Notes
Sample Condition: CLEAR
Field Remarks: SAMPLEL COLLECTED @ END OF 72HR AQUIFER TEST SAMPLE FROM PROPOSED AUTUMN RIDGE SUBDIVISION WELL SCB WITH PRODUCTION ZONE OPEN (440FT-502FT)
Lab Remarks:
Explanation: mg/L = milligrams per Liter; µg/L = micrograms per Liter; ft = feet; NR = No Reading in GWIC
Qualifiers: J = Estimated quantity above detection limit but below reporting limit; P = Preserved sample; S = Method of standard additions; U = Undetected quantity below detection limit; * = Duplicate analysis not within control limits; ** = Sum of Dissolved Constituents is the sum of major cations (Na, Ca, K, Mg, Mn, Fe) and anions (HCO3, CO3, SO4, Cl, SiO2, NO3, F) in mg/L. Total Dissolved Solids is reported as equivalent weight of evaporation residue.
