ca2+ + Mg2+

 × 100
