Summary
Groundwater in Sidi Slimane, Morocco, is largely unsuitable for drinking due to high salinity and hardness. Urgent measures are needed to control pollution from agricultural practices to protect this vital water source.
Area of Science:
- Environmental Science
- Hydrogeology
- Water Quality Assessment
Background:
- Groundwater is a critical drinking water source, necessitating protection from contamination.
- The Sidi Slimane region in western Morocco is a key agricultural hub.
Purpose of the Study:
- To evaluate the potability of groundwater in the Sidi Slimane region.
- Assess groundwater quality for human consumption.
Main Methods:
- Collected and analyzed 20 groundwater samples using standard methods (APHA).
- Measured major ions, ammonium, pH, and electrical conductivity (EC).
- Calculated total dissolved solids (TDS) and total hardness (TH); used ArcGIS for mapping.
Main Results:
- Groundwater exhibited high concentrations of parameters exceeding drinking water standards.
- Water was brackish and very hard, dominated by sodium and chloride ions.
- Salinity was found at shallow depths, with 90% of samples being sodium chloride type.
Conclusions:
- The majority of groundwater samples demonstrated poor quality for drinking purposes.
- Exceedances of Moroccan drinking water standards were noted for sodium, calcium, TDS, EC, chlorine, and nitrate.
- Recommendations include controlling agricultural pollutants (pesticides, fertilizers, manure) and irrigation practices to safeguard groundwater quality.

In concrete preparation, the quality of water is paramount as it affects the strength and durability of the concrete. Potable water is usually preferred; however, it must not have excessive sodium or potassium to prevent compromising the concrete's integrity. Water quality is typically evaluated based on impurities such as dissolved solids, chlorides, and sulfates, and its pH value is ideally between 6 and 8. Even slightly acidic natural water may be acceptable unless it contains harmful...

303
When the quality of water for concrete preparation is uncertain, its impact on the setting time of cement and compressive strength of mortar is assessed by comparison with de-ionized or distilled water benchmarks. American Society for Testing and Materials (ASTM) C1602 requires the setting times to be within 90 minutes of the control, British Standard (BS) 3146:1980 allows a 30-minute variance in the initial setting, while British Standards European Norm (BS EN) 1008 specifies initial setting...
